Bank of the West was officially acquired by BMO Financial Group, marking the completion of a massive cross-border banking integration. Following the legal acquisition, a comprehensive technical system conversion successfully migrated all former Bank of the West customer accounts, routing numbers, and credit lines into BMO's proprietary banking platform. Account holders retained uninterrupted access to their funds, with former physical branches rebranded and integrated into the broader BMO branch network, while online banking credentials, mobile applications, and customer service channels were fully transitioned to the parent institution.
