BMO Bank handles Power of Attorney registrations in person at the branch — there's no mail or phone submission option — and the process has a few quirks that catch caregivers off guard, including a common affidavit requirement and a policy that may limit accounts to just one attorney-in-fact even when a POA names multiple agents. This guide walks you through the full branch appointment process for BMO deposit accounts, from choosing the right branch and preparing your documents to testing every access channel before you leave. It also clarifies the critical distinction between BMO Bank branch accounts and BMO Alto, which is a completely separate product with its own process.
