Smoking in Canada
Smoking in Canada is banned in indoor public spaces and workplaces (including restaurants, bars, and casinos), by all territories and provinces, and by the federal government. As of 2010, legislation banning smoking within each of these jurisdictions is mostly consistent, despite the separate development of legislation by each jurisdiction. Notable variations between the jurisdictions include: whether, and in what circumstances ventilated smoking rooms are permitted; whether, and up to what distance away from a building is smoking banned outside of a building; and, whether smoking is banned in private vehicles occupied by children.
