International career
Youth
Bustos has represented Canada at youth level and was a part of the Canadian team at the 2013 FIFA U-17 World Cup. He courted controversy in July 2014 when he accepted a call-up from the Chile U-20 squad for a training camp prior to an invitational tournament in the United States. This prompted a negative reaction from Canadian soccer media circles. Bustos would state in an interview that he was not spurning Canada, and simply "keeping his options open." He was cut from the final Chile squad, however. Bustos was subsequently left off the Canadian U-20 team that went to 2014 Milk Cup the following month, but returned to the team for a series of friendlies in November, where he scored a goal for Canada against Russia's U-21 side. In January 2015 Bustos made the Canadian team for the 2015 CONCACAF U-20 Championship.
Senior
Bustos received his first call up to the Canadian senior team for a friendly against Ghana on October 2, 2015. Bustos made his debut for the senior side on October 13 as a substitute, replacing fellow debutante Charlie Trafford.
Personal life
Marco Bustos has a Chilean father and an Italian mother.
