Payment Frequency

Payment frequency is how often you make mortgage payments — typically monthly, semi-monthly, bi-weekly, or weekly. In Canada, the lender sets the available options, and your choice changes the size of each payment and the pace at which the balance is paid down, even when the interest rate and amortization period stay the same.

How Canadian payment frequencies work

Canadian mortgages normally quote interest compounded semi-annually, not in advance, and lenders convert that rate and your chosen schedule into each payment amount. The common choices are:

Monthly — 12 payments per year.
Semi-monthly — 24 payments per year, usually on the 1st and 15th, each about half the monthly amount.
Bi-weekly — 26 payments per year.
Weekly — 52 payments per year.

Bi-weekly and weekly come in two forms. A regular schedule is calculated so the annual total matches the monthly total. An accelerated schedule is calculated by dividing the monthly payment, which produces 26 half-payments — the equivalent of 13 full monthly payments a year. That extra amount goes directly to principal, which is why accelerated payments shorten the amortization and reduce total interest.

Why it matters to a borrower

More frequent payments mean slightly less interest accrues between them, though the difference is modest on a regular schedule. The larger gain comes from acceleration, an automatic form of prepayment that works without a separate lump sum. The trade-off is cash flow: weekly and bi-weekly debits must line up with income and with pre-authorized debit dates, and a missed payment can lead to arrears and credit consequences.

What to check before switching

Ask whether frequency changes carry a fee, whether your mortgage is closed or open, and whether your prepayment privilege already permits the extra amount. Raising payment frequency does not change your interest rate or your lender's qualification rules, including the federal mortgage stress test; it only changes repayment speed. To estimate the difference, run the biweekly vs monthly mortgage calculator, and read the full payment frequency guide.

Frequently asked questions

Does paying bi-weekly instead of monthly save interest in Canada?

Yes, if the schedule is accelerated. Accelerated bi-weekly payments are calculated by halving the monthly payment, producing 26 payments a year — the equivalent of 13 monthly payments instead of 12. The extra amount reduces principal sooner, so less interest accrues over the amortization. A regular bi-weekly schedule, calculated to match the annual monthly total, saves only a small amount.

Can I change my mortgage payment frequency later?

Most Canadian lenders allow a frequency change during the term, though some charge a fee and others limit how often you can switch. Changes usually take effect on a payment date. Review your mortgage commitment or contact your lender to confirm the rules, any fees, and whether an accelerated option is available for your mortgage.

Is weekly better than bi-weekly for a mortgage?

Neither is universally better. Both can be run on a regular or accelerated basis, and the accelerated versions produce a similar interest saving because they add roughly the same extra payment each year. Weekly may suit weekly paycheques; bi-weekly may suit bi-weekly pay. Choose based on cash flow and debit timing rather than a rule of thumb.
