WHAT'S Spinal muscular atrophy (SMA)?
Spinal muscular atrophy (SMA) is a serious rare genetic disease that affects about 1 in every 6,000 babies. It causes muscles to weaken over time — making it harder for people to move, breathe, and even swallow.
While there’s no cure, early and ongoing treatment can change lives. It can slow the disease, preserve muscle strength, and help people with SMA live longer, fuller lives.
Canada is the only G7 country where all SMA patients don’t have access to life-saving treatments.
There are approved treatments available in Canada that have the potential to slow down or even reverse the progression of SMA. But as of 2025, only Quebec and Saskatchewan provide full coverage of these treatments for people over 25 years old. As a result, adults with SMA in other provinces and territories are left without treatment as their condition worsens along with their mobility and independence.
