Toronto Maple Leafs right-winger Mitch Marner will look to build off a stellar rookie campaign, as he is set to join Team Canada at the IIHF World Championship, according to Terry Koshan of the Toronto Sun.

If it weren't for one of the best rookie classes in NHL history, Marner would have gained some consideration for the Calder Trophy, as he finished the season with 19 goals and 61 points. The 19-year-old will be joining a Canadian team with a plethora of talent up front.

Defenseman Morgan Rielly will not be joining his Maple Leafs teammate overseas. Rielly won gold with Team Canada at last year's World Championship, played with Team North America at the World Cup of Hockey, and is coming off his first NHL playoff run. That's a lot of hockey in a calendar year.

"I feel like it's best for me to go home and get some rest, recharge," Rielly told Koshan.

The tournament is set to begin May 5 and will be played in both France and Germany.
