Comparison · Châteauguay vs Candiac · 2026
Two cities on the 30, a $295,000 gap: here is how to decide between Châteauguay and Candiac by budget, commute and profile.
Châteauguay and Candiac are the two ends of the western South Shore on the 30, and $295,000 separate them: a $525,000 median house in Châteauguay in the second quarter of 2026 (flat year over year, +43 % in five years) in 36 days with 302 houses active (+43 %), against $820,000 in Candiac and La Prairie (+4 %, +33 %) in 39 days with 162 houses active, the South Shore's highest median. The condo too: $400,000 vs $450,000. Châteauguay sells the 1960s to 1980s bungalow, the river, Île Saint-Bernard and the Mercier bridge; Candiac sells Square Candiac and the 2010 to 2025 homes, the exo station, the 15 and the 30, and a seller's market in every range. For the price of a Candiac home, you buy a Châteauguay home and keep $295,000; the question is what those $295,000 buy in commute, age of home and resale.
Candiac is $295,000 more expensive in median ($820,000 vs $525,000) because its housing stock is recent (Square Candiac, the 2000 to 2025 sectors) and because La Prairie, in the same sector, adds its historic district and its riverfront; Châteauguay sells mostly 1960s to 1980s homes, and its recent sectors of the northwest sell in between. In five years, Châteauguay rose more (+43 % vs +33 %) because it started lower. The condo is closer: $400,000 in Châteauguay (+11 %, 47 listings) against $450,000 in Candiac-La Prairie (+12 %, 157 listings, +70 %).
