Quebec Real Estate, September 2026: Condo and Plex Sales Down 13%

The APCIQ has released its September 2026 statistics for Quebec province, compiled from the Centris system: 7,045 residential sales, compared with 7,584 in September 2025, a 7% decline. That headline hides a sharp split between property types. Our June 2026 Quebec market report laid out a spring month; this one isolates September and asks a single question: why did condo and plex sales fall three times faster than single-family sales, when supply rose at a similar pace everywhere?

September 2026 numbers by property type

The figures below compare September 2026 with the same month in 2025 for Quebec province as a whole. They all come from the same APCIQ release, so the categories can be compared with one another without mixing sources.

Three more totals round out the picture. New listings for the month reached 15,378, compared with 13,650 in September 2025, up 13%. Sales volume came to $3,918,161,072, compared with $4,178,715,551, down 6%. And year-to-date sales stand at 71,323, compared with 75,274 at the same point last year, down 5%.

Supply rose everywhere, at the same pace

The first useful fact sits in the active listings column. They rose 23% for single-family homes, 22% for condos and 28% for plexes. Only six points separate the fastest-growing category from the slowest: on the supply side, the three categories barely differ.

That is what makes the comparison readable. Had condo supply jumped far more than single-family supply, the sales gap might simply reflect that. It did not in September 2026. Since supply moved in a comparable way across all three categories, the difference in behaviour lies elsewhere, on the side of completed transactions.

Condo and plex sales fell three times faster

In percentage terms the gap is stark: condos down 13%, plexes down 13%, single-family homes down 4%. Expressed as actual sales, it takes a different shape that is worth knowing before quoting these numbers.

• single-family homes lost 211 sales, from 5,030 to 4,819;
• condos lost 220 sales, from 1,735 to 1,515;
• plexes lost 103 sales, from 792 to 689.

In number of transactions, single-family homes and condos fell by almost the same amount. The percentage gap comes from the size of each category: 220 fewer sales weigh heavily on a base of 1,735, much less on a base of 5,030. Both readings are correct. The percentage reading tells you which category lost the largest share of its usual activity; the raw count tells you where the drop in the provincial total came from.

Selling times lengthen where sales fell most

The second fact confirms the first through a different measure. Median days on market rose by 14 days for condos, from 48 to 62. They rose 6 days for plexes, from 48 to 54, and only 2 days for single-family homes, from 45 to 47.

The order matches the sales figures: the category with the steepest drop in volume is also the one where a property takes longest to find a buyer. Two independent measures, number of sales and selling time, point the same way. That is what justifies speaking of a slowdown genuinely concentrated in condos, and to a lesser extent plexes, rather than a one-month counting accident.

What these numbers show, and what they don't

What is established: in September 2026, across the province, the sales decline was concentrated in condos and plexes while supply rose at a similar pace in all three categories, and selling times lengthened most where sales fell most.

What is not established, and should not be written:

• The cause. The APCIQ measures sales, listings, prices and selling times, never a buyer's reasons. Hypotheses can be raised, for instance that condo buyers and plex investors respond differently to financing conditions, but none of them is measured by this data.
• A trend. This is one month compared with the same month a year earlier. One month is not a direction.
• Any specific area. A provincial figure aggregates very different markets. It says nothing about the selling time or price of a condo on a particular street.
• The movement in median prices. The single-family median rose 3%, the plex median 4%, and the condo median held steady. These changes do not mean every property gained value: our article on the mix effect on the median price explains why.

For condo and plex sellers, in practice

For a seller, the most concrete consequence of September 2026 is not price, it is time. The provincial condo median held at $400,000, but the median selling time grew by two weeks. A listing planned around last year's timeline risks being miscalibrated.

• set the price from recent comparable sales in your own area, not from a provincial median;
• build a timeline that allows for a longer sale, especially if buying another property depends on it;
• check how many comparable listings are active in your area, since supply grew in every category;
• for a plex, prepare in advance the documents the buyer and their lender will ask for, so as not to stretch an already longer selling time.

For single-family sellers the signal is milder: sales down 4% and two extra days on market. Supply still rose 23% in that category too, which calls for the same discipline on the asking price.
