What is the difference between a promissory note and a demand note in Ontario?
Paladin LLP can help you understand how promissory notes and demand notes work in Ontario, so you can assess when repayment becomes due, what terms may be required, and how a written “unconditional promise to pay” is treated under the Bills of Exchange Act, R.S.C. 1985, c. B-4 (including the definition in s. 176(1)). A promissory note is generally payable at a fixed or determinable future time, while a demand note is due when the holder requests payment because it has no set due date. If you have a document you received or signed and want to confirm its meaning and enforceability, call (289) 925-1572 to speak with a paralegal at Paladin LLP.

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 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 negotiable instrument and could consist as a cheque, loan agreement, or other document evidencing indebtedness.
NOTE: A considerable amount of online inquiries featuring “lawyers near me” or “best lawyer in” typically indicate a pressing need for competent legal assistance rather than merely looking for a specific title. In Ontario, “licensed paralegals” are governed by the same Law Society that regulates lawyers, granting them the authority to represent clients in certain legal disputes. Skills in advocacy, legal reasoning, and procedural expertise are vital to this function. Paladin LLP provides legal representation within its licensed framework, focusing on strategic positioning, evidence preparation, and effective advocacy aimed at securing efficient and beneficial outcomes for clients.
