Buyer guides
Short guides for anyone buying a house in Québec who wonders where the water goes when it rains hard.
Not in a flood zone? What the map doesn't show
Québec's official flood maps cover watercourse flooding, not rain pooling on a lot. How to check an address, and where Greater Montréal stands in 2026.

The check drops a 100-year, one-hour storm on the ground around the address and shows where the rain water collects. Result by email, no account.
These guides give general information, not legal, engineering or insurance advice. The FloodVerity check is a rain screening for one address, not a hydraulic study; it covers neither river and lake flooding nor sewer backup.
