You must be at least 19 years old to buy cigarettes in Ontario as of 2026.

Quick Scoop

  • The minimum legal age to buy or be sold tobacco (including cigarettes) in Ontario is 19.
  • This rule comes from Ontario’s Smoke‑Free Ontario Act, which makes it illegal for anyone to sell or supply tobacco to a person under 19.
  • Retailers are required to check ID for anyone who appears under 25, and they can be fined if they sell to underage customers.

A bit of context

Across Canada, the federal minimum is 18, but most provinces, including Ontario, have chosen 19 to add an extra layer of youth protection. Some places like Prince Edward Island have gone even higher to 21, reflecting a trend toward stricter tobacco laws.

In practice, if you’re in Ontario and not yet 19, stores are legally required to refuse selling you cigarettes or other tobacco products.

TL;DR: In Ontario, you need to be 19 or older to legally buy cigarettes.
