Do I have to treat a demand note differently than a common promissory note when it comes due in Ontario?
In Ontario, Caruso Legal Services can help you understand how a demand note differs from a common promissory note: a promissory note is an unconditional written promise to pay a sum certain, signed by the maker, and can be payable at a fixed future time or upon demand of payment under Bills of Exchange Act, R.S.C. 1985, c. B-4, s. 176(1). A demand note is a promissory note with no specific due date, so the amount typically becomes due when the holder makes a valid demand for repayment, while a common (time-based) promissory note becomes due on its stated due date. If you are dealing with a lender or borrower about timing, interest, or enforcement, call (289) 271-0488 to get clear next steps from a paralegal at Caruso Legal Services.

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, 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
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 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.
