Belgium saw off a determined Canada by the skin of their teeth to edge an opening World Cup victory.
Canada - playing in their first World Cup finals match for 36 years - flew out of the box against a creaking Belgian back line, and saw Alphonso Davies' penalty saved by Thibaut Courtois after 10 minutes.
The Canadians kept coming, but with a lack of quality letting them down in attack, they were punished when Michy Batshuayi latched on to Toby Alderweireld's ball to score shortly before half-time.
