Construction of the mall was announced on February 27, 1969, by Steinberg's and Eaton's. The consortium announced that a 150-store mall would be built on a property next to the Laurentian Expressway, subject to the construction of the necessary infrastructure by the newly formed city of Laval. The project had been delayed after a zoning bylaw proposed by mayor Jacques Tétreault that would effectively have given the Carrefour Laval consortium a monopoly over the development of the proposed downtown core of Laval was challenged by the opposition and by members of his own party, who supported the construction of a second mall in the immediate vicinity by the Oshawa Group. A zoning amendment proposed by opposition councillor Lucien Paiement, which allowed the Oshawa Group to build its own mall was adopted. By then, Morgan's and Simpson's had joined the Carrefour Laval consortium. However, Morgan's dropped out, preferring instead to anchor an expansion of the existing Centre Laval, just away on the other side of Expressway 15.

1983: The mall double its number of tenants by expanding to the west with 125 new stores and a Sears department store.
1984: The Beaucoup concept is abandoned. Steinberg's and Miracle Mart now have their separate anchor spaces, although they remain side by side.
1993: Bureau en Gros becomes a tenant of Carrefour Laval. Moreover, work begins to convert the space that had been occupied by Steinberg's and M to accommodate what would have been the first Costco store in Canada, but this is halted when Costco and Price Club merge the same year, since there was already a Price Club store right across the expressway.
1994: Rona L'Entrepôt opens up its first store ever on what used to be the anchor spaces of Steinberg's and M.
1995: Wise closes.
1996: Les Ailes de la Mode opens in the spaces of the old Pascal's and Wise stores.
