CanadaCanada's Sale of Goods Act: the warranty you already have before you buy one
Every page in this Library's Canada section so far has covered a warranty or service contract you actually buy. This one covers a legal protection that already exists the moment you buy almost anything from a business, whether you ever purchase a home warranty or vehicle service contract or not — because a purchased contract sits on top of this baseline, not in place of it.
What the Act actually implies into a sale
Every common-law province and territory has its own Sale of Goods Act, each closely modelled on the same 19th-century template and worded almost identically province to province. Ontario's version is typical: section 14 implies a condition that goods sold by description will actually correspond with that description, and section 15 implies a condition that goods bought by description from a seller who deals in goods of that description will be of merchantable quality — reasonably fit for their ordinary purpose — plus a separate implied condition of fitness where the buyer made a particular purpose known and relied on the seller's judgment. None of this requires a written warranty, a purchased service contract, or even a request from the buyer; it attaches automatically to the sale itself.
A consumer sale generally can't contract these away
On its own, the Sale of Goods Act would let a seller disclaim all of this in the fine print. Every province's consumer protection statute closes that door for a consumer sale specifically: Ontario's Consumer Protection Act, 2002, for example, deems the Sale of Goods Act's implied conditions to apply to a consumer agreement and states directly that any term — inside the agreement or not — purporting to negate or vary one of them, or to limit the seller's liability for breaching one, is void. A term like that doesn't even need to be struck out by a court to lose its force; the statute already treats it as if it were never there. This is the general-law reason an "as-is" clause on a purchase from a business rarely does what it appears to do for a private buyer — it can still narrow what a seller has to disclose, but it doesn't erase the underlying statutory conditions the way sellers sometimes imply it does.
The real limits: who's selling, and when the defect existed
Two limits matter more in practice than most buyers realize. First, the merchantable-quality and fitness conditions above only attach where the seller "deals in goods of that description" — a commercial seller, not a private individual selling their own used car or appliance directly to another consumer; a private sale generally falls outside the Act's implied-quality protections entirely, which is exactly why a dealer sale and a private sale of the same used vehicle can carry very different baseline protection. Second, the implied conditions speak to the goods' condition at the time of sale, not to ordinary wear or a failure that develops later — which is precisely the gap a purchased home warranty or vehicle service contract is designed to fill, and precisely why the two aren't substitutes for each other.
Quebec runs on a different law entirely
The Sale of Goods Act doesn't apply in Quebec, a civil-law jurisdiction: the equivalent baseline comes from the Civil Code of Québec's own legal warranty of quality (arts. 1726–1731), which a seller likewise can't simply waive against a consumer buyer under the Consumer Protection Act. Quebec has since layered a second, newer protection on top of that general warranty — the statutory "legal warranty of good working order" for defined categories of goods, and the mandatory pre-sale extended-warranty disclosure, both created by Bill 29 and covered in depth on our Quebec extended warranty disclosure page. The two protections are separate and shouldn't be conflated: the Civil Code's general legal warranty of quality is Quebec's rough equivalent to the rest of Canada's Sale of Goods Act baseline; the newer good-working-order warranty and disclosure rule is a distinct, more recent addition on top of it.
Why this matters before you buy a warranty, not instead of one
None of this is a reason to skip a home warranty or vehicle service contract — the implied-condition baseline above only reaches a defect that existed at the time of sale, from a commercial seller, and says nothing about a covered system or component that fails later from ordinary use. What it does mean is that a seller who tries to wave away a problem discovered shortly after a purchase by pointing at an "as-is" clause or a "no warranty" sign is very often wrong about what that actually does under a province's own consumer protection law — worth knowing before assuming a purchased service contract is the only protection in play. It's also the reason point 5 of our standard — how a provider discloses and applies a pre-existing-condition exclusion — asks specifically what a contract's exclusions add on top of this baseline, not whether the baseline exists at all.
