On May 28, 2018, and after the issue had been reported in the media, BMO Bank of Montreal announced that in early 2018, cybercriminals accessed the personal information of approximately 110,000 users of its banking services.

This personal information included users’ names, dates of birth, social insurance numbers, bank account numbers, credit and debit card numbers, and other important identifying information. In some instances, this personal information was made public; it is not known at this time what use has been made of this stolen personal information.

Melissa Mallette - represented by Siskinds LLP, Sotos LLP and Jensen Shawa Solomon Duguid Hawkes LLP - commenced a proposed class action against BMO, in Ontario, on behalf of all clients of BMO whose personal information was accessed in the early 2018 event. The Statement of Claim alleges that BMO breached contractual and statutory obligations it owed to class members.

The opt-out deadline for this class action has now passed.
