Latent Defect

May 30, 2025


What is a Latent Defect?

A latent defect is a hidden flaw in a property that is not visible during a typical inspection and may affect its safety, use, or value.

Why Do Latent Defects Matter in Real Estate?

In Canadian real estate, sellers are legally obligated to disclose known latent defects that make the home unsafe or unfit for habitation. These cannot be easily detected by the buyer or inspector.



Examples of latent defects include:
  • Mold behind walls
  • Foundation cracks or structural instability
  • Undisclosed water damage or past flooding



If the seller fails to disclose a known latent defect, they may face legal consequences. Buyers should include inspection conditions and seek professional advice for potential red flags.



Understanding latent defects protects buyers from surprise repairs and helps sellers meet legal disclosure obligations.

Example of a Latent Defect

After moving in, the buyer discovered black mold behind the drywall. The seller had not disclosed it, resulting in a legal claim for latent defect.

Key Takeaways

  • Hidden flaws not visible in standard inspection.
  • Must be disclosed if known.
  • Can affect safety or habitability.
  • May lead to legal action if concealed.
  • Strong reason for buyer due diligence.

The milestone follows a successful pre-sales launch for the community's first two buildings, Atlin and Bute, which sold enough homes to green light construction.

A $90B Question: Can Alto Reshape Real Estate Between Toronto And Quebec City?

Alto

Alto and its partner Cadence — the corporations behind Canada’s first proposed high-speed rail network — announced in late March that they would be moving forward with the next phase of the project’s environmental study, including requesting access to private properties to determine the best pathway for track laying.

The $60-$90 billion project, which was first announced last February, will span roughly 1,000 km between Toronto, Peterborough, Ottawa, Montreal, Laval, Trois-Rivières, and Quebec City. Travelling at speeds of 300 km/h or more, the electric rail network will reduce the travel time between Toronto and Montreal to just three hours.

CreateTO, the City of Toronto’s dedicated housing agency, is forging ahead with a mixed-income housing community at 805 Wellington Street West — the location of the Strachan House building in Liberty Village.

Strachan House was built in 1888 and served an 80-year stint as a major lumber planing mill under John B. Smith & Sons. In 1989, the property was converted into supportive housing, operated by the Homes First Society, but residents were displaced in early-2022 as the City toyed with redevelopment plans.

GTA Home Sales Rise In March As Prices Continue To Fall

Greater Toronto Area resale housing market conditions tightened in March 2026, with sales climbing year-over-year even as selling prices declined — a dynamic that may be offering some buyers a narrowing window of affordability heading into spring.

GTA REALTORS® reported 5,039 home sales through TRREB's MLS® System last month, a 1.7% increase compared to March 2025. At the same time, new listings fell sharply — down 16.7% year-over-year to 14,442 — meaning more buyers are competing for fewer homes than this time last year.

Toronto City Council approved zoning for over a dozen housing developments at its March 2026 session (held last week), and the green-lit slate includes four projects that will be rolled out under the new Toronto Builds policy framework, like the highly anticipated revitalization of Swansea Mews.

These projects couldn’t come soon enough. According to Toronto’s housing data hub, 87,551 new homes have been created between January 1, 2022, and January 31, 2026, representing just over 30% of the City’s provincial housing target of 285,000 new homes by 2030.
