Forty-eight hours ago, the President of the United States doubled tariffs on Canadian steel to 50 percent. Then he backed off. Then the original 25 percent tariffs — with zero exemptions — took effect at midnight anyway.

If that feels like whiplash, you’re not alone. And if you’re buying, selling, renting, or managing property in the Greater Toronto Area right now, the ripple effects are already showing up in places that matter more than the headlines: your mortgage rate, your listing price, and your next lease renewal.

Here’s what’s actually happening — and what it means for your next move.

The Bond Yield Story Nobody’s Talking About

Most people watch the Bank of Canada rate for signals on mortgage costs. Right now, that rate sits at 2.25 percent, and the March 18 announcement is widely expected to be another hold. On the surface, nothing has changed.

But underneath, something significant is shifting. The five-year Government of Canada bond yield — the benchmark that drives fixed mortgage rates — jumped from 2.7 percent to 3.0 percent since the Iran conflict began in early March. That’s the highest level since the start of 2026, and lenders have already responded by hiking fixed rates 10 to 15 basis points. The best five-year fixed rate has climbed from 3.69 percent to 3.84 percent in a matter of days.

Meanwhile, five-year variable rates remain at 3.35 percent — still below fixed, but the spread that was 85 to 95 basis points just two weeks ago is now tightening. The variable-rate advantage is shrinking in real time.

“Everyone’s watching the Bank of Canada, but the bond market is where the action is,” says Kai Min, Licensed Sales Representative with Royal LePage Meadowtowne Realty. “Fixed rates went up this month even though the central bank didn’t move. The rate you can lock in today is not the rate you’ll see next month — and that applies in both directions.”

The Tariff Picture: Uncertainty as a Market Force

The steel tariff drama — Trump escalating to 50 percent, Ontario Premier Ford pausing his electricity surcharge, and the tariffs settling back to 25 percent — played out in less than 24 hours. Canada has filed a WTO dispute resolution request, but the 25 percent tariffs on steel and aluminum are now in effect with no exemptions.

The broader economic toll is significant. Analysis from the Globe and Mail shows Canadian GDP has already been reduced by 1.5 to 2 percent through the 2025–26 tariff cycle. Canadian households are absorbing an estimated $1,700 to $2,000 in additional annual costs. And with the formal CUSMA review beginning July 1, trade uncertainty isn’t going away anytime soon.

For the housing market, this isn’t a direct price driver — it’s a confidence driver. TRREB estimates that more than 100,000 qualified buyers are sitting on the sidelines, and tariff-related uncertainty is a big reason they’re staying there. Every week the trade file dominates the news cycle is another week that segment of demand stays frozen.

Canada’s trade diversification effort has been faster than expected — recovering $11 billion of $18.5 billion in lost U.S. trade across 27 new partners — but with 20 percent of GDP still tied to American exports, the structural exposure remains.

Ontario Rents: The Fastest Decline in the Country

While tariffs and rates dominate the headlines, the rental market is undergoing its own quiet transformation.

Ontario asking rents fell 4.7 percent year-over-year — the steepest provincial decline in Canada, according to Rentals.ca’s March report. Nationally, asking rents hit $2,030 per month, a 33-month low, down 2.8 percent from a year ago. This marks the 16th consecutive month of year-over-year declines.

Several forces are converging. Immigration cuts — from 483,000 permanent residents in 2024 to 380,000 in 2026, with student visas slashed from 437,000 to 155,000 — have eased demand pressure. Meanwhile, CMHC data shows rental construction at near-record levels, with rental units under construction nearly doubling the 10-year average. Toronto posted its second-highest rental start volume ever.

The result is a rental market that’s rebalancing faster than most expected.

Where the GTA Market Sits Today

February’s numbers remain the latest data point: the average GTA selling price at $1,008,968, down 7.1 percent year-over-year but up 3.7 percent from January’s sub-$1 million dip. Sales volume came in at 3,868 transactions. Months of supply improved from 5.8 to 5.0 — still buyer’s market territory, but the direction is right.

