The BoC’s new fear: AI with a side of cybersecurity
The Bank of Canada pulled the country’s biggest banks and financial firms into a meeting about a very 2026 problem: advanced AI models creating fresh cybersecurity headaches. The discussion reportedly centered on Anthropic’s Mythos model, which is basically another reminder that the robots aren’t just writing emails and code — they’re also changing the threat landscape.
Why this matters for banks
If you’re a lender, the fun part of AI is supposed to be faster workflows and smarter customer service. The unfun part is that the same tools can also be used to probe systems, automate attacks, and make old-school security playbooks look like a flip phone.
For Canada’s big banks, that can mean:
- more spending on cybersecurity and monitoring
- tighter internal controls around AI use
- slower adoption of some tools while regulators take a closer look
Not just a Canada problem
This wasn’t happening in a vacuum, either. U.S. policymakers — including Treasury Secretary Scott Bessent and Fed Chair Jerome Powell — reportedly held a similar urgent meeting with Wall Street leaders earlier in the week. Translation: regulators on both sides of the border are starting to treat AI risk like a boardroom issue, not just an IT one.
Big picture
For banks like BMO, this doesn’t scream immediate crisis — but it does hint at a world where AI creates both efficiency gains and a bigger security bill. In other words: the shiny new toy may come with a very expensive lockbox.
