Maybe not as secure from that standpoint, but we do have the most economically stable banking system of all G8 nations.
Which one did your ex work for? If it was CIBC, TD/Canada Trust or ScotiaBank I can easily believe you. I'm with Royal Bank of Canada, they've had the highest online security rating in Canada, one of the higest in the G8, for a few years now. About 5 years ago some hacker managed to get in and do something, after that they got serious about it and have had top ratings since.
