Not sure how it is where you’re from but don’t get caught thinking because Canada is safe that you can be careless with your stuff, don’t let your guard down with personal belongings. Don’t leave your things unattended in cafes or shops, don’t leave your mobile phone on the table, and especially don’t leave anything in your car if rent a car. Canada is safe but there is still a lot of petty theft… you won’t get mugged but someone might try to swipe your backpack at a cafe when you aren’t looking.
