Ottawa rents are softening in 2026: a reality check for small landlords

For the last few years, owning a rental in Ottawa meant riding a one-way escalator. Rents went up, vacancy stayed near zero, and if a tenant left you had three showings and a signed lease by the weekend. That escalator just stopped. If you own a door or two in this city, the numbers behind your investment changed in 2025, and most small landlords haven't adjusted their assumptions yet.

The shift is real, and it's measurable

CMHC's latest rental market report put Ottawa's vacancy rate near 3%, up from roughly 2% a year earlier. Urbanation, which tracks purpose-built buildings, had stabilized vacancy at 3.5% by the fourth quarter of 2025. Neither number sounds dramatic on its own. The direction is what matters. Vacancy climbing while rents were still being pushed higher is the first sign that landlords have lost pricing power.

The clearest tell is what building owners are doing to fill units. Urbanation reported that 64% of Ottawa rental projects were offering promotions or incentives by late 2025, up from 43% a year earlier. When two-thirds of your competition is dangling a free month or a gift card, your "market rent" is not really the market rent anymore.

This is a supply story, not a demand collapse

People aren't leaving Ottawa. Demand is fine. What changed is that supply finally caught up, and then some. Ottawa delivered 4,646 new purpose-built rental units in 2025, a multi-decade high, with a similar number projected for 2026. That is the largest wave of new rental supply the city has seen in close to 50 years. Net absorption stayed positive, but not fast enough to soak up everything that opened its doors at once.

For a small landlord this matters because you are no longer competing only with the duplex down the street. You are competing with a brand new building that has a gym, in-suite laundry, and a leasing agent authorized to give away the first month.

The market split in two, and that's the opportunity

Here is the part most of the coverage misses. The softening is not spread evenly. Vacancy in Ottawa buildings built after 2015 hit 6.7%, more than double the citywide average. Meanwhile the lower-rent, older stock sat below 1% vacancy. Read that again, because it is the whole game.

The pain is concentrated in shiny new supply priced at the top of the market. The boring, older, below-market unit in a decent location still rents in a weekend. If you own that kind of unit, you are mostly insulated. If you are shopping for a rental, that is exactly what you want to buy, and it is the opposite of what most first-time investors chase.

Fix your underwriting before you buy anything

The spreadsheet math a lot of investors were using in 2022 is now wrong. A few corrections I'd make today.

Stop underwriting 1% vacancy. Budget for a real turnover month. On a $2,000 unit, one vacant month plus a small make-ready is $2,500 gone. If your annual cash flow can't absorb that, the deal is thinner than you think.

Stop assuming 5% annual rent growth. For a sitting tenant you are capped by the provincial guideline anyway, which is a fraction of that. I wrote about the gap between guideline and market rent here. For a turnover you now have to price against buildings handing out incentives, so your bump on turnover is smaller than it was.

Underwrite the property that is under-rented, not over-rented. A unit sitting $300 below market is a built-in raise you control over time. A unit already at the top of the market has nowhere to go and everywhere to fall.

Where the actual money is right now

A softer rental market is not bad news for a buyer. It is the opposite. Less competition on the purchase side, more sellers who are tired of managing an underperforming rental, and sellers who padded their pro formas with rents the market will no longer pay. That last group is where you negotiate.

The value-add plays still work. Buying a house and adding a legal secondary suite remains one of the few ways to manufacture cash flow in this city, and I ran that math in detail here. Cap rates have not moved enough to get excited about on their own, but the combination of a motivated seller and a below-market unit is where the returns hide. If you want the framework I use, here's how I think about cap rates on Ottawa rentals.

What I tell investor clients this summer

Don't panic-sell a performing older unit because the headlines say vacancy is up. Your unit is probably in the under-1% bucket, not the 6.7% bucket.

If you're buying, use the softness. Make the offer that assumes a vacant month and a rent that actually clears. If the seller's numbers only work at fantasy rents, walk.

And if you're carrying a new-build condo you bought to rent, look hard at your break-even. That is the corner of the market feeling the most pressure, and pretending otherwise on your own spreadsheet doesn't change what a tenant will pay.

The escalator isn't coming back tomorrow. CMHC expects conditions to firm up again as the supply wave gets absorbed, but for the next few quarters the advantage sits with tenants and with patient buyers. If you own a rental or you're hunting for one, this is a good moment to get your numbers checked by someone who works this market every day.
