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 written, unconditional promise to repay a specific sum either on a set date or on demand, while a demand note is a promissory note with no fixed due date and becomes payable when the lender requests payment; these notes are governed in Canada by Bills of Exchange Act, R.S.C. 1985, c. B-4.

Understanding What Constitutes As a Promissory Note and What Is Meant By a Demand Note Versus a Common Note
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
Usual terms that may be shown upon a note include the principal amount due, the applicable interest rate, the parties to the note including a party who may be unspecified and simply known as a "bearer of note", 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 negotiable instrument and could consist as a cheque, loan agreement, or other document evidencing indebtedness.
NOTE: A large volume of inquiries around “lawyers near me” or “best lawyer in” typically indicates an urgent need for effective legal assistance rather than a search for a particular designation. In Ontario, “licensed paralegals” are governed by the same Law Society that regulates lawyers and are permitted to represent clients in specified litigation issues. Core to their role are advocacy, legal assessment, and procedural expertise. Legacy Legal Services provides legal representation within its licensed framework, focusing on strategic positioning, evidence preparation, and compelling advocacy aimed at securing efficient and favourable outcomes for clients.
