OTTAWA - The Canada Revenue Agency is warning people to beware of scam artists trying to steal personal financial information with a letter purporting to be from the government.

The phoney document uses an authentic-looking letterhead and claims that people are missing out on refunds because certain information was omitted from their returns.

It asks them to send key information, including bank account numbers, to an email address or a fax number.

The revenue agency says don't fall for it.

Police have been notified.
