Cutting interest rates does not make homes more affordable. In a staff paper published on 20 August 2026, Bank of Canada researchers found that resales jump almost immediately after a cut and house prices rise and stay up, while housing starts only begin to respond about two years later.
A rate cut is not a discount on a house. That is the finding of a staff paper the Bank of Canada published on 20 August 2026, which traced what happens to resales, housing starts and house prices in Canada after interest rates fall.
Buyers move within weeks. Builders move within years. Prices move in between, and they stay up.
What did the Bank of Canada find?
The paper, How Do Interest Rates Spur the Housing Market: Exploring Nonlinear Effects, examined how a surprise change in interest rates feeds through to housing demand, supply and prices, and whether the answer depends on the state of the labour market.
Three results matter to anybody buying a home. Resales surge almost straight away after a cut, and the larger effects arrive 18 to 24 months later. Housing starts only begin to pick up around two years after the cut. House prices rise, and the increase persists.
Put together, the researchers concluded that rate cuts move the housing market, especially when unemployment is low, but they do not improve the imbalance between supply and demand.
Why do prices move before supply does?
Because buying is a decision and building is a project.
A cut changes what a buyer qualifies for and what a payment costs in the same month lenders reprice. Nothing new has been built yet, so the same homes are chased with more borrowing capacity, and the price is where that shows up.
A builder cannot respond at that speed. Land, financing, approvals, servicing and trades all sit between a lower rate and a finished home, and the two year gap the paper measures is the size of that queue. By the time the extra supply arrives, the price increase has already happened.
Does the job market change the answer?
Yes, and this is the part worth remembering.
The paper found the effect of lower rates is amplified when unemployment is low. When unemployment is high, a rate cut produced effectively no change in housing demand, and the price response was far more muted.
So a cut that lands while people feel secure in their jobs is the one that moves prices most. A cut that arrives because the economy is struggling does much less, which is worth understanding before reading any single decision as good news for affordability.
What does this mean if you are waiting to buy in Toronto?
The Bank held its policy rate at 2.25 per cent on 15 July and the next scheduled decision is 2 September.
If the plan is to wait for a cut and then buy the same home for less, this research points the other way. Cheaper borrowing turns up in prices before it turns up in the number of homes available.
Waiting can still be the right call. Saving a larger deposit, clearing debt or waiting out a job change are all real reasons. Hoping a house gets cheaper because money got cheaper is not one the evidence supports.
Two practical notes. Fixed mortgage quotes do not follow the policy rate directly, they follow bond yields, which is why fixed rates can rise while the Bank sits still. And it is worth knowing what you can carry at today rates rather than at the rate you hope to see, which is what our affordability calculator is for. When you are ready to look, start here.
Is this the Bank of Canada official position?
No. Staff papers are research the Bank publishes to inform discussion, and this one carries the standard note that the views in it are the authors own and may differ from official Bank of Canada positions. It is evidence about how the housing market has behaved after past rate changes, not a forecast of what the Governing Council will decide on 2 September.
