The Big 5 Banks: Which Is The Biggest Bank in Canada?

RBC is the largest bank in the country and will only become bigger with its recent acquisition of HSBC

The Big Five Banks

The Canadian banking industry is dominated by only a handful of banks known informally as the Big Five.

These are Toronto-Dominion Bank (TD), Royal Bank of Canada (RBC), Bank of Nova Scotia (Scotiabank), Bank of Montreal (BMO), and Canadian Imperial Bank of Commerce (CIBC).

All five banks maintain their headquarters in Toronto on Bay Street.

Together, these banks constitute more than 85% of the Canadian banking industry.

A wide range of investors hold shares of each bank; by law, each entity or individual can own a maximum of 20% of the outstanding stock.

The Big Five also rank among the top 100 banks in the world.

Below is an overview of the Big Five banks by asset size and net revenue (as of October 31, 2023).
