в каждом регионе и области свои правила. Вот на Монреаль. важно - где можно курить, и какое колличество иметь при себе разрешается. еще хорошо прочитать такую инфо про каждый город куда потом едут.

"Every province and territory in Canada has its own laws surrounding the sale, possession, minimum age of use and public usage of cannabis. Seeing as there are 13 of them in total, we won’t go into the nitty-gritty of what’s allowed where by who and when and what the product can be, but what we can say is that you should make sure you’re informed before going elsewhere."
Удачи....
