The Bank of Canada moved its rate. Here is how that can reach you.

When the Bank of Canada changes its policy rate, banks reprice loans and deposits. The Bank says changes in its rate lead to similar changes in short-term rates, including the prime rate on which banks base variable-rate mortgages, and can also affect long-term rates, especially if the change is expected to last. In the 2022 tightening, the Governor said, the average five-year variable mortgage rate rose from 1.5% to 5.9% between January 2022 and January 2023, and the average five-year fixed rate from 2.8% to 5.1%.

Limits

The Bank says it does not set mortgage rates but has some impact on them; a lender's funding cost makes up most of a mortgage rate, and fixed rates also respond to interest rates abroad. It is not automatic: early in the pandemic the Bank cut its rate, but rates on new mortgages did not decline much and some went up. Posted rates are only a guide to what borrowers pay: a 2020 Bank staff working paper says less than 1% of borrowers pay the standard posted rate. This edge does not claim any particular size of pass-through.

Timing

The Bank says that when it raises its rate it immediately costs banks more to borrow, and that they respond by raising their rates for loans and deposits. It gives no number of days for mortgages. It says monetary policy takes up to two years to have its full effect.

These include the prime rate, which is used by the banks as a basis for pricing variable-rate mortgages. A policy-rate change can also affect long-term interest rates, especially if people expect that change to be long-lasting.

Mortgage debt-servicing costs are a key channel through which the policy rate reaches households, Bank of Canada staff say. They add that the timing of the pass-through depends greatly on the structure of household debt: a tightening reaches household finances more quickly when more households hold variable-payment mortgages, and may take longer when long-term fixed contracts make up more of the debt.

Limits

The staff note gives its authors' views, not official Bank policy. It describes mortgage payment pass-through, not house prices.

Timing

The Bank says monetary policy as a whole takes up to two years to have its full effect, but this channel can run longer. Borrowers with variable rates and those looking for a new mortgage feel a rise first, and others as they renew: Bank of Canada staff said in 2024 that the impact of the tightening that began in early 2022 would continue to gradually materialize over the next few years.

Bounajm and McWhirter, Modelling Canadian mortgage debt and payments in a semi-structural model, Bank of Canada Staff Analytical Note 2024-1Looking ahead, the magnitude and timing of monetary policy pass-through will depend greatly on the structure of household debt. For example, if the proportion of households holding variable-payment mortgages increases, then monetary tightening will pass through to household finances more quickly. And if long-term fixed contracts grow as a share of outstanding mortgage debt, rate increases may take longer to have their full impact on consumer spending.

Nearly a year later, people renewing their home loans are also facing higher interest costs.

The Bank of Canada says higher interest costs discourage borrowing, which might mean fewer people take out a mortgage to buy a home. CMHC said in July 2026 that housing market activity that year had so far been weaker than expected, particularly in sales and prices, and that this reflected slower population growth, ongoing economic uncertainty, high mortgage rates and slow income growth.

Limits

CMHC lists four reasons together and does not separate the part due to mortgage rates; it describes 2026 up to June and names sales and prices, not housing starts. Neither source gives a measured effect size or a lag, and Northline has not estimated one.

Timing

The record gives no lag for this link.

Higher borrowing costs discourage borrowing, and rate-sensitive sectors such as housing often slow first, according to the Bank of Canada. The Bank describes the channel in general terms; it does not estimate the effect on any one city or on prices versus activity.

Limits

The Bank describes the channel in general terms and gives no size. Its account is about the cost of new borrowing; it does not separate the effect of higher payments on existing mortgages. City responses may differ (price levels, tenure, new-build share); that is Northline's expectation, not a finding of the source.

Timing

The Bank says sectors sensitive to interest rates, like housing, are often the first to slow, and that monetary policy takes up to two years to have its full effect.

That might mean fewer people take out a mortgage to buy a home. They might delay buying a new car because the loan is more expensive. Or they might put off that kitchen renovation or family vacation. That's why sectors that are sensitive to interest rates, like housing, are often the first to slow when we raise interest rates

Higher mortgage payments can reduce the discretionary income available for spending, according to a Bank of Canada staff note. The Bank's Governor has said that when rates rise, households with mortgages have less money to buy other things.

Limits

Magnitude and timing depend on mortgage structure; not quantified here. The staff note adds that borrowers who can lower their principal payments may not have to cut discretionary spending. Spending also depends on income and other forces, so it can keep growing while mortgage costs rise.

Timing

The record gives no lag for this link.
