The Toronto Globe & Mail published a very comprehensive article on all the various places that unclaimed property hides north of the border. The article provides information for unclaimed property databases maintained by the Bank of Canada (unclaimed bank accounts), Canada Revenue Agency (unclaimed tax refunds), the Office of Bankruptcy, even the Ontario Lottery Commission.
As in the U.S., the regulation of unclaimed property in Canada is generally a matter of local (provincal), as opposed to federal, law and differs from province to province. Some provinces, such as Quebec and Alberta, have fomalized unclaimed property laws and online databases. In other provinces, such as British Columbia, the laws are mandatory for some holders, but optional for others.
If you have information concerning unclaimed property laws in other Canadian provinces, feel free to drop us a line.
