Canada’s police services say there is zero chance they will be ready to enforce new laws for legalized pot by next summer.

Officials from the Canadian Association of Chiefs of Police, Ontario Provincial Police and the Saskatoon Police Service are among dozens of witnesses testifying to the House of Commons health committee this week as it studies the government’s bill to legalize marijuana.

They said Tuesday they need more time to properly train officers about the new laws and more than double the number of police officers who are certified to conduct roadside drug impaired driving testing. There also needs to be more time for public education, the police said.

If the government doesn’t postpone the start date there will be a window of six months to a year when police aren’t fully ready, which will allow organized crime to flourish, said OPP deputy commissioner for investigations and organized crime Rick Barnum.

The police also want Ottawa to reconsider allowing individuals to grow up to four of their own marijuana plants because it will be difficult and expensive to enforce and provide an additional way for young people to get access to pot.

“Why do you need home grows when we’re going to have a good system to access marijuana legally?” asked Barnum.

Barnum said the Canadian Association of Chiefs of Police officially wrote to the government this week to request a delay in implementation. The Liberals have pledged pot will be legal in Canada by the summer of 2018.
