Revised Mar 6, 2015 11-10-5203 Summary of Pervious Investigations and Remediation Work Previous investigations for the Property, which were provided to Terraprobe, are summarized below: Report Title Phase I and II Environmental Assessment – Slessor Motors, 17645 Yonge Street North, Newmarket, Ontario Report Date September, 2001 File No. 01-16 Prepared By Alpha Environmental Services Inc. Prepared For Dwight Slessor Holdings Ltd. • The subject property consisted of a single storey commercial/industrial building that was originally constructed in 1962 and was renovated in 1999. The building was heated by natural gas. A showroom was present at the west side of the building and the rear or east side of the building was comprised of a garage with a body and paint shop and full service bays. A gasoline service bar was present at the front (west) side of the property with six underground gasoline storage tanks, two associated pump islands, and a kiosk. New cars are stored on the paved area at the north side of the property. • The building was occupied by Slessor Motors and was used as a car dealership and vehicle service garage with a gasoline service bar operated by Cango at the southwest side of the property fronting onto Yonge Street. • Six underground storage tanks associated with the gasoline service bar were present at the southwest side of the property. • A spill was reported to have occurred in approximately 1988 due to overfilling a tank, and a clean-up was undertaken whereby a considerable amount of contaminated soil was removed from the site up to 4 m below grade. Monitoring wells were installed at the time; however, all the wells were found to be destroyed or compromised at the time of the Alpha Environmental inspection. • Two aboveground storage tanks (approximately 900 L) for new oil with no secondary containment were observed, one at the north interior side of the building and one at the south interior side of the building. • One double-walled aboveground storage tank (approximately 13,600 L) containing waste oil was present at the south exterior side of the building. • A new oil/water interceptor had been installed in approximately May of 2000, and is cleaned out annually by Safety Kleen. • Slessor Motors had been assigned Ontario Waste Generator Number ON2030800 for waste oil, solvents, and waste anti-freeze that are removed by Safety Kleen as needed. Terraprobe Page No 2 Phase Two Environmental Site Assessment 17645 Yonge Street, Newmarket, Ontario Nov 20, 2014. Revised Mar 6, 2015 11-10-5203 • Slessor Motors has been assigned Certificate of Approval 8-3484-93-006 for air emissions from the down-draft oven in the paint shop. • Silty clay fill and silty clay were present in the boreholes to the maximum drilled depth of 5.18 m. • Ground water was encountered in the six drilled boreholes at depths ranging from 1.68 m to 2.10 m below grade. • Relative groundwater elevation measurements indicated that the ground water flow direction is toward the southwest. • Concentrations of benzene and ethylbenzene above the specified Table A guideline limit in the MOE’s Guideline for Use at Contaminated Sites in Ontario were found in the soil samples from four of the boreholes, located south of the retail fuel outlet kiosk and to the south of the USTs, along the southern property boundary. The concentration of toluene in one soil sample from a borehole to the south of the kiosk exceeded the Table A guideline limit. • Several of the ground water samples submitted for laboratory analysis exceeded the Table A guideline limits for benzene, toluene, ethylbenzene and xylene. Report Title Phase II Environmental Site Assessment – 17645 Yonge Street, Newmarket, Ontario Report Date February 28, 2002 File No. 01180 Prepared By Barenco Inc. Prepared For Cango Inc. • The intent of the work was to remove impacted soil identified in the Alpha Environmental report and to ensure that activities that had taken place on the subject property were not a source of adverse environmental effects to adjacent properties. • The report details removal of impacted soil from an area south of the UST nest. Four test pits were excavated and one worst-case soil sample was submitted from each test pit for laboratory analysis of benzene, toluene, ethylbenzene and xylenes (BTEX), and total petroleum hydrocarbons (TPH) in the gas/diesel and heavy oils ranges. Temporary subsurface monitors were installed in two of the test pits and one water sample from each temporary monitor was submitted for analysis of BTEX and TPH in the gas/diesel range. Ground water samples were also submitted from four of the monitoring wells previously installed by Alpha Environmental. The analytical results were compared to the applicable MOE standards in effect at that time as defined in the Ontario