Promissory Notes:

Negotiable Instruments Containing Express Terms Regarding Repayment



Last Updated: June 11 2026

Question: What’s the difference between a promissory note and a demand note in Ontario?

Answer: In Ontario, a promissory note is a signed written promise to repay a specific sum (often with interest) either on a set date or when repayment is demanded, while a demand note has no fixed due date and becomes payable as soon as the lender demands payment; Paladin LLP is a Paralegal service that helps you understand note terms, document repayment expectations, and take practical steps to enforce or respond to a demand across Ontario, call (289) 925-1572 to get started.  If your note’s enforceability matters, confirm it’s in writing, signed, names the payee, states the amount, and clearly sets when payment is due so you can act quickly and avoid costly disputes.

Understanding What Constitutes As a Promissory Note and What Is Meant By a Demand Note Versus a Common Note

Promissory Notes: Negotiable Instruments Containing Express Terms Regarding Repayment A promissory note is a form of negotiable instrument whereby a party (the issuer) makes an unconditional promise in writing to pay a sum of money to another party (the payee).  Payment becomes due under a promissory note at fixed time stated within the promissory note or upon receipt of a demand for repayment. A promissory note will also contain details of any applicable terms such as a rate of accruing interest, if any.

The Law

The Bills of Exchange Act, R.S.C. 1985, c. B-4, governs financial instruments such as currency, cheques, among other things, and defines a promissory note as:


176 (1) A promissory note is an unconditional promise in writing made by one person to another person, signed by the maker, engaging to pay, on demand or at a fixed or determinable future time, a sum certain in money to, or to the order of, a specified person or to bearer.

A promissory note is a contract between two parties, the borrower and the lender.  A bank note is a type of promissory note issued by a bank or other financial institution.  In either circumstance, a promissory note is a written promise to pay a certain amount of money to a specific person or a specific entity at a specific time and under certain conditions.  However, unlike a promissory note, a bank note is backed by the assets of a bank and is therefore more secure.

Terms Upon Notes

A promissory note will typically include details of the principal amount due, the applicable interest rate, the parties involved including a "bearer of note" if a party is unspecified, the date of issue, the repayment terms, and the due date.

Payable Upon Demand

Demand notes are promissory notes without a specific due date as such a note becomes due upon demand of payment.

Summary Comment

A promissory note is a legal document that states a promise to pay a certain amount of money. A promissory note may take the form of a cheque, loan agreement, or other document, that serves as proof of an outstanding debt.
