IOU (Canada)

A Canadian IOU (Canada) — short for "I Owe You" — is a simple written acknowledgment that one person owes a debt to another in Canada. An IOU is the most basic form of debt documentation — less formal than a promissory note governed by the Bills of Exchange Act (R.S.C. 1985, c. B-4) but still legally enforceable as a contract when it contains the essential elements: identification of the parties, the amount owed, and a repayment commitment.

While an IOU lacks the detailed terms of a formal loan agreement or promissory note, Canadian courts have consistently treated written IOUs as admissible evidence of a debt obligation. Section 13 of Ontario's Limitations Act 2002 (S.O. 2002, c. 24) and Section 24 of British Columbia's Limitation Act (S.B.C. 2012, c. 13) both recognize that a written acknowledgment of a debt can restart the limitation period, which is critical in debt collection. Section 2925 of the Civil Code of Quebec (RLRQ, ch. CCQ-1991) establishes a three-year limitation period for contractual claims in Quebec, compared to the two-year standard in most common-law provinces under provincial Limitations Acts.

Section 3 of the Interest Act (R.S.C. 1985, c. I-15) governs interest on debts in Canada and requires that any interest rate be expressed as a yearly rate. If an IOU specifies an interest rate, Section 4 of the Interest Act requires that rate to be expressed as an annual rate. If no rate is stated, the default rate of 5% per annum applies on any court judgment under Section 3 of the Interest Act. Lenders should be cautious not to charge rates that could be deemed criminal under Section 347 of the Criminal Code (R.S.C. 1985, c. C-46), which since January 1, 2025 prohibits effective annual interest rates exceeding 35%.

For personal loans between family members or friends in Canada, an IOU provides sufficient documentation to avoid misunderstandings, protect relationships, and create a paper trail for tax purposes if the Canada Revenue Agency (CRA) questions whether the transfer was a gift or a loan. Sections 74.1 to 74.5 of the Income Tax Act (R.S.C. 1985, c. 1 (5th Supp.)) contain attribution rules that can apply when funds are loaned between spouses or to minor children. Section 20(1)(c) of the Income Tax Act allows a lender to deduct interest income paid on borrowed money used to earn income. Part 1 of the Personal Information Protection and Electronic Documents Act (PIPEDA, S.C. 2000, c. 5), enforced by the Office of the Privacy Commissioner of Canada (OPC), governs any personal data collected under this document. The Competition Act (R.S.C. 1985, c. C-34), enforced by the Competition Bureau, protects consumer rights. The Financial Consumer Agency of Canada (FCAC) and provincial superior courts have jurisdiction over consumer credit disputes. Employment and Social Development Canada (ESDC) administers related federal programs. The Federal Court of Canada has jurisdiction over federal matters under Section 18 of the Federal Courts Act (R.S.C. 1985, c. F-7). Parties executing an IOU in Canada should confirm the document reflects current law, including any amendments enacted since the original drafting date.

When lending money to a friend or family member and wanting a simple written record without the formality of a full loan agreement governed by the Bills of Exchange Act (R.S.C. 1985, c. B-4).

When borrowing a relatively small amount and the parties agree on straightforward repayment terms that do not require complex interest calculations or instalment schedules under Section 3 of the Interest Act (R.S.C. 1985, c. I-15).

When documenting a debt that has already occurred but was initially undocumented, to formalize the obligation in writing and establish the date from which limitation periods under provincial Limitations Acts begin to run.

When a creditor needs a written acknowledgment of debt to restart the limitation period under provincial limitations legislation — specifically Section 13 of Ontario's Limitations Act 2002 (S.O. 2002, c. 24), Section 24 of British Columbia's Limitation Act (S.B.C. 2012, c. 13), or Section 2925 of the Civil Code of Quebec (RLRQ, ch. CCQ-1991) for Quebec creditors.

When separating a loan from a gift for tax and estate planning purposes, so the Canada Revenue Agency (CRA) or estate trustees can identify debts owed to a deceased person's estate. The attribution rules in Sections 74.1 to 74.5 of the Income Tax Act (R.S.C. 1985, c. 1 (5th Supp.)) apply when funds are loaned between spouses or to minor children, making documentation critical. Section 160 of the Income Tax Act imposes personal liability on recipients of property transferred without fair market value consideration, so a properly documented IOU establishes the commercial nature of the transfer. The Canada Revenue Agency (CRA) may request evidence of the loan arrangement during an audit of either party's T1 income tax return. Provincial superior courts — including Ontario's Superior Court of Justice, British Columbia's Supreme Court, and Alberta's Court of King's Bench — resolve disputes arising from unpaid IOUs. The Financial Consumer Agency of Canada (FCAC) publishes consumer guidance on personal lending obligations. Part 1 of the Personal Information Protection and Electronic Documents Act (PIPEDA, S.C. 2000, c. 5), enforced by the Office of the Privacy Commissioner of Canada (OPC), governs personal data processed under this agreement. The Competition Act (R.S.C. 1985, c. C-34), enforced by the Competition Bureau, protects consumer rights. Forms-legal.com provides this template as a starting point for Canada-compliant documentation.

