The bank currently operates more than 220 branches in California.
The planned openings will increase its presence in the state by over 50%, as part of a multi-year development strategy focused on Western US regions experiencing population and economic growth.
BMO stated that the upcoming sites will be designed as centres for financial guidance, bringing together services in personal and business banking, commercial banking, and wealth management.
The aim is to support customers varied financial requirements and improve service access across these communities.
In California, the initial schedule for 2026 includes three branches in Greater Los Angeles, two in the Bay Area, and two in San Diego.
In Arizona, the bank plans to establish approximately 15 new branches over the coming five years, with an emphasis on expanding in the Phoenix and Tucson areas.
BMO indicated that these plans represent a “long-term” investment and are expected to create several hundred jobs within the next five years.
As of 31 January 2026, BMO Financial Group had total assets of $1.5tn, making it the eighth largest bank by assets in North America.
BMO US president Aron Levine said: “Our commitment to our clients and communities is at the core of each decision we make.
“These financial centres provide our clients more opportunity to meet face to face with our teams to discuss their goals for their business and personal financial lives, build trusted relationships, and receive personalised guidance that helps them make real financial progress.”
