Equifax Inc. says approximately 100,000 Canadian consumers may have had their personal information compromised in the massive cyberattack on the credit data company made public earlier this month.
The company says the investigation is ongoing and the information that may have been breached includes names, addresses, social insurance numbers and in some cases credit card numbers.
It adds that hackers obtained access to files containing the personal information of some Canadian consumers through one of Equifax's consumer website applications intended for use by U.S. consumers.
Equifax Canada's president and general manager Lisa Nelson apologized to Canadian consumers whose data may have been compromised in the breach.
On Sept. 7, Equifax announced that it suffered a data breach that may have compromised the personal information of 143 million Americans and less than 400,000 U.K. residents.
Canada's privacy watchdog announced last Friday that it was probing the data breach and Equifax has committed to notifying those affected in writing as soon as possible.
