Canada has introduced a new assisted suicide law that will only apply to Canadians and residents, meaning Americans won't be able to travel to Canada to die.
Visitors will be excluded under the proposed law announced Thursday, precluding the prospect of suicide tourism. Canadian government officials said to take advantage of the law the person would have to be eligible for health services in Canada.
The bill provides a choice "for adults who are suffering intolerably and for whom death is reasonably foreseeable." It says the person must be mentally competent, 18 or older, have a serious and incurable disease, illness or disability and be in an advanced state of irreversible decline of capability.
Canada's Supreme Court last year struck down laws that bar doctors from helping someone die, but put the ruling on hold while the government came up with a new law. The proposed law still requires approval in Parliament, but is expected to pass as Prime Minister Justin Trudeau's Liberal government controls the majority of seats.
Assisted suicide is legal in Switzerland, Germany, Albania, Colombia, Japan and the U.S. states of Washington, Oregon, Vermont, New Mexico and Montana.
California lawmakers also passed legislation, expected to take effect in June, where proof of California residency is required. Anne Singer, a spokeswoman for Compassion & Choices, a nonprofit that promotes assisted suicide laws, said all U.S. states with "death with dignity" laws have residency requirements.
Oregon was the first U.S. state to make it legal for a doctor to prescribe a life-ending drug to a terminally ill patient of sound mind who makes the request. The state does not track how many terminally ill people move to the state to die. There is no minimum residency requirement, but a patient must prove residency to a doctor with documentation such as a rental agreement, a voter registration card or a driver's license.
Germany's law applies to Germans and foreigners alike. Switzerland's law is valid for everyone in Switzerland, and people who take part in assisted suicides are not required to be residents or citizens, according to Justice Ministry spokesman Bernardo Stadelmann.
The Netherlands, Belgium and Luxembourg allow doctors, under strict conditions, to euthanize patients whose medical conditions have been judged hopeless and who are in great pain.
Canada's Supreme Court declared last year that outlawing that option deprives dying people of their dignity and autonomy. It had been illegal in Canada to counsel, aid or abet a suicide, an offense carrying a maximum prison sentence of 14 years.
Quebec already passed legislation last year after the court's decision. And since the top court ruling, Canadian judges elsewhere have given individual patients permission for assisted deaths.
To get a doctor's help under the law, a written request is required, either from the patient or a designated person if the patient is incapable, and the request would need to be signed by two independent witnesses. Two independent physicians or authorized nurse practitioners would have to evaluate it and there would be a mandatory 15-day waiting period unless death or loss of capacity to consent was imminent.
Justice Minister Jody Wilson-Raybould said the law ensures that dying patients who are suffering unbearable pain have the choice of a peaceful death. Health Minister Jane Philpott, a doctor, said she's had the experience of hearing a stop and has witnessed some people die miserably.
"This will have a positive, significant impact on the lives of Canadians," Trudeau said. "It is important to respect the choices made by Canadians."
The court's decision was spurred by cases brought by the families of two British Columbia women, who have since died. The decision reversed a Canadian Supreme Court ruling in 1993. At the time, the justices were primarily concerned that vulnerable people could not be properly protected under physician-assisted suicide. But the top court said last year that doctors are capable of assessing the competence of patients to consent, and found there is no evidence that the elderly or people with disabilities are vulnerable to being talked into ending their lives.
It has been more than 20 years since the case of another patient with Lou Gehrig's disease, Sue Rodriguez, gripped Canada as she fought for the right to assisted suicide. She lost her appeal but took her own life with the help of an anonymous doctor in 1994, at the age of 44.
