Quebec City Plex Sales Down 17% in a Market Up 6%

In August 2026, the Quebec City census metropolitan area recorded 677 sales, up 6% year over year, and posted its second-best August in 25 years behind August 2021. Only one of its three segments declined, and it is the one that was carrying the region three months ago. We wrote at the time that plexes were leading the capital.

Three segments, three directions

Data published by APCIQ on September 4, 2026 provides the breakdown. Condos are up 32% year over year, single-family homes up 1%, and plexes down 17%. Three segments, three magnitudes, and a single negative sign.

It takes a beat to see what is unusual about that line. This is not a slowing market with one segment holding up. It is an accelerating market, at its second-best August in a quarter century, with one segment breaking away on its own. Those two configurations read differently, and the second one is the poorly served by the headline numbers.

The reversal, and its date

On July 4, 2026 we published a piece on the plex segment in the Quebec City region. It recorded a 15% rise in plex sales in May 2026 and described the segment as the one dominating the capital. That reading was accurate at its date, and we are not rewriting it: it is what the May figures said.

Three months later, the same segment in the same region prints minus 17%. Going from plus 15 to minus 17 is not an oscillation inside the noise: it is a change of sign on the segment that was carrying the region. That is precisely the value of the August measurement, and it is only visible if you keep the previous one instead of replacing it.

One methodological note, because it bounds what you may conclude: May and August are not consecutive months, and each is compared with the same month a year earlier. We are therefore not measuring a continuous path between the two, but two snapshots taken three months apart. That is enough to establish the reversal, not to date the turning point.

Why the regional total hides it

A regional total sums segments of unequal weight. Here two of them rise, one of them steeply, and that alone carries the whole into positive territory. The total looks good and signals nothing: a reader who stops at 677 sales and plus 6% does not see that a component is dropping out.

This is a limitation specific to aggregation by property type, and it should not be confused with the geographic one. The same total can conceal submarkets moving in opposite directions, and it can also conceal segments moving in opposite directions. Those are two distinct cuts of the same figure and they call for different checks. The one at issue here is the cut by type.

What the 17% does not say

The figure measures completed sales. It does not measure prices. These are different quantities, they do not necessarily move together, and nothing in this number licenses any conclusion about what a plex in Quebec City is worth. We publish no median price for the region in this article: that figure is not measured here, and inventing one would produce a groundless conclusion.

The figure also does not say why the decline is happening. Transaction volume can fall because fewer buyers show up, because fewer sellers list, or because the two meet less easily on price. Those three causes call for opposite responses from an owner, and a breakdown by segment cannot separate them.

What a plex owner takes from it

The useful reading is about buyer pool depth, not about value. Fewer completed transactions in a segment generally means fewer candidates facing each listing. That shows up first as a longer selling time, then as a weaker negotiating position, and only possibly as a price.

In practical terms, an owner who was considering selling a plex in the region over the coming months is better served by lengthening the marketing horizon than by reflexively adjusting the price. A price adjustment decided on a volume statistic corrects a quantity that statistic does not measure.

The check that remains

One month of regional data decides nothing for a specific building. The check that matters is local and fits in one question: how many plexes actually sold in your area over recent months, and how long they took. A regional segment down 17% can perfectly well cover an area where nothing changed, as well as one where the decline is sharper still.

Next month brings a third measurement, and that is what will say whether August was an isolated drop or the start of a run. One negative month after a rise is not a trend; two begin to make one. Until then, the reasonable position is to treat this number as a warning about selling time, not as a verdict on value.
