Bank of Montreal took over Bank of the West as part of its massive multi-billion-dollar strategic acquisition. Because Bank of the West maintained its historical headquarters and a massive concentration of its retail branches, commercial lending hubs, and deposit accounts within California, this takeover instantly transformed BMO into a major banking player in the California market. Following the legal acquisition and subsequent technical system integration, former Bank of the West branches throughout California were successfully converted into BMO Bank locations, significantly expanding customer access.
