The Information and Privacy Commissioner of Alberta has ruled that Home Depot violated the Personal Information Protection Act (Alberta) when it collected and recorded a customer drivers license information in connection with a product return. The company's policy was that returns for purchases that were made with a debit card, even with a receipt, are treated as a "no receipt" return and the information is collected. The Commissioner noted that the information would be placed in a database maintained by the American parent company in the United States, which is a disclosure of personal information.
The article on Canada.com quotes a Home Depot spokesperson who says this is no longer the policy as customers thought it to be an invasion of privacy. See: Privacy commissioner raps Home Depot.
