Although the Cannabis Act allows for the legal use of cannabis, provinces, and territories are allowed to enact restrictions and regulations regarding the sale, distribution, and use of cannabis. For example, each province and territory set its own procedures for retail sales, and these vary as to ownership or retail outlets (by the provincial government or private enterprise) but all include an option for online sales.

While each household is allowed to grow up to four cannabis plants from “licensed seed or seedlings”, Quebec chose to be excluded from this aspect of the legislation so it is not legal in the province. Manitoba permits home growing only with a medical license.

While specific regulations vary among provinces and territories, there are some general rules regarding promotion, packaging, and advertising. Adult-use cannabis can only be sold in packages of a single color without graphics other than the logo and a health warning. Cannabis companies in Canada are not allowed to promote themselves through TV commercials, billboards, or glossy magazine ads, sponsor people or events, or put their names on sports and cultural facilities.