Ministry of Environment’s Guideline for Use at Contaminated Sites in Terraprobe Page No 3 Phase Two Environmental Site Assessment 17645 Yonge Street, Newmarket, Ontario Nov 20, 2014. Revised Mar 6, 2015 11-10-5203 Ontario (February 1997). The results were compared to the generic Table A standards for industrial/commercial land use (medium and fine textured soil). • • The results of the investigation were as follows: o All four “worst-case” soil samples submitted from the test pits excavated along the property boundary met the applicable Table A criteria for BTEX and TPH. o Ground water samples taken from the temporary monitors along the southern property boundary exceeded the Table A guideline for benzene. o One ground water sample collected from the monitoring well to the south of the pump island exceeded the Table A guideline for both benzene and ethylbenzene. Barenco concluded in their report that “minor exceedances of petroleum parameters in soil and ground water samples collected from the subject property are not indicative of any significant environmental issues. Rather, the exceedances are indicative of the present of an operating gas bar on the property.” The report also states that “[u]nder the Management Protocol that supports [the Technical Standards and Safety Act], GA1/99, remediation of a gas bar is only required if there is off-site migration of petroleum-related contaminants or if there are unacceptable safety conditions for continued operation… there are no unacceptable safety conditions that would arise under continued operation of the gas bar. No liquid product was observed in any of the ground water samples and the native silty clay surrounding the petroleum handling equipment will prevent migration of petroleum off-site. Hence, it appears that activities that are taking place on the subject property are not a source of environmental impairment on adjacent properties. Accordingly, further clean up activities in the vicinity of the operating gas bar, including soil removal, are neither recommended nor warranted at this time.” • Based on the results of the investigation, ground water along the property boundary exceeded the applicable Standards. There was therefore a high probability that petroleum-related contaminants were migrating off-site. Report Title Environmental Inspection of UST and Pump Island Excavation – Slessor Motors, 17645 Yonge Street, Newmarket, Ontario Report Date September 18, 2009 File No. W2466 Prepared By Winchurch Environmental Inc. Prepared For Cannington Construction Ltd. • The investigation by Winchurch was conducted after the removal of the pump island, piping and USTs associated with the former Cango retail gas bar on the property by Terraprobe Page No 4 Phase Two Environmental Site Assessment 17645 Yonge Street, Newmarket, Ontario Nov 20, 2014. Revised Mar 6, 2015 11-10-5203 Cannington Construction Limited on September 4, 2009. The scope of the work was as follows: • To ascertain the presence and/or extent of any environmental impact in the vicinity of the former USTs, pump islands and piping, • To submit representative “worst-case” assessment soil samples for laboratory analysis, and • To compare the analytical results from the soil samples to applicable site condition standards to confirm/refute regulatory compliance. Ground water was not sampled or tested as part of the investigation. • Winchurch submitted twelve (12) soil samples from the walls and base of the pump island and UST excavations for chemical analysis. Samples were selected for submission based on headspace vapour readings. • The regulatory Standards to which soil results were compared as part of this report are those contained within Table 5 of the Ontario Regulation 153/04 reference document Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act, for industrial/commercial/community use and a medium/fine-textured soil and non-potable ground water condition. These were not the appropriate Standards for the property. The Town of Newmarket derives its drinking water from ground water sources, which means that the ground water should be in a potable condition and the appropriate Standards were those contained in Table 2, not those in Table 5. The report concludes that “[a]n examination of the analytical results indicates that the concentrations of BTEX/PHC measured in the soil samples obtained from the excavation are in compliance with the applicable Table 5 site condition standards for the chemical parameters analyzed.” • Upon comparison of the analytical results with the appropriate Table 2 Standards, several of the soil samples exceeded the Standards for parameters including fraction 1 petroleum hydrocarbons (F1 PHCs), F2 PHCs, benzene, and ethylbenzene. • The report did not recommend further environmental work.

