2 EXECUTIVE SUMMARY Terrapex Environmental Ltd. (Terrapex) was retained by the City of Toronto to conduct a Phase II Environmental Site Assessment (ESA) of the property located at 1300 Wilson Avenue, in Toronto, Ontario (the site). It is understood that the study is required by the City of Toronto as part of its due diligence activities prior to a potential acquisition of the site for future use as an Emergency Medical Services (EMS) ambulance station. This work program was completed to address potential concerns identified during a previous Phase I ESA of the site. The scope of the services provided by Terrapex during the Phase II ESA work program included: advancing a total of three (3) boreholes using a track-mounted Geoprobe 7822DT equipped with standard dual tube samplers and solid stem augers; collecting soil samples during drilling, and submitting selected soil samples for various laboratory analyses, including benzene, toluene, ethylbenzene, and xylenes (collectively, BTEX); the "F1", "F2", "F3", and "F4" general petroleum hydrocarbon (PHC) parameters; selected metallic and inorganic parameters; selected polycyclic aromatic hydrocarbons (PAHs); and polychlorinated biphenyls (PCBs); installing groundwater monitoring wells within all three (3) boreholes and collecting and submitting representative groundwater samples for laboratory analyses of volatile organic compounds (VOCs), including the BTEX parameters; the F1 to F4 PHC parameters; and PCBs; and, evaluating laboratory results using applicable generic site condition standards from the April 11, 2011 version of the Ministry of the Environment (MOE) Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act document (hereafter referenced as the 2011 MOE Standards document). Generic Site Condition Standards applicable to industrial/commercial/community land use and coarse textured soils that are listed in Table 3 of the 2011 MOE Standards document were selected for evaluating laboratory analytical results (the Table 3 Site Condition Standards). On July 31, 2013 three (3) boreholes (MW101, MW102 and MW103) were advanced at the site. All three boreholes were subsequently instrumented as monitoring wells. Groundwater samples were recovered from the newly installed monitoring wells on August 6, Selected soil samples were submitted for analyses of benzene, toluene, ethylbenzene, and xylenes (collectively, BTEX), and the "F1", "F2", "F3", and "F4" petroleum hydrocarbon (PHC) parameters, polycyclic aromatic hydrocarbons (PAHs), selected metals and inorganic parameters and polychlorinated biphenyls (PCBs). Laboratory analyses identified sodium absorption ratio (SAR) in excess of the Table 3 Site Condition Standards within soil sample TERRAPEX ENVIRONMENTAL LTD City of Toronto CT ii

3 MW103-1B. Laboratory analyses did not identified concentrations of any tested parameters in excess of the Table 3 Site Condition Standards in the analysed groundwater samples. The identified SAR impacts in soil likely resulted from the placement of road salt on the site or on neighbouring roadways for the purposes of snow and ice control. Although the Ontario Classes of Contaminants - Exceptions regulation (O. Reg. 339) specifically exempts impacts related to the application of road salt for safety purposes on a highway or equivalent roadway as classification as a "contaminant", it is understood that this exemption is not applicable where road salt is applied to other properties such as a parking lot (as is suspected to be the case for at least some of the identified impacts at the site). The MOE generic Site Condition Standards represent minimum quality criteria at which unacceptable risks or hazards would not be expected for potential receptors. However, the generic Site Condition Standards established by MOE are intended to be applied at a variety of sites across Ontario and are inherently conservative; an exceedence of a generic Site Condition Standard does not necessarily mean that unacceptable risks/hazards are present at the site, merely that they might be present. Potentially problematic exposure pathways, with respect to SAR are limited to ecological receptors in soil (for plants, root uptake; and for soil organisms) only; they are not considered a human health risk or hazard. Consequently, no human health concerns have been identified by the Phase II ESA. With respect to potential ecological receptors, future receptors are expected to be restricted to vegetation and soil organisms similar, if not identical, to those currently at the site. While the exceedences of the SAR parameter suggest the possibility of adverse impact, significant vegetation is present at the site and no evidence of any stressed vegetation or other signs of ecological impact were identified during the Phase I ESA (a study where explicit observation for such conditions is made). Consequently, it does not appear that the environmental conditions of the site are unacceptable for the anticipated ecological receptors. On the basis of this analysis, immediate remediation or other contaminant management efforts at the site is not considered warranted at this time. TERRAPEX ENVIRONMENTAL LTD City of Toronto CT iii

