The Canadian legislation
• Defines what is a Private Information
• You shall be secure
• Your security should be reasonable
• An Act Respecting the Protection of Personal
Information in the Private Sector (Québec)
• Personal Information Protection Act (Alberta & BC)
• Personal Health Information Protection Act (Ontario)

True Story – the facts
Two persons enter the store and select merchandise
worth almost $8,000. They hand a credit card to the
cashier who then swipe the card. The card is rejected
by the cash register’s computer. The card holder
indicates that the rejection was expected and that the
casher should contact the credit card company by
phone to receive a payment approval confirmation
code. The card holder gives the credit company’s
phone number to the clerk who calls the company.
The company approves the purchase and provides a
confirmation code. The merchant was never paid.
