Seguin opened the scoring just 50 seconds into the game with his fifth goal of the season. Reto Berra failed to handle a Jake Muzzin shot cleanly and Seguin shovelled the loose puck into the net.
Switzerland drew level on a soft goal at the 6:21 mark. Trachsler put the puck on net from the boards at the goal-line, and the puck went pack fooled Canada goaltender Mike Smith and in the net.
McKinnon put Canada up 2-1 with 17 seconds left in the second period. McKinnon charged in on the left wing and fired a shot past his Colorado Avalanche teammate.
Ekblad extended Canada's lead to 3-1 when Couturier forced a deep turnover in the Swiss zone and found the young Florida Panthers defenceman in front of the Swiss goal.
Canada essentially put the game away with two goals in the final minute of the second. Eberle made it 4-1 with a power-play goal, putting in the rebound of a Sidney Crosby shot. Crosby's assist gave him at least a point in every game so far at the tournament.
Eakin extended Canada's lead to four goals when he out a rebound past Berra with less than a second to go before the second intermission.
Brunner gave Switzerland temporary life when he took control of a turnover caused by a Canadian defensive breakdown and poked the puck under Smith.
But that was as close as the Swiss would come as Couturier tapped in the rebound of a Tyler Toffoli shot to make it 6-2, and Giroux capped the scoring with a power-play goal.
Switzerland had a goal disallowed early in the first period following a lengthy review.
