The Commercial Bank of Manitoba was incorporated in 1884 and ceased operation in 1893.
The president during most of its operation was Duncan MacArthur, a businessman and politician in Manitoba.
It experienced financial difficulties during most of its years of operation and suspended payment in July, 1893 because of heavy withdrawals.
A prominent Canadian political figure, Alphonse Alfred Clément Larivière, was one of the directors.
During its brief history, it was a Canadian banknote issuer and the bills that still survive are collectors items.
