Celebrating 201 Years

In 1817, the Montreal Bank became Canada’s first bank, and went on to play a critical role in the building of a nation, its financial systems, and the prosperity of its people.


We invite you to explore some of the stories from the past 201 years that trace the growth of BMO Financial Group and our continuously evolving relationship with customers.


We’re here to help for all life’s moments, no matter how big or small.
