St. Clair College has updated its smoking, alcohol and substance use policy.
Spokesperson John Fairley says the use of recreational marijuana will not be allowed on campus.
"I think it's interesting that out of the 24 colleges, we've probably aligned ourselves with the majority of all the colleges that are not allowing the use of recreational marijuana," says Fairley. "So it's not like we're doing something so different than any other colleges are going to do. There's a couple that have allowed it in designated smoking areas."
The updated policy states, college employees are not allowed to use marijuana before or during work hours including paid or unpaid breaks and lunches.
It also says students living in residence (who are legal age) are allowed to carry up to 30g of marijuana in a sealed and labelled container while in residence.
