Refinancing means ending your current mortgage early and starting a new one. The new mortgage might have a different rate, balance, or term.
Because you're ending the old contract early, the lender usually charges a penalty. That penalty plays a big role in whether refinancing is worth it.
To lower their rate
Some homeowners explore this when rates drop noticeably from when they signed.
To consolidate higher-interest debt
Rolling things like credit cards into a mortgage can lower monthly payments — but the long-term math should always be reviewed.
To access home equity
In Canada, refinancing typically allows up to 80% of the home's appraised value, often used for renovations or other goals.
Most penalties fall into one of two categories. The right one for you depends on your contract.
3-month interest
Common with variable-rate mortgages. Roughly three months of interest on your current balance.
IRD (Interest Rate Differential)
Common with fixed-rate mortgages. The amount can vary widely depending on how the lender calculates it.
Worth knowing
Penalties can vary a lot between lenders. A licensed broker can review your contract and give you the actual number before you make a decision.
The general idea: compare what you might save in interest against the penalty and any fees.
If the difference is meaningful, refinancing may be worth a closer look. If it's small or unclear, waiting until renewal — when there's no penalty — is often the simpler path.
Quick example
On a typical refinance, savings only really show up when the new rate is meaningfully lower and the penalty isn't too high. A broker can run your real numbers so you're not guessing.
In Canada, refinances are generally capped at 80% of the home's appraised value.
Home value
Based on a current appraisal — not online estimates.
Maximum new mortgage
Usually up to 80% of the appraised value.
Cash available
Roughly the new mortgage minus your current balance, penalty, and fees.
Penalty is bigger than the savings
Sometimes waiting until renewal makes more sense.
You may be moving soon
Most refinances need time to pay off — moving too quickly can wipe out the benefit.
Borrowing for short-term spending
Stretching short-term costs over a long mortgage can quietly add up.
Chasing a very small rate change
If the savings are tiny, the math often doesn't work out.
