Canadian police services told the Canadian government there is no possibility they will be ready to enforce nationwide social cannabis laws next summer.

The letter was sent by the Canadian Association of Chiefs of Police and requested the federal government delay the July 1, 2018 implementation of social cannabis.

Representatives from the association and other precincts said they need more time to properly train officers on the new laws and will be forced to double the amount of officers certified to conduct roadside tests for drugged-driving.

When the representatives appeared before a Parliament health committee which studied PM Justin Trudeau’s bill to make social cannabis legal nationwide, they also requested the government to reconsider a clause which allows individuals to grow cannabis at home. They said homegrown cannabis would be difficult to police and could make it easier for children to consume it.

Bill Blair, the parliamentary secretary to Canada’s minister of justice, said he respects what the law enforcement officials said and listened to their concerns.

“We can’t allow the status quo to remain because it’s unacceptable,” Blair said. “We have the highest rates of cannabis use in the world. The entire cannabis market is controlled by criminal enterprise.”
