JTI-Macdonald and other tobacco manufacturers challenged provisions of the Tobacco Act and the Tobacco Products Information Regulations, alleging that such provisions limit their right to freedom of expression under section 2(b) of the Charter of Rights and Freedoms. The Attorney General appealed the decision of the Quebec Court of Appeal, which found parts of some provisions to be unconstitutional. The Supreme Court of Canada allowed the appeal, thus upholding the general ban on the advertising and promotion of tobacco products, subject to specific exceptions for brand-preference and informational advertising.
