You might think the title is just to get your attention but it is actually true. In Canada if a bank account is declared inactive then the money is transfered to the Bank of Canada for safe keeping. All the information for the bank account is recorded (name, location, branch and date) and the information can be searched online via the Bank of Canada site. I found this site years ago and a recent article in MoneySense Magazine reminded me of it. I suggest you give it a try. My name turned up nothing but I found a few accounts listed under relatives. I hope they consider my email about it there Christmas gift.
Just my 2 cents on the topic of money.
