4 Factual Data Report GeoPro Project: G17 Toronto Water and Transportation Services Program Geotechnical Investigation Watermain Replacement on Westmore Drive, City of Toronto, Ontario 1 INTRODUCTION GeoPro Consulting Limited (GeoPro) was retained by The Municipal Infrastructure Group Limited (the Client) to conduct a geotechnical investigation for the Toronto Water and Transportation Services Program - proposed watermain replacement on Westmore Drive from Finch Avenue West to Albion Road, City of Toronto, Ontario. The purpose of this geotechnical investigation was to obtain information on the existing subsurface conditions by means of a limited number of boreholes, in-situ tests and laboratory tests of soil samples. The geo-environmental (chemical) aspects of the subsurface conditions, including the consequences of possible surface and/or subsurface contamination resulting from previous activities or uses of the site and/or resulting from the introduction onto the site of materials from off-site sources were not investigated and were beyond the scope of this assignment. However, limited chemical testing was carried out on selected soil samples. The site investigation follows generally accepted practice for geotechnical consultants in Ontario. Laboratory testing follows ASTM or CSA Standards or modifications of these standards that have become standard practice in Ontario. This report has been prepared for the Client only. Third party use of this report without GeoPro s consent is prohibited. The limitations to the report presented above form an integral part of the report and they must be considered in conjunction with this report. 2 INVESTIGATION PROCEDURE Field work for the geotechnical investigation was carried out on July 26, August 10, 13 and 27, 2018 during which time ten (10) boreholes (Boreholes BH17-1 to BH17-10) were advanced to depths ranging from about 2.9 m to 3.5 m below the existing ground surface. In addition, the pavement was cored at thirteen (13) locations (Coreholes CH17-1 to CH17-13) using a core drill in order to obtain samples of the existing asphalt concrete for asbestos analysis testing. The borehole and corehole locations are shown on attached Drawings. A proposed borehole location plan prepared by GeoPro was provided to Client for review prior to the filed investigation work. The approved borehole locations were staked in the field by GeoPro; the borehole locations in the field were adjusted according to the drill rig accessibility and the underground utility conditions. The field work for this investigation was monitored by a member of our engineering staff who logged the boreholes and cared for the recovered samples. The boreholes were advanced using a continuous flight auger drilling equipment supplied by a drilling specialist subcontracted to GeoPro. Samples were retrieved with a 51 mm (2 inches) O.D. split-barrel (split spoon) sampler driven with a hammer weighing 624 N and dropping 760 mm (30 inches) in accordance with the Standard Penetration Test (SPT) method.

5 Factual Data Report GeoPro Project: G17 Toronto Water and Transportation Services Program Geotechnical Investigation Watermain Replacement on Westmore Drive, City of Toronto, Ontario required to drive the sampler 300 mm (12 inches) depth into the undisturbed soil (SPT N values) gives an indication of the compactness condition or consistency of the sampled soil materials. Groundwater condition observations were made in the boreholes during drilling and upon completion of drilling. The Boreholes were backfilled and sealed upon completion of drilling. An monitoring well (51 mm in diameter) was installed in each of the selected borehole(s) to measure the groundwater table and to facilitate the in-situ hydrogeological testing. All soil samples obtained during this investigation were brought to our laboratory for further examination. These soil samples will be stored for a period of three (3) months after the day of issuing draft report, after which time they will be discarded unless we are advised otherwise in writing. Geotechnical classification testing (including water content, grain size distribution and Atterberg Limits, when applicable) was carried out on selected soil samples. The laboratory test results are attached to Figures. It should be noted the elevations at the as-drilled borehole locations were not available at the time of preparing the report. The borehole and corehole locations plotted on the Borehole/Corehole Location Plan were based on the measurement of the site features and should be considered to be approximate. 3 SUBSURFACE CONDITIONS 3.1 Subsurface Conditions Notes on sample descriptions are presented in Enclosure 1A. Explanations of terms used in the borehole logs are presented in Enclosure 1B. The subsurface conditions in the boreholes are presented in the individual borehole logs. Detailed descriptions of the major soil strata encountered in the boreholes drilled at the site are provided as follows. Pavement Structure A flexible pavement structure was observed. The range and average thicknesses of pavement structure are summarized in the following table: Asphalt Concrete in Boreholes and Coreholes Range (Average) (230) Pavement Structure (mm) Granular Base/Subbase Range (Average) (340) Unit 57, 40 Vogell Road, Richmond Hill, ON Tel: Fax: office@geoproconsulting.ca

