Jonathan Drouin and Sam Reinhart both had a goal and an assist, while Aaron Ekblad and Charles Hudon also found the back of the net for Canada, who erased four one-goal deficits in the game, including three in the third period alone.
Canada found themselves trailing 1-0, 2-1, 3-2 and 4-3 before Hudon sent the game to overtime with 6:59 left in a wild third period.
After the five-minute overtime solved nothing, the teams went to a shootout where Drouin was the lone Canadian goal scorer, while the Czech’s were able to beat goaltender Jake Paterson twice.
Canada, who returns to action on Monday morning (8:30am PST) when they take on Slovakia (1-0-0-1), picked up one point in the loss, but now trails the United States by two points for top spot in Group A.
Canucks prospect Bo Horvat found the score sheet for the second straight game as the London Knights star took a feed from Connor McDavid at the side of the net and one-timed it to a wide open Reinhart in the slot to put Canada on the board with 4:10 remaining in the first period.Bo Notes
-Horvat once again centred a line with Connor McDavid and Sam Reinhart. The trio also served as the second power play unit with defenseman Mathew Dumba and Josh Morrissey on the point.
-Horvat and Reinhart played as a pair on the penalty-kill.
-The 6-foot, 205-pounder went 7-for-14 (50%) in the faceoff circle, which drops him to 60% (18-for-30) overall in the tournament.
-The Rodney, Ontario product failed to pick up a shot on goal and finished minus-1, which puts him at plus-1 through two games.
-With 8:00 remaining in the first period, Horvat set up Reinhart in the slot but the Kootenay Ice captain rang the puck off the crossbar.
-Late in the second period, Horvat blocked a shot off his foot and appeared to be in pain, but managed to stay out and finish his shift.