6 1.0 INTRODUCTION Terrapex Environmental Ltd. (Terrapex) was retained by the City of Toronto to conduct a Phase II Environmental Site Assessment (ESA) of the property located at 1300 Wilson Avenue, in Toronto, Ontario (the site). It is understood that the study is required by the City of Toronto as part of its due diligence activities prior to a potential acquisition of the site for future use as an Emergency Medical Services (EMS) ambulance station. The objective of the investigation was to assess potential sources of environmental concern with respect to soil and groundwater quality at the site identified during a previous Phase I ESA. The findings of the Phase I ESA are documented in Terrapex s report entitled Phase I Environmental Site Assessment, 1300 Wilson Avenue, Toronto, Ontario, Final Report, dated August 23, SITE DESCRIPTION AND BACKGROUND The site is located on the north side of Wilson Avenue approximately 200 m east of Lexfield Avenue, in Toronto, Ontario. The site is roughly rectangular in shape, is approximately 3.03 acres (1.23 ha) in size. The site is developed with one a two-storey building, which is currently occupied by St. Noel Chabanel elementary school. The site is owned and operated by Conseil Scolaire de District Catholique Centre-Sud (South-Central District Catholic School Board). Vehicular access to the site is obtained from Wilson Avenue. The surface at the site is asphalt paved with a grassy area to the north of the building. The site is located in a mixed predominantly residential neighbourhood. Occupants of adjoining and neighbouring properties observed at the time of the site inspection are listed below: North: Northeast: East: Southeast: South: Southwest: West: Northwest: Calais Avenue and residential; Roding Park; Apartment building and Pierre Laporte Middle School beyond; Wilson Avenue, apartment building beyond; Wilson Avenue and apartments/convenience store beyond; Wilson Avenue and apartments beyond; Hydro (electrical) substation and residential beyond; and Residential. The nearest mapped watercourse is Black Creek, approximately 800 m west of the site. Black Creek discharges into the Humber River, which flows in a southerly direction into Lake Ontario. Based on the historical records review and site inspection, it appears that a portion of an TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

7 intermittent stream (former tributary of Black Creek) has been channelized and buried below the subject site. Several off-site sources of potential impact to the environmental quality of soil or groundwater at the site were identified during the recent Phase I ESA study: an electrical sub-station is located on the property immediately west of the site; numerous groundwater monitoring wells were also observed at this property; Technical Standards and Safety Authority Records relating to the "discovery of product" at 1303 and 1307 Wilson Avenue (apartment buildings located approximately 20 m south of the site, across Wilson Avenue) were identified, although no other details regarding these instances was provided; and, the Apartment building located on the property immediately east of the site has been granted a Certificate of Approval for the operation of a backup generator, indicating a potential for an above ground or underground fuel storage tank to be present on the property. The site location and the general site layout are presented on Figure 1 and Figure 2, respectively. 1.2 STUDY OBJECTIVES The objective of the Phase II ESA is to evaluate the soil and groundwater quality at the subject site with respect to any potential contaminants identified during the previously completed Phase I ESA. 1.3 SCOPE OF WORK The scope of the services provided by Terrapex during this work program included: advancing a total of three (3) boreholes using a track-mounted Geoprobe 7822DT equipped with standard dual tube samplers and solid stem augers; collecting soil samples during borehole advancement, and logging of soil type, qualitative moisture content and visual/olfactory observations pertaining to petroleum hydrocarbon or other chemical impacts, if any; submitting selected soil samples for laboratory analyses; installing groundwater monitoring wells within all three boreholes; collecting representative groundwater samples from the newly installed wells for laboratory analyses; and, TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

8 evaluating laboratory results using applicable generic site condition standards from the Ministry of the Environment (MOE) Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act document, dated April 15, 2011 (hereafter referenced as MOE Standards). Borehole drilling and monitoring well installation services for this work program were provided by Strata Drilling Group (Strata) of Richmond Hill, Ontario, under contract with Terrapex. Strata is a MOE-licensed well drilling contractor. Laboratory analytical services for this work program were provided by the Maxxam Analytics Inc. (Maxxam) laboratory in Mississauga, Ontario, under contract with Terrapex. The Maxxam facility is accredited by the Standards Council of Canada (SCC) to International Standard ISO/IEC 17025:2005, General Requirements for the Competence of Testing and Calibration Laboratories.

