Following major expansion, the mall marked its reopening in August 2009, including a new food court and added parking. These expansions included forty new stores under a new two-level parking deck and a station on the expansion of the LRT system, whose opening ceremony was April 24, 2010.
On August 12, 2010, Southgate celebrated the 40th anniversary of its opening, When the centre opened with Woodwards, Woodwards Food Floor and The Bay it was at the time the largest shopping centre west of Toronto and the first centre built in Alberta that housed two anchor department stores. In 1993, Woodward's went bankrupt; its space was converted to Eaton's, which left Heritage Mall. In addition, Safeway occupied the food floor of the former Woodward's. By 1999, Eaton's went bankrupt and its space became a Sears the following year, also relocating from the nearby Heritage Mall, which was subsequently decommissioned, demolished, and converted into a mixed-use development called Century Park.
