How U.S. Interest Rates Are Reshaping the GTA Housing Market

The trade war with the United States and the Federal Reserve's latest interest-rate hike have added another layer of uncertainty to the GTA real estate market. The honest truth is that Toronto's housing story is no longer being shaped by local supply and demand alone. Decisions made in Washington, movements in international bond markets and geopolitical events affecting oil prices can influence Canadian mortgage rates within days.

Developments outside Canada can affect your purchasing power, carrying costs and negotiating position before their full impact appears in Toronto's monthly housing statistics. You may not follow the Federal Reserve or the bond market every day, but if you are planning to buy, sell or renew a mortgage, these developments can directly affect your options.

The Federal Reserve raised its benchmark interest rate by a quarter percentage point to a range of 3.75%-4%, marking its first increase since 2023. The Fed's unanimous decision suggests that the move was driven primarily by inflationary pressure rather than political considerations. September's inflation report may be even less encouraging because it will more fully reflect the rise in oil prices associated with the conflict with Iran.

For GTA homeowners and buyers, the main takeaway is that this may not be a one-time increase. Fed funds futures are already indicating a high probability of another hike by December, while some economists believe markets continue to underestimate how long interest rates could remain elevated. That does not guarantee another increase, but buyers should not build their plans around the assumption that mortgage rates will quickly return to previous lows.

A U.S. interest-rate decision does not stop at the Canadian border. Canadian five-year government bond yields often move closely with U.S. Treasury yields because international investors view the two markets as competing places to invest their money. Canadian fixed mortgage rates are then priced largely from the five-year Government of Canada bond yield. When U.S. yields rise because of inflation concerns, Canadian fixed rates can follow even if the Bank of Canada leaves its own policy rate unchanged.

That is what we are seeing now. The Canadian five-year bond yield jumped approximately 16 basis points in a single day, reaching its highest level since 2024. It was also about one percentage point higher than before the U.S.-Israel conflict with Iran disrupted global energy markets in late February. Canadian lenders began repricing their fixed mortgage rates almost immediately.

For an individual buyer, the financial effect can be meaningful. On a $500,000 mortgage, the difference between a variable rate near 3.68% and a fixed rate near 4.59% is approximately $250 per month. The higher qualifying rate could also reduce the borrowing capacity of a household earning $100,000 by roughly $30,000 to $40,000, depending on its debts, property taxes, heating expenses, condo fees and other housing costs.

That difference is not merely theoretical. It could determine whether a buyer can afford a detached home or needs to consider a townhouse. It could affect whether a family can remain within its preferred Markham school district or needs to expand its search toward Newmarket or East Gwillimbury. It may even determine whether someone can purchase a resale property today or has enough financing to complete a pre-construction purchase later.

This is why I regularly remind buyers that a mortgage pre-approval is not a permanent promise. In a fast-moving bond market, the rate and purchasing power behind that approval can change before the stated expiry date. Before preparing an offer, buyers should confirm the protected rate, expiry date and maximum qualifying amount with their mortgage professional. I would rather have a client discover a change before making an offer than after becoming committed to a purchase.

Variable-rate borrowers also need to pay close attention. Over the past year or two, many Canadians chose variable-rate mortgages because they offered a meaningful discount compared with fixed rates and were expected to become even cheaper as interest rates declined. The Fed's latest move now challenges that assumption. If inflation remains elevated, the Bank of Canada may have to delay further rate cuts. It would postpone the payment relief many borrowers are expecting. In a more severe inflationary scenario, the Bank of Canada could raise its policy rate, which would directly increase variable mortgage rates and borrowers' monthly payments.

If this hiking cycle lasts longer than expected, the most exposed group may not be today's buyers, who can make a new decision using current information. It may be borrowers who recently selected variable rates because they expected rates to continue falling. If you are in that position, I suggest calculating what your payment or remaining amortization would look like after one or two additional increases. Your mortgage should remain manageable even if the most optimistic forecast proves wrong.

