Ottawa apartments were soft before the citywide market slowed

Ottawa’s balanced-market headline hid a persistent apartment gap

Ottawa’s apartment market was softer than the citywide market well before the abrupt August slowdown. Retained reports put apartment inventory 2.2 months above the citywide measure in March, 1.5 months above it in April and 2.0 months above it in June. That consistency matters more than any one month: the segment had a separate absorption problem while the overall market was still being described as balanced.

Months of inventory divides available stock by the current sales pace. It is not the age of a listing, a vacancy rate or a count of unfinished apartments. The retained figures refer to the board’s reporting geography and aggregate apartment-style properties. They cannot describe every building or neighbourhood, but they do show that the citywide balance was a poor proxy for this segment.

August broadened the weakness. Total sales fell 24.4% from July, compared with a median July-to-August decline of 5.8% over the previous ten years. Citywide months of inventory rose from 3.5 to 4.5, while apartments reached 6.3 months. OREB also found that terminations, cancellations and expirations had become more prominent relative to completed sales. A falling active-listing count therefore did not mean buyers had absorbed the available homes. [Ottawa August market report]

A large construction pipeline changes the next question

OREB’s June report cited 17,212 Ottawa housing units under construction in May, nearly 14,000 of them apartments, while completed and unabsorbed apartment inventory was only 37 units. Those categories describe different stages. Construction volume is a future delivery risk; completed and unabsorbed inventory is a current unsold-new-home measure. Neither number can be added to resale listings or treated as immediate excess supply. [Ottawa June market report]

The same report cited a 3.0% primary-rental vacancy rate in 2025 and a much tighter 0.6% vacancy rate for condominium rentals. That split provides a plausible outlet for some completed apartments, but it does not guarantee investors can achieve the rent or carrying-cost return they require. The practical pressure point is the handoff from construction to completed rental or resale inventory, not the construction count alone. [Ottawa June market report]

The Bank of Canada held its policy rate at 2.25% on September 2 while noting higher long-term bond yields and renewed trade risks. Ontario’s budget announcement also described a combined federal and provincial full 13% HST rebate for qualifying new homes purchased from April 1, 2026 through March 31, 2027, subject to federal legislation. The retained announcement says the benefit could reach $130,000, with the full amount available on qualifying homes priced at $1 million or less. The measure may pull some new-home decisions forward, but it cannot be treated as support for existing resale apartments or as proof that every project qualifies. Fixed mortgage offers can remain restrictive even during a policy-rate hold. These policy channels can affect absorption, but neither is presented as the measured cause of Ottawa’s August decline.

Forecast: apartments remain Ottawa’s softest major segment through 2026

The conditional forecast is that apartment-style properties retain the highest months of inventory among Ottawa’s three major property types in the September through December 2026 reports. Confidence is moderate. The call rests on a gap observed in three retained spring reports, 6.3 months of apartment inventory in August, and a large apartment construction cohort moving toward completion. It assumes no sudden fall in financing costs and no unusually strong leasing or investor demand.

The forecast fails in a month if apartment inventory falls to or below both single-family and townhouse inventory. A sustained recovery in apartment sales, fewer non-sale removals and completed projects leasing without material incentives would weaken the broader softness thesis. The forecast does not assign a price target: property mix, concessions and neighbourhood differences are not measured well enough to support one.
