Every contract begins with a conversation. Someone proposes something, someone else agrees to it, and an obligation is born. This deceptively simple exchange—offer and acceptance—forms the backbone of contract formation in Canadian law, yet it conceals remarkable complexity that catches business owners off guard every day. Understanding how contracts come into existence, and equally important, how they can fail to materialize despite everyone's best intentions, is essential knowledge for anyone operating a business, running a non-profit, or providing professional services in Canada.
The doctrine of offer and acceptance has developed over centuries in common law jurisdictions, including British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, and the Atlantic provinces. Quebec operates under a civil law framework governed by the Civil Code of Quebec, which codifies similar principles but with distinct terminology and some meaningful differences in application. Despite these structural differences, the fundamental concept remains consistent across Canada: a contract requires a definite proposal by one party and an unequivocal acceptance by another. Without both elements properly aligned, no binding agreement exists, regardless of what the parties believed they were accomplishing.
An offer is more than a casual expression of willingness to do business. It must demonstrate a genuine intention to be bound upon acceptance, contain sufficiently definite terms that a contract could actually be performed, and be communicated to the person who is meant to accept it. The person making the offer, known as the offeror, must intend that their proposal, if accepted, will create legal relations. This requirement of intention filters out social arrangements, preliminary negotiations, and expressions of interest that lack the commitment necessary for contract formation. When a business owner says "we should work together sometime" or "I might be interested in buying your equipment," these statements lack the definiteness and commitment that characterizes a true offer.
