In the78th minute, Anne hands to Luke a joint which is actually an unlit cigarette. He takes it unlit, inhales to light it, then hands it back to her unlit.
Early in the movie when Anne is speaking with Gloria, in the background the radio announces that since marijuana has been legalized in Canada, there are already lineups at the LCBO (Liquor Control Board of Ontario). Though there was talk of LCBO becoming a legalized distributor of cannabis, they never did do so. Gloria also says that Shoppers (Shoppers Drug Mart, a major drug store chain) sells cannabis. Again, there was talk of SDM distributing it, but they only distributed marijuana designated for medical-use.
In the beginning of the movie Anne is in her kitchen speaking with Luke, a police constable. He is wearing Metro Toronto Police Service patches on his shoulder, but otherwise is missing his chest insignia including a name badge and the word 'police.'
The badge on Luke's cap does not match the Toronto Police Service patches show on his shoulders earlier.
