Canada’s housing problem has reached an uncomfortable stage: making homes cheaper is desirable for people trying to enter the market, but falling prices can also weaken household wealth, construction and economic activity. Bank of Canada Senior Deputy Governor Carolyn Rogers captured that tension in unusually direct language during an October 1 speech in Victoria, saying the situation feels “a bit like a trap.”

The message was not that interest rates are irrelevant. Borrowing costs have enormous influence over mortgages, home sales and prices. Instead, the Bank is arguing that rates cannot repair years of housing shortages, planning constraints and an economy increasingly tied to residential real estate. With affordability still strained for millions of households, the central bank is drawing a sharper line between what monetary policy can influence and what it simply cannot fix.

The Bank’s “Trap” Goes Far Beyond Expensive Homes

Rogers’ description of a trap gets at one of the most difficult features of Canada’s housing problem. When home prices rise rapidly, existing owners can accumulate substantial paper wealth, but prospective buyers need larger down payments and mortgages. Renters can also face greater pressure as people remain in rental housing longer. When prices fall, affordability can improve for buyers, but homeowners lose equity, consumer confidence can weaken and developers may become less willing to launch projects.

That tension has become visible in household budgets. Statistics Canada reported in September that, based on its 2024 Canadian Housing Survey, 23.2% of households were spending at least 30% of their income on shelter costs, up from 22% in 2022. The pressure was especially pronounced among renters, with 33.7% living in housing classified as unaffordable under that measure. Among homeowners carrying a mortgage, 26.1% were in unaffordable housing, up from 23.6% two years earlier. Affordability, in other words, is no longer just about getting a down payment together.

Housing Has Become Deeply Embedded in Canada’s Economy

The Bank’s concern is partly about scale. Rogers noted that roughly half of Canadian bank lending is connected to residential real estate. Mortgages are also the largest component of household borrowing, while home equity represents a major source of household net worth. That means housing prices can influence much more than the ability to buy a property. They affect borrowing capacity, consumer spending, bank balance sheets and confidence throughout the economy.

Canada’s investment mix illustrates how important housing has become. Rogers pointed out that residential investment represented 4.3% of GDP in 2000, compared with 8.3% for business investment in areas such as machinery, equipment and innovation. She said that relationship has since reversed, with Canada now investing more in residential housing than those productivity-enhancing business assets. That helps explain why a straightforward price correction is not necessarily painless. Housing has become simultaneously shelter, an investment vehicle, collateral for borrowing and a major source of economic activity, making affordability policy unusually complicated.

Low Interest Rates Helped Fuel the Boom—but They Were Not Acting Alone

The Bank of Canada is not denying its role in the extraordinary housing boom that followed the pandemic. Rogers acknowledged that low interest rates contributed to higher prices because cheaper borrowing allows households to qualify for larger mortgages and increases demand. During the pandemic period, emergency monetary policy and government support arrived at the same time as a desire for more living space, limited housing supply and, later, rapid population growth. Rogers noted that Canada’s average home price increased roughly 50% over a two-year period.

But treating low rates as the sole explanation misses the supply side of the equation. The Bank points to zoning restrictions, infrastructure limitations, construction constraints, population growth and incentives to view housing as an investment as additional forces affecting prices. Those factors help explain why housing can react so powerfully when credit becomes cheaper. If considerably more buyers can borrow but the stock of available housing cannot expand at a comparable speed, more purchasing power ends up competing for essentially the same pool of homes. Lower financing costs can therefore improve affordability temporarily for an individual borrower while simultaneously creating upward pressure on market prices.

Cutting Rates Can Make Mortgages Cheaper—and Homes More Expensive

The contradiction is particularly important now that the Bank’s policy rate sits at 2.25%, well below the levels reached during the inflation-fighting cycle. A lower central-bank rate can eventually reduce some borrowing costs, giving households greater purchasing capacity. That sounds like an affordability solution. The problem is what happens when thousands of potential buyers receive that additional purchasing power while housing construction responds much more slowly.

Bank of Canada researchers examined exactly that issue in a 2026 analytical paper. Their findings indicated that lower interest rates tend to boost resale activity quickly, while the increase in housing starts comes later. House prices, meanwhile, can rise persistently. The effects were particularly strong when unemployment was low. The implication is important: demand can react considerably faster than supply. Monetary easing can certainly reduce financing costs, but it cannot guarantee that the savings stay with buyers rather than being capitalized into higher property prices. That is why Rogers described the policy rate as too blunt an instrument to target housing affordability directly.

Higher Rates Create the Opposite Problem for Buyers and Owners

Raising interest rates can restrain housing demand and take pressure off prices, but it does so by making credit more expensive. New buyers may qualify for smaller mortgages even if asking prices fall. Existing homeowners can face substantially higher payments when mortgages renew. Meanwhile, developers face higher financing costs of their own, potentially making it harder to launch projects precisely when additional housing supply is needed.

