The legal drinking age in Canada varies by province and territory. It is either 18 or 19 years old depending on where you are:

• In Alberta, Manitoba, and Quebec, the legal drinking age is 18 years.
• In all other provinces and territories, including Ontario, British Columbia, and Nova Scotia, the legal drinking age is 19 years.

This means you must be at least 18 or 19 years old to legally purchase and consume alcohol, depending on the specific province or territory you are in Canada.
