The action by provincial authorities is neither contemplated nor authorized by the CDSA. The minister is not inserting herself into provincial services. She is not asking that these be set up or not set up. The provinces and the local authorities can work towards that goal.
Ultimately the minister must decide if the exemption to the criminal law power is in accordance with public health and public safety goals that underlie the reasons for the CDSA and whether granting that exemption or not is also in keeping with section 7 of the charter.
