Sainte-Catherine sits on the St. Lawrence shore facing LaSalle, between Kahnawake and Delson. The city was built mostly between 1981 and 2000: more than half of its dwellings date from that period, according to the 2021 census. It is an area I cover on the same footing as the others.
A city that faces the river
The waterfront structures the local market. The 2.7 km riverside promenade, the RécréoParc and the Seaway lock give the streets near the river an appeal you do not find further inland.
The Kateri sector, around the church and the Hilaire-Guérin house, is the historic core of the city.
The boulevard Marie-Victorin corridor is mainly single-family: detached homes on residential lots, the product most families in the area are looking for.
Buildings under five storeys account for close to 30% of dwellings. For a first-time buyer or an investor, that is a real entry point into the Roussillon area.
What to check here
Flood zone mapping, especially near the Saint-Régis River. Quebec overhauled its flood zone framework in 2026 and the regional mapping is being updated: the map in force on the date of your offer is the one that counts.
Sewer backups and basement water. The rain from storm Debby in August 2024 flooded basements in several sectors. Ask the seller what happened in their home and whether a backwater valve is installed.
The age of the systems in homes from the 1980s and 1990s: roof, windows, water heater and French drain.
Selling and buying in Sainte-Catherine
Price is read against Delson, Candiac and Saint-Constant, because buyers compare all four cities. A list price that ignores those comparables rarely corrects without losing weeks.
