If you sell your Quebec home before your closed mortgage term ends, your lender will usually charge a prepayment penalty: the higher of three months’ interest or the interest rate differential (IRD) on a fixed-rate loan, and usually three months’ interest on a closed variable-rate loan, according to Quebec’s Autorité des marchés financiers (AMF). On a fixed rate, the IRD can be several times larger than three months’ interest. Porting the mortgage to your next home, timing the sale near your renewal date, or using your annual prepayment privileges can reduce or avoid it.
This guide explains how the penalty is calculated, how large it can be, and the options to discuss with your lender before you list. It is general information; your mortgage contract and your lender’s written figure are what count.
Usually, if your mortgage is closed and you repay it before the end of the term. The Financial Consumer Agency of Canada (FCAC) lists paying back your entire mortgage before the end of the term, “including when you sell your home,” as one of the situations where a lender may charge a prepayment penalty (FCAC). An open mortgage can be repaid at any time without a penalty, and no penalty applies if the sale closes on or after your term’s maturity date.

According to the FCAC, the penalty is usually the higher of:
The FCAC says the lender will usually use the IRD when your mortgage rate is higher than the current interest rate and you signed your current contract less than five years ago. The method varies by lender: the first rate can be the posted rate when you signed or your discounted contract rate, and the second can be the current posted rate for a similar term, or that rate minus the discount you were originally given (FCAC). The AMF notes that some lenders use posted rates on both sides, which is why the rates used matter so much (AMF).
Quebec’s financial regulator illustrates the IRD on a fixed-rate mortgage as: mortgage balance × (posted annual rate at signing − current posted annual rate) × years remaining. In its example, $200,000 × (4.5% − 4.09%) × 4 years = $3,280, compared with three months’ interest of about $1,500 at 3% (AMF). The “posted rate at signing” is the rate you pay plus the discount you received.
| Assumption | Value |
|---|---|
| Outstanding balance | $200,000 |
| Your rate | 6% |
| Months left | 36 of a 5-year term |
| Lender’s current posted rate for 36 months | 4% |
| Three months’ interest | $3,000 |
| IRD | $12,000 |
| Penalty charged (the higher) | $12,000, plus any administration fee |
That gap, $3,000 versus $12,000, is why sellers should ask for the figure before choosing a listing date, not after accepting an offer.
Usually it is smaller. “If you have a closed mortgage with a variable interest rate, the applicable penalty usually amounts to three months’ interest,” the AMF says (AMF). Three months’ interest is roughly your balance × your annual rate ÷ 4: on $400,000 at 4.5%, that is about $4,500. Check your contract: the FCAC requires federally regulated lenders to disclose prepayment privileges and penalties in an information box at the beginning of the mortgage agreement (FCAC). Caisses and other provincially regulated lenders set out their terms in your contract as well; the AMF advises reading that section carefully and asking the lender to explain it (AMF).
The penalty is not the only cost. The FCAC lists fees to ask about before you break a closed mortgage (FCAC, Breaking your mortgage contract):
If you are staying with the same lender for your next home, ask too about a blend-and-extend, which the FCAC describes as extending your term early and blending the old and new rates without a prepayment penalty, though administrative fees may apply (FCAC).
The notary pays your mortgage balance, the penalty and the lender’s discharge fees from the sale price, then adjusts municipal and school taxes to the date of the deed. Brokerage commission plus GST and QST is also deducted. See closing costs in Quebec and who pays the notary in a Quebec home sale.
Generally only when the mortgage is open or the term has matured. Within a closed term, a penalty usually applies unless you port the mortgage or stay within your prepayment privileges.
Usually, but not always. The AMF says it “usually amounts to three months’ interest”; your contract sets the actual method (AMF).
Possibly: administration, appraisal, reinvestment and discharge fees, and repayment of any cash back (FCAC).
The method is set by your contract. If you are buying again with the same lender, ask about porting or a blend-and-extend, which the FCAC lists as ways to avoid a prepayment penalty.
The seller. It is part of paying off the seller’s loan and is deducted from the sale proceeds at the notary.
