Connor McDavid scored at 8:18 of overtime in the 4 Nations Face-Off championship game to give Canada a 3-2 victory over the United States on Thursday night as the North American rivals turned what had been a tune-up for the 2026 Olympics into an geopolitical brawl over anthems and annexation as much as international hockey supremacy.

American fans lightly booed the Canadian national anthem and roared out their own Thursday night before the championship game of the 4 Nations Face-Off, a matchup between the United States and Canada that has taken on collateral importance in the wake of cross-border political animosity.

The 4 Nations Face-Off has already delivered an instant classic international hockey game with the fight-filled preliminary round matchup between the United States and Canada last week in Montreal.
