The MS Walk is a day of celebrating community and bringing together those who are directly and indirectly affected by Multiple Sclerosis. Multiple Sclerosis or MS is a nervous system autoimmune disease that affects over 90,000 Canadians. 12 Canadians a day get diagnosed with MS and enter a life of uncertainty with the disease ranging in symptoms and progression. MS Canada provides support to those affected by MS and their families with a wide range of services, programs, mobility aid grants as well and fundraise money to support research to help end MS.
