Can a demand note be treated the same as a promissory note in Ontario, and when can the lender demand payment?
In Ontario, a promissory note is a written, unconditional promise to pay a certain sum, either at a fixed or determinable future time or “on demand,” and the Bills of Exchange Act defines a promissory note as such an unconditional promise in writing (including payment on demand) in Bills of Exchange Act, R.S.C. 1985, c. B-4. A demand note is essentially a promissory note with no fixed due date, meaning the amount becomes due when the holder makes a formal demand for payment. If you are dealing with whether your document is a true demand note or a common note with a scheduled due date, Legacy Legal Services can help legal professionals and borrowers in Ontario sort out the terms, dates, and who is entitled to payment. Call (226) 246-3825 to discuss your situation and next steps with a paralegal.

Understanding What Constitutes As a Promissory Note and What Is Meant By a Demand Note Versus a Common Note
A promissory note is a written document in which one party (the issuer) makes an unconditional promise to pay a certain amount of money to another party (the payor). Under a promissory note, payment is due at the stated time or upon receiving a request for repayment. A promissory note will include information about any applicable terms, such as the rate of interest, if any, 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. 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 significant number of inquiries featuring “lawyers near me” or “best lawyer in” frequently indicate an urgent requirement for competent legal counsel rather than a particular designation. In Ontario, the same Law Society that supervises lawyers also regulates licensed paralegals, who are permitted to represent clients in specified litigation matters. Central to this role are advocacy, legal analysis, and procedural expertise. Legacy Legal Services provides legal representation within its licensed framework, focusing on strategic positioning, evidence preparation, and compelling advocacy directed at securing efficient and positive outcomes for clients.
