[1] The development of King Square began as an initiative to cater to the growing Asian demographic in the region, particularly in Markham and the adjacent Richmond Hill.

The site was initially acquired by King Square Ltd. in partnership with Fortress Real Developments around 2010, with construction officially starting in 2013.

Although the mall was initially envisioned to span nearly 1,000,000 square feet and house over 1,000 retail units,[2] various factors led to a scaled-back project that ultimately resulted in its current size.

King Square Mall features a architectural style that reflects Asian cultural themes, designed to resemble a vibrant lifestyle destination.

Additionally, plans for further development on adjacent properties were anticipated, with proposals for a hotel and residential spaces aimed at enhancing the area's community structure.
