Bauer was against the use of professionals at the World Championships. His participation in the national team ended in 1969, when Canada was granted permission by the IIHF to use a limited number of professionals while hosting the 1970 Ice Hockey World Championships. On January 4, 1970, Canada withdrew from international play and hosting the World Championships due to disagreements with the IIHF and the International Olympic Committee over the use of professionals and eligibility of players for the Olympics. The national team was disbanded shortly thereafter.
