July 27, 2025


What is a Geotechnical Survey?

A geotechnical survey is a field investigation and analysis of soil, rock, groundwater, and other subsurface conditions on a site to assess its suitability for construction.

Why Geotechnical Surveys Matter in Real Estate

In Canadian real estate development and construction, geotechnical surveys identify potential risks and inform the design of foundations, retaining walls, and drainage systems.



Key elements:
  • Soil bearing capacity and composition
  • Groundwater table levels
  • Slope stability and erosion risks
  • Presence of contaminants or problematic soils



A geotechnical survey is often required before issuing building permits for new construction or significant redevelopments.

Example of a Geotechnical Survey in Action

The developer commissioned a geotechnical survey to ensure the soil could support the planned high-rise building.

Key Takeaways

  • Evaluates subsurface conditions before construction
  • Informs foundation and drainage design
  • Helps identify environmental or soil risks
  • Required for many building projects
  • Reduces structural and safety issues

Canada Mortgage and Housing Corporation (CMHC) released new housing starts data this week, and, on the surface, there was something of a rosy tone. The government agency reported that the seasonally-adjusted annual rate (SAAR) of housing starts edged up 4% in July to 294,085 units, marking the highest level of starts since September 2022.

That would give you the impression that starts, defined as the moment the foundation on a new build has been poured, are on a good trajectory, however, it’s more indicative of development intention from the past. As stated by CMHC’s Deputy Chief Economist Tania Bourassa-Ochoa in a press release from Monday, the “persistently elevated national results are reflective of investment decisions made months or even years ago, highlighting the influence of previous market conditions and builder sentiment on current construction trends.”

A report released Wednesday finds that the GTA is on track to amass a roughly 235,000-unit deficit in purpose-built rental (PBR) housing supply over the next 10 years, made up of the current and projected shortfall in units. Using comparative pro forma analysis, the report also shows how far targeted policy changes can go towards making projects more viable moving forward.

The report was assembled by the Building Industry and Land Development Association (BILD) in conjunction with real estate consulting firm Urbanation and cost consulting company Finnegan Marshall, and it shares sobering insights into current PBR housing needs in the GTA, how project feasibility has changed since 2022, and policy changes they say need to be implemented by all three levels of government in order to meet housing needs over the next decade.

A 12-storey mid-rise proposal slated for 635 Sheppard Avenue East and 1 Greenbriar Road in the North York district of Toronto has jumped in height to 30 storeys, according to revised plans from AC Development. The more-than-double increase reflects the fact that “the policy framework and development trends for the surrounding area have changed,” according to the planning report that went to the City.

Official plan and zoning bylaw amendment applications for the initial 12-storey development at southeast corner of Sheppard Avenue East and Greenbriar Road were adopted by City Council in October 2023, and at the time, the proposal called for 145 units, as well as around 115,510 sq. ft of total gross floor area (GFA), including around 4,343 sq. ft to be dedicated to non-residential.
