The Winnipeg Free Press‘ Lindor Reynolds reported that 72-year-old Susan Griffiths made the decision to travel to Europe for legal assisted suicide after being diagnosed with multiple system atrophy, which includes a loss of bodily functions and severe pain.

Griffiths passed away on Thursday at a Switzerland clinic after drinking a poisonous mixture of water and pentobarbital.

“I have to go to Switzerland because there’s no such service in Canada for Canadians who are drastically ill and want not to live anymore,” Griffiths told the Free Press earlier this month. “But it’s what I want because I do not want to live in the conditions that I have now.”

In a letter to Parliament before she died, she urged lawmakers to legalize assisted suicide.
