So it turns out there is another design show called Designer Superstar Challenge for Canada's HGTV. Unfortunately they don't have the episodes online and I can't find anything posted about the show. If any of our Canadian readers can post it on YouTube, I am sure there are some of us that would like to check it out.
Would be curious to see how this compares to Top Design?
(Thanks for mentioning the show Terramia, was actually going to post this a few days ago!)
