(Pinchin) to conduct a hazardous building materials assessment of the building, located at 240 Manor Road East, Toronto, Ontario. The assessment was performed by Andrew Quinn, B.Sc., on August 24, The surveyor was unaccompanied during the assessment. The building was occupied at the time of the assessment. The objective of the assessment was to identify specified hazardous building materials in preparation for building demolition. This assessment is intended to be used for pre-demolition purposes only, and may not provide sufficient detail for long term management of hazardous materials as required by Health and Safety regulations. The results of this assessment are intended for use with a properly developed scope of work and performance specification. 1.1 Scope of Assessment The assessment was performed to establish the location and type of specified hazardous building materials incorporated in the structure(s) and its finishes. The assessed area was limited to the parts of the building within the area to be demolished: the Montessori school and breezeway connecting the school to the Church. The extent of the assessed area was defined by the Client and is shown on the appended drawings. For the purpose of the assessment and this report, hazardous building materials are defined as follows: Asbestos Lead Silica Mercury The assessment also included: Polychlorinated Biphenyls (PCBs) Mould The following Ontario Designated Substances are not typically found in building materials in a composition/state that is hazardous and were not included in this assessment: Arsenic Acrylonitrile Benzene Coke oven emissions 2016 Pinchin Ltd. 7 of Page 54 1 of 17

9 Hazardous Building Materials Assessment March 30, Manor Road East, Toronto, Ontario Pinchin File: City of Toronto 3.0 FINDINGS 3.1 Asbestos Suspect Building Materials Not Found The following types of building materials may historically contain asbestos but were not observed in the building and are not discussed in the report findings: Spray-applied fireproofing or thermal insulation Texture finishes (acoustic/decorative) Vinyl sheet flooring Firestopping Thermal Systems Insulation (TSI) Pipe Insulation A white corrugated paper insulation (trade name Aircell), containing chrysotile asbestos, is present on straight sections of hot water heating system pipes (Pinchin 2015). There is approximately 30 linear feet of accessible Aircell (boy s washroom, foyer, and below stairs in foyer). Presume that all hot water heating pipes are insulated with Aircell insulation on the straights and parging cement on the fittings. The insulated hot water heating pipes are present inside columns, risers and ceiling spaces and other inaccessible spaces for the perimeter radiators on the first and second levels of the building. Visible, but inaccessible pipes (above solid ceilings, in chases, in column enclosures and within concrete block shafts ceiling and wall spaces) appear to be insulated with Aircell and parging cement on fittings (i.e., elbows, tees, valves etc.). Inaccessible parging cement could not be sampled, and therefore is to be assumed to contain asbestos. Aircell is a friable insulation, jacketed with canvas and is in good condition. Parging cement is a friable insulation, which did not appear to be covered with a jacket, but is in good condition. Quantities of concealed asbestos-containing pipe insulation could not be determined Pinchin Ltd. 9 of Page 54 3 of 17

No insulated mechanical equipment is present in the assessed area Acoustic Ceiling Tiles One visually distinct type of ceiling tile is present in the assessed area. A 12 x 12 tile is attached (nailed) to the ceilings of the classrooms and storage areas on the lower level. The tile was visually identified as a non-asbestos wood fibre. No sampling was performed Pinchin Ltd. 10 Page of 54 4 of 17

11 Hazardous Building Materials Assessment March 30, Manor Road East, Toronto, Ontario Pinchin File: City of Toronto Photo 5: Wood-fibre ceiling tiles in a classroom on the lower level. Ceiling tiles were not observed in other portions of the assessed area Plaster Plaster is present on perimeter (i.e., occupied side of exterior walls) walls and columns and ceilings on both levels. Seven samples of plaster (samples A0003A-G) were collected. Four sample were found to contain chrysotile asbestos in the white finish coat, and three samples were found not to contain asbestos. Based on the sampling results all plaster is to be treated as asbestos-containing. Approximately 4500 SF are present throughout the assessed area. Plaster is non-friable while in place, but generates friable dust upon removal. Photo 6: Plaster on a column on the lower level hallway. Photo 7: Plaster walls in a storage room on the upper level Drywall Joint Compound Non-asbestos joint compound is present on drywall (gypsum board) walls and ceilings at select interior portions of the lower level. Drywall finishes were not observed on the upper level. Three samples of joint compound were previously collected (samples A0002A-C) one of which (sample A0002B) was found to contain chrysotile asbestos. During this assessment four samples were collected, all of which were found not to contain asbestos (A0002D-G) Pinchin Ltd. 11 Page of 54 5 of 17

Prepare plans and specifications for hazardous material removal which will or may be affected by the planned work or is otherwise scheduled for removal. The specifications should include and address the scope of work, safe work practices, personal protective equipment, respiratory protection, and disposal of waste materials. 2. Investigate any items excluded from the scope of work of this report. Ideally this investigation will be performed as part of the development of the specifications, or at a minimum immediately prior to commencing renovations when the areas are no longer occupied. Specifically, the following materials/areas need to be investigated: Vermiculite inside concrete block walls that are to be demolished. Concealed Transite on building exterior. Concealed and inaccessible pipe insulations. 3. Provide this report and the detailed plans and specifications to the contractor prior to bidding or commencing work. 4. Retain a qualified consultant to specify, inspect and verify the successful removal of hazardous materials Pinchin Ltd. 20 Page of 5414 of 17

