As of October 29, 2026, several major Canadian banks are blocking third-party personal AI agents from directly accessing authenticated banking platforms and client information. The move is drawing attention because it pits convenience-focused AI tools against bank security and account control.

Key facts

October 28–29, 2026: RBC, TD, BMO and CIBC confirmed restrictions
RBC blocks third-party AI agents from authenticated digital properties, including online banking
TD says it blocks all third-party personal AI agents where authentication is required
BMO says AI agents cannot access its digital properties or execute transactions

What happened

Several of Canada’s largest banks have moved to block third-party personal AI agents, including tools like Meta’s Muse, from directly accessing authenticated online-banking platforms and client information.

RBC publicly described its decision on October 28, and broader reporting followed on October 29. TD, BMO and CIBC also confirmed restrictions, while separate reporting said Scotiabank was restricting third-party agents as well.

Why banks are doing this

The banks say the concern is security. They warn that AI agents could expose sensitive information, act beyond a customer’s expectations, create liability, or carry out transactions without adequate authorization.

BMO also warned customers not to share passwords, PINs or verification codes through unauthorized channels, while TD said it is developing safeguards, authorization mechanisms and oversight before allowing broader use.

Who is affected

RBC said it is blocking third-party personal AI agents from accessing authenticated RBC digital properties, including online banking. TD said it blocks all third-party personal AI agents from directly accessing banking information where authentication is required.

BMO says AI agents cannot access its digital properties or execute transactions, and CIBC says it does not support personal AI agents directly opening or accessing accounts. CBC’s reporting identifies RBC as Canada’s largest bank by assets.

What to watch next

The reports do not say these bans are permanent. TD specifically said it is working on safeguards and oversight, which suggests future access could depend on stronger controls and approved authorization methods.

The timing matters because consumer interest in AI assistants is growing, and the bank responses show a current tension between using AI to simplify tasks and keeping financial accounts under direct customer control. The reports do not establish how many Canadians use these agents, only that RBC described the affected group as a small portion of its clients.
