A tourist with questions about buses/metro
I am confused about the rules regarding taking transit in Montreal. I will be going there in August and I've never used their public transit system before. I see there are multiple zones and if you go from one zone to another you have to pay a higher fare. I'm wondering if I took Metro Line 2 which pretty much appears to be in Zone A for like 98% of the route but does have a terminus in Zone B do I need a AB fare to ride Metro Line 2 if I'm entering in Zone A and getting off in Zone A on my trip? Also where do I pay for the metro or the bus ahead of time if possible with a credit/debit card?