21 Hazardous Building Materials Assessment March 30, Manor Road East, Toronto, Ontario Pinchin File: City of Toronto 5. Update the asbestos inventory upon completion of the abatement and removal of asbestos-containing materials. 4.2 Remedial Work We recommend the following remedial work be performed to comply with existing regulations, regardless of proposed construction work due to the condition and location of the material: Material and Quantity Location Recommended Procedure Mould on wood fibre insulation boards behind radiators, up to 25 radiators with approximately 7 SF behind each one Beneath windows throughout the building Level 1 (each) 4.3 Building Demolition or Renovation Work The following recommendations are made regarding demolition or renovation involving the hazardous materials identified Asbestos Remove all asbestos-containing materials (ACM) prior to renovation, alteration, maintenance or demolition work or if ACM may be disturbed by the work. If the identified ACM will not be removed prior to commencement of the work, disturbance of ACM must follow the appropriate asbestos precautions for the classification of work being performed. Asbestos-containing materials must be disposed of at a landfill approved to accept asbestos waste Lead Construction disturbance of lead in paint and coatings (or other materials) may result in over-exposure to lead dust or fumes. The need for work procedures, engineering controls and personal protective equipment will need to be assessed on a project-by-project basis and must comply with provincial standards or guidelines. Performing an exposure assessment during work that disturbs lead in paints and coatings may be able to alleviate the use of some of the precautions specified by these standards or guidelines. Lead-painted items may be a hazardous waste. Test lead-painted materials for leachable lead prior to disposal Pinchin Ltd. 21 Page of 5415 of 17

22 Hazardous Building Materials Assessment March 30, Manor Road East, Toronto, Ontario Pinchin File: City of Toronto Lead-containing items [lead-acid batteries, others] should be recycled when taken out of service or prior to building demolition Silica Construction disturbance of silica-containing products may result in excessive exposures to airborne silica, especially if performed indoors and dry. Cutting, grinding, drilling or demolition of materials containing silica should be completed only with proper respiratory protection and other worker safety precautions that comply with provincial standards or guidelines Mercury Do not break lamps or separate liquid mercury from components. Recycle and reclaim mercury from fluorescent light tubes and thermostats when taken out of service. Light tubes are accepted free of charge at many local recycling depots. Liquid mercury is classified as a hazardous waste and must be disposed of in accordance with local regulations PCBs When light fixtures are removed, examine light ballasts for PCB content. If ballasts are not clearly labelled as non-pcb, or are suspected to contain PCBs; package and ship ballasts for destruction at a federally permitted facility Mould Mould growth was noted in areas affected by the planned work. Use appropriate precautions and protect workers using methods that comply with provincial guidelines. 5.0 LIMITATIONS The work performed by Pinchin was conducted in accordance with generally accepted engineering or scientific practices current in this geographical area at the time the work was performed.

37 Pinchin Ltd. Asbestos Laboratory Certificate of Analysis Project Name: City of Toronto, School & Breezeway Pre Demo 240 Manor Road East, Toronto, ON Project No.: Prepared For: A. Quinn / J. McIntyre Date Received: August 28, 2015 Lab Reference No.: b Date Analyzed: September 4, 2015 Analyst(s): N. Barinque # Samples submitted: 3 # Phases analyzed: 6 Method of Analysis: EPA 600/R-93/116 - Method for the Determination of Asbestos in Bulk Building Materials dated July, 1993 Bulk samples are checked visually and scanned under a stereomicroscope. Slides are prepared and observed under a Polarized Light Microscope (PLM) at magnifications of 40X, 100X or 400X as appropriate. Asbestos fibres are identified by a combination of morphology, colour, refractive index, extinction, sign of elongation, birefringence and dispersion staining colours. A visual estimate is made of the percentage of asbestos present. A reported concentration of less than (<) the regulatory threshold (see chart below) indicates the presence of confirmed asbestos in trace quantities, limited to only a few fibres or fibre bundles in an entire sample. This method complies with provincial regulatory requirements where applicable. Multiple phases within a sample are analyzed and reported separately. Provincial Jurisdiction Ontario, British Columbia, Nova Scotia Quebec Alberta, NWT, Yukon, Nunavut Regulatory Threshold Provincial Jurisdiction Regulatory Threshold 0.5% Manitoba 0.1% friable 1% non-friable 0.1% Saskatchewan 0.5% friable 1% non-friable 1% Newfoundland and Labrador, PEI and New Brunswick 1% All bulk samples submitted to this laboratory for asbestos analysis are retained for a minimum of three months. Samples may be retrieved, upon request, for re-examination at any time during that period. Pinchin Ltd. is accredited by the National Institute of Standards and Technology, National Voluntary Laboratory Accreditation Program (NVLAP Lab Code ) for the 'EPA-600/M : Interim Method for the Determination of Asbestos in Bulk Insulation Samples' and meets all requirements of ISO/IEC 17025:2005. This report relates only to the items tested. NOTE: This test report may not be reproduced, except in full, without the written approval of the laboratory. The client may not use this report to claim product endorsement by NVLAP or any agency of the U.S. Government. This report is valid only when signed in blue ink by the analyst. Vinyl asbestos floor tiles contain very fine fibres of asbestos and may be missed by some laboratories using the PLM method. Internal verification studies performed by Pinchin indicate that the chance of missing asbestos in floor tiles is no higher than about 2%. The vinyl tile study and laboratory documentation on measurement uncertainty is available upon request. The analysis of dust samples by PLM cannot be used as an indicator of past or present airborne asbestos fibre levels. 37 of 54 PINCHIN LTD MILLTOWER CRT, MISSISSAUGA, ON L5N 7W5 TEL: (905) FAX: (905)
