Update: On Friday, the Office of the Privacy Commissioner (OPC) of Canada announced that it is launching an investigation into the hack that targeted credit giant Equifax. To date, Equifax has not stated how many Canadians are affected.

Update: On Monday, October 2, Equifax announced that the number of Canadians affected by the hack is 8,000, down from an earlier estimate of 100,000. The total number of affected US individuals also changed, with Equifax stating that 145.5 million people in the US were affected, up from the initially stated total of 143 million.

OPC additionally stated that "at this point in time, it is not clear that the affected data was limited to Canadians with US dealings," although earlier reports had stated otherwise. Equifax has committed to notifying all impacted Canadians in writing as soon as possible, the OPC statement says, and will offer free credit monitoring.

One week after credit firm Equifax revealed a massive hack affecting half of the American population, Canadians are still waiting to hear how many of us are affected.

After announcing the hack on September 7, the credit giant was immediately forthcoming about how many Americans were affected—143 million—but in its initial statement it was incredibly vague on how many Canadians and UK citizens were involved. The company simply said that "limited" information from "certain" UK and Canadian citizens was stolen. On Friday, the Canadian Press reported that the Canadian Automobile Association (CAA) notified 10,000 members who participated in a joint CAA and Equifax program that their data may have been compromised. The program started in March of 2015 and ran until July 1 of this year.
