Sledding/tobogganing was among the most common sports and recreation-related activities with reported concussions or other TBIs for children aged 5 to 9 years (3rd most common after ice hockey and physical education class among boys, and 2nd after ice hockey among girls).
All-terrain vehicle (ATV) use was the leading cause of moderate to more severe TBIs (i.e., showed the lowest percentage of concussions among all TBIs) among almost all children and youth, with the exception of females aged 5 to 9 (for whom it was equestrian sport/horseback riding) and males ages 10 to 14 (for whom it was baseball) .
In 2013, Hockey Canada implemented a new rule to prohibit body checking in the peewee age group (11 and 12-year-olds) and younger. This change has resulted in a 70% reduction in the risk of concussion, or about 4,800 fewer concussions across Canada .
Children under five were the most likely demographic to experience a concussion, followed by women over the age of 65 .
The number of physician office or emergency room pediatric visits for concussion-related complaints has quadrupled in Ontario since 2010 .
