Can I switch my mortgage before renewal?
Yes — you can leave any time. The question is whether the penalty leaves you better off, and most of the time the honest answer is no. Here is how to work it out rather than guess.
- You can break a mortgage any time; it is a cost question, not a permission question
- The penalty is usually the higher of three months' interest or the IRD
- Your lender's calculation method can change the number by thousands
- At renewal there is no penalty at all — sometimes waiting wins
- I'll get your real payout figure before you decide

The short answer
You are never locked in. A closed mortgage is not a prison; it is a contract with an exit fee. You can move to another lender on any day of your term, and your current lender cannot refuse.
What stops most people is not permission — it is arithmetic. Breaking a mortgage mid-term triggers a prepayment penalty, and on a fixed mortgage with real time left in the term that penalty is frequently large enough to erase several years of savings from a better rate.
So the question is never "can I?" It is: does the saving over the remaining term exceed the cost of getting out? That is a calculation, and it has a definite answer for your specific mortgage. It just is not the answer a rate comparison site can give you, because the number that decides it is buried in your contract.
One important distinction before the numbers. Leaving at renewal is completely different: your term has ended, the contract is complete, and there is no penalty at all. If your maturity date is within a year, that alone often settles the question. See switching lenders at renewal.
What breaking actually costs
The penalty is usually the higher of two calculations:
- Three months' interest on your remaining balance.
- The interest rate differential (IRD) — roughly, the interest your lender expects to lose over the rest of your term because rates have moved.
Those two numbers are not close to each other. The Financial Consumer Agency of Canada publishes a worked example that shows the gap plainly: a $200,000 balance at 6% with 36 months left in a five-year term, where the current three-year posted rate is 4%.
Interest rate differential → about $12,000
The lender charges the higher one → $12,000, plus a possible administration fee
Four times the difference, on a balance far smaller than most GTA mortgages. Scale that to a $700,000 Toronto balance and you can see why "I'll just switch to that better rate I saw" often does not survive contact with the payout statement.
Here is the part that is genuinely useful, and that you will not hear in a branch: how your lender calculates the IRD changes the answer by thousands of dollars. Many big banks compute it against their posted rates — rates nobody actually pays — which inflates the differential. Many monoline lenders compute it against the contract rate. Two mortgages with the same balance, the same rate and the same time remaining can produce wildly different penalties purely because of a clause in the paperwork.
That clause is also why I will not estimate your penalty from a rule of thumb. I get the actual payout figure from your lender in writing, and we decide from that. The full mechanics are in the prepayment penalty guide.
When breaking early does make sense
It is not always the wrong move. These are the situations where the maths tends to work.
You are near the end of your term
The IRD shrinks as the remaining term shortens, because there is less lost interest to compensate. With six or nine months to go the penalty is often small enough that moving early to secure a rate is worth it — particularly if you can hold a rate now.
Your rate is well above current market
The IRD exists because your lender loses out when rates have fallen. If your rate is at or below current market, the IRD may be minimal or zero, leaving only three months' interest. That is a very different decision.
You have a variable-rate mortgage
Variable mortgages commonly carry a simpler penalty structure than fixed ones. It depends on your contract rather than on a rule, so it still has to be checked — but the exit is frequently far cheaper.
You need the money, not just a better rate
If you are consolidating expensive debt or funding something time-sensitive, the comparison is not penalty versus rate saving. It is penalty versus what the alternative borrowing costs. Credit card interest can dwarf a penalty quickly. See debt consolidation.
You are selling anyway
Many mortgages are portable, so moving the mortgage with you avoids the penalty entirely. Worth establishing before you list, because it affects which lender you want to be with next.
The new lender covers the penalty
Occasionally a lender will absorb part of the cost to win the business. Rare on large penalties, and it usually shows up as a higher rate, so it needs pricing rather than taking at face value.
How to decide, properly
Twenty minutes of work replaces a lot of guessing.
- Get your actual payout figureCall your lender and ask for a written payout statement, or ask me to. Not an estimate from a calculator — the real number, including any discharge and administration fees.
- Work out the saving over the remaining termNot the monthly difference, and not the saving over 25 years. Only the months left in your current term, because at renewal you could move for free anyway.
- Subtract the costsPenalty, plus legal, appraisal and discharge fees, less whatever a new lender covers. If your mortgage is a collateral charge, add a discharge and new registration — see collateral charges.
- Compare against simply waitingPrice what you could get at renewal. If the gap is small, waiting is almost always better, because waiting costs nothing and carries no risk.
- Decide on the number, not the feelingBeing annoyed with your bank is a real feeling and a poor reason to pay a five-figure penalty. If the maths says wait, the right move is to diarise your renewal date and start the conversation 120 days out.
