World Mitochondrial Disease Week (WMDW) 2025 

From September 15th to the 21st, 2025, the global mitochondrial disease community unites to raise awareness for those living with mitochondrial disease.

We have a number of activities planned to support the Canadian mitochondrial community and contribute to international awareness efforts. Take a look below!

Throughout September, and especially during World Mitochondrial Disease Week (September 15–21, 2025), Canadians from coast to coast come together to use their energy to participate in Walk N’ Roll 4 Mito. This year marks the 10th anniversary of the event, which began in 2015 thanks to MitoChampion Louise Gibson in Mississauga, Ontario. Since then, it has grown into a powerful, nationwide movement. Be part of this milestone and help us celebrate a decade of community, determination, and energy!

On September 20th, 2025, landmarks around the world will light up in bright green to celebrate WMDW and raise awareness for those living with mito.
