He researches and lectures on concussions, plays a leadership role for safety in sport, and is an injury prevention activist in minor ice hockey.
[1][8] Aubry was one of the physicians consulted for the 2011 report Brain Injury Guide for Youth,[13] and was one of the medical experts that helped write the module Making Head Way in Sport released in 2014, for the Coaching Association of Canada to educate on when it is okay to return to play.
[21] Aubry stated that awareness on the long-term effects of concussions increased partially because of the injuries to Sidney Crosby, but noted that physicians in the National Hockey League still disagree on when players are healthy enough to return to play.
[18] He also spoke at the Canadian Academy of Sport and Exercise Medicine (CASEM) conference in August 2018, to address post-concussion syndrome, and methods for diagnosis.
[1][8] In this role, he advised against international travel to Beijing for the 2003 Women's Ice Hockey World Championships, which was ultimately cancelled because of the SARS outbreak.
[30] In ice hockey at the 2002 Winter Olympics, Aubry stated that the drug which Mattias Ohlund tested positive for was contained in the medicine given to him after eye surgery, and should not be considered a doping infraction.
[31] In ice hockey at the 2014 Winter Olympics, Aubry stated that Nicklas Backstrom's positive test for pseudoephedrine was a result of Zyrtec-D taken to treat sinusitis, and it should not be considered a doping infraction.
[32][33] Since Aubry became CMO, IIHF competitions and the Winter Olympic Games, ice hockey officials have been instructed to penalize all hits to the head, and are critiqued for any such missed calls.
[27] "The fight in reducing concussions is global in nature and needs the help of every participant in the sport to prevent this injury through fair play, enforcement of the rules and other measures."
[1][8] He pushed for Hockey Canada to adopt zero tolerance rules for hits to the head, whether accidental or not, and recommended that teams have seminars on the risks of concussions.
