Are verbal agreements enforceable in Ontario

Some agreements can be enforceable even when they were never put into a formal written contract. The result depends on the subject matter, legal requirements, and evidence of the terms. Certain transactions do require writing or other formalities.

Collect messages, transfer records, invoices, witness information, and evidence of what each side actually did. Identify the price, work, payment date, and other terms that were agreed. A later disagreement may concern the existence of a contract or the meaning of a particular term. Avoid adding details merely because they now seem reasonable. A clear account should separate what was expressly agreed from assumptions. Written confirmations made at the time can be particularly useful when the parties remember the conversation differently.

Write down the conversation chronologically and identify the terms each side says were settled. Who made the offer, how was it accepted, what was to be provided, and what payment or other exchange was promised? Later conduct can help explain the arrangement, but it should not be used to invent a term that was never agreed. Keep original messages and records of performance. If another person heard the conversation, note what that person directly remembers rather than asking them to adopt your reconstruction.

The subject matter must also be checked for legal formalities and statutory protections. A principle about an ordinary service agreement should not be applied automatically to a land transaction, guarantee, or regulated consumer contract. If there is a written document covering part of the arrangement, provide it for review alongside the alleged oral terms. A practical claim needs both a supportable agreement and proof of breach and loss. Clear evidence of the terms often matters more than repeating that a verbal contract is just as good as a written one in every situation.
