With a date officially set for legalized marijuana in Canada, Windsor's Police Chief says the hard work now begins.
Al Frederick says four months isn't much time to hammer out the details surrounding regulation and enforcement.
He says there's still a lot of unanswered questions when it comes to driving under the influence.
"We think there's many pieces of a complex puzzle that are not in place yet. There's tools out there for the testing of breath when impaired by drugs. However, none of those have been approved. So the government needs to move quickly on remedying that."
Frederick says impairment testing could be a challenge.
"THC can stay in different people's systems at length. So they may not be impaired, but they still have it in their system. Those are complicated that I think the medical field and the scientific field need to address so that when people are stopped we can find out if they're impaired or not."
He says police have been left in the dark on many aspects.
"We don't know a lot about the regulations. So regulations regarding possession or growing it in your home. That stuff has not been ironed out yet. So here we are and we're still waiting to know how are we going to enforce other aspects of possession or inhalation of cannabis."
Frederick adds, up to this point, his department has done everything it can to be ready for legalized weed including additional officer training and bringing in experts on the issue.
On Wednesday, Prime Minister Justin Trudeau announced recreational marijuana will be legal in Canada as of October 17.