The mortgage-renewal experience demonstrates the trade-off. In its May 2026 Financial Stability Report, the Bank estimated that a group representing about 12% of outstanding mortgages—primarily longer-term fixed-payment loans taken out when rates were exceptionally low—would renew over the subsequent 12 months and experience an average payment increase of roughly 15%. Most households had nevertheless absorbed earlier increases without widespread defaults. Canada’s mortgage stress test helped: the Bank reported that more than 90% of borrowers who had recently renewed did so at rates below the rates at which they originally qualified. The regulation strengthened resilience, but as Rogers emphasized, resilience and affordability are not the same thing.

Renters Are Caught in Their Own Version of the Affordability Squeeze

The ownership market receives much of the attention, but roughly one-third of Canadians rent. Bank of Canada research published in September found that national asking rents had increased by more than 20% since 2021. Much of the increase occurred from late 2021 through late 2023, when growth in the number of households seeking rental accommodation outpaced additions to rental supply. Rising financing costs during 2022 and 2023 also contributed.

Conditions have improved in some markets since then. Population growth has slowed, rental construction has been strong and asking rents have declined in places including Toronto and Vancouver. Yet those changes do not instantly reset what tenants pay. The Bank estimates national rental-unit turnover at about 13% annually, meaning changes in advertised rents gradually work their way into the average rents captured by the Consumer Price Index. Statistics Canada’s housing survey also shows how deep the pressure became: 33.7% of renters were spending at least 30% of income on shelter in 2024, while dissatisfaction with affordability among market renters stood at 28.9%.

Falling Home Prices Have Not Automatically Restored Affordability

Canada has already experienced part of the price adjustment that prospective buyers once hoped would solve the problem. The Bank’s 2026 Financial Stability Report estimated that the price of a typical Canadian home had fallen about 20% from its 2022 peak as of the report’s publication. More recent CREA figures showed the national MLS Home Price Index down 3% year over year in August 2026. Yet affordability remains a serious concern.

One reason is that purchase price is only part of the calculation. The national average sale price was still $668,219 in August, according to CREA, while mortgage rates remained far above the exceptionally cheap borrowing available during the pandemic. Income growth, property taxes, insurance, maintenance and other ownership costs matter as well. Statistics Canada found that 27.9% of households reported experiencing financial difficulty because rent or mortgage payments had increased during the 12 months covered by its 2024 housing survey. A softer market can therefore improve the negotiating position of buyers without making ownership realistically attainable for every household that was previously priced out.

Canada Is Still Building Far Less Housing Than CMHC Says Is Needed

The scale of the supply challenge helps explain why the Bank is reluctant to frame interest rates as a housing solution. CMHC’s September 2026 Housing Supply Report estimated that Canada needs roughly 417,000 to 469,000 housing starts annually to restore affordability to pre-pandemic levels by 2036. Its current projections leave an annual supply gap of approximately 187,000 to 238,000 homes over the next decade.

There is also a mismatch inside the construction numbers. Rental construction has performed relatively well in several major markets, helping vacancy conditions and rent growth move toward greater balance. Ownership-oriented construction has been much weaker, particularly condominiums and other projects that depend on presales. CMHC warns that slowing construction during a period of softer demand could create another shortage when demand eventually strengthens. Toronto alone still needs annual starts to rise by at least 50% over the coming decade under CMHC’s affordability scenario. Interest rates can alter whether a development is financially attractive, but they cannot supply serviced land, approve a zoning change, install infrastructure or issue a municipal building permit.

The Emerging Answer Is a Policy Mix Rather Than One Big Fix

Rogers’ conclusion was deliberately broader than monetary policy. Restoring affordability, she argued, requires more housing supply, improved planning and infrastructure, regulation that preserves financial resilience and incentives that do not simply add demand to an already constrained market. That does not mean every supply policy has the same impact or that construction can expand overnight. Housing projects often require years to move from land acquisition and approval to completed homes.

Research increasingly points to the importance of making the supply side more responsive. CMHC modelling published in 2026 estimated that bringing Canadian housing-supply responsiveness closer to U.S. levels could have produced almost 30% more housing starts and prices nearly 10% lower in its modelled scenario. Separate research has highlighted the role of zoning, permitting and land-use restrictions, while academic work finds that upzoning can increase housing production but often takes years to deliver measurable results. The Bank’s role remains narrower: preserve low and predictable inflation and account for housing when setting policy. In Rogers’ formulation, housing should influence interest-rate decisions, but house prices themselves should not become the central bank’s target.