In Mississauga, Zolo’s rolling average has softened to $948,753 with a median of 33 days on market. Brampton is showing more resilience at $887,000 with 309 February transactions — a 16 percent month-over-month jump.

New listings dropped 17.7 percent year-over-year, which continues to tighten the supply side even as demand stays cautious.

What This Means for Buyers

The rate environment just got more complicated — and that’s actually your cue to pay attention. Fixed rates are moving upward on bond yield pressure while variable rates hold steady, creating a narrowing window for both options. If you’ve been modeling your purchase at last month’s rates, it’s time to refresh that math.

The silver lining is that tariff uncertainty is keeping competition low. Homes are still selling at 97 percent of asking price, inventory is elevated, and negotiating power remains stronger than it’s been since 2019. Ontario housing starts hit their lowest level since 2014 last year, which means the supply you see now isn’t getting reinforced by a wave of new construction.

“This is the kind of market where preparation beats speed,” says Min. “The buyers who have their financing locked, their pre-approval current, and their search criteria clear are the ones finding value. The window doesn’t close all at once — but it does close.”

What This Means for Sellers

The tariff noise and rate movement create headwinds on buyer confidence, but they also create a pricing signal. Fixed rates are now at 3.84 percent — buyers are calculating their payments on that number, not the number from two weeks ago. Sellers who price into today’s borrowing reality rather than last month’s will connect with the buyers who are still actively in the market.

And there are real buyers in the market. Sales rose 25.5 percent month-over-month from January to February, and the seasonal spring pickup is underway. New listings are down significantly, which means less competition for well-presented homes.

The Ontario rent decline also creates an indirect opportunity. As rents fall — 4.7 percent year-over-year is the steepest drop in the country — some renters will start doing the purchase math. That creates a new buyer pool for entry-level and mid-range properties, particularly condos and townhomes.

What This Means for Tenants

For the first time in years, the leverage has shifted. Asking rents are at a 33-month national low. Vacancy rates have climbed to 3.1 percent. The immigration cuts that reduced demand and the record rental construction that’s adding supply are both working in your favour.

Ontario’s 2026 rent increase guideline is capped at 2.1 percent — the lowest in four years — which limits how much existing landlords can raise rents on current tenants. For new leases, landlords are increasingly willing to negotiate on price, concessions, and terms.

That said, well-located units near transit remain competitive, and non-traditional applicants — newcomers, self-employed individuals, students — still face screening challenges. Having representation in your corner still matters, particularly when navigating the application process.

What This Means for Landlords

The rental supply story cuts both ways. Record construction means more competition for tenants, and falling asking rents mean the days of pricing at 2023 peak levels are over. Landlords who compete on property quality, responsiveness, and fair pricing will outperform those relying on scarcity.

The rent guideline cap at 2.1 percent limits increases on existing tenants. In this environment, retention is the play — keeping a quality tenant at a fair rent beats a two-month vacancy followed by a lower market rate. For portfolio landlords, the current numbers favour stability over turnover.

“The landlords seeing the best results right now are the ones running their properties like a service,” says Min. “Maintain the unit, respond quickly, price realistically. The ones still testing peak-era rents are the ones sitting with vacancies.”

What to Watch

The Bank of Canada announces its next rate decision on March 18 — widely expected to be a third consecutive hold at 2.25 percent. But the bond market, not the overnight rate, is the number to watch. If the five-year yield stays above 3 percent, fixed rates will continue edging higher regardless of what the Bank of Canada does.

On the trade front, the CUSMA formal review begins July 1. Any resolution — or escalation — between now and then will directly influence buyer confidence and, by extension, spring market activity.

Ontario’s housing policy reset is also worth tracking. Bill 17’s development charge deferral — allowing developers to defer charges until closing rather than at building permit — could be the structural unlock that gets stalled projects moving again in the second half of the year.

The market rewards those who move with clarity, not those who wait for perfect conditions. The data is available, the rates are known, and the inventory is there. What happens next depends on what you do with it.
