Toronto Rentals Hit 5-Year Vacancy High|Record Construction Not Stopping

A Market That Built Too Much at the Worst Possible Moment

One in twenty rental apartments in greater Toronto sat empty in the first quarter of 2026. That is the highest vacancy rate since the onset of the pandemic — 5.4 per cent, more than double the 2.6 per cent recorded just two years ago, according to a new report from real estate consultancy Urbanation. And here is what makes that figure harder to dismiss: the construction pipeline is at a multi-decade high at the same time.

Canada's markets were moving on multiple fronts on Monday. Shell announced a $22 billion deal to acquire ARC Resources, making Canada a declared "heartland" for the British energy giant and sending ARC shares surging. Rogers Communications said it was offering voluntary buyout packages to roughly half its workforce — about 12,500 employees — as the telecom giant grapples with $34.7 billion in long-term debt and slowing industry revenue. Prime Minister Mark Carney told the CBC he was in no hurry to accept a thin tariff-relief deal with Washington, while a Quebec furniture manufacturer, South Shore Furniture, announced it would shut both its plants and lay off 126 workers, blaming dumping from Asian rivals and lost U.S. sales. The mood was far from uniform. Yet behind all of that activity, the Toronto rental data released Monday carried a signal that the headline deal flow was obscuring.

The Urbanation report surveyed purpose-built rental units opened since 2000. It found that 8 per cent of apartments were either vacant or in the process of turning over — a record high. Two in three buildings surveyed were offering incentives to attract tenants. Nearly half were offering two months of free rent.

Why Is Supply Winning When It Wasn't Supposed To?

For the better part of four years, Canada's rental story was one of shortage. Vacancy rates in Toronto fell to near zero in 2022 and 2023. Rents climbed at double-digit annual rates. Developers responded by breaking ground at the fastest pace in a generation — more than 10,000 new units started in the greater Toronto and Hamilton area in the past twelve months alone, with a record 8,984 units set to open to tenants in the next year.

The problem is that demand did not hold long enough for those units to fill up.

Two forces reversed the market simultaneously. First, temporary resident inflows dropped sharply as federal immigration policy tightened. Second, existing residents began leaving Toronto for smaller cities. Royal Bank of Canada estimates that Toronto's population is expected to actually shrink in 2026 — a statement that would have seemed implausible eighteen months ago when waitlists for a one-bedroom apartment stretched for months. Urbanation president Shaun Hildebrand described the current environment as "a window of opportunity for renters to capitalize on improved affordability."

That framing is accurate for new tenants. For current ones, it is more complicated. Landlords who are competing for new tenants with free-rent incentives are simultaneously raising rents on existing tenants and resetting to higher market rates when units turn over. RBC's own national rental report expects vacancy rates to keep climbing through the near term before population growth reaccelerates around 2028.

Here is where the tension tightens: developers are still building. Despite rising vacancies and declining asking rents in the new-lease market, groundbreakings hit a multi-decade high. That is not irrational — projects started in 2024 and 2025 were committed when market conditions looked entirely different. But completions scheduled for the next twelve months will add roughly 9,000 more units into a market where the existing stock is already offering two months of free rent. The pipeline and the vacancy rate are moving in the same direction at the same time. That has not happened in Toronto in at least a decade.

Two Scenarios, One Variable

The central question is not whether rents will fall further in the short term — they likely will, at least in the new-lease market. The question is whether this correction stabilizes before the development math breaks.

The case that this stays manageable rests on the 2028 timeline. If federal immigration targets recover to historical levels within two years, and if Toronto's population starts growing again before the next wave of completions comes online, then the current vacancy spike looks like a temporary overshoot — painful for landlords, useful for renters, and ultimately self-correcting because developers will slow permitting if pre-leasing rates deteriorate. The Urbanation data already shows incentive competition intensifying, which is the market's way of clearing inventory without a hard price break.

The case for a harder correction centers on the construction pipeline itself. Roughly 9,000 units are already committed for delivery in the next twelve months. Those will open regardless of demand. If population shrinkage in Toronto continues longer than RBC projects — perhaps because Carney's immigration recalibration or tariff-driven job losses keep new arrivals down — then vacancy could approach the 6.3 per cent level last seen in early 2021 before stabilizing. At that point, the free-rent incentives being offered today would become permanent rent reductions in everything but name, and several smaller landlords carrying floating-rate debt would face real cash flow stress.

Evidence leans toward the manageable scenario. The vacancy rate has not yet reached 2021 levels. The Bank of Canada's rate path, which is the main variable for floating-rate landlords, is likely to ease modestly if domestic demand slows further — the upcoming Bank of Canada meeting will be the first clear test. And the Shell-ARC deal announced Monday, if it closes in the second half of this year, is a marker that foreign capital still sees long-term value in Canada's economic base, which indirectly supports employment in western Canada's energy corridor.

But that confidence depends entirely on one variable: the population trajectory. If Statistics Canada's mid-year population estimate, due this summer, shows Toronto shrinking faster than RBC's base case, the window of opportunity for renters will remain open longer than developers priced in — and the question of who absorbs the carrying costs shifts from renters to investors. Watch the Bank of Canada meeting and the June population data. If both confirm RBC's 2028 recovery thesis, the current vacancy peak is likely the ceiling. If either surprises to the downside, the ceiling just moved higher.
