To be honest here it mostly depends on the cop who busts you, ive heard stories of people having up to 14 grams on them and the cops just taking it and letting them go, than stories about people having half a joint and being arrested, its very unpredictable here sometimes.

ps. but where we were in downtown TO we were not harming anyone , we werent making noise really either just sitting there relaxing, a cop did drive by but didnt stop or anything, so im guessing since we were really causing any trouble there wasnt much of a problem