Each core was split into two portions between surface layer and binder layer. These asphalt samples were submitted to Eurofins Environmental Laboratories ( Eurofins ) in Ottawa, Ontario to determine if asbestos fibres are present in the existing asphalt concrete. To analyze for asbestos in asphalt samples, Eurofins uses mineralogical characterisation by polarised light microscopy and dispersion staining colours in accordance with EPA 600/R- 93/116 method. Based on the analytical results, no asbestos fibres were identified in the asphalt concrete core samples. A summary of asphalt concrete cores and asbestos testing results is attached in Appendix A, and a copy of asbestos analysis results with the Laboratory Certificates of Analysis are provided in Appendix B.

17 ENCLOSURES

18 Enclosure 1A: Notes on Sample Descriptions 1. Each soil stratum is described according to the Modified Unified Soil Classification System. The compactness condition of cohesionless soils (SPT) and the consistency of cohesive soils (undrained shear strength) are defined according to Canadian Foundation Engineering Manual, 4 th Edition. Different soil classification systems may be used by others. Please note that a description of the soil stratums is based on visual and tactile examination of the samples augmented with field and laboratory test results, such as a grain size analysis and/or Atterberg Limits testing. Visual classification is not sufficiently accurate to provide exact grain sizing or precise differentiation between size classification systems. 2. Fill: Where fill is designated on the borehole log it is defined as indicated by the sample recovered during the boring process. The reader is cautioned that fills are heterogeneous in nature and variable in density or degree of compaction. The borehole description may therefore not be applicable as a general description of site fill materials. All fills should be expected to contain obstruction such as wood, large concrete pieces or subsurface basements, floors, tanks, etc., none of these may have been encountered in the boreholes. Since boreholes cannot accurately define the contents of the fill, test pits are recommended to provide supplementary information. Despite the use of test pits, the heterogeneous nature of fill will leave some ambiguity as to the exact composition of the fill. Most fills contain pockets, seams, or layers of organically contaminated soil. This organic material can result in the generation of methane gas and/or significant ongoing and future settlements. Fill at this site may have been monitored for the presence of methane gas and, if so, the results are given on the borehole logs. The monitoring process does not indicate the volume of gas that can be potentially generated nor does it pinpoint the source of the gas. These readings are to advise of the presence of gas only, and a detailed study is recommended for sites where any explosive gas/methane is detected. Some fill material may be contaminated by toxic/hazardous waste that renders it unacceptable for deposition in any but designated land fill sites; unless specifically stated the fill on this site has not been tested for contaminants that may be considered toxic or hazardous. This testing and a potential hazard study can be undertaken if requested. In most residential/commercial areas undergoing reconstruction, buried oil tanks are common and are generally not detected in a conventional preliminary geotechnical site investigation. 3. Till: The term till on the borehole logs indicates that the material originates from a geological process associated with glaciation. Because of this geological process the till must be considered heterogeneous in composition and as such may contain pockets and/or seams of material such as sand, gravel, silt or clay. Till often contains cobbles (60 to 200 mm) or boulders (over 200 mm). Contractors may therefore encounter cobbles and boulders during excavation, even if they are not indicated by the borings. It should be appreciated that normal sampling equipment cannot differentiate the size or type of any obstruction. Because of the horizontal and vertical variability of till, the sample description may be applicable to a very limited zone; caution is therefore essential when dealing with sensitive excavations or dewatering programs in till materials.

