Canada (AG) v PHS Community Services Society

 is a leading Supreme Court of Canada case dealing with the application of the criminal law and healthcare heads of power found in section 91 and section 92 of the "Constitution Act, 1867" and the principles of fundamental justice in section 7 of the "Canadian Charter of Rights and Freedoms".
Background.
In September 2003, the Vancouver Coastal Health Authority and the Portland Hotel Society opened Insite, North America's first supervised drug injection site, in Downtown Eastside Vancouver, an area of high drug use. s 4(1) and 5(1) of the "Controlled Drugs and Substances Act" ("CDSA") prohibited the possession and trafficking of controlled substances, and so in order to operate, Insite was obligated to apply for an exemption for medical and scientific purposes from the "CDSA". The federal Minister of Health, whose discretionary powers under s 56 of the "CDSA" permitted the granting of exemptions, allowed Insite's application. Insite received further extensions on their exemption in 2006 and 2007. In 2008, Minister of Health Tony Clement failed to extend the exemption, casting doubt on Insite's ability to operate the facility in the future. In response, Insite launched a court challenge against the federal government.
The courts below.
At trial before the Supreme Court of British Columbia, Insite argued that s 4(1) and 5(1) of the "CDSA" were inapplicable to Insite because of the interjurisdictional immunity granted them as a health facility. Insite argued that applying the "CDSA" provisions to their facility in the absence of an exemption would violate their s 7 rights upon application. In the alternative, Insite argued that the Minister of Health had violated their s 7 rights by failing to extend the exemption. The trial judge rejected Insite's interjurisdictional immunity argument, noting instead the primacy of double aspect in Canadian constitutional law. However, the trial judge found that s 4(1) and 5(1) of the "CDSA" violated Insite's s 7 "Charter" rights because they "arbitrarily prohibited the management of addiction and its associated risks", and they could not be saved by s 1 of the "Charter". The trial judge thus granted Insite a constitutional exemption and issued a suspended declaration of invalidity regarding s 4(1) and 5(1) of the "CDSA".
Upon appeal by the federal government to the British Columbia Court of Appeal, the majority of the court affirmed the trial judge's decision, agreeing with the result of the trial judge's "Charter" and interjurisdictional immunity analyses.
Decision of the Supreme Court.
The court unanimously dismissed the appeal and cross-appeal on the basis of a s 7 argument, although it found no division of powers flaw in the "CDSA".
Division of powers.
The court found that s 4(1) and 5(1) of the "CDSA" were valid exercises of the federal law criminal power, per "R v Malmo-Levine", where the court held that "protection of public health and safety from the effects of addictive drugs is a valid criminal law purpose". The court rejected the respondents' argument that the provinces could be exempt from the federal criminal law power if they established an activity serving the public interest. The court ruled also that interjurisdictional immunity could not shield the provinces from the federal criminal law power, given the narrowing of that doctrine in the Supreme Court's ruling in "Canadian Western Bank v Alberta". 
This restraint arises from the SCC's 2010 ruling in "Quebec (AG) v Canadian Owners and Pilots Assn", where three related concerns were identified with the doctrine:
The Court further held that the delivery of health care services does not constitute a protected core of the provincial power over health care, because:
As McLachlin CJ noted,
Section 7 of the "Charter".
The court found that s 4(1) of the "CDSA" engaged s 7 of the "Charter" but operated in accordance with the principles of fundamental justice. Although that provision touched upon Insite users' life, liberty and security of the person by prohibiting drug possession at Insite, the s 56 exemption prevents s 4(1) of the "CDSA" from acting arbitrarily, overbroadly or grossly disproportionately upon Insite users.
However, the court found that the Minister's failure to grant the exemption limited Insite users' s 7 "Charter" rights and breached the principles of fundamental justice. The failure to exempt Insite was arbitrary because it undermined the "CDSA"'s purpose; namely, the "maintenance and promotion of public health and safety". The failure was also grossly disproportionate in that it denied Insite's services, which had not had any "discernable negative impact on the public safety and health objectives of Canada during its eight years of operation".
While the court did not consider whether the Minister's failure to grant an exemption could be saved by s 1 of the "Charter", they found that there would have been no rational connection between the Minister's failure to grant the exemption and the "CDSA"'s stated purpose.
The court exercised its s 24(1) "Charter" power and ordered via mandamus the Minister to grant Insite the exemption. The court noted that the Minister ought to grant future exemption requests when the injection facility would "decrease the risk of death and disease, and there is little or no evidence that it will have a negative impact on public safety".
