A family loan agreement is valid in Canada if it names the parties, states the amount and repayment terms, and is signed — no lawyer or notary required, and e-signatures count. The four mistakes that sink them: leaving the loan verbal, stating interest without a per-annum rate, ignoring the limitation clock, and never enforcing the terms.
Lending money to family or a friend is one of the most common financial moves Canadians make — and one of the least protected. More than half of Canadians have lent money to someone close to them, and a large share of those loans are never fully repaid. The damage is rarely just financial: about one in four lenders say it hurt the relationship.
A written loan agreement prevents most of that before it starts. This guide explains what a family loan agreement is, what it needs to be valid in Canada, the quiet mistakes that make agreements unenforceable, and how to create one without hiring a lawyer.
What a family loan agreement actually is
It's an ordinary contract between a lender and a borrower who happen to know each other. It records the amount, the repayment plan, whether interest applies, and what happens if payments stop. It doesn't need special legal language — it needs clear terms, two parties with legal capacity, and signatures. What it changes isn't the law but the conversation: "I thought it was a gift," "we never set a date," and "that's not what we agreed" all disappear once it's written down.
What it must include
- The legal names of both people
- The amount and the date the money changes hands
- The repayment schedule — lump sum, instalments, or a flexible deadline
- The interest rate, if any, written as a clear annual rate (see below)
- What counts as default, and what happens then
- The governing province
The four mistakes that sink Canadian agreements
1. Stating interest the wrong way
Under the federal Interest Act, if you express interest for a period shorter than a year — "2% per month," say — without also stating the equivalent annual rate, your recovery can be capped at just 5% per year, no matter what you intended. One drafting slip quietly rewrites the deal.
2. Going over the criminal rate
Since January 1, 2025, Canada's criminal interest rate is 35% APR (down from 60% effective annual, with the calculation method itself changed). A clause above that isn't just unenforceable — it's a Criminal Code problem.
3. Signing with someone underage
The age of majority is 18 in Alberta, Manitoba, Ontario, PEI, Quebec, and Saskatchewan, and 19 in BC, New Brunswick, Newfoundland & Labrador, Nova Scotia, and the territories. Contracts with minors are generally voidable by the minor.
4. Using a promissory note when you meant a loan agreement
Many free "IOU" templates are actually promissory notes, which fall under the federal Bills of Exchange Act — a regime built around original ink documents. If you want to sign electronically, you want a loan agreement, not a note.
Are e-signatures valid for this?
Yes. Electronic signatures are recognized federally and in every province for ordinary contracts, under laws modelled on the Uniform Electronic Commerce Act (Quebec has its own framework). What gives an e-signature weight if it's ever challenged is the evidence around it: timestamps and proof the document wasn't altered after signing. That's why the signing certificate matters more than the signature image itself.
What if they don't pay?
A signed agreement is exactly the evidence small claims court is designed around — and small claims covers almost every family loan in Canada: up to $50,000 in Ontario (since October 2025), $100,000 in Alberta, $50,000 in Saskatchewan, and $15,000–$35,000 elsewhere. Most provinces let you file without a lawyer. Watch the limitation clock, though: in Ontario, most claims must be started within two years of discovering the default.
Gift or loan? Decide on purpose
Canada has no general gift tax, but the distinction still matters: mortgage lenders treat gifted and borrowed down payments differently, and in a relationship breakdown, money documented as a loan to your child can be treated very differently from an undocumented transfer. Decide which one you mean — and put it in writing.
Common questions
Does a family loan agreement need a lawyer?
No. It's a self-help contract. Complex situations — security on property, large business loans — deserve legal advice, but a standard personal loan does not.
Does it need a witness or notary?
Generally no for ordinary loan agreements, though notarization can add evidentiary comfort for large amounts.
Can I just write it myself?
You can — but the four mistakes above are exactly the ones self-drafted and free-template agreements make, because they're invisible unless you know Canadian statute.
Validity is one thing; proving the copy you hold is the one that was signed is another. LendRight seals every agreement with a verifiable SHA-256 fingerprint — document integrity and the SHA-256 seal.
