Ontario's privacy commissioner says she's very concerned about the impact of a privacy breach involving as many as 2.4 million voters after memory sticks containing their personal information vanished from an elections warehouse.
Ann Cavoukian said Wednesday that the breach is the largest and most serious she has seen during her 25-year tenure.
The head of Elections Ontario says two memory sticks went missing in April containing copies of personal information collected from up to 2.4 million voters in up to 25 districts in Ontario.
Greg Essensa says the data wasn't encrypted, contrary to the agency's policy. It can't locate the sticks, which were not stored in their proper location.
The Ontario Provincial Police and the privacy commissioner are investigating.
