Cooling Off Periods
When you and a contractor sign a contract, it becomes a legal agreement that is binding on both parties and may be enforced through legal action. However, most provinces and territories offer you protection against "high-pressure" door-to-door sales tactics by specifying a cooling-off period (usually 10 days) during which you can cancel a contract without penalty.
However, these laws apply only to contracts signed in your home, and in some parts of Canada other conditions apply as well. So don’t assume you will be able to change your mind after signing a contract, especially if the contract doesn’t include complete information on the work to be done, the price and the schedule.
For more information, contact your provincial Consumers’ Affairs or Protection office and ask about contract “cooling off” regulations where you live.
