Trizec was created as a holding company of Montreal-based Webb & Knapp (Canada), Limited in July 1961. It was a Toronto-based amalgamation of three ("tri") concerns; "z" (William Zeckendorf of Webb and Knapp), "e" (Eagle Star Insurance of London, England), and "c" (Covent Garden Properties, Limited, 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).
