The Economic Logic Behind the Mortgage Penalty
When you sign a fixed-rate mortgage contract, your lender commits to providing funds at a set rate for the entire term. In return, it counts on the interest income generated by your loan. If you repay early, the lender must reinvest those funds in a market where rates may be lower, incurring a real financial loss.
The mortgage break penalty is therefore compensation for an anticipated loss. It aims to make the lender financially neutral in the face of your decision to break the contract. This approach is recognized by the Civil Code of Quebec and governed federally by OSFI Guideline B-20.
The Two Calculation Methods in Brief
Canadian lenders use two main methods to calculate the penalty. The first is the three months' interest penalty: the mortgage balance is multiplied by the contractual rate, then divided by four (three months out of twelve). The second is the interest rate differential (IRD), which calculates the gap between your contractual rate and the lender's current rate for the remaining duration, applied to the balance for each month remaining in the term.
Why Penalties Vary From One Lender to Another
The major difference between lenders lies in the comparison rate used for the IRD calculation. Canada's Big 5 banks (RBC, TD, BMO, Scotiabank, CIBC) often use their posted rate as the reference, which is typically higher than the rate actually given to the client. This choice artificially inflates the rate gap and therefore the penalty. Monoline lenders and several Desjardins caisses use the discounted rate instead, producing significantly lower penalties.
The Role of the Mortgage Broker
A mortgage broker certified by the Autorite des marches financiers (AMF) has the obligation to disclose and explain penalty clauses to clients. Under the LDPSF, the broker must act in the client's best interest and provide complete information on the potential costs of breaking a mortgage, including the penalty, notary fees, discharge fees and any other exit costs.
- The penalty compensates the lender's lost interest income.
- The IRD is generally higher than three months' interest when rates have dropped.
- The Big 5 banks use the posted rate, which increases the penalty.
- Monoline lenders often offer fairer and more transparent penalties.
- The AMF-certified broker must inform the client of potential penalties before signing.
