Trizec was created as a holding company of Montreal-based Webb & Knapp (Canada), in July 1961. It was a Toronto-based amalgamation of three ("tri") concerns; "z" (William Zeckendorf of Webb & Knapp), "e" (Eagle Star Insurance of London, England), and "c" (Covent Garden Properties, also of London). By 1968, Trizec was Canada's largest shopping center owner-operator, with holdings such as Burnaby, British Columbia's BRENTWOOD CENTRE (1961), Nova Scotia's HALIFAX CENTRE (1961), Montreal's PLACE VILLE MARIE ["plahs veel muh-ree"] (1962) and Toronto's YORKDALE CENTRE (1964).
