The contestants have a rather rude awakening on their return home to Canada - because they are dropped into the rushing waters of the Great Lakes, just meters from the destructive wonder of Niagara Falls! After a daring escape, they are startled to find that Chris is now dissolving the teams. He decides to take the opportunity to pair them up for what may be the most emotionally challenging competition yet, and teams of one boy and one girl must compete in races based on Niagara Falls' historical place as the 'Honeymoon Capital of the World'. After a blindfolded trust challenge leads each bride to a wedding gown, the couples must walk a tiny tightrope over the falls and get through 'U.S. Customs' (AKA Chef, in a little booth and a particularly foul mood.)
