Signing a contract usually binds you. But a deal that is grossly unfair, made when you had no real choice, may not be enforced.

A contract can be set aside as unconscionable when it is grossly unfair and one side took advantage of an inequality of bargaining power.
The Supreme Court of Canada, in Uber v. Heller (2020), said a contract is unconscionable if there was an inequality of bargaining power and the result was an improvident (unfair) bargain.

Ontario's Consumer Protection Act also lets consumers cancel agreements made through unfair practices, including unconscionable representations, often within one year.
