How to lend money to a family member legally in Canada

Lending money to a relative is completely legal in Canada — you don't need a licence, a notary, or a lawyer. But "legal" isn't the same as "safe." Doing it legally means clearing a handful of specific hurdles the law actually cares about: making a real agreement instead of a vague understanding, keeping any interest under the Criminal Code's ceiling, signing in a way the law recognizes, and acting inside the window where a court will still help you. Miss those and the loan stays legal — it just stops being enforceable. This is the complete legal walkthrough, with the statutes and cases that decide it.

One thing to get straight up front, because it's the source of most confusion: the rules that matter most are federal and identical coast to coast — the interest limit, the tax treatment, and the basic law of contracts. Only a few pieces change at the provincial border, and even those mostly differ in the number, not the principle. Here's the split.

What "legally" actually means here

People assume the legal risk in a family loan is some licensing rule or a tax trap. It almost never is. The real obstacle is quieter: Canadian law starts from two presumptions that both work against an undocumented family loan, and your job is to rebut them.

The first comes from contract law. When money moves between family members in a casual setting, a court may presume the arrangement was not intended to create legal relations — that it was a domestic understanding, not a contract. That presumption is rebuttable, but the person claiming a binding loan has to do the rebutting.

The second comes from the law of trusts. The Supreme Court of Canada held in Pecore v. Pecore, 2007 SCC 17, that a gratuitous transfer between adults — including a parent to an adult child — is presumed not to be a gift. That cuts in the lender's favour, but it still leaves the question of terms wide open: even if the money wasn't a gift, what was actually owed, and when?

Here's the useful part: a single act rebuts both presumptions at once. A written agreement, signed at the time, says this was meant to be legally binding and these were the terms. Everything below is really about doing that one thing properly — and the few other rules that sit around it. In Quebec, the framing differs — its civil law doesn't use these common-law presumptions — but the destination is identical: a clear written agreement is what proves the loan and its terms. (If you're still unsure whether your transfer is even a loan, start with gift or loan: how to decide.)

The six legal checkpoints, at a glance

A family loan is "legal" once it clears these. Each links to the deeper guide on that step.

1. Decide it's a loan, not a giftSettle the intention before the money moves, so neither presumption above can be used against you. Gift or loan?
2. Agree clear, certain termsAmount, date advanced, how and when it's repaid. Vague terms are a legal weakness, not a kindness.
3. Put it in writing and both signThis rebuts the "not legally binding" presumption and creates proof. E-signatures are valid. How to write one
4. Keep interest lawfulNever above the 35% criminal rate; at least the CRA prescribed rate if you're splitting income. Charging interest
5. Handle special casesMinors, spouses, secured loans, and money sent from overseas each carry extra legal rules.
6. Stay inside the enforcement windowIn most provinces you have roughly two years to sue once a payment is missed. If they don't repay

The legal anatomy of an enforceable loan

For a family loan to be a contract a court will enforce, the same ingredients are needed as for any other agreement. You don't have to recite them — you just have to not skip them:

• An offer and acceptance. One person offers to lend on certain terms; the other accepts. A signed document captures both in one place.
• Consideration. Each side gives something. In a loan, the lender advances money and the borrower promises to repay — that exchange is the consideration.
• Intention to create legal relations. The point above: with family, you have to signal this deliberately, and writing it down is how you do it.
• Certainty of terms. A court can't enforce "pay me back when you can" if "when you can" is undefined. The more precise the amount, dates, and triggers, the more enforceable the loan.
• Capacity. Both people must be legally able to contract — which is where lending to a minor gets complicated (below).

Notice what's not on this list: a notary, a witness, a lawyer, or special wording. None of those are legally required for an ordinary family loan. What the law rewards is clarity and proof, not formality. (Those elements are the common-law ones; Quebec's Civil Code sets out its own but comparable requirements for forming a contract — the practical checklist comes out the same.) For the practical line-by-line of what to include, see how to write a family loan agreement and what a personal loan agreement needs to include.

Putting it in writing — and why e-signatures are legally valid

A verbal family loan can be a real, binding contract. The problem is purely evidentiary: if it's ever disputed, the terms collapse into one person's memory against another's, and you also have to fight off the "it wasn't meant to be binding" presumption. A short written agreement solves both at once. (More on the verbal-vs-written question in is a verbal loan agreement legally binding?)

You don't need paper, either. Electronic signatures carry the same legal weight as ink for ordinary contracts across Canada.

One legal nuance worth knowing — and it's uniform across those statutes, because they share a common model — is that they generally carve out negotiable instruments, and a traditional promissory note is one. That doesn't make an e-signed note worthless, but it's a reason a signed loan agreement is usually the cleaner, lower-risk document for family lending. We unpack the trade-off in promissory note vs loan agreement.

The legal limits on interest

You're free to lend interest-free, and most families do. You're also free to charge interest — but there's a hard legal ceiling, and as of last year it's lower than it used to be.

