About the BMO acquisition and Bank of the West transition
December 2021: acquisition announced
BMO Financial Group announced the acquisition of Bank of the West from BNP Paribas in December 2021, valued at approximately $16.3 billion at the time. The deal was one of the largest U.S. bank acquisitions since the 2008 financial crisis. BMO was already operating in the U.S. Midwest through BMO Harris Bank; the Bank of the West acquisition added the Western U.S. footprint that BMO lacked.
February 1, 2023: acquisition close
BMO completed the acquisition of Bank of the West on February 1, 2023, following receipt of all regulatory approvals in January 2023.

September 5, 2023: brand retirement and systems conversion

Simultaneously, BMO Harris Bank dropped the “Harris” from its name, and the combined bank now operates simply as BMO Bank.
What changed for legacy Bank of the West customers
Legacy Bank of the West customers received new BMO Bank debit cards (mailed in batches over 2023), new BMO-branded checks when ordering replacements, new online banking access at bmo.com (existing usernames were carried over with a forced password reset during the September 2023 conversion), and access to the BMO Digital Banking app (replacing the Bank of the West Mobile app). Most accounts kept their original Bank of the West routing numbers during the transition, with routing numbers eventually consolidating to BMO Bank routing numbers.
Bank of the West redefining banking for a better future
Bank of the West was committed to redefining banking by offering innovative solutions designed to enhance customer financial futures. That commitment continues under the BMO Bank brand, which combines the former Bank of the West Western U.S. footprint with the legacy BMO Harris Midwest footprint into a single 32-state U.S. bank with approximately 1,000 branches.
