Evason first played for Canada at the 1984 World Junior Ice Hockey Championships while in the midst of a terrific campaign for the Kamloops Junior Oilers. His selection to the squad was somewhat of a surprise, but he proved to be a productive player, recording six goals and nine points in seven games for the fourth-place Canadian squad. The Canadians narrowly missed out on a medal to the third-place Czechoslovakian team, losing 6-4 in their match against them that decided the medals. It would be thirteen additional years before Evason was again selected to represent his country.
