Ottawa's purpose-built rental vacancy rate rose to 3.0% in October 2025 from 2.6% a year earlier, and the average rent climbed to C$1,727 across all bedroom types, per CMHC โ figures that cover only the Ontario side of the Ottawa CMA, since CMHC publishes Ottawa and Gatineau separately. Ottawa sits under Ontario's 2026 rent increase guideline of 2.1% like the other Ontario cities in this set.
Ottawa's numbers cover the Ontario side of the CMA only
CMHC's Rental Market Survey data tables for Ottawa record the purpose-built private apartment vacancy rate rising from 2.6% in October 2024 to 3.0% in October 2025, with the average rent across all bedroom types up from C$1,673 to C$1,727 โ a 3.2% year-over-year increase. CMHC treats Ottawa-Gatineau as a split CMA, publishing the Ontario portion (Ottawa) separately from the Quebec portion (Gatineau); the figures here describe Ottawa only, and are not comparable to a blended Ottawa-Gatineau figure without adjustment.
Ottawa's asking rent is published โ but paid rent is suppressed
Statistics Canada's experimental asking-and-paid-rent series (table 46-10-0092-01) puts Ottawa's (Ontario-part) 2-bedroom apartment average asking rent at C$2,360 for the 2026 Q2 reference period. Unlike every other city in this batch, StatCan's paid-rent figure for Ottawa is suppressed in this vintage of the table โ no comparable average paid rent is published, so no asking-vs-paid gap can be shown for Ottawa the way it can for the other six cities. Do not substitute the asking rent for a paid-rent estimate; StatCan itself withholds the figure rather than approximating it.
Ontario's guideline, and government employment's effect on rent stability
Ottawa falls under Ontario's 2026 rent increase guideline of 2.1% for most sitting tenancies, the same rule as Kitchener-Waterloo and London. Set against CMHC's measured 3.2% average rent increase, the gap between the guideline and market rent growth is narrower in Ottawa than in London (6.1% measured growth) or Halifax under its own provincial cap โ consistent with Ottawa's federal-government-anchored employment base producing steadier, less volatile rent movement than markets more exposed to swings in population growth or resource-sector activity.
As with every Ontario CMA, any Ottawa unit first occupied for residential purposes after November 15, 2018 is exempt from the guideline entirely, so newer purpose-built towers in Ottawa's core see uncontrolled rent on both turnover and renewal.
Ontario land transfer tax and financing a larger Ottawa multi-unit building
Ottawa levies no municipal land transfer tax of its own โ only Ontario's provincial LTT applies. Per the province's bracket schedule (0.5% to C$55,000; 1.0% from C$55,000 to C$250,000; 1.5% from C$250,000 to C$400,000; 2.0% above C$400,000), a C$700,000 Ottawa purchase works out to: C$55,000 ร 0.5% = C$275, plus (C$250,000 โ C$55,000) ร 1.0% = C$1,950, plus (C$400,000 โ C$250,000) ร 1.5% = C$2,250, plus (C$700,000 โ C$400,000) ร 2.0% = C$6,000. Total Ontario LTT = C$10,475. A qualifying first-time buyer can apply the province's C$4,000 land transfer tax refund against that bill, bringing the net LTT to C$6,475.
For an Ottawa investor scaling into a 5+ unit building rather than a single condo, CMHC's MLI Select programme changes the financing math: at a minimum 50 points, maximum LTV is 85% with a maximum 40-year amortization; at 70 points, maximum LTV rises to 95% with up to 45 years; at 100 points, maximum LTV stays up to 95% with amortization extending to 50 years, and all three tiers require a minimum 1.10 debt coverage ratio. Points are earned across three categories โ Affordability (up to 100 points for existing buildings, up to 50 for new construction), Energy Efficiency/GHG Reductions (up to 100 points), and Accessibility (up to 40 points) โ which rewards exactly the kind of below-market-rent, efficiency-retrofit building that Ottawa's steady, government-anchored rental demand makes a realistic hold.
Methodology
Vacancy and rent figures are CMHC's October 2025 Rental Market Survey data tables for the Ottawa CMA (Ontario side only), purpose-built private apartment universe, all bedroom types combined. The StatCan asking-rent figure is Statistics Canada's experimental table 46-10-0092-01 for 2-bedroom apartments, reference period 2026 Q2; that table's paid-rent value for Ottawa is suppressed in the source and is not estimated here. Land transfer tax and MLI Select figures apply Ontario's and CMHC's own published schedules directly; no specific MLI Select premium percentage is cited, since CMHC's own MLI Select page does not itself state those figures (see notes).
