Canada’s assisted-death law is unconstitutional and exposing people with coexisting physical and mental illness to “heightened risks of premature death” facilitated by the state, according to a wrongful death claim filed by the family of a 52-year-old man who was euthanized in a Vancouver clinic while out on a day pass from a hospital psychiatric ward.

It is the latest case involving a family challenging the lawfulness of an assisted death provision in Canada. Among those named is Dr. Ellen Wiebe, one of Canada’s most prolific providers of medically assisted death who has administered life-ending drugs to more than 400 people.