9 2.0 WORK PROGRAM DESCRIPTION 2.1 WORK PROGRAM PREPARATION Prior to drilling, appropriate agencies were contacted to identify the locations of buried utilities at and near the site. Onsite Locates Inc., a private underground cable and pipe locating contractor, was retained by Terrapex to provide clearance with respect to buried private utilities at the borehole locations and to confirm the location of public utilities in the vicinity of the boreholes. A site-specific health and safety plan (HASP) was also prepared by Terrapex prior to commencing field work. All team members, including sub-contractors, read and signed the HASP before working at the site. 2.2 BOREHOLE DRILLING Three (3) boreholes (MW101, MW102 and MW103) were advanced at the site by Strata on July 31, 2013 using a Geoprobe 7822DT drill rig, equipped with standard dual tube samplers and probe rods with disposable liners. To facilitate monitoring well installations, the Geoprobe 7822DT was also equipped with solid stem augers which were employed following the completion of soil sampling and immediately prior to monitoring well installation. Borehole advancement was supervised full-time by Terrapex personnel. Borehole locations were selected to investigate potential impacts to soil and groundwater associated with the findings of the Phase I ESA as summarized in Section 1.1, as well as achieving general site coverage. When selecting borehole locations, consideration was given to the locations of buried utilities and above grade infrastructure. Borehole locations are shown on Figure 2. During drilling, soil samples were collected at regular depth intervals using 50 mm nominal diameter split spoon, and dual tube samplers with disposable liners, 1.22 m in length. Each recovered sample was divided into two portions, with one portion placed in a clear sampling bag for field screening/logging, and the second portion placed in laboratory-supplied sampling containers for possible laboratory analyses. Soil vapour concentrations were measured in the headspace of each sampling bag using a RKI Eagle hydrocarbon surveyor, calibrated to n-hexane and operated in methane elimination mode. To mitigate cross-contamination, fresh disposable liners were employed for each sample recovery effort (as applicable), and fresh nitrile gloves were donned for the handling of each sample. A total of seven (7) soil samples from the boreholes were selected and submitted for laboratory analyses as follows: TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

10 Three (3) samples for analyses of benzene, toluene, ethylbenzene, and xylenes (collectively, BTEX), and the "F1", "F2", "F3", and "F4" petroleum hydrocarbon (PHC) parameters; Two (2) soil samples for selected polycyclic aromatic hydrocarbons (PAHs); Two (2) samples for analysis of selected inorganic and metallic parameters; One (1) soil sample for polychlorinated biphenyls (PCBs); and, One (1) composite sample representative of the borehole cuttings was submitted for analysis of PCBs, selected volatile organic compounds (VOCs), and selected inorganic parameters within a Toxicity Characterization Leachate Procedure (TCLP) leachate prepared in accordance with O. Reg. 347 (General - Waste Management). A field duplicate of sample MW102-6 (identified as sample ABH ), and a field blank sample (identified as "MW100") were also submitted for laboratory analysis as field program quality assurance/quality control (QA/QC) measures. The laboratory was not informed of the nature or number of Terrapex field QA/QC sample submissions, although the nature of sample MW100 (a blank sample, therefore comprising a container containing sample preservative but lacking any soil material) would likely have been obvious to the laboratory at the point of sample reception. Submitted samples were placed into a cooler with ice and delivered to the laboratory under signed chain of custody. Soil sampling results are discussed in Section 3. Graphical borehole logs illustrating the stratigraphy encountered and measured soil vapour concentrations readings are included in Appendix I. 2.3 MONITORING WELL INSTALLATION Boreholes MW101, MW102 and MW103 were each instrumented as a monitoring well using 50 mm nominal diameter, schedule 40 PVC well pipe and #10 slotted well screen. The annulus of each well was backfilled with #1 (MW101) or #2 (MW102 and MW103) washed silica sand to a depth of approximately 0.3 m above the screened interval. A bentonite seal was placed above the sand pack to prevent infiltration of surface water into the monitoring well. The standpipe of each well was sealed and locked with a locking AJ-plug@ expandable gripper-style cap. A flush-mount protective casing, cemented in place, was installed at each well. Following installation, each monitoring well was instrumented with a dedicated inertial sampler comprising low density polyethylene (LDPE) tubing and a LDPE foot valve.

