Canada's Greatest Know-It-All

Ten Know-It-Alls from across the country are confronted with super sized challenges (one blustery, one explosive, and one that should be child's play) - and each other.

With nine remaining, the competition gets intense, as the Know-It-Alls compete in teams - but not everyone plays well with others.

The remaining eight are faced with the big question for a know-it-all: do they listen to the advice of others, or simply listen to the one person they know is right...themselves?

Know-It-Alls thrive on tackling problems alone. Now, the remaining seven get the chance to do just that, in 3 new individual challenges featuring bombs, snakes and planes.

The competition is getting more... complicated. In this episode, competitors struggle to find their voices, among many.

The 5 remaining competitors compete alone again and are challenged to truly step up and deliver, in a day of sheer terror to see if they can use their Know-It-All skills to save the day.

The Final Fou Know-It-Alls are paired up in teams of two. Now it's 2 brains struggling to work together, while trying to be the only one left standing, in 3 challenges of firepower, speed and memory.

The claimant of 'Canada's Greatest Know-It-All" title must win two challenges. The first testing knowledge, memory, direction and logic, and the second, a confrontation with what is a Know-It-Alls worst nightmare.
