1 October 27, Dundas Corporation 2184 Providence Road Oakville, Ontario L6H 6Z2 Attention: Re: Mr. Zaki Wahbeh Soil and Groundwater Testing 103 Dundas Street West, Oakville, Ontario Dear Mr. Wahbeh: A geotechnical investigation was recently completed by Alston Associates Inc. (AAI), the geotechnical division of Terrapex Environmental Ltd. (Terrapex), of the property located at 103 Dundas Street West in Oakville, Ontario (the site). The geotechnical investigation consisted of the advancement of five boreholes (BH1 to BH5) to a depth of 6.1 m below grade. The borehole locations are presented in Figure 1. One potential environmental concern was identified, which was associated with the potential offsite migration of petroleum hydrocarbon (PHC) contaminants from the diesel fuel underground storage tank (UST) at 113 Dundas Street West (located west of the site) onto the site. As such, soil and groundwater samples collected from one of the boreholes (BH4/MW4), which is located along the west property boundary of the site and approximately 25 m east of the existing UST on the west neighbouring property, were inspected for evidence of PHC contamination. Laboratory analytical services for this work program were provided by the AGAT Laboratories Inc. facility in Mississauga, Ontario, under contract with Terrapex. The AGAT 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 for the parameters included in the analytical program. Note that this report, in its current form, cannot be used in support of filing a Record of Site Condition (RSC) for the site. Nonetheless, the soil and groundwater sampling and testing had been completed to a level of technical rigour equivalent to that associated with the requirements of O.Reg. 153/04, and would allow for the preparation of an O. Reg. 153/04 compliant report if filing of a RSC is required in the future (subject to the time restrictions in O. Reg. 153/04).

2 Additional investigation work will be required if a Phase Two Environmental Site Assessment (ESA) report in compliance with the Ontario regulation Records of Site Condition - Part XV.1 of the Act (O. Reg. 153/04) is required to be completed to support filing of a RSC. SOIL SAMPLING During the drilling of borehole BH4 on October 15, 2014, each recovered soil 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 was logged in the field with respect to soil type, qualitative moisture content and visual/olfactory evidence of chemical impact. Combustible soil vapour (CSV) concentrations were measured in each soil sample using a Gastechtor TM 1238ME Hydrocarbon Surveyor, calibrated to n-hexane and operated in methane elimination mode. Two soil samples, including one worst case sample collected close to the water table (BH4 SS5) and one field duplicate sample (BH4 SS50) collected from borehole BH4 were submitted for laboratory analysis of benzene, toluene, ethylbenzene, xylenes (collectively BTEX) and PHC fractions F1-F4. One trip blank soil sample was also submitted for laboratory analysis of BTEX and PHC fraction F1. GROUNDWATER SAMPLING Borehole BH4 was completed as a monitoring well (MW4). The monitoring well was developed on October 20, 2014 to remove drilling debris that may have been introduced during well installation, and to minimize any potential sampling and analytical bias that may result from excessive particulate capture within groundwater samples recovered from these wells. Prior to development, the wells were monitored for combustible vapours (CV) in the well headspace. Depth to water and depth to the bottom of the well were also measured prior to well development. The volume of water in the well and its annulus were calculated based on the depth measurements, diameter of the well standpipe and annulus, and assumed annulus porosity of 30%. Development of the wells was conducted using a dedicated inertial sampler comprising low density polyethylene (LDPE) tubing and a LDPE foot valve. Three borehole volumes (80 L) were purged from MW4. Groundwater samples were collected from the monitoring well MW4 on October 21, Prior to sampling, monitoring activities included the measurement of CV within the headspace of the well immediately upon removal of the well standpipe cap, using a Gastechtor TM 1238ME Hydrocarbon Surveyor, calibrated to n-hexane and operated in methane elimination mode. The depth to water in the well was measured using a Heron interface probe. The presence, and apparent thickness (if applicable), of any light non-aqueous phase liquids (LNAPL) or dense alston associates inc. 103 Dundas Corporation