Revised Mar 6, 2015 11-10-5203 Subsurface Structures and Utilities Underground utilities are present on the Property. During the removal of impacted soils, impacts along the utilities were assed and not encountered. Based upon this, it is possible that any potentially contaminated ground water could migrate horizontally along the utilities onto or off the Property. The Property is covered with a hard surface cap. As such, the hard cap will limit infiltration of storm water from the ground surface. Downward migration of contaminates would be limited.

Revised Mar 6, 2015 11-10-5203 3.0 PHYSICAL SETTING OF THE PHASE TWO PROPERTY 3.1 Site Stratigraphy Earth Fill There is a pavement structure consisting of an asphaltic concrete layer that ranged in thickness from 110 to 185 mm overlying an aggregate layer ranging in thickness from 390 to 415 mm. Underlying the surficial pavement structure earth fill was encountered that consists of silt with trace to some clay, trace sand to some sand and trace gravel. The earth fill, where encountered, extends to 1.5 to 4.6 metres below existing grade (Elev. 262.3 to 258.7 metres). The earth fill is generally characterized as being brown, dark brown or brownish grey and moist to wet. Standard Penetration Test results (“N” Values) measured in the earth fill ranged from 2 to 15 blows per 300 mm of penetration indicating a soft to stiff consistency, or a very loose to compact relative density. Upper and Lower Silt Layers Two distinct silt layers were encountered within the boreholes advanced on site, and consist of silt with some clay and trace to no sand. The “upper” silt layer was encountered in near surface, and the “lower” silt layer was encountered in all boreholes between the two glacial till layers (as described in the subsequent section). The silt layers were encountered at the following depths and elevations, and with the following properties: • The upper silt layer was encountered at 0.5 to 2.7 metres below existing grade (Elev. 263.0 to 259.8 metres) and extends to 3.5 to 4.6 metres below existing grade (Elev. 259.2 to 258.6 metres). The upper silt layer is generally characterized as brown and wet. Standard Penetration Test results (“N” Values) measured in the upper silt layer ranged from 4 to 15 blows per 300 mm of penetration, indicating a firm to stiff consistency. Insitu shear vane tests conducted yielded in-situ undrained shear strengths of 96 to greater than 100 kPa. • The lower silt layer was encountered at 10.7 to 12.2 metres below existing grade (Elev. 252.7 to 250.3 metres) and extends to 13.7 to 15.2 metres below existing grade (Elev. 249.8 to 248.6 metres). The lower silt layer is generally characterized as grey and wet. Standard Penetration Test results (“N” Values) measured in the lower silt layer ranged from 7 to 37 blows per 300 mm of penetration, indicating a loose to dense (on average, compact) relative density. Upper and Lower Glacial Till Layers Two distinct glacial till layers were encountered within the boreholes advanced on site and are comprised primarily of a matrix of silt with some clay to clayey, some sand to sandy, and trace gravel. The “upper” glacial till layer was encountered in all boreholes between the two silt layers, and the “lower” glacial till layer was encountered in all boreholes underlying the lower silt layer and extended beyond the vertical Terraprobe Page No 10 Phase Two Environmental Site Assessment 17645 Yonge Street, Newmarket, Ontario Nov 20, 2014. Revised Mar 6, 2015 11-10-5203 extent of investigation (14.2 to 17.2 metres below existing grade). The glacial till layers were encountered at the following depths and elevations, and with the following properties: • The upper glacial till layer was encountered at 3.5 to 4.6 metres below existing grade (Elev. 259.2 to 258.5 metres) and extended to 10.7 to 12.2 metres below existing grade (Elev. 252.7 to 250.3 metres). The upper glacial till layer is generally characterized as brown to grey and moist. Standard Penetration Test results (“N” Values) measured in the upper glacial till layer ranged from 11 to 52 blows per 300 mm of penetration, indicating a stiff to hard consistency. • The lower glacial till layer was encountered at 13.7 to 15.2 metres below existing grade (Elev. 249.8 to 248.6 metres) and extended to beyond the vertical extent of investigation at 14.2 to 17.2 metres below existing grade (Elev. 249.3 to 245.3 metres). The lower glacial till layer is generally characterized as grey and moist to wet. Standard Penetration Test results (“N” Values) measured in the lower glacial till layer ranged from 17 to 40 blows per 300 mm of penetration, indicating a very stiff to hard consistency, but on average is very stiff.

