Hopped over to the Sobeys website and saw a link to a telephone scam involving iTunes gift cards:

A number of Canadians, particularly the elderly, have been receiving fraudulent calls from individuals purportedly from the Canada Revenue Agency instructing them to purchase iTunes gift cards as payment for the funds required.

If you suspect you may have been a victim of fraud, please report it to your local police and the Canadian Anti-Fraud Centre immediately.
