Jonathan David scored a hat-trick as co-hosts Canada claimed their first-ever World Cup win in style, with a 6-0 thrashing over nine-man Qatar.
But it came at a cost after Ismael Kone suffered a broken leg and had to be strechered off.
The Canadians started the home tournament with a 1-1 draw against Bosnia and Herzegovina but bouced back in the best possible way on Thursday.
They led 2-0 by the half-hour mark thanks to goals from Cyle Larin and Jonathan David.
Qatar had their first player sent off in the 33rd minute. Homam Ahmed tripped Tajon Buchanan and the referee initially awarded Canada a penalty.
After video review the decision was overturned, while Ahmed's yellow card was upgraded to a red.
