Short answer: The five costliest renewal mistakes are signing your lender's first offer without comparing, starting too late, ignoring penalty and portability clauses in the new term, renewing into the same structure when your life has changed, and assuming you cannot switch lenders. Start about four months early and compare real options, and renewal becomes a savings opportunity instead of a chore.
Banks mail or message a renewal offer hoping you will sign in one click. That offer is rarely the bank's best rate, and it is never compared against the rest of the market. Countless Canadians pay more for five years because signing was easier than asking. Always compare your offer against at least the wider lender market before you sign anything.
Many lenders open rate holds up to 120 days before your term ends. Starting early lets you lock a rate, compare lenders, and complete a transfer calmly. Starting in the last two weeks removes your leverage: there is no time to switch, so your current lender has no reason to compete. Put a reminder four months before your maturity date, or note your renewal date when you first get your mortgage.
Rate is only one line of the contract. Penalty calculations, portability, prepayment privileges, and whether your mortgage is a collateral charge all shape your real costs if life changes. A slightly higher rate with a fair penalty can be thousands cheaper over the term than a rock-bottom rate with a punitive one. Read the terms, or have someone explain them, before signing.
Your life at renewal is not your life five years ago. Maybe you can afford faster payments and a shorter amortization. Maybe you should consolidate a stubborn debt, extend amortization briefly to survive a tight year, or switch from fixed to variable or back. Renewal is the penalty-free moment to restructure. Rolling the old structure forward without a review wastes that moment.
On a straight renewal transfer, where the amount and amortization do not increase, federal rules allow you to switch lenders without reapplying the stress test, and the new lender commonly covers transfer costs. In plain terms: switching is usually easier and cheaper than people fear, and your current lender knows it. The only requirement is time, which is why Mistake 2 matters so much.
Renewal advice usually assumes you wait for maturity, but occasionally paying a penalty to restructure early saves more than it costs, for example when consolidating heavy high-interest debt or escaping a very unfavourable penalty structure before it grows. This is a math question, never a guess: the penalty, the new costs, and the savings all need exact figures. If your situation feels urgent mid-term, ask for a break-versus-wait analysis rather than assuming you are locked in until the renewal date arrives.
