International students can apply for a credit card. I just received a notification asking me to pick it up. CIBC has a credit card specifically for international students
It is not necessary to have a credit card here to get a debit card. There are two accounts that can be used to pay with credit cards. To put it bluntly, a storage account and a consumption account. When you save money, you will be asked which account you want to deposit it in.
Some banks will ask you to pay a deposit and how much. The overdraft limit is determined by the amount, and some require a deposit of 500 dollars, which will be returned after one year.
My class's CIBC does not require a deposit, so I can overdraft 500 dollars. It seems that it is still 700 dollars. I forgot, but there is no problem. Don’t worry, it can be done~
