Currently we can estimate that the number of Canadians living with MS is 90,000. That might be an underestimate, given that there are likely to be individuals in the country who don't get diagnosed. It's often a fairly complicated path to getting diagnosed. As we know, for many people, it takes years.
We also have come to understand that there is a prodrome, or a pre-clinical state and we can see individuals with a distinct health utilization pattern as many as five to 10 years out before the state of diagnosis.
