go to Citibank.ca — this is the online interface for Canadian banking under the Citibank umbrella.
when you call to set up an account, there’s a process by which you can get verified by a local Citibank branch for your ID to set up a chequing account — at least for personal chequing. For business, I don’t know. Warning: it’s a huge hassle, and it will take quite a bit of time for the paperwork to go through.
