Trois-Rivieres: Market Up 9%, Plex Up 48%

We covered Trois-Rivieres affordability in our regional market portrait this summer. The second quarter of 2026 adds a fact that portrait did not cover: the plex recorded 80 transactions there, up 48%, in a region already growing while Quebec contracts. This article covers that segment only.

A segment rising inside a region already going the other way

Start with the provincial benchmark. Quebec recorded 27,296 sales in the second quarter of 2026, down 5%. The Trois-Rivieres metropolitan area recorded 437, up 9%. Fourteen points therefore separate the region from the provincial trend.

The plex does better still. Its 80 transactions represent a 48% year-over-year increase, more than five times the pace of the region hosting it. A segment outperforming a market that is itself outperforming deserves a look behind the percentage.

One caution about large percentages on small numbers. Eighty quarterly transactions is a modest base: a swing of a few dozen units mechanically produces a spectacular percentage. The movement is real; its relative scale should be read with the base in mind.

Volume surging, price barely moving

This is the quarter's most instructive fact. The median plex price in Trois-Rivieres rose 3%. Over the same period and in the same region, single-family rose 7% and condominiums 1%. The segment gaining most in volume is therefore not the one gaining most in price.

The explanation lies in the balance between supply and demand. When transaction volume jumps without prices accelerating, supply was sufficient to absorb the extra demand. Regional active listings reached 420, up 34%: there was indeed enough inventory to feed that surge in sales.

That is a healthy configuration, and a rare one. A market where volume rises faster than prices stays accessible to the next buyers. Conversely, a volume increase paired with a price spike would have signalled scarcity, and therefore a window closing.

The region's only selling time that lengthened

The median selling time for a Trois-Rivieres plex is 29 days, up 3 days year over year. The other two types moved the other way: single-family dropped to 21 days, down 7, and condominiums to 34 days, down 4.

A lengthening selling time alongside surging volume is not contradictory. Both measures answer the same cause: more buildings available. Each plex brought to market faces more direct competition, so takes slightly longer to find its buyer, even as the segment as a whole transacts more.

Those 29 days remain clearly below the provincial plex benchmark of 43 days. A plex still sells appreciably faster in Trois-Rivieres than across Quebec, despite the lengthening.

The city up 12%, the periphery down 7%

The figure that rules out reasoning from a regional average is this one: the city of Trois-Rivieres rose 12% while its periphery fell 7%. Nineteen points separate the two territories inside the same metropolitan area.

For a plex that distinction is decisive. A rental building is valued on the rental demand of its immediate sector, and that demand concentrates where jobs, services and educational institutions sit. The urban core concentrates all three; the periphery, far less.

In practice, the 48% volume increase does not spread evenly across the territory. An investor reading that figure without crossing it against the city-periphery gap risks applying an urban conclusion to a building that is not in the right market.

What the quarter signals to an investor

The Trois-Rivieres plex picture comes down to four findings: volume surges, price rises modestly, selling time stretches slightly, and available supply is up 34%. Together they describe an active segment where the buyer keeps choice, which is not the metropolitan configuration.

The valuation rule does not change for all that. A plex is not bought on a regional statistic: it is bought on its actual leases, the past year's expenses, the condition of the structure and the applicable zoning. A 48% volume increase says something is happening in the sector; it says nothing about the yield of any particular building.

For an owner considering a sale, the reading is rather favourable: the number of buyers has clearly grown. But the trade-off is real. With 34% more active listings, your building is compared against more alternatives than a year ago. The asking price therefore tolerates less approximation than a quick glance at the growth percentage might suggest.
