Canada got off to an early 2-0 lead, then the United States fought right back to tie it up at 2-2. Canada then got out to another two-goal lead, but the United States fought back yet again to tie it up at 4-4 and that's the way it stayed until the shootout.
The U.S. and Canada traded shots until the fourth round where Troy Terry scored to give the United States the lead and one final save from U.S. goaltender Tyler Parsons sealed a thrilling 5-4 victory for the Americans.
Tanner Laczynski, the Flyers' sixth round pick at 169th this past summer, was back in the lineup for the gold medal game and appeared in 8:17 of ice time to help the U.S. claim their first World Junior title since 2013.
Laczynski joins Sam Morin (Canada - 2015) and Shayne Gostisbehere (USA - 2013) as the most recent gold medal winners in the World Junior Championship. He finished the tournament with two points (1g-1a) in seven games.
Overall, the 2017 IIHF World Junior Championships were a success for Flyers prospects, who picked up five medals in total, as the franchise boasted a record nine participants - all of which made the tournament round. It was also the most prospects than any other NHL team had in the tournament.
For Canada, goaltender Carter Hart and defenseman Philippe Myers walk away with silver medals, while Russia earned a 2-1 overtime win over Sweden, giving prospects Mikhail Vorobyov and German Rubtsov bronze medals.
Starting goaltender for the Canadians in the gold medal game, Hart stopped 31 shots, including all seven in overtime and four of five players in the shootout in the loss. He ends his first World Junior tournament with a 3-0-1 record and a 2.38 goals-against average and .906 save percentage. Hart is the Flyers' second round pick in 2016 at 48th overall.
Canada was without one of their top defenseman in the tournament, Flyers prospect Philippe Myers, who suffered an injury in the final game of the round robin and did not appear in the medal rounds, missing all three games. Myers recorded three assists in his four games and logged close to 19 minutes of ice time per-game before going down with injury.
For the Russians, Vorobyov appeared throughout the tournament on the top line and recorded points in six of the total seven games played. He finished with 10 assists, which led all players in the tournament and tied for third in overall scoring.

Vorobyov was selected by the Flyers in the fourth round (104th overall) in 2015.
German Rubtosov saw limited ice time in his first World Junior tournament. The Flyers first round pick in 2016 at 22nd overall was one of just four 18-year-olds to even make the Russian squad. He appeared in five games but did not play the last two contests due to injury.
