Police and prosecution services in all Canadian jurisdictions are currently capable of pursuing criminal charges for cannabis marketing without a licence issued by Health Canada. The Supreme Court of Canada has held that the federal Parliament has the power to criminalize the possession of cannabis and that doing so does not infringe upon the Canadian Charter of Rights and Freedoms. The Ontario Court of Appeal and the Superior Court of Ontario have, however, held that the absence of a statutory provision for medical marijuana is unconstitutional, and to that extent the federal law is of no force and/or effect if a prescription is obtained. The recreational use of cannabis has been legalized by the federal government, and took effect on 17 October 2018.
