Site Remediation

June 23, 2025


What is Site Remediation?

Site remediation is the process of cleaning up contaminated land to meet environmental standards and make the property safe for use or redevelopment.

Why Site Remediation Matters in Real Estate

In Canadian real estate, site remediation is often required after an environmental assessment identifies soil or groundwater contamination, especially for commercial or industrial properties.



Remediation steps may include:
  • Excavation and removal of contaminated soil
  • Groundwater treatment
  • Installation of containment barriers
  • Ongoing monitoring and reporting



Municipalities and environmental regulators may require a Record of Site Condition (RSC) before development can proceed.



Understanding site remediation is critical for developers, lenders, and buyers investing in infill, brownfield, or legacy-use properties.

Example of Site Remediation in Action

The developer hires an environmental firm to conduct site remediation on a former gas station lot before applying for building permits.

Key Takeaways

  • Cleans up contaminated land for safe use
  • Required for many commercial redevelopments
  • Triggered by environmental assessments
  • Involves removal, treatment, or containment
  • May impact permitting and land value

Elysium Proposes 41- And 39-Storey Rental Next To Keele Station
26-36 Mountview Avenue and 21-29 Oakmount Road/Teeple Architects

A snazzy new two-tower, high-rise development is headed for the High Park North neighbourhood of Toronto that could deliver over 870 new rental units within walking distance of Keele Station. The proposal was submitted by Elysium Investments in early-September and comprises an Official Plan and Zoning By-law Amendment application for a 41- and 39-storey building with a shared six-storey podium.

If approved, the development would replace 11 single-detached homes located just north of High Park. Addressed as 26-36 Mountview Avenue and 21-29 Oakmount Road, the proposed site sits just northwest of the Bloor Street West and Keele Street intersection. The site is well-serviced by public transit, with Keele Station on the TTC's Line 2 directly adjacent to the proposed building, providing connections to Line 1, GO Transit, and the UP Express.

Ontario’s Trust Test: Lessons From The iPro Realty Collapse

Ontario’s Trust Test: Lessons From The iPro Realty Collapse
iPro Reality branch in Brampton, Ontario/Google Maps

This article was written and submitted by former CEO of the Ontario Real Estate Association (OREA) Tim Hudak and long-time senior Ontario civil servant Frank Denton. Hudak is currently partner at Counsel Public Affairs Inc., and Denton is a senior advisor.

The collapse of iPro Realty, one of Ontario’s largest independent brokerages, has left at least an $8-million shortfall in its trust accounts and put the regulator, the Real Estate Council of Ontario (RECO), under an intense spotlight. For buyers, sellers, and real estate agents, the scandal raises urgent questions about whether their deposits are safe. When suspicion falls on an arm’s-length regulator with delegated authority from government, pressure on the Minister to act is swift. At its core, this is not just a regulatory challenge but a trust challenge — and once public trust is broken, other delegated authorities in Ontario may soon be under the same spotlight.

Despite the fact that Toronto’s unhoused population has more than doubled since 2021, the City is set to receive a fraction of the Canada-Ontario Housing Benefit (COHB) funding in its sixth year that it did in both its fourth- and fifth-year allocations.

Toronto Mayor Olivia Chow wrote in a letter that went to the Executive Committee on Monday that the Province allocated $38 million to Toronto from the COHB between April 2024 and March 2025, and $19.75 million from April 2025 to March 2026 — but between April 2026 and March 2027, the City will receive only $7.95 million, representing an almost 60% decrease year over year.