3 non-aqueous phase liquids (DNAPL) in the well was also assessed using the interface probe. No LNAPL or DNAPL were present. Two groundwater samples, including one representative sample (MW4) and one field duplicate sample (MW104) collected from monitoring well MW4 were submitted for laboratory analysis of BTEX and PHC fractions F1-F4. One trip blank and one trip spike water samples, prepared by the laboratory, were also submitted for laboratory analysis of BTEX and PHC fraction F1. SITE CONDITION STANDARDS SELECTION Generic Site Condition Standards (SCS) were selected from the April 15, 2011 Ontario Ministry of the Environment (MOE) Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act (hereafter referred to as Standards), using the criteria established by Ontario Regulation 153/04, Record of Site Condition Part XV.1 of the Act. The site characteristics relevant to SCS selection are: greater than 2 m of overburden was observed at the site in 4 of 5 boreholes (i.e. greater than 2/3 of the site); the site is not within, or adjacent to an area of Natural Significance (as defined by O.Reg. 153/04), or otherwise considered potentially sensitive ; future use of the site is expected to be residential; the site is serviced with potable water from a groundwater source; the more stringent coarse-textured soil standards were selected for the site even though the natural soil was fine- to medium-textured. stratified site conditions will not be used when evaluating laboratory analytical results. The results of the criteria selection indicate that the appropriate generic criteria for use at the site are those found in Table 2 (Full Depth Generic SCS in a Potable Ground Water Condition), residential/parkland/institutional property use for coarse textured soils (hereafter referred to as MOE Table 2 SCS). RESULTS CSV concentrations in the soil samples were less than 10 ppm. No visual or olfactory evidence of petroleum hydrocarbon impact was observed in any of the soil samples. CV concentration measured within the headspace of the monitoring well was less than 10 ppm. The depth to water in the well was measured at 4.3 m below ground surface. alston associates inc. 103 Dundas Corporation

4 The soil and groundwater samples submitted for laboratory analysis had concentrations of BTEX and PHC fractions F1-F4 below the MOE Table 2 SCS. In fact, all tested parameters had concentrations below the reported detection limit. Copies of the laboratory Certificates of Analysis are attached. QUALITY ASSURANCE/QUALITY CONTROL Terrapex submitted duplicate soil and groundwater samples for QA/QC purposes. Quantitative correlation was not calculable for the BTEX and PHC fractions F1-F4 analytical results of the field duplicate soil samples BH4 SS5 and its sample pair BH4 SS50, as well as the field duplicate groundwater samples MW4 and its sample pair MW104, as the reported concentrations of all parameters for all samples were either equal to or less than five times the reportable detection limits. Detectable concentrations of the tested parameters were not reported in the trip blank soil and water samples. The recoveries of all analysed parameters within the trip spike sample were within acceptance limits. AGAT 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. A review of the quality assurance reports attached to the laboratory certificates of analysis did not indicate any concerns with the laboratory QA/QC program results. Overall, the QA/QC results for the project do not indicate any concerns with data quality. SUMMARY AND DISCUSSION Terrapex conducted an environmental sampling program at 103 Dundas Street West in Oakville, Ontario to investigate the soil and groundwater quality associated with potential off-site migration of PHC contaminants from an existing diesel fuel underground storage tank on the west neighbouring property (113 Dundas Street West). Soil and groundwater samples collected from a borehole/monitoring well located along the west property limit of the site and approximately 25 m east of the UST were selected for laboratory analysis of petroleum-related parameters (BTEX and PHC fractions F1-F4). Based on the results of the laboratory analysis, the soil and groundwater samples collected along the west property limit met the MOE Table 2 SCS for concentrations of BTEX and PHC fractions F1-F4. As such, no evidence of off-site migration of PHC contaminants from the diesel fuel UST on the west neighbouring property was identified. alston associates inc. 103 Dundas Corporation
