Most terminals in large Canadian cities support NFC payments with credit cards so once this is in place I can see it being adopted rapidly.
I was actually surprised, in my travels, to find that Canada's use of NFC (and let's face it, terminal credit card and debit card payments in general) to be so wide-spread compared to other countries. Haven't been the Japan yet - where there use is probably higher.
I rarely have to carry cash anymore. Was kind of shocked to find that a lot of places in NYC still are cash-only.
All that to say: yeah, we're ready for Apple Pay. Technically speaking, anyway.
