Hello! I just wanna ask if what should I follow? When I entered Canada, there's an APC or Automated Passport Control Machine (Kiosk), I entered 90 days, the port of entry ask me of my stay too and I said 3 months but I have 6 months visitors visa, and also my visa doesn't have any stamp. Should I stay for 90 days or Can I stay for 6 months? Thanks for the answer 
Godbless
