The intersection of Bay and King Street is often seen as the centre of Canadian banking and finance. Four of Canada's five major banks have office towers at the intersection — the Bank of Montreal at First Canadian Place, Scotiabank at Scotia Plaza, CIBC at Commerce Court, and Toronto-Dominion Bank at the Toronto-Dominion Centre — and the fifth, the Royal Bank at Royal Bank Plaza, is one block south. Historically, Bay and King was known as the "MINT Corner" from Montreal, Imperial, Nova Scotia, and Toronto, but since 1962 the Imperial Bank has been part of CIBC and the Bank of Nova Scotia has rebranded itself, so this nickname is no longer widely used. The core cluster of towers has crept north with the addition of the 50-storey Bay Adelaide Centre and the Trump Tower Toronto.