Number : Ottawa Project Our Project : Your Project : G17 Date Received : September 7 th 2018 Date Analysed: September 17 th 2018 MINERALOGICAL CHARACTERISATION BY POLARISED LIGHT MICROSCOPY AND DISPERSION STAINING COLOURS EPA METHOD EPA/600/R-93/116 Twenty-six (26) samples were submitted for analysis by polarised light microscopy and dispersion staining colours. The samples were prepared and observed using the following procedure: A fragment of each sample was isolated. If needed in order to extract the fibres, the samples are submitted to light mechanical crushing. The particles and fibres produced are transferred to a glass slide, covered with a cover glass and immersed in the appropriate refractive index liquids in order to observe the dispersion staining colours. The orthoscopic and conoscopic optical properties of the samples are also used if they permit further characterisation of the samples. The results are summarised as follows: CH17-1 Surface Black and grey material Asbestos fibres None detected Naturally occurring organic fibres (cellulose) < 1 % Angular particles, fragments and other > 95 % CH17-1 Binder Black and grey material Asbestos fibres None detected Naturally occurring organic fibres (cellulose) < 1 % Angular particles, fragments and other > 95 % CH17-2 Surface Brown and grey material Asbestos fibres None detected Naturally occurring organic fibres (cellulose) < 1 % Angular particles, fragments and other > 95 % CH17-2 Binder Brown and grey material Asbestos fibres None detected Naturally occurring organic fibres (cellulose) < 1 % Angular particles, fragments and other > 95 % CH17-3 Surface Grey and black material Asbestos fibres None detected Naturally occurring organic fibres (cellulose) < 1 % Angular particles, fragments and other > 95 % 121 Boulevard Hymus T Pointe-Claire F Québec, Canada H9R 1E _PLM_Eurofins-Ottawa page 1 of 5

Therefore negative PLM results cannot be guaranteed. The analytical method is semi-quantitative. The applicability of this method varies between <1 % and 100 % (v/v). Eurofins suggests that certain samples reported as «None detected», «traces» or «<1%» be analysed by TEM. The present certificate relates only to the samples analysed. The presence certificate may not be reproduced, except in full, without written approval by Eurofins. The laboratory is not responsible for the accuracy of results when requested to physically separate and analyse layered samples. The laboratory is not responsible for the representativeness of the samples submitted for analysis. Samples will be kept for a period of 60 days or according to the written request of the client.

107 LIMITATIONS TO THE REPORT The subsurface conditions given in this report are based on information obtained at the limited number of the test hole and test pit locations. The boundaries between the various strata as shown on the borehole logs are based on non-continuous sampling and represent an inferred transition between the various strata and their lateral continuation rather than a precise plane of geological change. Subsurface and groundwater conditions between and beyond the test holes and test pits may differ significantly from those encountered at the test hole and test pit locations. The benchmark and elevations used in this report are primarily to establish relative elevation differences between the test hole and test pit locations and should not be used for other purposes, such as grading, excavating, planning, development, etc. It should be noted that the results of the designated substance and chemical analysis refer only to the sample analyzed which was obtained from specific sampling location and sampling depth, and the presence of designated substance and soil chemistry may vary between and beyond the location and depth of the sample taken. Please note that the level of chemical testing outlined herein is meant to provide a broad indication of soil quality based on the limited soil samples tested. The analytical results contained in this report should not be considered a warranty with respect to the soil quality or the use of the soil for any specific purpose or the acceptability of the soils for any excess soil receiving sites. The report reflects our best judgment based on the information available to GeoPro Consulting Limited at the time of preparation. Unless otherwise agreed in writing by GeoPro Consulting Limited, it shall not be used to express or imply warranty as to any other purposes. No portion of this report shall be used as a separate entity; it is written to be read in its entirety. The site investigation follows generally accepted practice for geotechnical and geo-environmental consultants in Ontario. Laboratory testing follows ASTM or CSA Standards or modifications of these standards that have become standard practice in Ontario. Depending on the construction methods selected, the number of test holes and test pits may not be sufficient to determine all the factors that may affect construction activities, methods and costs. Such as, the thickness of surficial topsoil or fill layers may vary significantly and unpredictably; the amount of the cobbles and boulders may vary significantly than what described in the report; unexpected water bearing zones/layers with various thickness and extent may be encountered in the fill and native soils. The contractors bidding on this project or undertaking the construction should, therefore, make their own interpretation of the factual information presented and make their own conclusions as to how the subsurface conditions may affect their work and determine the proper construction methods. This report is intended solely for the Client named. Any use which a third party makes of this report, or any reliance on or decisions to be made based on it, are the responsibility of such third parties. GeoPro Consulting Limited accepts no responsibility for damages, if any, suffered by any third party as a result of decisions made or actions based on this report. We accept no responsibility for any decisions made or actions taken as a result of this report unless we are specifically advised of and participate in such action, in which case our responsibility will be as agreed to at that time.
