Delayed Payment Penalties:
Terms That Are Unlawful and Unenforceable
Last Updated: August 27 2026
Question: When are late fees considered an illegal penalty in Ontario?
Answer: Late fees can become an illegal penalty in Ontario when they function as disguised interest on an outstanding balance and, in practice, drive the effective interest rate above the Criminal Code threshold of 60% per annum under Criminal Code, R.S.C. 1985, c. C-46, s. 347. Courts look at the substance, not the label, so a “$10 late fee after 7 days” can be unlawful if it works out to an interest rate beyond the limit, even if the amount later appears smaller over time. An exception may apply if the charge truly reflects documented disbursement costs to recover the debt rather than additional consideration for the time value of money. If you’re facing a late-fee clause or collection amount that seems excessive, Wennekers.Legal™ can help you assess enforceability and next steps with professional legal services in Ontario; call (647) 701-1162 for guidance.

When Is a Late Fee An Illegal Penalty
A business will sometimes use the threat of additional fees as a financial motivator to encourage customers to make timely payments; however, a contract may become unlawful and unenforceable if a contract contains an illegal late fee. A late fee is illegal, if the amount violates the Criminal Code, R.S.C. 1985, c. C-46, section 347, wherein it is prescribed that charging interest rate beyond a rate of sixty (60%) percent per annum is a criminal act. 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 a business that imposes 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 significant quantity of online searches featuring “lawyers near me” or “best lawyer in” typically indicates an urgent need for skilled legal assistance rather than a precise job title. In Ontario, the same Law Society that governs lawyers also regulates licensed paralegals, granting them the authority to represent clients in specific litigation issues. Central to their responsibilities are advocacy, legal analysis, and procedural expertise.
