Understanding Implied Warranties

The difference between express and implied warranties under Canadian law

Last verified: 2026-04-04

The Concept of an Implied Warranty

An implied warranty is a condition that the law reads into a contract automatically, whether or not the parties agreed to it explicitly. Implied warranties exist to protect consumers from defective or misdescribed goods where the parties have unequal knowledge or bargaining power.

In Ontario, the Sale of Goods Act and the Consumer Protection Act, 2002 together create a robust framework of implied warranties that cannot be contracted out of in consumer sales.

The Three Key Implied Warranties

The Sale of Goods Act implies three main conditions into every contract of sale by a business: that the goods are of merchantable quality, that they correspond with their description, and that they are reasonably fit for any particular purpose made known by the buyer. Together these cover the most common complaints consumers have about defective goods.

Merchantable quality means fit for the ordinary purposes for which such goods are used. Correspondence with description covers mislabelled, miscategorized, or misadvertised goods. Fitness for purpose applies where the buyer told the seller about a specific intended use and the seller's judgment was relied on.

Enforcement and the CPA Anti-Waiver Rule

Section 9 of the Consumer Protection Act, 2002 provides that the implied conditions and warranties under the Sale of Goods Act apply in consumer transactions 'notwithstanding any agreement to the contrary.' This prevents a supplier from using fine print in a contract to contract out of the protection. Implied warranties apply alongside any express warranty.

Enforcement is typically through a written demand to the supplier followed, if necessary, by a civil claim in Small Claims Court. The limitation period is two years from discovering the breach under the Limitations Act, 2002.

When to Consult a Consumer Protection Lawyer

This platform is designed to help individuals understand their rights as consumers in Canada. Many aspects of navigating consumer issues can be navigated independently with the right information.

The most effective time to engage a consumer protection lawyer or licensed paralegal is before a contract dispute, when responding to a refund refusal, when facing collection agency harassment, or when a matter involves complex legal issues such as deceptive practices, warranty enforcement, or class action proceedings.

By gathering documentation and understanding the relevant statutes first, consultations become focused strategic reviews rather than costly fact-gathering sessions.
