Montréal property records check: frequently asked questions

From public sources: the Ville de Montréal’s open data (building permits since 1990, assessment units, notices of deterioration, the right of first refusal, housing inspections, heritage sites and inventories, land use, street trees), the Quebec assessment roll published by the Ministère des Affaires municipales et de l’Habitation, and the SPVM. Every finding names its source.

No. Records show what was permitted and registered, not the condition of the building. Use the report together with a pre-purchase inspection, the seller’s declaration, the certificate of location and advice from your broker and notary.

The address page is free. A full report is $20 CAD for one Montréal address; 5 reports cost $75 ($15 each) and 10 reports cost $100 ($10 each), with credits for any address, any time. In Québec, Laval, Gatineau, Longueuil and Sherbrooke the report is shorter and costs less: $10 for one, $35 for 5 and $50 for 10, with credits for addresses outside Montréal only. Paid once by card through Stripe, no subscription.

Yes. Duplexes, triplexes and other plexes get their own page. For condos we check the building as a whole and list the co-ownership documents to ask for.

What the records flag for the property, the assessed value on the 2026-2028 roll, an estimate of the welcome tax, the number of dwellings, the year built, the most recent permit, the metro and street trees.

For each finding: what the record says, what it means and what to do. The full permit list since 1990 with the work descriptions, the land and building values, the welcome tax by bracket, the cadastre and roll numbers, police-reported incidents nearby, questions for the seller and the notary, and a PDF.

Montréal can register a right of preemption on some properties it may want for housing, parks or other projects. Before the sale closes the owner must notify the City, which has 60 days to buy at the same price and conditions. The report tells you if the address is on the list.

A notice the City registers on the land register when a building breaks the by-law on the maintenance of buildings. It stays on the title and the obligations pass to the buyer until the City lifts it.

Yes, partly. Québec, Laval, Gatineau, Longueuil and Sherbrooke have a page for every address with the assessed value, the welcome tax, flood zones and contaminated sites. Building permits, City notices and heritage are available for the Ville de Montréal only for now.

Yes. We do not tell owners or brokers who looked up an address. See the privacy policy.
