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, signed promise to repay a specific sum either on demand or at a fixed or determinable future time, while a demand note is a promissory note that’s payable whenever the lender formally demands payment rather than on a set due date; key terms usually include the principal, interest (if any), the parties, and repayment conditions, and Bills of Exchange Act, R.S.C. 1985, c. B-4 defines core requirements.   For help reviewing, drafting, or enforcing a note and protecting your rights across Ontario, SFG Paralegal Services LLP Paralegal offers clear, cost-effective support; call (888) 398-0121 to get started.

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, addresses promissory notes as a form of financial instrument, along with currency, cheques, among other things, and specifically 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.

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.  In Ontario, “licensed paralegals” are governed by the same Law Society that supervises lawyers, and they possess the authority to represent clients in specified litigation concerns.  Advocacy, legal interpretation, and procedural expertise are fundamental to that responsibility.  SFG Paralegal Services LLP provides legal representation within its licensed framework, focusing on strategic positioning, evidence preparation, and compelling advocacy aimed at securing effective and advantageous outcomes for clients.