11 Monitoring well locations are illustrated in Figure 2. Borehole logs illustrating the monitoring well construction details are included in Appendix I. 2.4 WELL DEVELOPMENT, GROUNDWATER MONITORING AND SAMPLING Well development, groundwater monitoring and sampling of monitoring wells MW101, MW102 and MW103 was conducted on August 2 and 6, Well Development The wells were developed in order to remove entrained particulate in the well standpipe, well screen and filter pack as well surrounding formation materials. The development was conducted until the wells yield water free of visible particulate (and involving, at a minimum, the removal of at least three borehole volume of water), or until a "dry" condition was encountered for three consecutive cycles. Well Monitoring Immediately upon removal of the well standpipe cap, headspace combustible readings were monitored using a Gastechtor TM 1238ME and a RKI Eagle Hydrocarbon Surveyor, calibrated to n-hexane and operated in methane elimination mode. The depth to water and to the bottom of the well in each well was subsequently measured using a water level meter. Well Sampling Following monitoring, the wells were purged using a 12-Volt peristaltic pump equipped with polyethylene tubing. Physical parameters (temperature, ph, electrical conductivity (EC), dissolved oxygen (DO) and redox potential (ORP)) were recorded during purging using a flow-through cell and a YSI 556 groundwater quality sensor. Purging was conducted until the parameters had "stabilized" (as defined within Terrapex standard operating procedures). Following well recovery, groundwater samples were collected directly into pre-cleaned, laboratory-supplied sampling bottles, packed in a cooler with ice, and shipped under signed chain of custody to Maxxam for laboratory analysis. A field duplicate of the sample recovered from monitoring well MW101 (identified as sample AMW1001"), as well as a trip blank sample (ATrip Blank ) and a trip spike sample ( Trip Spike ) provided by Maxxam, were submitted for laboratory analyses as field program QA/QC measures. With the exception of the trip blank and trip spike samples, the laboratory was not informed of the nature or number of the Terrapex field QA/QC sample submissions. With the exception of the trip blank and trip spike samples, each submitted sample was analysed for VOCs (a testing suite that includes the BTEX parameters), and the F1 to F4 PHC TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

12 parameters. The groundwater samples obtained from MW101 was also analyzed for PCBs. The trip blank and trip spike samples were each submitted for analyses of VOCs. Groundwater monitoring and sampling results are discussed in Section ELEVATION SURVEYING Elevation surveying for each newly installed wells was not conducted as part of this work program. 2.6 SOIL AND GROUNDWATER STANDARDS SELECTION Generic soil and groundwater Site Condition Standards listed in the MOE Standards document were selected for evaluating laboratory analytical results using the criteria established by the current Record of Site Condition Part XV.1 of the Act regulation (O. Reg. 153/04, as amended). These standards reflect current Site Condition Standards considered to be applicable to the site. Results of the soil and groundwater standards selection process are discussed in Section 3. TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

13 3.0 RESULTS 3.1 SUBSURFACE CONDITIONS SOIL A surface asphalt layer was encountered at all borehole locations. The surface asphalt layers were generally underlain by fill, consisting of sand and gravel to depths ranging between 0.8 m and 1.9 m below grade (m bg). Fills were underlain by a silty sand and/or a clayey sandy silt layer which ranged from 0.3 m to 0.9 m in thickness. The sandy silt and or clayey sandy silt was generally underlain by fine to coarse sand to the maximum depth of the boreholes, ranging between 4.6 m and 7.8 m bg. The stratigraphy encountered in each borehole is described on the borehole logs provided in Appendix I. Combustible soil vapour concentrations measured on recovered soil samples ranged from < 10 parts per million by volume (ppm) to 13% of the lower explosive limit (LEL) GROUNDWATER CSV readings within the headspaces of monitoring wells MW101, MW102 and MW103 on August 2, 2013 ranged between 11% LEL and 53% LEL. The CSV readings on August 6, 2013 ranged between 210 ppm and 380 ppm. Depths to groundwater were measured during each monitoring event. Full recoveries of groundwater levels were observed on August 6, On this day, depths to groundwater ranged between 3.57 m (MW103) and 6.63 m (MW102) below top of pipe. Neither light, non-aqueous phase liquid (LNAPL) nor hydrocarbon sheen were encountered during monitoring, purging, or sampling of the monitoring wells during this work program. A summary of the groundwater monitoring results is provided in Table SOIL AND GROUNDWATER STANDARDS SELECTION The site specific details which formed the basis of the soil and groundwater standards selection are summarized below. greater than 2 m of overburden was observed during the work program; TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

