Comparison · Saint-Jean-sur-Richelieu vs Chambly · 2026
Two cities on the Richelieu, a $218,000 gap: here is how to decide between Saint-Jean-sur-Richelieu and Chambly by commute, budget and profile.
Saint-Jean-sur-Richelieu and Chambly are neighbours on the Richelieu and on the 35, and $218,000 separate them: a $509,000 median house in the Saint-Jean and Saint-Luc sector in the second quarter of 2026 (-6 % year over year, +44 % in five years) in 31 days ($578,000 for the whole city, Iberville included), against $727,000 in Chambly (+10 %, the South Shore's strongest rise, +43 % in five years) in 36 days with 180 houses active. The condo follows: $350,000 vs $412,500, in 27 and 28 days. Saint-Jean sells old Saint-Jean, the Royal Military College, the Chambly canal, Saint-Luc and its recent homes, and the South Shore's lowest entry price; Chambly sells the basin, the fort, the canal, the recent sectors along the 10 and proximity to the Champlain bridge via the 10. The choice comes down to the commute (the 10 or the 35), the budget and the water.
Chambly is $218,000 more expensive in median ($727,000 vs $509,000 in the Saint-Jean and Saint-Luc sector) because it is closer to Montreal via the 10, because its recent sectors and its waterfront on the basin pull the median, and because it rose 10 % in a year while Saint-Jean fell 6 %. Saint-Jean-sur-Richelieu has the South Shore's lowest entry price for the house and the condo ($350,000), with Iberville and Saint-Athanase ($577,950, 46 days) on the east bank. In five years, both rose the same (+44 % and +43 %). The full portraits are on best real estate broker in Saint-Jean-sur-Richelieu and real estate broker in Chambly.
