South Shore May 2026: Sales Hold (−1%) but Listings Jump 21%

The South Shore is the paradox of the May 2026 APCIQ statistics: it is both the sector where sales resist best — 1,103 transactions, down just 1% while the CMA falls 7% — and the one where supply is climbing fastest, with listings up 21% year over year. After the picture we drew of the South Shore market this spring, the May numbers sharpen the trajectory: the seller's window is still open, but it is closing.

The CMA's most solid sector

The May 2026 numbers: 1,103 sales (−1%), a stable volume of about $707M, and prices up across the board — single-family at $650,000 (+2%), condo at $400,000 (+2%), plex at $827,000 (+7%, the strongest plex growth in the CMA). Selling times stay short: 31 days for a single-family home and only 28 days for a plex, the regional record. While the Island of Montreal loses 10% of its sales, South Shore demand holds firm, driven by families seeking space and entry prices below the Island's.

But supply is rising faster than anywhere else

The flip side: 3,807 active listings, +21% year over year — the CMA's largest increase — and 1,522 new listings in May (+3% versus May 2025). Most importantly, the APCIQ now ranks the South Shore, with the Island of Montreal, as the only two sectors where supply exceeds the historical average. Concretely: South Shore buyers have regained choice, and every property listed faces more competition than at this time last year.

Why this wave of listings?

Several dynamics converge. Owners who postponed selling in 2024-2025 are cashing in on peak prices. The Brossard and Longueuil condo segment is absorbing deliveries from projects launched at the height of the cycle. And some sellers are anticipating: with regional inventory rising for ten months, better to sell before the tipping point than after. That last logic feeds on itself — and it is precisely what accelerates the market's normalization.

Sellers: act while both curves are favourable

The current combination — prices still rising, short selling times, stable demand — remains one of the best selling configurations in the CMA. But the supply curve says plainly that every quarter of waiting adds competitors. For an owner who planned to sell "within a year or two," moving the date up is objectively defensible. The non-negotiable condition: an asking price anchored to your city's comparable sales from the last 90 days — not to the hoped-for 2025 peak.

Buyers: choice is back

For buyers, +21% in listings changes daily reality: more properties to visit, less pressure to waive conditions, and negotiating power gradually returning — especially for condos. Well-located single-family homes under $650,000 remain contested, but the reflex of systematically overbidding no longer has a reason to exist. The South Shore of June 2026 rewards preparation, not haste.
