Like most foods, as long as the general food safety requirements are met, along with additional requirements specific to that particular type of product, alcoholic beverages can be legally sold in Canada and they don't need to have a pre-market assessment or an approval from Health Canada.
At the federal level, Health Canada regulates alcohol under the Food and Drugs Act. It includes things like standards of identity for specific categories of alcohol, such as beer, cider, whisky, rum, gin, different types of spirits. It can include permissible ingredients that are allowed in those products, methods of manufacture, and certain labelling requirements, such as common name, quality, and alcohol by volume. The act also contains general prohibitions against deceptive marketing of foods, which also applies to alcoholic beverages.
On the other hand, the provinces are responsible for enacting laws and regulations regarding the sale and distribution of alcoholic drinks within their jurisdiction. Alcohol oversight is usually managed by the provincial liquor control boards or commissions. They can set out additional health and safety labelling regulations related to alcoholic beverages. They also have the authority to control accessibility through pricing, licensing of outlets, hours of operation, and setting minimum drinking ages.
