BMO Harris Bank is the U.S. commercial and retail bank subsidiary of Bank of Montreal, built up through decades of acquisitions of Chicago-area and Midwest banks — culminating in the 2011 Marshall & Ilsley deal and the 2023 Bank of the West acquisition, which extended its footprint into the U.S. West and made it the 15th-largest U.S. bank by assets. In 2024 the U.S. entity was rebranded from 'BMO Harris' to simply 'BMO' (legal name BMO Bank, N.A.), consolidating the parent group's global identity. As a full-service national bank it operates its own charter, card issuance, and payments infrastructure rather than relying on BaaS providers.
