Canadian mortgage rates are quoted as nominal annual rates with semi-annual compounding. The true monthly rate is (1 + annual/2)^(1/6) − 1. The average 5-year fixed rate was about 5.1% in September 2026.
A Canadian mortgage has a term (typically 2–5 years, during which the rate is fixed) and an amortization period (usually 25–30 years over which the loan is fully repaid). This calculator amortizes over the full period.
Below 20% down, borrowers must buy default insurance (CMHC, Sagen or Canada Guaranty) at a reference premium of roughly 2.8%–4% of the loan, which can be added to the principal. Frequencies include monthly, semi-monthly, bi-weekly, weekly and their accelerated versions.
· True monthly rate = (1 + annual rate ÷ 2)^(1/6) − 1
· Down 5%–9.99%: premium ≈4.0%; 10%–14.99%: ≈3.1%; 15%–19.99%: ≈2.8%
· Amortization is usually 25–30 years (25-year cap below 20% down)
· Accelerated bi-weekly/weekly payments significantly cut total interest
Example: price C$600,000, 20% down, 5.1% rate, 25-year amortization → loan C$480,000, payment ≈ C$2,819/month.
Semi-annual compounding：Canada's statutory quoting convention. The true monthly rate is (1+annual/2)^(1/6)−1; dividing by 12 understates the cost.
CMHC default insurance：Mandatory below 20% down; premium roughly 2.8%-4% of the loan, paid upfront or added to principal.

Regulators require mortgage rates to be quoted as nominal annual rates with semi-annual compounding. Dividing by 12 would understate the true monthly rate, so the effective monthly rate must be derived first.
Below 20% down, lenders require mortgage default insurance (e.g. CMHC) that protects them if you default. The premium is a percentage of the loan and can be paid upfront or added to the mortgage.
The term is how long your rate is locked (e.g. 2 or 5 years), after which you renew. Amortization is the total time to repay the loan in full, usually 25–30 years.
Accelerated bi-weekly pays half the monthly payment 26 times a year, effectively one extra monthly payment annually — typically shortening a 25-year amortization by 2–4 years and saving tens of thousands in interest.
Put down 20% or more. Below 20%, expect the insurance premium and often a slightly higher rate.
