The Oilers have four prospects competing at this year's IIHF World Junior Championship in Ostrava and Trinec, Czech Republic.
Eighth-overall pick from the 2019 NHL Draft, defenceman Philip Broberg, is suiting up for Sweden.
Also from the 2019 Draft, 38th-overall pick Raphael Lavoie is playing forward for Canada, joined by goaltender Olivier Rodrigue, who was selected 62nd overall in 2018.
The host Czechs feature forward Matej Blumel, whom the Oilers picked 100th overall at the 2019 Draft.
SWEDEN 6 SLOVAKIA 2
Philip Broberg buried Sweden's third goal of the game en route to a 6-2 victory over Slovakia that cemented their spot as the top team in Group A.
With just under seven minutes to go in the opening frame and Sweden already up 2-0, Broberg corraled a pass from Linus Nassen in the high slot and fired a quick wrist shot past Slovak goalie Samuel Hlavaj for a shorthanded marker.
Edmonton's 2019 first-rounder finished the game with a goal on three shots and a +2 rating in 15:18 TOI as his Swedes steamrolled through round-robin play yet again with 52 consecutive wins at the tournament.
The medal round hasn't been quite as kind for Tre Kronor as their most recent gold medal came in 2012, though they do have five second-place finishes and one bronze medal since 2008.
Sweden will start its quest for the top prize in the quarterfinal round on Thursday when they face the host Czechs.
CANADA 7 CZECH REPUBLIC 2
Just a few hours after Sweden secured top spot in Group A, Canada did the same in Group B with a decisive 7-2 victory over Czech Republic to conclude the preliminary round.
Despite the lopsided final score, the game did get as close as 4-2 in the second period when the Czechs scored their only goals just 14 seconds apart. Unfortunately for the host nation, Canada made it 5-2 just 10 seconds later as the teams set a new tournament record for the fastest three goals scored by opponents.
Both Oilers prospects were held off the scoresheet, as Raphael Lavoie played 12:58 for Canada and registered one shot, while Matej Blumel logged 19:44 for the Czechs with one shot as well.
Canada will play Slovakia in Thursday's quarterfinal round, while Czech Republic will take on Sweden.
