Source: Centris, Q3 2026 (July to September). City of Châteauguay, Q3 2026 (July to September), change compared with the same quarter of 2025. For condos, Centris does not publish a quarterly price due to too few transactions: the figures cover the last four quarters. For plexes, the number of sales (22 over four quarters) is too low for Centris to publish a median price.
Medians by sector: last 4 quarters (Centris).
exo buses leave from the Châteauguay terminus for Angrignon metro station and, at rush hour, for downtown Montréal (Terminus Centre-ville). Highway 30 crosses the city. To reach Montréal, Route 138 leads to the Honoré-Mercier Bridge; an eastbound reserved lane helps avoid part of the congestion on the approach to the bridge.
