The mall opened in 1979 and has since undergone four expansions. In 1999, Willowbrook underwent a major renovation and expansion, including a new 22,000 sq. ft. wing, with anchor stores such as Sport Chek. New interior and exterior signage, including a new logo, accompanied the other changes. Today, Willowbrook Shopping Centre is a regional centre with over 640,000 sq. ft.
The mall can be accessed via the Fraser Highway as well as the Langley Bypass. Both of these roads are major east-west corridors of the Greater Vancouver area.
In addition, all buses in Langley pass by the mall at some point. These routes run from Langley City, southern Langley or Aldergrove to Surrey Central Station of the SkyTrain system. One Surrey route also services Willowbrook, but on a limited basis.
