Meghan Mahon was born with a genetic condition called achromatopsia which is a cone-rod retinal dystrophy condition. She has 10 percent vision and lives a full and independent life despite being legally blind. Her brother Travis has the same condition.
As a child she was very active and participated in many sports including hockey and curling. She said being in a small community (hometown is Timmins, Ont.) made it easier for everyone to know her condition. She started competing in athletics in high school and competed in the Ontario provincial championships which had events for the visually impaired.
Mahon transferred to W. Ross Macdonald School for the Blind in Brantford, Ont. in Grade 12, where she was introduced to goalball. She made her senior national team debut at the 2016 Paralympic Games.
