When does a late fee become an illegal penalty in Ontario?
VP Legal Services & Notary can help you review your contract to see whether a late fee is actually a disguised interest charge that may exceed Ontario’s limits. Under the Criminal Code, R.S.C. 1985, c. C-46, s. 347 (60% per year threshold), a “late fee” that functions like interest can be unenforceable, and courts may look at the substance rather than the label. If the fee is tied to real collection disbursement costs instead of added cost of extending credit, it may be treated differently, so the contract wording and numbers matter.

When Is a Late Fee An Illegal Penalty
Business owners often attempt to encourage prompt payment by imposing delayed payment penalties (late fees) upon those who fail to pay on time. Unfortunately, contracts may be deemed unlawful and therefore unenforceable when the contract is written in such a way as to impose, or appear to impose, an improper late fee. Commonly, the late fee calculates to an amount that violates the Criminal Code, R.S.C. 1985, c. C-46, section 347, whereas charging an interest rate beyond sixty (60%) percent per annum is deemed a criminal offence. Any contract that prescribes an interest rate in excess of the maximum allowable sixty (60%) percent is therefore an illegal contract; Garland v. Consumers' Gas Co., [1998] 3 S.C.R. 112. Do note that a severability clause may save the entire contract from becoming void.

While a business may attempt to disguise interest as a late fee, courts will view a late fee for what a late fee is - an interest charged as an additional amount of money due, and arising from, the extension of credit for an outstanding balance of monies owed. An exception applies if it is shown that the late fee genuinely correlates to the recovery of a disbursement cost incurred in the collection of the debt rather than as an additional fee correlated to the further advancement of the debt; De Wolf v. Bell ExpressVu Inc., 2009 ONCA 644; Garland, supra.
As an example, consider the business that charges a ten 00/00 ($10.00) dollar late fee when a monthly payment of one hundred 00/00 ($100.00) is overdue by seven (7) days. This late fee actually calculates as a ten (10%) percent additional charge upon the actual amount due. This ten (10%) percent late fee imposed upon a one week overdue account produces an exorbitant, and unlawful, five hundred twenty (520%) percent annual interest rate. Note that the fact that this interest appears lower, and actually does calculate lower, over a greater period of time, it is the trigger date that causes the unlawfulness. While the $10.00 late fee charged on the 7th day is unlawful, it might appear that if six months later the same $10.00 is still outstanding that the amount, by then, is a lawful twenty (20%) percent interest; however, the very fact that the amount was unlawful when originally imposed continues to make the amount unlawful. What was at first unlawful fails to become lawful.
Conclusion
When an agreement contains a clause for late fees or other form of delayed payment penalty, such is viewed as an attempt to charge interest on monies due. Where the late fees, as a disguised interest, calculate to an interest rate beyond the legally allowable interest rate, the late fees are viewed as unlawful. Furthermore, even if the interest rate may be legal, late fees or a payment penalty that goes beyond the costs of recovering the genuine amount due are, generally, deemed unenforceable.
NOTE: A considerable volume of inquiries featuring “lawyers near me” or “best lawyer in” typically indicates a requirement for prompt and proficient legal assistance rather than a specific type of legal professional. In Ontario, licensed paralegals are governed by the same Law Society that regulates lawyers and are permitted to represent clients in specific litigation matters. Advocacy, legal analysis, and procedural expertise are fundamental to this position.
