Question: why bmo and not bom?
Answer: Why is the Bank of Montreal's logo "BMO" instead of "BOM"? It's based off the French name, Banque d'MOntreal. ... BMO stands for "Banque de Montréal". The word "Banque" is abbreviated as "B", the word "de" is not in the abbreviation, and the word "Montréal" is abbreviated as "MO".
