Canada (Attorney General) v. JTI-Macdonald Corp., et al.

Tobacco companies challenged the constitutionality of a Canadian law increasing the size of tobacco warnings from 33% to 50% of the pack, as well as banning lifestyle advertising and promotion; advertising to young people; false or misleading advertising; and sponsorship. The Supreme Court upheld both the warning label requirements and the advertising bans, holding that public health outweighs the companies' freedom of expression.