For nearly every family loan this is academic — you're charging zero, or a few percent. But it's a genuine criminal limit, not a guideline, so it's worth knowing the ceiling exists. The detail (and how to set a fair, lawful rate) is in charging interest on a family loan and, for siblings specifically, how much interest can I charge my brother?

There's a second, opposite rule that trips people up. If your aim is to split investment income with a lower-earning relative, an interest-free or too-cheap loan backfires: the CRA's attribution rules tax the income back in your hands. To make income-splitting work, the loan generally has to charge at least the CRA prescribed rate — 3% as of mid-2026 — with that interest actually paid within 30 days of year-end. So the lawful band for an income-splitting family loan runs from the prescribed rate at the bottom to the criminal rate at the top. See the CRA prescribed rate for family loans and, for couples, spousal loans in Canada.

Situations the law treats differently

Most family loans are simple. A few aren't, because the law layers extra rules on top.

Lending to a minor

Capacity is the issue. A contract with someone under the age of majority — which is 18 in some provinces and 19 in others — is generally not enforceable against the minor except for "necessaries," so a straightforward loan to a 16-year-old isn't something you could realistically sue on. In practice, money for a minor is usually structured as a gift, held in trust, or lent to a parent — not as a loan to the child. The limitation clock also pauses for minors until they reach majority, which matters if you ever lend to a young adult and a dispute arises.

Lending to a spouse or partner

Two legal systems collide here. First, family law: money moving between spouses can affect property division if the relationship ends, and whether it was a loan or a gift changes the result — so documentation matters even more, not less. Second, tax: the CRA attribution rules described above apply with full force between spouses, which is exactly why the prescribed-rate spousal loan structure exists.

Secured loans and guarantees

You can take security — a charge against a car or, for larger sums, a property — so that you're not just an unsecured creditor if things go wrong. Security has to be set up properly to be effective (registration rules vary), and that's the one situation where a lawyer genuinely earns their fee. A personal guarantee from a third party (say, a co-signing parent) is also enforceable, and notably the new interest rules leave some gaps around guarantors, so get advice before relying on one.

Money sent from overseas

Cross-border family money adds two wrinkles: proof of the loan for a Canadian lender or mortgage, and source-of-funds questions from banks. If a relative abroad is helping with a home purchase, whether it's papered as a gift or a loan has real consequences. We cover it in family sending money from overseas to buy a house and family down payments and CRA rules.

How long your loan stays legally enforceable

This is the checkpoint people forget, and the one that quietly kills otherwise-valid loans. A legal right to be repaid doesn't last forever: every province and territory sets a deadline to sue, and once it passes the borrower can have the claim dismissed as "statute-barred" — no matter how clearly the money was owed. The principle is national; the length is provincial.

The mechanics are broadly the same wherever you are. For a loan with a fixed due date, the clock starts when a repayment is missed. For a demand loan (repayable "on demand," with no set date), it generally doesn't start until the first failure to repay after you've actually demanded the money — so a demand loan can sit dormant for years, then run its full period from your demand. And the clock can usually be reset: a written acknowledgment of the debt (an email or text often counts) or a partial payment restarts it — but only if that happens before the period expires. Once a claim is statute-barred it can't be revived — appellate courts have been firm on that point (see, for example, the Ontario Court of Appeal in Michel v. Spirit Financial, 2020 ONCA 398). The period and these reset rules live in each province's Limitations Act — or, in Quebec, the Civil Code — so the one that governs is wherever you'd file.

The practical lesson is identical in every province: silence is expensive. If a relative stops paying and you let it slide to keep the peace, the window can close on you. If it does come to enforcement, the venue is usually small claims court — but the dollar limit and even the court's name vary widely — from $15,000 in Quebec and Manitoba up to $100,000 in Alberta, with British Columbia sending its smallest claims to an online Civil Resolution Tribunal. Our province-by-province suing-for-an-unpaid-loan guides have the local detail, and the softer-first options are in what are my options if family won't repay?

The legal steps, in order

Put together, lending to family legally is a short, ordered process. None of it requires a professional for an ordinary loan.

1. Decide gift or loan — on purpose. If you expect repayment, it's a loan; commit to that before any money moves. Not sure? Use the 60-second tool.
2. Agree the terms out loud. Amount, when and how it's repaid, and whether there's interest. Aligning expectations now prevents most disputes later.
3. Write it down. A clean agreement with both names, the amount and date, repayment terms, any interest, and a line stating it's a loan — not a gift.
4. Both sign. E-signatures are valid, so it can be done from two phones in different cities.
5. Keep your proof. Save the signed agreement and a record of the transfer. This is what makes the loan enforceable if it's ever questioned.
6. Know your enforcement path. If repayment stalls, act before the limitation window closes — a written acknowledgment can buy time, and small claims court is the usual venue.
