Quebec’s legal warranty is a unique protection in North America. It requires the seller to guarantee that the property sold is free of hidden defects. Yet, more and more sales are done “at the buyer’s risk,” a clause that can prove extremely costly. Here’s everything you need to know to make an informed decision.
1. What is the legal warranty?
The legal warranty is established under articles 1726 to 1731 of Quebec’s Civil Code (CCQ). It has two components: the warranty of quality (the property is free of hidden defects that make it unfit for use) and the warranty of ownership (the seller has the right to sell and the property is free of undisclosed charges).
This protection applies automatically to every real estate transaction in Quebec unless a specific clause excludes it. The seller is liable even if they were unaware of the defect. This is fundamentally different from the rest of Canada, where the “caveat emptor” (buyer beware) principle applies.
In practical terms, if you discover a foundation problem six months after purchase, the seller must compensate you for repairs. For a detailed understanding of hidden defect criteria, read our complete guide to hidden defects in Quebec.
2. Buying “at the buyer’s risk”
When a sale is made without the legal warranty, the buyer waives protection against hidden defects. This clause, known as “at the buyer’s risk and peril,” transfers all risk to the buyer. According to OACIQ guidelines in 2026, this clause is common in the following situations:
Estate sales
Heirs often don’t know the true condition of the property and refuse to guarantee it.
Bank repossessions
Financial institutions sell as-is, with no knowledge of the building’s history.
Property flips
Some sellers try to avoid liability after quick renovations.
Older properties
Sellers of very old homes (50+ years) seek to limit their responsibility.
Without the legal warranty, your only recourse is proving fraud (dol) by the seller: you must demonstrate they knew about the defect and deliberately concealed it. This proof is extremely difficult to establish in court.
3. Cost comparison: with vs without warranty
Consider a realistic scenario: you buy a property and discover a major foundation defect costing $45,000 to repair. Let’s compare both situations.
Scenario: foundation defect — $45,000
With legal warranty
• Foundation repair: $45,000
• Recourse against seller: demand letter (~$500)
• Amount recovered: $45,000 (full compensation)
→ Net cost to buyer: ~$500
Without legal warranty (“at buyer’s risk”)
• Foundation repair: $45,000
• Legal fees to prove fraud: $15,000–$25,000
• Probability of success: low (~30%)
→ Net cost to buyer: $45,000 + $15,000–$25,000 = $60,000–$70,000
Financial exposure difference: between $59,500 and $69,500. The legal warranty protects you against nearly all financial risk.
4. When is the warranty excluded?
Article 1733 of the CCQ allows the legal warranty to be excluded or limited by a contractual clause. However, this exclusion does not protect a seller who knew about the defect (art. 1733 para. 2). Three levels of warranty exist in practice:
| Level | Protection | Risk |
|---|---|---|
| Full legal warranty | Hidden defects + ownership rights | Minimal |
| Reduced warranty | Negotiated limits (e.g., roof excluded) | Moderate |
| No warranty | None (except proven fraud) | High |
OACIQ recommends that all buyers prioritize properties sold with full legal warranty. If you’re considering a purchase without warranty, a thorough pre-purchase inspection is absolutely essential.
5. How to protect yourself before buying
Whether or not the sale includes the legal warranty, here are the essential steps to minimize your risk:
Check the warranty clause in the promise to purchase before signing. Request the OACIQ Seller’s Declarations (DV) form. Get a pre-purchase inspection by a certified inspector with thermal imaging. Request specific expert assessments if the building is over 30 years old (foundation, plumbing, roof). Check the land registry for sale and mortgage history. Hire an OACIQ-certified real estate broker who understands the legal warranty’s particularities.
If the seller refuses the legal warranty, negotiate a price reduction proportional to the risk. Generally, a 5–10% discount is justified to compensate for the absence of warranty on a property over 25 years old.
Protect your investment with a broker who understands the legal warranty.
