Promissory Notes in Canada: Legal Requirements for Enforceability

16 Jun 2026 4 min read No comments Money, Taxes & IP Canada

A promissory note is a legally binding document where you promise to repay a specific loan. To be legally enforceable in Canada under the federal Bills of Exchange Act, it must contain an unconditional promise to pay a set amount of money, and it must be signed by the borrower.

Lending money to family, friends, or business partners can put a strain on your relationships. Many Canadians make the mistake of relying on verbal agreements or a simple handshake when lending large sums of cash. Unfortunately, if the relationship sours, getting your money back without a written record can be incredibly difficult.

A promissory note acts as clear, written proof of the debt. 📝 It provides protection for the lender and clear expectations for the borrower. However, a hastily scribbled note on a napkin might not hold up in a Canadian court. To ensure your document is legally valid, it is always a smart choice to consult a local law firm from our directory to draft the agreement properly.

Step-by-Step: Drafting and Enforcing a Promissory Note in Canada

Whether you are lending money to a startup in Toronto, a family member in Calgary, or a partner in Vancouver, the legal requirements for a promissory note are consistent across the country. Here are the steps to create and enforce one.

Step 1: Drafting the Essential Terms

For a note to be valid under the Bills of Exchange Act, it must clearly state the principal loan amount, the interest rate (if any), and the exact date or conditions for repayment. The promise to pay must be “unconditional.” You cannot include clauses that say, “I will pay you back only if my business succeeds.”

Step 2: Signing and Witnessing

The borrower must sign the document for it to be enforceable. 🖊 While Canadian law does not strictly require a promissory note to be notarized or witnessed, having an independent third party witness the signature adds significant legal weight if the borrower later claims they never signed it.

Step 3: Storing the Original Document

As the lender, you must keep the original signed note in a safe place. If you ever need to take legal action, the court will typically want to see the original physical document, often referred to as a “wet signature” copy, rather than a photocopy.

Step 4: Enforcement Through the Courts

If the borrower defaults and refuses to pay, you must take legal action. 🔨 For smaller debts (usually under $35,000 CAD, depending on the province), you can file a claim in Small Claims Court. For larger amounts, your lawyer will need to file a lawsuit in a higher court, such as the Superior Court of Justice in Ontario or the Court of King’s Bench in Alberta.

How Much Does It Cost to Draft and Enforce?

Securing your loan properly involves some upfront costs, but it saves money in the long run. Keep these 2026 Canadian dollar (CAD) estimates in mind:

  • Lawyer Drafting Fees: Hiring a law firm to draft a standard promissory note usually costs between $500 and $1,500 CAD.
  • Small Claims Filing Fees: If you need to sue, filing a claim yourself costs roughly $100 to $350 CAD depending on your province.
  • Civil Litigation: Hiring a lawyer to enforce a large debt in the Superior Court can easily exceed $10,000 CAD in legal fees.

How Long Does the Process Take?

Drafting a promissory note is very quick. A skilled lawyer can usually prepare the document within a few days. However, if you are forced to sue to collect your money, the legal system is slow. A small claims lawsuit can take 6 to 12 months, while a higher court case might drag on for over two years.

Frequently Asked Questions (FAQ)

Can I charge any interest rate I want?

No. While you can charge interest, the Criminal Code of Canada makes it illegal to charge a criminal interest rate, which is generally anything exceeding 60% effective annual interest. Most private loans charge between 5% and 15%.

Does a promissory note expire in Canada?

Yes. The limitation period to sue for a debt is typically 2 years from the date of default in provinces like Ontario, Alberta, and British Columbia. If you wait too long to enforce the note, you lose your legal right to collect.

What happens if the borrower dies?

If the borrower passes away, the debt does not disappear. You must present the promissory note as a claim against the deceased person’s estate. You will be paid out of their assets before inheritances are distributed.

Do I need a lawyer to make it legal?

You are not legally required to use a lawyer. However, if the wording is ambiguous or fails to meet the strict requirements of the Bills of Exchange Act, a judge might declare it unenforceable. Using a law firm is highly recommended for large sums.
