KEY FINDINGS

  • Canadian home sellers must generally disclose known material latent defects.
  • Patent defects are visible issues that buyers are expected to identify during an inspection.
  • Latent defects are hidden problems that may require disclosure if they affect a home's safety, value, or habitability.
  • Common examples include concealed mould, hidden water damage, structural damage, and foundation issues.
  • Sellers who knowingly conceal material defects may face legal action after a sale closes.
  • Death and other property stigmas usually do not require disclosure unless a buyer specifically requests information.

In Canada, sellers are usually required to disclose known material latent defects when selling their home. Hidden problems that make a property dangerous, uninhabitable, or significantly affect its value or intended use are considered necessary disclosures.

While real estate laws vary slightly between provinces, the core principle is similar across Canada: sellers cannot knowingly hide serious defects from buyers.

"The law is fairly uniform across Canada," says Mark Weisleder, lawyer, author, speaker, and senior partner at Real Estate Lawyers.ca LLP. "It is still very much 'buyer beware'."

What is the difference between a patent defect and a latent defect?

"A patent defect means a defect that is visible during a regular home inspection. It can include cracks in walls, windows, or floors," says Weisleder.

A latent defect is hidden and cannot be discovered through a reasonable inspection. Examples may include mould behind walls, concealed water damage, or structural issues that are not visible during an inspection.

One of the most important concepts in Canadian real estate law is understanding the difference between patent defects and latent defects.

This distinction reflects the legal principle of buyer beware (caveat emptor, meaning the buyer is responsible for identifying defects before purchase). Buyers are expected to conduct their own due diligence, including arranging a home inspection whenever possible. 

What is a material latent defect?

"Material latent defect means it renders the home uninhabitable or dangerous for a buyer. This can include a foundation problem or a major flood that was not repaired," says Weisleder.

Not every hidden problem requires disclosure. A material latent defect is one that is serious enough that it could:

  • Make the home unsafe
  • Make it unfit for habitation
  • Significantly affect its intended use
  • Require expensive repairs that could influence a buyer's decision

According to Carolin MacDonald, compliance manager at Nova Scotia Real Estate Commission (NSREC), a material latent defect cannot be discovered through a reasonable inspection. To qualify, it must also make the property dangerous or unfit for habitation, require significant expense to remedy, or be something that can reasonably affect a buyer's decision.

In British Columbia, the BC Financial Services Authority (BCFSA)’s definition also extends to outstanding municipal remediation notices and unpermitted alterations.

What defects must sellers disclose?  

According to experts like MacDonald, sellers must disclose known material latent defects. The key factor is that the seller must know about the issue. Common examples MacDonald suggests include:

DefectRequires disclosure?
Major foundation problemsYes
Hidden water damage or chronic leaksYes
Concealed mouldYes
Structural damageYes
High radon levelsOften, if known and material
Hidden asbestos or environmental hazardsOften, depending on severity
Major pest infestationsIf hidden and material
Outstanding municipal work ordersYes
Unpermitted renovations affecting safety or valueOften yes
Cosmetic wear and tearNo
Visible cracked drywallUsually no (patent defect)

"Sellers and their agents, if they know about it, must disclose any material latent defect that they are aware of," says Weisleder.

Sellers commonly provide information about a property's condition through a property disclosure statement, although requirements vary by province. According to BCFSA, real estate licensees also have their own obligation to disclose known material latent defects before a legal contract is signed.

NSREC’s MacDonald says under Nova Scotia's by-laws, the provincial Commission expects licensees to disclose known material latent defects as soon as they're aware of them.  

"A licensee who is providing real estate services to a client who is disposing of real estate must provide written disclosure to all other parties to the trade, promptly and before any agreement for the acquisition or disposition of the real estate is entered into, any material latent defect in the real estate that is known to the licensee."

What if the defect was repaired?

A previous issue does not necessarily need to be disclosed if it has been fully repaired, and no ongoing problem remains.

"If the defect was properly repaired, such as a flood or foundation problem, and no problem persisted, then no disclosure is required," says legal expert Weisleder.