The distribution of the stained soil fill was in the area of the underground services to the oil/water separator. Soil (native) The distribution of petroleum hydrocarbon stained soils were in the vicinity of the oil water separator and the associated piping, including the location of floor drains in the former shop floor. Ground Water Terraprobe Page No 17 Phase Two Environmental Site Assessment 17645 Yonge Street, Newmarket, Ontario Nov 20, 2014. Revised Mar 6, 2015 11-10-5203 Petroleum Hydrocarbons were identified in the ground water in the vicinity of the oil/water separator and the floor drains in the former shop area. 4.7 Distribution of Contaminant Soil (fill) The distribution of the impacts in the soil fill in Impact area 2 was a spill that appeared to originate from surface to a depth of 4 metres below ground surface. Soil (native) The distribution of soils impacts in Impact area 1, extended to a depth of about 4 m below ground surface (into the native soils). Confirmatory soil samples were collected in the area of the excavation to confirm that the lateral and vertical extent of the excavations had been reached. Impact area 2 the remedial excavation extended to a depth of about 4 m below ground surface. Confirmatory soil samples were collected in the area of the excavation to confirm that the lateral and vertical extent of the excavations had been reached. The depth of excavation in Impact Area 3 was 3 m below ground surface. Confirmatory soil samples were collected in the area of the excavation to confirm that the lateral and vertical extent of the excavations had been reached. The location of the excavations to remove the soil and ground water impacts are shown on Figure 7. The location of the confirmatory samples taken in the area of each of the identified Impact Areas is shown on Figure 8, 9, and 10. The vertical extent of the excavations and the location of the former impacts are shown on Figures 11, 12, and 13 for the different identified Impact Areas. Ground Water In the area of the ground water impacts the ground water was excavated as part of the soils removed. Confirmatory ground water samples were taken in monitoring wells in the vicinity of the previously identified ground water impacts (Impact Area 1) and in the vicinity of the location of the former UST (Impact Area 2). The results of the confirmatory ground water sampling were found to meet the applicable site conditions standards are presented on Figure 14, indicating that the original ground water impacts identified had been removed. 4.8 Reasons for Discharge of Contaminant The discharge of Contaminants of Concern at the property in the soil occurred as a result of the activities at the property which included the maintenance and repair of automobiles. Terraprobe Page No 18 Phase Two Environmental Site Assessment 17645 Yonge Street, Newmarket, Ontario 4.9 Nov 20, 2014. Revised Mar 6, 2015 11-10-5203 Migration of Contaminant Contaminants of Concern were identified in the earth fill, native soils and ground water. Based on the direction of ground water flow ground water wells were placed down gradient of known ground water impacts and were delineated. The migration of impacts was limited by the tight glacial till soils where the impacts were identified. 4.10 Climatic or Meteorological Influences on Migration The Property was covered by a completely by a hard cap (asphalt and buildings during the time where contaminants were present). There is no erosion occurring on the Property and no significant seasonal variation in the water table. Climatic or meteorological influence appear to have had little to no influence on migration of contamination on the Property 4.11 Soil Vapour Intrusion into Buildings No volatile Contaminants of Concern have been identified on the Property in the soil and ground water during the investigation. As such there is no possibility for soil vapour intrusion of contaminants into future buildings. No buildings currently exist on the Property, therefore there is no possible of vapour intrusion. 4.12 Relevant Construction Features of Buildings No buildings were present on the Property. 4.13 Building HVAC No HVAC systems were present and no volatile Contaminants of Concern have been identified on the Property. Therefore, it is not possible building HVAC to affect the distribution and transport of Contaminants of Concern. 4.14 Subsurface Structures and Utilities Underground utilities are present on the Property. Based upon this, it is possible that any potentially contaminated ground water could migrate horizontally along the utilities onto or off the Property. However in the area where the soils impacts were identified, they were removed. There is no further source of impact on the Property.
