What are a zero-rated basic grocery products?

Calgary ARGO Customs Brokers: The supply of basic groceries, which includes most supplies of food and beverages marketed for human consumption (including sweetening agents, seasonings and other ingredients to be mixed with or used in the preparation of such food or beverages), is zero-rated. However, certain categories of foodstuffs, for example, carbonated beverages, candies and confectionery, and snack foods are taxable. If a product’s tax status is in doubt, the CRA will consider the manner in which the product is displayed, labelled, packaged, invoiced and advertised to determine its tax status.
