In Canada, it's more like a chequing account, though yes you do get a savings account as well. American Express isn't a good idea, I hold a american express card issued in India (not the travelers card, actual credit card) and acceptability was an issue in India and is an issue in Canada. Scotia bank will issue you a visa card with a limit of 500 CAD and I would say open an account with TD or CIBC, if you are going to deposit 10k CAD with either of the bank, you will have better usage as compared to Scotia. But anyhow, you will have to open an account with Scotia, keep it as reserve account.
Cheers!
