Opened in November 1971, the mall has expanded several times and today includes approximately 100 stores and services, and encompasses 570,837 square feet (53,032.5 m2) of retail floor space.

The larger, 2 level Sunridge Mall as well as a Real Canadian Superstore outlet is one C-Train stop to the north, about 2000 metres away, itself in a very large commercial setting with several blocks of stores concentrated together.