These international pressures are arriving when the GTA market is already fragile. August's average selling price fell below the psychologically important $1 million level to approximately $990,000. Although the average remains above January's low, this is the second time this year that it has fallen below $1 million, and the broader seasonal trend has weakened.

One encouraging development, however, is that fewer homeowners appear willing to list their properties at today's prices. When sellers who are not under pressure choose to rent their homes or postpone moving, the number of new listings begins to decline. This limits available supply and may help the market stabilize, particularly if buyer demand remains steady or begins to improve. It does not mean a recovery has already started, but tighter supply is often one of the conditions that helps prices find a floor.

I am seeing this in my own business. Several homeowners have converted their listings into rentals or decided not to move because the price available in the current market was lower than they were prepared to accept. Owners who purchased near the peak are often waiting for prices to recover, while some investors are delaying a sale because the current market value may not cover their outstanding mortgage, transaction costs and original investment.

This reduction in available supply may help the market stabilize, but it does not mean every property that remains listed will sell easily. Buyers are still highly price-sensitive and generally unwilling to meet an unrealistic asking price. Well-located homes with strong schools, practical living space and appropriate pricing can still generate serious interest. A comparable home launched above market value, however, may sit for weeks and eventually sell for less than it might have achieved with a realistic pricing strategy from the beginning.

The sales-to-new-listings ratio also needs to be interpreted carefully. An improving ratio may appear to signal a recovering market, but that is not necessarily the case. If more transactions occur only because sellers are accepting lower offers, the improvement reflects greater seller motivation rather than stronger pricing power. Homes are still trading, so the market has liquidity, but transactions are increasingly taking place at prices buyers are prepared to support rather than prices sellers hoped to receive.

Buyers and sellers often ask me whether the market has reached the bottom or whether prices will improve next year. The reality is that the GTA housing recovery is likely to be K-shaped, meaning different market segments will move in different directions and recover at different speeds. Certain property types and neighbourhoods may stabilize or begin improving while others continue to face downward pressure.

That is why I caution clients against making decisions based only on the GTA-wide average price. That single number combines downtown condominiums, suburban townhouses and luxury detached homes, even though these segments are behaving very differently.

Condominiums remain particularly exposed because of their high level of investor ownership, negative cash flow and the backlog of pre-construction units approaching completion. Many investors purchased with the expectation that rising values would offset weak monthly cash flow. When financing costs rise and price growth disappears, that strategy becomes much harder to sustain.

By comparison, fairly priced freehold homes in established family neighbourhoods generally benefit from more durable end-user demand, especially when they offer strong schools, practical layouts and convenient access to employment. Families who need more space may postpone a move, but they cannot always delay it indefinitely. That underlying need can help certain freehold segments stabilize before investor-dependent markets do.

Even within the same city, one neighbourhood may remain relatively stable while another experiences meaningful price reductions. A desirable school boundary, a functional floor plan or convenient transit access can make a significant difference. This is why the question is no longer simply whether the GTA market has reached the bottom. The more useful question is which property type, price range and neighbourhood is beginning to stabilize—and whether that particular market fits your financial position and long-term plans.

From my perspective, trying to predict the exact bottom is less useful than understanding the conditions developing around it. Lower borrowing capacity remains a challenge, but a reduction in new listings can limit supply. Buyers still have negotiating leverage, but desirable properties do not all behave like the GTA average. Some segments may continue declining while others quietly begin to recover.

The right decision therefore depends on your circumstances. A buyer planning to hold a well-chosen family home for many years faces a different level of risk from an investor purchasing a negative-cash-flow condominium and relying on short-term appreciation. A seller who must relocate has different priorities from an owner who can rent the property and wait.

In this market, I would not advise buyers or sellers to freeze while waiting for someone to announce that the bottom has arrived. Instead, understand your financing, study the specific segment in which you are buying or selling and make the decision around your own timeline. The GTA will not recover everywhere at once, and the best opportunities are likely to appear before the overall average price confirms that conditions have improved.
