Jani Nyman tied it for Finland late in regulation and scored the deciding goal in the shootout.

“I don’t know what happened, but we weren’t ready at the start,” Swedish forward Noah Ostlund said. “We don’t make to make excuses. We have to be better next time."

Boston University star Macklin Celebrini scored twice for Canada.

“One of those games where you just got to keep going,” said the 17-year-old Celebrini, expected to be the top pick in the NHL draft. “We just had to push through ... it’s never going to be perfect.”
