​​

Ten of the country's most passionate and opinionated experimenters and problem-solvers are put to the test in a series of diverse and head-scratching challenges to find out who is the brightest of the bunch. In a supersized arena of grit and wit, contestants compete with and against each other in challenges that test their knowledge, problem-solving skills, leadership, cooperation and strategy. The player with the fewest points after each final elimination challenge is sent home. Each of these self-proclaimed know-it-alls is on a quest to earn the title of Canada's Greatest Know-It-All.
