BMO Harris Bank
BMO Harris Bank is a major U.S. retail and commercial bank offering checking, savings, mortgages, and investment products.
What is BMO Harris Bank?
BMO Harris Bank traces its American heritage back through a series of mergers but its Canadian parent, Bank of Montreal, was founded in 1817 — making the broader BMO Financial Group one of North America's oldest continuously operating banks. The US operations grew significantly with the 2023 acquisition of Bank of the West, transforming BMO Harris from a Midwest-focused regional bank into a coast-to-coast American banking franchise with a branch network stretching from Illinois to California. The combination created the eighth-largest bank in the United States by total assets.
The digital banking platform — including the bmoharris.com portal and BMO Digital Banking app — handles retail and commercial banking for millions of American customers. The 2023 Bank of the West integration required migrating millions of customer accounts to BMO systems, a technology project of considerable scale that kept integration teams busy through 2023 and 2024. The app supports mobile check deposit, bill pay, account-to-account transfers, Zelle, and loan management. Business banking customers access cash management, wire transfers, and ACH services through the platform. BMO's cross-border banking capabilities — connecting US and Canadian accounts — are particularly valuable for dual-citizen customers and US-Canada businesses.
When BMO Harris's digital systems experience an outage, the disruption affects a customer base that spans legacy BMO Harris customers, former Bank of the West customers still adjusting to the new platform, and business banking clients with time-sensitive cash management needs. Mobile app login failures during recent integration periods created heightened anxiety because customers couldn't always distinguish a platform outage from a migration-related configuration issue. Wire transfer failures for commercial customers can have significant downstream consequences. Mobile check deposit unavailability pushes customers to branches during business hours — a particular inconvenience for the western US customers added through the Bank of the West acquisition who may have fewer nearby BMO branches.
