MAiD is not available for people whose only condition is a mental illness [1]. I'm saying this not for you but for anyone who may read this, particularly non-Canadians. It's not about "despair".

Yes that is the official stance. I do not believe that is being followed on the ground and is in any case a temporary condition. In 2027 it will be officially available with only a mental health issue.
