Key Disclosure

May 22, 2025


What is Key Disclosure?

Key disclosure refers to the seller’s obligation to disclose material facts or known defects about a property that could affect a buyer’s decision to purchase.

Why Key Disclosure Matters in Real Estate

In Canadian real estate, sellers are required to disclose **latent defects**—issues not visible through ordinary inspection that pose health, safety, or legal risks.


Examples of key disclosures include:
  • Previous flooding or foundation issues
  • Illegal renovations or permits not obtained
  • Mold, asbestos, or environmental hazards


Failure to disclose can lead to legal action for misrepresentation or breach of contract. Some provinces use standard Seller Property Information Statements (SPIS) to formalize disclosure.


Understanding key disclosure protects buyers from hidden problems and holds sellers accountable for property condition transparency.

Example of Key Disclosure in Action

A seller discloses a history of basement flooding on the SPIS form. The buyer proceeds with caution and includes a repair clause in the offer.

Key Takeaways

  • Sellers must disclose material issues.
  • Includes hidden defects and legal risks.
  • Protects buyers from surprise problems.
  • May involve formal disclosure forms.
  • Legal remedies exist for nondisclosure.

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.
