What a mortgage renewal actually is
Your mortgage has two clocks: the amortization (the ~25-year runway to fully pay it off) and the term (the shorter contract — often 3 or 5 years — that fixes your rate). A renewal happens when the term ends and the balance still has years left to run. You're not paying anything off early and you're not changing the loan — you're simply signing a new term at a new rate on the same outstanding balance. Because nothing is being broken, there's no penalty to renew, and the paperwork is light.
The catch is what most people do next: they sign the renewal letter their current lender mails them. That offered rate is frequently not the lender's best — it's a posted or lightly discounted rate, betting on your convenience. You are under no obligation to accept it. Federally regulated lenders must send your renewal statement at least 21 days before your term ends (FCAC: renewing your mortgage), but many lenders will hold a rate for up to about 120 days before maturity, so start comparing four to six months out.
