Closed sales on Centris from 2018 to September 2026: 1,174 houses bordered by a body of water and 14,358 single-family homes in all. A year with fewer than 10 waterfront sales is left blank (n/a). When a year has few sales, its median can move by tens of thousands of dollars without the market having changed.

Is the waterfront worth paying for in the Bas-Saint-Laurent?
In the Bas-Saint-Laurent, the waterfront costs $32,000 (+11%), not much. It means waterfront houses look like the others: same age, same size, and sometimes more modest shores (stream, narrow river, pond). The buyer who wants the water pays almost the same house; the seller with a real lakefront must bring out what the median does not see.
How to read these figures
One median per year for waterfront houses in the Bas-Saint-Laurent and one for all houses. Waterfront = the Centris listing reports a body of water bordering the lot (lake, river, the St. Lawrence, pond, canal, sea, reservoir or stream). The gap between the two does not measure what the water is worth for a given house: it measures what the market paid for the typical waterfront house versus the typical house of the region. Fewer than 10 waterfront sales in a year: median left blank. Series from 2018, the year the field appears.
