[3] Place Rosemère began modestly when it first opened in August 1975 with approximately 65 stores at 337,000 square feet anchored by Woolco, Beaver Lumber and Dominion.

[4] The Hudson's Bay Company had planned a La Baie store for the ianguration of the mall,[4] but nothing ever came out of this announcement and it's only on March 13, 1991, that it opened at Place Rosemère.

[9][8] The mall itself reached 605,677 square feet and almost doubled its floor area.

Another expansion, opened on September 19, 2002, brought the mall to its current size and layout as Wal-Mart relocated to a new location earlier in February 2002 and a new Sears store moved to the old Wal-Mart store.

[9] This expansion coincided with the closing of two other anchor stores when Canadian Tire moved to a standalone location across the street and Provigo, one of the last supermarkets to be located in a Canadian regional mall, closed its doors.
