Been catching up on Dragons den canada on youtube and CBC (currently on season 5). I like both series (DD Canada and Shark Tank) but when you try to compare them side by side, Shark tank just seems to dumb it down a bit more, but at least it's still watchable.
I noticed a contestant on DD Canada season 1 that was also on Shark Tank USA. He was trying to harness the power for the ocean and got turned down on both shows.
