"The role of the federal government is described in key legislation and international conventions and protocols in areas relevant to the Strategy‘s activities. The federal government role in the Strategy is grounded in its authorities under the Constitution Act (1867) as well as key legislation, including CDSA; Criminal Code of Canada; Canada Health Act; Proceeds of Crime (Money Laundering) and Terrorist Financing Act; and Youth Criminal Justice Act. Departmental legislative authorities of relevance include Canada Revenue Agency Act; Canada Border Services Agency Act; Corrections and Conditional Release Act; Department of Foreign Affairs and International Trade Act; Department of Health Act; Department of Justice Act; Department of Public Safety and Emergency Preparedness Act; Department of Public Works and Government Services Act; Director of Public Prosecutions Act; and Royal Canadian Mounted Police Act. International conventions and protocols of relevance include the United Nations Narcotic Drug Conventions and other multilateral processes such as the OAS, the G8, the Paris Pact, and the Dublin Group.
"The federal government plays a critical role in addressing illicit drug issues at the broad policy level. For example, the Department of Justice led on introducing Bill C-10, which included mandatory minimum penalties for serious drug crime, and received royal assent on March 13, 2012. HC [Health Canada] is responsible for amendments under the CDSA to control the movement of certain substances in and out of Canada. This is particularly relevant for controlling and preventing the movement of illicit drugs as well as precursor chemicals which are used to make synthetic drugs (e.g. methamphetamine)."
