Canada’s main interest rate is 2.25% as of the September 2026 central bank decision, unchanged for a sixth consecutive meeting. That pause means variable-rate mortgage holders are not facing an immediate repricing, while fixed-rate borrowers continue to track longer-term government bond yields rather than the overnight rate.
The Central Bank Interest Rate in 2026
Canada’s key interest rate is the target for overnight lending between financial institutions. It currently sits at 2.25%, down from 4.75% in June 2024 but above the 0.25% pandemic low from 2021. The central bank held the rate for the sixth straight decision as the economy recovered in Q2 and growth was projected at 2.5%. Core inflation is projected to return to 2% by early 2027.
Two external risks keep the central bank cautious. The Middle East conflict can push oil prices higher, and a new round of US tariffs could lift import costs. Available forecasts show the overnight rate remaining at 2.25% through the end of 2026, then falling to 2.00% by 2028.
How the Key Rate Transmits to Mortgage Interest Rates in Canada
Variable mortgage rates are generally linked to each lender’s prime rate, so changes in the overnight rate can affect borrowers’ payments. Fixed mortgage rates do not move step for step with the key rate because they also reflect longer-term government bond yields and lender spreads.
As a result, a central bank hold can leave fixed rates unchanged while variable rates remain aligned with lenders’ prime rates. Borrowers should compare the total cost of each option, including payment changes, renewal terms, and the risk of future rate increases.
Qualifying Rules: GDS, TDS, and Down Payment
Mortgage qualification has two ratios. The gross debt service (GDS) ratio caps housing costs at 32% of gross income; the total debt service (TDS) ratio caps all debt payments at 40%. If a household earns C$120,000 per year, monthly housing costs cannot exceed C$3,200 under GDS, assuming no other debts. Lenders use the lower of the two limits to set the maximum loan.
Down payment rules are tiered. A home priced below C$500,000 requires 5% down; a C$700,000 home requires 5% on the first C$500,000 and 10% on the remaining C$200,000, for C$45,000 total. Purchases over C$1,000,000 require 20% down. The down payment must be your own funds or a documented gift, not a loan, and it should be in your account for at least 90 days before underwriting.
Mortgage Default Insurance When Down Payment Is Below 20%
If your down payment is less than 20% of the purchase price, mortgage default insurance is generally required. The premium is applied to the mortgage amount and can range from 0.6% to 4.5%. A 5% down payment on a C$600,000 home creates a C$570,000 mortgage. The applicable insurance premium is then added to the principal, increasing the total loan balance.
The premium depends on the down payment and other characteristics of the mortgage. A down payment of 20% or more generally results in a conventional mortgage without default insurance.
Fixed vs Variable in 2026: A Borrower’s Break-Even Check
Run a simple break-even comparison before choosing a mortgage product. A variable mortgage may cost less if rates fall and remain lower, while a fixed mortgage provides more predictable payments. The value of each option depends on the expected path of the central bank rate, the lender’s pricing, and the borrower’s tolerance for payment changes.
However, if oil prices spike because of the Middle East conflict and inflation reaccelerates, the central bank may keep the rate at 2.25% for longer. A fixed rate then protects borrowers from variable repricing. Self-employed borrowers may face stricter down payment rules, so a mortgage broker can compare lenders that accept alternative income documents.
What Borrowers Should Do Now
- Confirm your GDS 32% and TDS 40% ratios using your current income documents and pay stubs.
- Compare rate holds from multiple lenders or a broker, because a rate hold can freeze a fixed rate while you shop.
- Keep your down payment in your own account for 90 days so underwriting does not flag it as a loan.
- Compare the total insured mortgage cost, because a lower contract rate with a higher insurance premium can cost more than a higher rate with 20% down.
2027 and 2028 Outlook
Available projections show the policy rate holding at 2.25% through the fourth quarter of 2026, then dropping to 2.00% by 2028. The central bank expects inflation to reach its 2% target by early 2027, which supports a modest cut path. The largest risk to that path is a Middle East-driven oil shock or new US tariffs that raise import prices. If core inflation moves above the 2% target, the central bank could hold Canada’s main interest rate longer than projected, keeping variable mortgage rates higher than they would be after a cut.