14 laboratory testing of soil ph (refer to Section and Table 4) did not identify any results less than 5 or greater than 9; the site is not within, or adjacent to an area of ANatural Significance@ (as defined by O. Reg. 153/04), or otherwise considered Apotentially sensitive@; the site is not located within 30 m of a water body; the current land use of the site, as defined within O. Reg. 153/04, constitutes industrial/commercial/community land use; stratified site conditions will not be used when evaluating laboratory analytical results; the site and surrounding properties within 100 m of the site are municipally serviced with a drinking water supply derived exclusively from surface water sources (Lake Ontario); and, grain size analyses was not conducted as part of the work program. However, based on the predominantly sandy native material observed during the work the Site Condition Standards for coarse textured soil will be used when evaluating laboratory analytical results. The preceding information and assumptions suggest that soil and groundwater standards applicable for industrial/commercial/community land use, coarse textured soils, in a nonpotable groundwater condition that are listed in Table 3 of the MOE Standards should be used to evaluate laboratory analytical results at this time. It should be noted that O. Reg. 153/04 requires proponents, prior to filing a Record of Site Condition, to notify the City of Toronto of the intention to apply non-potable groundwater standards at a property. The regulation also allows thirty days for municipalities to object to the proposed use of non-potable standards, in which case the objection must be withdrawn or standards applicable for a potable groundwater condition must be used. Formal notification of the use of non-potable standards at the site have not be submitted to the City of Toronto, as it is not intended to file a Record of Site Condition for the site at this time. However, it is not expected that the City of Toronto would object to the use of non-potable standards at the site. 3.3 ANALYTICAL RESULTS SOIL Laboratory results for the soil samples submitted to Maxxam for analyses of BTEX and the PHC parameters, PAHs, selected metals and inorganic parameters, PCBs, and the results of the TCLP leachate testing are summarized in Tables 2 through 5, respectively. The corresponding MOE Table 3 Site Condition Standards are also provided in Table 2 TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

15 through 4, while the hazardous waste classification criteria from Schedule 4 of O. Reg. 347 are provided in Table 6. BTEX and PHC F1 to F4: As shown in Table 2, a total of three soil samples were submitted for laboratory testing of BTEX and the F1 to F4 PHC parameters. Concentrations of BTEX and PHC parameters were not detected in the analysed samples and were therefore below the MOE Table 3 Site Condition Standards. PAHs: As shown in Table 3, a total of two soil samples were submitted for analyses of PAHs. Concentrations of PAHs were not detected in the analysed samples and were therefore below the MOE Table 3 Site Condition Standards. Metallic and Inorganic Parameters: As shown in Table 4, a total of two soil samples were submitted for laboratory analyses of metallic and inorganic parameters. Concentrations of the tested parameters exceeded the MOE Table 3 Site Condition Standards in one of the soil samples submitted for analysis as described below: Sodium Adsorption Ratio: The sodium adsorption ratio (SAR) exceeded the MOE Table 3 Site Condition Standard in soil sample MW103-1B. PCBs: As shown in Table 4, one soil sample was submitted for laboratory analyses of PCBs. Concentrations of PCBs were not detected in the analysed sample and were therefore below the MOE Table 3 Site Condition Standards. Waste Characterization: As shown in Table 5, one composite soil sample was submitted for waste characterization analyses within a TCLP leachate. Analytical results indicate that soil cuttings generated during this assessment may be considered non-hazardous waste for the purposes of off-site disposal. QA/QC sampling results are described below. Laboratory Certificates of Analysis for the analysed soil samples are included in Appendix II GROUNDWATER Laboratory results for the groundwater samples submitted to Maxxam for analyses of VOCs (including the BTEX compounds), the PHC parameters, and PCBs are summarized in Tables 6, 7, and 8, respectively. The corresponding MOE Table 3 Site Condition Standards are also provided in the tables. VOCs: As shown in Table 6, in three groundwater samples were submitted for laboratory analyses of VOCs. Concentrations of VOCs (including BTEX) in the analysed samples were each less than the MOE Table 3 Site Condition Standards. TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

