Before the competition gets underway in the Thousand Islands ON, teams react to surprising coaching changes. Players compete in three challenges in, on, and over the water, and a second team goes home.

In the semi-finals, solo Players do the Smokestack Climb in Sudbury; the teams go 750m underground in Mine Rescue; and pairs complete in a Sea-Doo Slalom tubing course. Only two teams make the cut.
