Two neighbouring areas, the pros and cons of each side by side, and the con that most often decides between the two.

Saint-Constant, Delson and Sainte-Catherine or Châteauguay, the pros and cons side by side. Saint-Constant, Delson and Sainte-Catherine: pro, A suburban house with land, a train station on foot in each town, the river and a price below Candiac and La Prairie. Con, Lived by car and train: no dense city or lively old village. Châteauguay: pro, A house with land under $550,000, the Châteauguay River, Île Saint-Bernard and the Mercier Bridge toward LaSalle. Con, The Mercier Bridge rules: recurring roadwork, jams, and a single direct link to the island. For families who want a suburban house with a lot, a station on foot and the river, at a price below Candiac and La Prairie; for those working downtown by train or in Brossard via the 30. For families who want a house with a lot under $550,000, the river, Île Saint-Bernard and a bridge to Montreal; for West Island anglophones who cross over.

Saint-Constant, Delson and Sainte-Catherine and Châteauguay are neighbours, and buyers often hesitate between the two. Here are the pros and cons of each, side by side, written by a team that sells in both; the figures are those published by the APCIQ for the second quarter of 2026, and nothing is embellished.

Saint-Constant, Delson and Sainte-Catherine: the pros and cons

The pros of Saint-Constant, Delson and Sainte-Catherine

• A suburban house with land, a train station on foot in each town, the river and a price below Candiac and La Prairie.
• Three quiet, family suburbs, with downtown by train and Brossard by highway 30.
• Getting around. The exo Candiac line stops at Saint-Constant, Delson and Sainte-Catherine stations, with Central Station at the end; exo Le Richelain buses reach the Panama terminus in Brossard and the REM.

The cons of Saint-Constant, Delson and Sainte-Catherine

• Lived by car and train: no dense city or lively old village.
• The Candiac train has limited departures outside peak hours; evenings and weekends mean the car.
• The industrial park and rail lines in Delson and Saint-Constant: noise and trucks depending on the street.

Châteauguay: the pros and cons

The pros of Châteauguay

• A house with land under $550,000, the Châteauguay River, Île Saint-Bernard and the Mercier Bridge toward LaSalle.
• The best-supplied house market in the western South Shore (302 listings): choice for the buyer.
• Getting around. The Châteauguay bus terminus (exo Sud-Ouest) links the town to the Angrignon terminus and the metro; local buses serve the centre.

The cons of Châteauguay

• The Mercier Bridge rules: recurring roadwork, jams, and a single direct link to the island.
• No train or metro; toward Longueuil, Laval or downtown, trips are long.
• A 1960s-to-1980s housing stock to renovate, and prices flat over one year: appreciation is slow.

Head to head, criterion by criterion

Our verdict

Saint-Constant, Delson and Sainte-Catherine: For families who want a suburban house with a lot, a station on foot and the river, at a price below Candiac and La Prairie; for those working downtown by train or in Brossard via the 30. Châteauguay: For families who want a house with a lot under $550,000, the river, Île Saint-Bernard and a bridge to Montreal; for West Island anglophones who cross over.