16 Petroleum Hydrocarbon F1 to F4 Fractions: As shown in Table 7, three groundwater samples were submitted for laboratory analyses of the F1 to F4 PHC parameters. Concentrations of the tested parameters were not detected in the analysed samples and were therefore less than the MOE Table 3 Site Condition Standards. Polychlorinated Biphenyls: As shown in Table 8, one groundwater sample was submitted for laboratory analyses of PCBs. Concentrations of PCBs were not detected in the analysed sample and were therefore less than the MOE Table 3 Site Condition Standard. QA/QC sampling results are described below. Laboratory Certificates of Analysis for the analysed groundwater samples are included in Appendix II QA/QC RESULTS QA/QC samples submitted by Terrapex consisted of one field duplicate soil sample, one field duplicate groundwater sample, one field blank soil sample (methanol blank), one trip blank water sample and one trip spike water sample. Acceptable correlation was observed between the analytical results for soil sample MW102-6 and its field duplicate BH102-66, as well as groundwater sample MW101 and its field duplicate MW1001 for the analyzed parameters. Concentrations of the analyzed parameters were not detected in either the methanol blank sample or trip blank water sample. Acceptable recoveries of the target compounds were reported by the laboratory for the trip spike water sample. Analytical results for the trip blank and the trip spike water samples are summarized in Table 6. Maxxam s Quality Assurance/Quality Control (QA/QC) program consisted of the analyses of laboratory replicates, process and method blanks, process percent recoveries, matrix spikes, method spikes, and surrogate percent recoveries, as appropriate for the particular analysis protocol. QA/QC Control Limits: A review of the quality assurance reports attached to the laboratory certificates of analysis indicate that the laboratory QA/QC program results were generally within quality control limits. Matrix Spike Recoveries: In several instances, the laboratory did not calculate matrix spike recoveries: TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

17 For chromium in Maxxam QA/QC batch (applicable to Terrapex soil samples MW102-1A and MW103-1). For barium, copper, lead, nickel, vanadium and zinc in Maxxam QA/QC batch (applicable to Terrapex soil samples MW102-1A and MW103-1). In each case, the laboratory attributed the lack of QA/QC data to relatively high concentrations of the spiked compound in the parent sample (which may be a sample other than one of the Terrapex submissions), resulting in a relative difference between the spiked and un-spiked concentrations that is insufficiently significant to permit a reliable recovery calculation. No particular concerns are attributed to these situations, as they represent instances in which some QA/QC data is unavailable, rather than QA/QC failures. Detection Limits: Due to the nature of the sample matrix, some samples required dilution and detection limits were adjusted accordingly: Soil samples MW101-1A for PAH analysis; and, Groundwater samples MW101 for PCBs analysis. The adjustments of the detections limits are not considered a significant concern with respect to QA/QC as all reported non-detected results were below the corresponding MOE Table 3 Site Condition Standards.

