About BMO Bank
BMO Bank, N.A. is the U.S. subsidiary of Bank of Montreal (the “BMO” in BMO Financial Group), one of the largest banks in North America. The U.S. bank is headquartered in Chicago, Illinois, and operates over 600 branches and approximately 1,300 ATMs nationwide.
The bank traces its roots to 1882, when Norman Wait Harris founded N.W. Harris & Co. in Chicago. Through more than a century of growth and acquisitions — including Bank of Montreal’s acquisition of Harris Bank in 1984, the 2011 acquisition of Marshall & Ilsley (M&I) Corporation, and the 2023 acquisition of Bank of the West — BMO has grown to become the 15th-largest U.S. bank by total assets. The Bank of the West deal added 1.8 million customers and roughly 500 branches across the Western U.S.
In 2023, BMO retired the “BMO Harris” brand and unified all U.S. retail operations under the simpler BMO Bank name. The Harris name had been part of the bank’s identity for more than 140 years — the rebrand reflects BMO’s expansion beyond its Chicago/Midwest roots into a true cross-country bank.
BMO offers checking and savings accounts, certificates of deposit, credit cards, home mortgages, auto loans, personal loans, small business banking, commercial banking, and wealth management.
