You register a company, and wait for operating. So you will need an Business Bank Account. So you will ask the question: which business bank come with cheap fees.
Quick answer: BMO’s eBusiness plan is free, if you do all of your transactions online, and limit your number of eTransfers.
But the true answer is it depends on your volume. Do you pay your vendor by write business cheques or not, do you have a good account manager?(very important). There is no simply answer.
BMO eBusiness Plan offer $0 monthly fee, but when you deposit fund by ATM or issue a business cheque, the cost will be higher.
TD business account could waive the monthly fee, if you maintain some balance in your account. If you located at ON, DUCA might be a better option for you.
