August 1959 brought the completion of the first shopping mall in Manitoba. POLO PARK CENTRE, an open-air structure, was located in the western environs of Winnipeg, then the nation's third-largest city. This complex featured Simpsons Sears, S.S. Kresge, Zellers and Loblaws and Dominion supermarkets.

Meanwhile, shopping centre development had continued, unabated, in the Alberta province. An open strip plaza, Edmonton's SHOPPERS' PARK-WESTMOUNT, had opened in August 1955. Its original stores included Simpsons Sears, Zellers, S.S. Kresge, F.W. Woolworth and Loblaws and Dominion supermarkets.
