The TSA organizes and hosts an annual poster competition exploring a theme relating to architecture and design. The aim of the competition is to raise awareness and to celebrate design. It is open to everyone and is widely promoted through the TSA, regional allied design groups and national to international organizations. The jury is comprised of design professionals from various disciplines and includes a representative with in-depth knowledge of the theme.
 
The competition is launched in Spring with winners announced in May at the Toronto the Good Party. Cash prizes are awarded to those entries selected for first, second, and third place. Competition finalists are included in an exhibit which travels to various venues throughout the city as well as being featured on the TSA website.
