Designer Superstar Challenge

Designer Superstar Challenge also known simply as Superstar Challenge is a show hosted by Karen Bertelsen on HGTV Canada that has had four seasons. Similar to the American series HGTV Design Star, the show features aspiring interior designers competing in a series of challenges, following which one contestant is named the "design superstar" at the end of the competition.

It is the original "Superstar" themed show on HGTV, and went on to inspire Handyman Superstar Challenge, Superstar Chef Challenge, and Superstar Hair Challenge.