Parties — Full legal names of the borrower and the lender, making clear who owes money to whom. For corporate borrowers, include the legal name exactly as registered with Corporations Canada or the relevant provincial registry under Section 10 of the Canada Business Corporations Act (R.S.C. 1985, c. C-44) or the equivalent provincial Business Corporations Act.

Amount — The exact amount borrowed in Canadian dollars (CAD), stated numerically and in words to avoid disputes. Section 9 of the Bills of Exchange Act (R.S.C. 1985, c. B-4) requires that the sum be certain in a negotiable instrument; an IOU should follow this standard for clarity.

Date of Loan — The date the money was lent or will be lent, establishing when the obligation arose and when the limitation period begins. Section 5 of Ontario's Limitations Act 2002 (S.O. 2002, c. 24) and Section 6 of British Columbia's Limitation Act (S.B.C. 2012, c. 13) both start the clock from the date of discovery of the claim.

Repayment Date — When the debt must be repaid in full. A specific calendar date is preferable to an open-ended "on demand" arrangement because courts can more easily calculate the limitation period from a fixed repayment date. Section 2925 of the Civil Code of Quebec (RLRQ, ch. CCQ-1991) governs prescription periods for contractual obligations in Quebec.

Interest — Whether interest applies, and if so, the annual interest rate as required by Section 4 of the Interest Act (R.S.C. 1985, c. I-15). All interest rates must be expressed as yearly rates. Section 347 of the Criminal Code (R.S.C. 1985, c. C-46) sets the criminal interest rate ceiling at 35% annual percentage rate as of January 1, 2025. Any provision for interest exceeding that limit is void. For loans between related parties, the Canada Revenue Agency (CRA) prescribed rate under Section 20(1)(c) of the Income Tax Act (R.S.C. 1985, c. 1 (5th Supp.)) is relevant to avoid deemed interest income attribution under Sections 74.1 to 74.5 of the Income Tax Act.

Signature — The borrower's signature is essential. The lender's signature is optional but recommended for completeness. Electronic signatures are valid in all Canadian provinces under provincial Electronic Transactions Acts — including Ontario's Electronic Commerce Act (S.O. 2000, c. 17), British Columbia's Electronic Transactions Act (S.B.C. 2001, c. 10), and Alberta's Electronic Transactions Act (S.A. 2001, c. E-5.5) — provided the signatory can be reliably identified.

Witness — A witness signature adds credibility and helps prove authenticity if the IOU is ever disputed before Ontario's Superior Court of Justice, British Columbia's Supreme Court, or another provincial superior court. The witness should be a disinterested adult who is not a party to the transaction.

Governing Law — Specify the province whose law governs and the courts with jurisdiction. Part 1 of the Personal Information Protection and Electronic Documents Act (PIPEDA, S.C. 2000, c. 5), enforced by the Office of the Privacy Commissioner of Canada (OPC), governs any personal data collected. The Competition Act (R.S.C. 1985, c. C-34), enforced by the Competition Bureau, protects consumer rights. The Financial Consumer Agency of Canada (FCAC) provides guidance on consumer lending.

Default and Remedies — State what happens if the borrower fails to repay by the due date. For amounts within the small claims monetary limit — $35,000 in Ontario under Rule 1.02 of the Rules of the Small Claims Court (O. Reg. 258/98), $35,000 in British Columbia under Section 3 of the Small Claims Act (R.S.B.C. 1996, c. 430), and $50,000 in Alberta under Part 2 of the Alberta Rules of Court — the lender may sue in small claims court without legal representation. For larger amounts, the action proceeds in the Ontario Superior Court of Justice, British Columbia Supreme Court, or the Court of King's Bench of Alberta. A default clause may also provide for acceleration (the full outstanding balance becomes immediately due), payment of the lender's reasonable legal costs, and post-judgment interest at the provincial rate under the Courts of Justice Act (R.S.O. 1990, c. C.43) or equivalent provincial statute. Forms-legal.com provides this template as a starting point for Canada-compliant documentation.
