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.
CANADA 4 GERMANY 1
Canada came back strong after Saturday's 6-0 loss to Russia, defeating Germany 4-1 on Monday to improve to 2-1 at the tournament.
Nolan Foote, Liam Foudy, Calen Addison and Ty Dellandrea scored Canada's goals, while Oilers forward prospect Raphael Lavoie played 15:39 in the win.
With Alexis Lafreniere (injury) and Joe Veleno (suspension) unavailable up front, Lavoie saw his presence elevated and was also slotted in on Canada's top power-play unit. He provided the screen in front of German goalie Hendrik Hane when Addison blasted home his goal.
Oilers goalie prospect Olivier Rodrigue did not dress, while Joel Hofer made 18 saves for the win and Nicolas Daws was the back-up.
Canada concludes preliminary round play on Tuesday against host nation Czech Republic at 11am MT.
SWEDEN 6 KAZAKHSTAN 2
Sweden secured its third straight win at the tournament and 51st in a row during World Juniors preliminary round action as they expectedly dominated Kazakhstan to the tune of a 6-2 decision.
Samuel Fagemo continued his high-scoring tournament with his fourth and fifth goals to help the Swedes move back into first place in Group A, while Oilers blueline prospect Philip Broberg played 16:08 with two shots on goal.
Sweden will look to extend its amazing preliminary round win streak to 52 games on Tuesday when they conclude round-robin play against Slovakia at 7am MT.
UNITED STATES 4 CZECH REPUBLIC 3 (OT)
Oilers forward prospect Matej Blumel and the host Czechs lost a heartbreaker to the Americans on Monday, 4-3 in overtime as Group B continues to be tightly-contested.
After USA jumped out to a 1-0 lead, Czech captain Libor Zabransky tallied twice to give the host nation a 2-1 lead through 20 minutes.
The Americans scored twice in the middle frame to regain their lead, but the Czechs netted the 3-3 equalizer from Petr Cajka midway through the third, shortly after they had another would-be tying goal disallowed.
Cole Caufield capped off the back-and-forth affair with the sudden-death winner that vaulted USA into first place in Group B with eight points, while the Czechs are in third with four points.
Blumel played 17:27 and recorded two shots on goal for the Czechs, who can still finish second in the group with a regulation win over Canada in their final-round robin match on Tuesday at 11am MT.
With that result, combined with the result of Tuesday's other Group B game between Germany and Russia, the host nation could also finish third, fourth or fifth in the pool.
