Promissory Notes:
Negotiable Instruments Containing Express Terms Regarding Repayment
Last Updated: August 22 2026
Question: Is a demand note the same as a promissory note, and when can a lender demand payment in Ontario?
Answer: In Ontario, a promissory note is an unconditional written promise to pay a specified sum to a named person or bearer on demand or at a fixed or determinable future time, while a demand note is a promissory note with no fixed due date and becomes payable when the issuer makes a payment request. Under Bills of Exchange Act, R.S.C. 1985, c. B-4, the note must be a signed, written promise to pay a sum certain on demand or at a set time, and typical terms include principal, interest (if any), parties, issue date, and repayment terms.

Understanding What Constitutes As a Promissory Note and What Is Meant By a Demand Note Versus a Common Note
A promissory note is a legal document that binds one party (the issuer) to pay a specified amount of money to another party (the payor). The payor is legally obligated to make payment at the predetermined time or upon receiving a demand for repayment from the issuer. A promissory note will detail any applicable terms, including the rate of interest, if applicable, that may be accrued.
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, where the borrower agrees to pay a certain amount of money to the lender at a specific time and under certain conditions. A bank note is a type of promissory note issued by a bank or other financial institution; but, it is backed by the assets of the bank which makes a bank note more secure than a regular promissory note.
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 a type of promissory note but differ whereas a demand note lacks a specified due date and instead becomes due upon request 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.
NOTE: A substantial array of online searches for “lawyers in my vicinity” or “top lawyer in” frequently indicates an urgent requirement for competent legal assistance rather than a particular professional designation.
