Five Key Steps to Reduce the Risk of Identity Theft

Identity theft is one of the fastest growing crimes and it can affect everyone, including you. Protect your personal information from being at risk.

Identity theft involves the unauthorized collection and use of your personal information, including your name, date of birth, address, credit card, Social Insurance Number and other personal identification numbers, usually for fraudulent purposes.

They also mention that if you have had any problems with identity theft to contact Equifax Canada and TransUnion Canada right away.

All of the following provinces have their own consumer protection agencies at the Province government level. If you suspect that you're a victim of identity theft, check out your provincial Justice Department - Consumer Protection.