18 4.0 SUMMARY AND CONCLUSIONS On July 31, 2013 three (3) boreholes (MW101, MW102 and MW103) were advanced at the site. All three boreholes were subsequently instrumented as monitoring wells. A total of seven (7) soil samples from the boreholes were selected and submitted for laboratory analyses as follows: Three (3) samples for analyses of BTEX and PHC parameters; Two (2) soil samples for selected PAHs; Two (2) samples for analysis of selected inorganic and metallic parameters; One (1) soil sample for PCBs; and, One (1) composite sample representative of the borehole cuttings was submitted for analysis of PCBs, selected VOCs, and inorganic within a TCLP leachate prepared in accordance with O. Reg On August 6, 2013 groundwater samples were recovered from each of the newly installed monitoring wells (MW101, MW102 and MW103). As outlined in Section 3.2, the information and assumptions for this site suggest that soil standards applicable for industrial/commercial/community land use in a non-potable groundwater condition and coarse textured soil that are listed in Table 3 of the April 15, 2011 version of the MOE Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act document should be used to evaluate laboratory analytical results. Selected soil samples were submitted for analyses of BTEX and PHC F1-F4 parameters, PAHs, selected metals and inorganic parameters and PCBs. Laboratory analyses identified SAR in excess of the Table 3 Site Condition Standards within soil sample MW103-1B. Laboratory analyses did not identified concentrations of any tested parameters in excess of the Table 3 Site Condition Standards in the analysed groundwater samples. The elevated SAR parameter would not permit the filing of a Record of Site Condition at this time. The identified SAR impacts in soil likely resulted from the placement of road salt on the site or on neighbouring roadways for the purposes of snow and ice control. Although the Ontario Classes of Contaminants - Exceptions regulation (O. Reg. 339) specifically exempts impacts related to the application of road salt for safety purposes on a highway or equivalent roadway as classification as a "contaminant", it is understood that this exemption is not applicable where road salt is applied to other properties such as a parking lot (as is suspected to be the case for at least some of the impacts identified at the site). It is understood that the City intends to acquire the site through its Delegation of Authority in Certain Real Estate Matters policy adopted by City Council in 2010, which notes that authority to acquire property is conditional upon provision being made to bring the property into TERRAPEX ENVIRONMENTAL LTD City of Toronto CT

19 compliance with applicable MOE or other requirements such that it will be fit for its intended municipal purpose. As the City s intended use of the site (EMS Ambulance Station) does not constitute a change to a more sensitive land use (per the meaning of the Environmental Protection Act and O. Reg. 153/04 under the Act), the intending municipal use will not require the filing of a Record of Site Condition. Consequently, the City Delegation of Authority in Certain Real Estate Matters policy is understood to require that either: the environmental conditions of the site not represent a potential risk or hazard to potential receptors associated with the intended land use; or, the City have available to it the necessary resources to restore the site to the above condition. The MOE generic Site Condition Standards represent minimum quality criteria at which unacceptable risks or hazards would not be expected for potential receptors. As noted above, exceedences of these standards have been documented for EC and SAR in soil. However, the generic Site Condition Standards established by MOE are intended to be applied at a variety of sites across Ontario and are inherently conservative; an exceedence of a generic Site Condition Standard does not necessarily mean that unacceptable risks/hazards are present at the site, merely that they might be present. Potentially problematic exposure pathways, with respect to SAR are limited to ecological receptors in soil (for plants, root uptake; and for soil organisms) only; they are not considered a human health risk or hazard. Consequently, no human health concerns have been identified by the Phase II ESA. With respect to potential ecological receptors, future receptors are expected to be restricted to vegetation and soil organisms similar, if not identical, to those currently at the site. While the exceedences of the SAR parameter suggest the possibility of adverse impact, significant vegetation is present at the site and no evidence of any stressed vegetation or other signs of ecological impact were identified during the Phase I ESA (a study where explicit observation for such conditions is made). Consequently, it does not appear that the environmental conditions of the site are unacceptable for the anticipated ecological receptors. On the basis of this analysis, immediate remediation or other contaminant management efforts at the site is not considered warranted at this time, and the environmental condition of the site would not appears to preclude the City from acquiring the property under the Delegation of Authority in Certain Real Estate Matters policy.

Used to evaluate the variance in the measurement. Matrix Spike: A sample to which a known amount of the analyte of interest has been added. Used to evaluate sample matrix interference. QC Standard: A sample of known concentration prepared by an external agency under stringent conditions. Used as an independent check of method accuracy. Spiked Blank: A blank matrix sample to which a known amount of the analyte, usually from a second source, has been added. Used to evaluate method accuracy. Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination. Surrogate: A pure or isotopically labeled compound whose behavior mirrors the analytes of interest. Used to evaluate extraction efficiency. NC (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and the spiked amount was not sufficiently significant to permit a reliable recovery calculation. NC (RPD): The RPD was not calculated. The level of analyte detected in the parent sample and its duplicate was not sufficiently significant to permit a reliable calculation. (1) - Recovery or RPD for this parameter is outside control limits. The overall quality control for this analysis meets acceptability criteria. (2) - The matrix spike recovery was below the lower control limit. This may be due in part to the reducing environment of the sample. (3) - The recovery in the matrix spike was not calculated (NC). Spiked concentration was less than 2x that native to the sample. Page 14 of 16
