CostQuebec uses a civil law system (rather than common law elsewhere in Canada), closings are handled by a notary rather than a lawyer, and the welcome tax is billed separately by the municipality after closing rather than collected at closing — three structural differences worth understanding before buying there.
Civil law and the notary's role
Quebec is the only Canadian province operating under a civil law system rather than the common law system used everywhere else in Canada — a foundational legal difference that shapes how property transactions are structured. Real estate closings in Quebec are handled by a notary, a distinct legal professional role from a common-law lawyer, and notaries in Quebec have specific public-officer responsibilities in recording and certifying the transaction that differ from how a lawyer functions in other provinces.
The welcome tax timing
As covered in our dedicated welcome tax guide, Quebec's land transfer duty is billed separately by the municipality after closing, not collected by the notary at closing — a genuine structural difference from how every other province handles this cost, and one that catches buyers relocating from elsewhere in Canada off guard if they're not specifically warned about it in advance.
Financing and process norms
The overall financing process — mortgage pre-approval, the stress test, CMHC insurance rules — follows the same federal framework as the rest of Canada, so the core mortgage math doesn't change. What differs is mainly the legal and closing process itself: expect to work with a notary rather than a lawyer, and budget for the welcome tax as a bill that arrives later rather than one due at closing.
