The short answer

Renew if your current lender is competitive and the contract fits your next few years. Transfer if another lender offers materially better pricing or contract terms without needing extra funds. Refinance if you need new money, debt consolidation, equity access, or a materially different structure.

A lower payment is not the same as a lower total cost. Compare the same remaining amortization and time period, then account for the costs you actually pay to move.

Renew, transfer, and refinance compared

The right path depends on whether you are only replacing the term, moving the balance, or changing the mortgage itself. The more you change, the more underwriting and closing work you should expect.

What does switching mortgage lenders cost?

At maturity, confirm the payout date and any discharge, assignment, registration, legal, appraisal or administration charges. Ask the receiving lender which costs it covers, how reimbursement works and whether an incentive must be repaid if you leave early. Do not assume a switch is free.

If your mortgage has a collateral charge, ask how every debt secured by that charge will be repaid or transferred. A linked line of credit can affect the transaction even if you only want to move the mortgage.

Is a 0.25-percentage-point lower rate worth switching for?

It depends on the balance, remaining amortization, term, costs and mortgage features. This illustration compares a $400,000 balance with 20 years remaining, monthly payments, Canadian semi-annual compounding and two five-year fixed-rate offers. These are example rates, not available offers. Fees are paid separately, not added to the mortgage.

  • The payment is about $52.60 lower per month. That is cash-flow relief, not the full interest saving.
  • Interest is about $4,674 lower over five years. With an illustrative $1,500 net upfront switching cost, the interest benefit after that cost is about $3,174.
  • At $52.60 a month, the payment savings recover the $1,500 upfront cash outlay in about 29 months. This cash-flow payback calculation is different from the interest comparison.
  • A three-year and five-year offer need a shared comparison period. A rate after the shorter term expires is unknown; do not assume the lower initial rate wins over five years.
Illustration: staying at 4.50% versus switching at 4.25%
MeasureStay: 4.50%Switch: 4.25%
Monthly principal and interest$2,521.62$2,469.02
Interest over 60 months, rounded$81,842$77,168
Balance after 60 months, rounded$330,545$329,027

What to compare beyond the rate

A lower rate can still be the wrong mortgage if the penalty formula, prepayment rules, collateral charge, portability, or renewal flexibility creates a future problem.

Ask for the APR, the standard or collateral charge details, prepayment privileges, porting rules and the penalty formula before you choose. Compare the same term and eligibility conditions.

  • Penalty formula: especially important on fixed-rate terms.
  • Prepayment privileges: useful if cash flow may improve.
  • Portability: useful if you may move before term end.
  • Collateral charge: may affect switching friction later.

Qualification and timing

A simple renewal with the existing lender may not require the same qualification work as switching. A transfer usually needs income, property, and credit review. A refinance normally needs full underwriting because the mortgage is changing.

Start early because document collection, appraisal needs, discharge statements, and legal work can take time. If the maturity date is close, the path with the best headline rate may not be the path that can close cleanly.
