When can a late fee be an illegal penalty in a contract in Ontario?
In Ontario, a “late fee” can be unenforceable if it is really an interest charge on overdue money that effectively exceeds the Criminal Code limit, which the courts can treat as a criminal offence (e.g., Criminal Code, R.S.C. 1985, c. C-46). Courts also look at whether the penalty is a disguised interest rate rather than a genuine, related recovery of disbursement costs from collecting the debt, as in Garland v. Consumers’ Gas Co., [1998] 3 S.C.R. 112 and De Wolf v. Bell ExpressVu Inc., 2009 ONCA 644. If the late charge, even when first imposed, calculates into an excessive annual rate, it may stay unlawful and not become lawful later just because the balance persists, so a severability clause may not save an unlawfully structured fee.

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. A contract prescribing an interest rate that exceeds the sixty (60%) percent is an illegal contract; Garland v. Consumers' Gas Co., [1998] 3 S.C.R. 112; albeit, if the contract contains a severability clause, then such a clause may preserve the complete 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.
