Contact the local police or RCMP and let them know what is missing.

Inform your financial institutions immediately of any missing credit cards, debit cards and/or cheques. If you are missing retail credit cards, notify the customer service or credit department of those retail companies as well. Find out your credit card company's liability policy. Learn about debit card fraud and the extent of your liability for unauthorized debit card use. The Alberta government-in partnership with law enforcement agencies, consumer groups and the private sector-has developed a universal identity theft statement, which can be used by victims to notify most major creditors of what has happened

It may not seem as important to replace these cards quickly, but they are also open to misuse. The sooner you deactivate any missing cards bearing your name, the better.
