Aubry was one of the physicians consulted for the 2011 report "Brain Injury Guide for Youth", 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. Aubry has also spoken against focusing too much on one sport at a young age, as it has not only "taken the fun out of it", but also has physical and cultural risks in not developing the person. At the 2010 World Hockey Summit, Aubry called for raising the minimum age for body checking to 13 or 14 and eliminating hits from behind altogether. Based on his research and experience, he argued that children should be developing skills instead, as they are the most vulnerable to injury due to height and weight differences; he cited research which highlights risks of long-term effects for athletes who have had multiple concussions, specifically younger hockey players. Aubry called for instructing players that a body check is a way of separating an opponent from the puck, rather than continuing the perception of hockey as a rough sport where putting an opposing player through the boards is considered part of the game, given that no safety equipment could prevent serious injuries such as the Ronny Keller incident resulting in paraplegia. Aubry has also testified before the Canadian International Trade Tribunal as an expert witness on the safety of hockey equipment. 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. He was one of the authors in the 2017 report "Can visible signs predict concussion diagnosis in the National Hockey League?" He assessed Senators' player Clarke MacArthur for post-concussion syndrome, and said that given MacArthur's history, it would be too risky to return to play. He also cited research that in-game concussion protocols need to be strictly adhered to, and reiterated the need to evaluate players at the first sign of possible concussion, rather than staying in the game. He recommends a proactive approach to ensure players do not return to play too soon, citing recent studies on the numbers of concussions in minor ice hockey, and specifically at the peewee age level when players are typically exposed to body checking for the first time. 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.
