A promissory note is the smallest unit of lending paper: one person’s signed promise to repay. It’s valid across Canada — and for family lending it’s usually one signature and several answers short of what you actually want.
A blank promissory note is free everywhere and worth about that. The complete, two-signature version of the same promise is free to draft and $29 to certify.
Strip lending paper to its skeleton and you get the note: “I, [borrower], promise to pay [lender] $X by [date], with interest at Y%.” One signature — the borrower’s — and it’s a recognized debt instrument everywhere in Canada. Banks use long-form versions of it daily. For a quick, small, arm’s-length IOU, a note can be enough.
Family lending isn’t arm’s-length, and its disputes aren’t about existence of the debt — they’re about terms. Was repayment monthly or “eventually”? Was interest agreed? Could the borrower prepay? What happens after a missed month? A bare note is silent on all of it, and silence gets filled by whichever memory is arguing. Worse, only one party signed: the lender’s understanding is nowhere on the page.
That’s why the practical upgrade path isn’t a longer note — it’s a loan agreement: the same promise, plus the schedule, the contingencies, the governing province, and both signatures with a certificate proving who signed and when.
Building the full agreement costs nothing; certifying it with both e-signatures is one $29 fee, the borrower’s by default. If all you truly need is a skeleton IOU, any stationery-store note will do — but if the money matters, complete the promise.
Everything a note does, plus the schedule, the terms, and both signatures.
Create my loan agreement →Yes. A signed note stating who owes whom, how much, and on what terms is enforceable evidence of a debt in every province. Validity isn't the note's weakness — completeness is.
Typically: the borrower's acknowledgment via their own signature alongside yours, a real repayment schedule rather than a bare due date, what happens on a missed payment, prepayment rights, and the governing province. Each gap is a future argument.
Because family disputes are rarely about whether money moved; they're about what the terms were. A document both parties signed proves the terms were mutual, not dictated or misremembered. It also changes behaviour — people honour what they signed.
Lend Right builds the stronger instrument: a full loan agreement, e-signed by both parties, that does everything a promissory note does and closes its gaps. If a court or trustee ever asks for your 'note,' the agreement is that and more — see our guide on notes in consumer proposals.
Who runs this: Lend Right is a product of RULE8 Inc. · Last reviewed July 3, 2026 by the Lend Right Editorial Team.
Based on: the common-law treatment of promissory notes and debt evidence across Canadian provinces; Criminal Code s. 347 (35% APR cap); provincial e-commerce and limitation statutes; Bankruptcy and Insolvency Act proof-of-claim practice for unsecured debts.
What this is (and isn’t): general information from a self-help drafting tool. Lend Right produces loan agreements, not bare notes; nothing here is legal advice and no lawyer-client relationship arises. Quebec’s civil-law regime differs and isn’t yet supported.
On e-signing: electronic signatures are recognized for ordinary contracts in every supported province; the sealed PDF’s certificate records each signer and timestamp — evidence a bare paper note never carries.
Lend Right provides self-help document automation, not legal advice, and no lawyer-client relationship is created. For complex situations, consult a licensed lawyer in your province.
