This is the third report of the Public Health Agency of Canada's (PHAC) Injury in Review series, providing important national surveillance statistics on the causes of traumatic brain injuries (TBI) across the life course, including sports, seniors' falls, assaults, consumer products, and more. The breadth of topics covered in this report helps to tell the story of how TBI, including concussions, are affecting Canadians of all ages. Knowing how these injuries occur is critical to understanding the impact of TBI on Canadians.
