Most business owners would say they do not deceive their customers. But Ontario’s Consumer Protection Act, 2002 defines "unfair practice" broadly enough that ordinary sales enthusiasm, aggressive marketing language, or a rushed conversation with a vulnerable customer can cross a line the business never meant to cross.

Understanding the two general categories of unfair practice, and what a consumer can do once one has happened, helps a business build guardrails before a customer complaint turns into something more serious.

Two Kinds of Unfair Practice

Ontario consumer protection law is generally understood to treat unfair practices as falling into two broad buckets: representations that are false, misleading, or deceptive, and representations that are unconscionable given the circumstances of the specific consumer.

False, Misleading, or Deceptive Representations

This category generally covers claims about a product or service that are not true, even if the seller did not intend to deceive anyone. Common examples include:

Unconscionable Representations

This category is generally understood to focus less on whether a specific claim was literally true, and more on whether the seller took advantage of the particular consumer in front of them, for example:

The unifying theme is the specific consumer’s actual vulnerability and circumstances, not just the objective content of the pitch.

What a Consumer Can Do About It

Where an unfair practice has occurred, a consumer may generally have the right to rescind (cancel) the agreement and recover what they paid, or to pursue other remedies, depending on the circumstances and how long ago the transaction happened. A pattern of unfair practices can also draw regulatory attention that goes well beyond any one customer’s complaint.

Where This Overlaps with Other Rules

Unfair practice rules under Ontario consumer protection law exist alongside, but are legally distinct from, the federal Competition Act’s rules against deceptive marketing practices, which apply more broadly across Canada and are not limited to consumer transactions. A business dealing with a misleading-advertising complaint may need to consider both frameworks, not just one.

Frequently asked questions

Is exaggerated sales language, like calling something "the best in town," an unfair practice?

Generally, obvious opinion or puffery that no reasonable person would take as a factual claim is treated differently than a specific, checkable factual misrepresentation. The closer a claim gets to something specific and verifiable, the more it needs to be accurate.

Can a consumer claim unfair practice just because they regret the purchase?

No. Ordinary buyer’s remorse is not itself an unfair practice. The consumer generally needs to point to a false representation or to circumstances showing the seller took advantage of their particular situation.

Does it matter whether the salesperson intended to mislead the customer?

For the false, misleading, or deceptive category, intent is generally not the central question. What matters more is whether the representation was actually false or misleading, regardless of the seller’s state of mind.

What should we do if a customer accuses us of an unfair practice?

Take it seriously and get legal advice promptly, rather than dismissing it as a difficult customer. How a business responds to the first complaint often shapes whether the issue stays contained or escalates.