However, sellers should keep documentation showing repairs were completed professionally in case questions arise during the sale. Invoices, permits, and inspection reports can help demonstrate that the issue was properly addressed.

Are disclosure rules when selling a home different across Canada?

Although each province regulates real estate slightly differently, underlying legal principles are broadly similar. Weisleder says the law is "fairly uniform across Canada”.

Some provinces have additional regulatory requirements for real estate professionals. For example: 

ProvinceAdditional disclosure requirements
British ColumbiaLicensees must provide written disclosure of known material latent defects before a contract is signed.
Nova ScotiaCommission bylaws require licensees to promptly disclose known material latent defects in writing before an agreement is entered into.
QuebecCivil Code provides strong protections for buyers regarding hidden or latent defects, although legal framework differs from that of common law provinces.

MacDonald says that while she can't speak to other provinces, Nova Scotia's requirements are based on common law principles.  

"Our understanding of consumer disclosure requirements is based on the common law, whereby sellers are required to disclose material latent defects to buyers, and where patent defects do not carry mandatory requirements."

Because disclosure obligations can depend on specific circumstances of a transaction, sellers who are unsure what they must disclose should seek legal advice.

Do sellers have to disclose if someone died in the home?

Deaths, suicides, murders, or other events that may create a psychological stigma usually do not have to be disclosed proactively in most Canadian jurisdictions.

"In general, no psychological stigma needs to be disclosed,” says Weisleder citing situations involving murder, suicide, natural death, shooting, or a crazy neighbour.

The BCFSA similarly states that sellers are not required to volunteer information about stigmas, such as deaths on a property, unless specifically asked.  

MacDonald says Nova Scotia follows a similar approach.  

"In Nova Scotia, we do not require licensees to disclose stigmas; however, if asked by the buyer, they are to answer truthfully."

What if the buyer explicitly asks about property stigmas?

While sellers of homes generally don't have to volunteer information about stigmas, they cannot misrepresent facts.

"If a buyer asks about any of these issues, the seller and the agent must answer truthfully," says Weisleder.

He notes this is one reason some purchase agreements contain representations stating there were no murders, suicides, or natural deaths on the property. If a seller signs such a clause, it must be accurate. 

Can a buyer sue if a seller fails to disclose something?

If a seller knowingly conceals a material latent defect, a buyer may have legal remedies after closing.

"If the seller knows about a major hidden defect and does not disclose, they can be sued for the repair costs after closing. But a buyer must be able to prove a seller knew [of the defect]," says Weisleder.

According to the BCFSA, what a buyer can actually recover from suing the seller for undisclosed defects depends on "the facts, jurisdiction, and whether the non-disclosure was negligent, intentional, or fraudulent". Remedies as a result of a successful lawsuit against non-disclosure can range from compensation for repair costs and a reduction in the purchase price to damages. In rare cases, non-disclosure of material and known defects could result in rescission of the home sale entirely. 

Does waiving a home inspection cost you legal protection as a buyer?

Skipping a home inspection can limit your legal options as a buyer if problems surface after closing on your home purchase. Buyers are still expected to exercise reasonable diligence, even where seller disclosure obligations exist.

"If you buy without a home inspection being done, you will likely have to accept any defect that a home inspector could have found," says Weisleder.

That's why home inspections remain one of the most important protections available to buyers, particularly in competitive housing markets. 

What are tips sellers can use to reduce legal risk?

If you're preparing to sell your home:

  • Disclose any known material latent defects honestly
  • Keep records of major repairs and renovations
  • Retain permits and inspection reports where applicable
  • Answer buyer questions truthfully
  • Consult your lawyer if you're unsure whether something should be disclosed
  • Work closely with your real estate agent, who may have separate regulatory disclosure obligations

Ultimately, clear communication and proper disclosure can help protect both parties. As the BCFSA notes, "where a buyer has concerns about the accuracy or completeness of information provided by the seller, the buyer should consider obtaining independent legal advice to better understand their rights and options."
