Two Canadian banks warned customers on Monday morning that the personal and financial information of at least 40,000 clients was accessed by criminals.

The affected banks are Simplii Financial—a recently-created brand owned by banking giant CIBC, and which formerly operated as President’s Choice Financial, a grocery store brand—and the Bank of Montreal (BMO). Simplii Financial reportedly has over two million customers, and BMO has more than 12 million clients across its services.
