After all, the cheques go out just a few weeks after people file their taxes. But there are. They pore over phone books, surf the Web, and even check with neighbours. But often, people move and forget to notify anyone, including the tax department. There's no Web-based search engine here, though.
Privacy laws forbid that.
So if you think you've got a refund coming but never got it, contact your local office of The Canada Customs and Revenue Agency for details on how to make a claim. No interest is paid on unclaimed refunds. But there's no charge for the service, and there's no time limit on making a claim. And it's not just income tax refund cheques that we're talking about here. The tax department also has unclaimed GST Credit cheques and Canada Child Tax Benefit cheques.
