Laws
Federal 
The former Tobacco Act was originally enacted in 1997 in response to the national public health problem posed by tobacco use. Following this, The Tobacco and Vaping Products Act (TVPA) was enacted on May 23, 2018, to regulate the manufacture, sale, labelling and promotion of tobacco products and vaping products sold in Canada.
In Canada, the 1997 federal Tobacco Act makes it an offence to sell or supply tobacco to anyone under the age of 18 or to sell individual cigarettes.
In 2009 and 2015, Health Canada banned the use of certain additives, including flavours like chocolate and bubble gum, in all cigarettes, blunt wraps and most cigars (including little cigars) with the exception of menthol. In 2017, menthol flavours were banned from tobacco products.
Provincial
In 2020, Bill 182 amended the former Tobacco Act to become the Tobacco and Vapour Products Act, aligning tobacco and vaping products in terms of legislation.
The main legislative and regulatory provisions include the following.
No smoking/vaping in, enclosed public places, school grounds, near doorways and windows
• Restrict smoking and vaping in enclosed public places, including schools and school grounds.
• Prohibit people from smoking and vaping within three metres from a doorway, window or air intake of an enclosed public place.
Restrictions on the retail sale, advertising and promotion of tobacco and vapour products
• Restrict the sale of tobacco and all vapour products to individuals 18 years of age and older.
• Prohibit the display of tobacco and vapour products where young persons have access.
• Prohibit the sale of tobacco and vapour products at specified facilities such as amusement parks, arcades and theatres where youth frequent.
• Restrict advertising of vapour products in the same manner as tobacco products by prohibiting advertising signs and promotional signs in areas where young persons can enter.
