Canada's law legalizing physician-assisted suicide — which allows doctors to help terminally ill patients end their own lives — will only apply to people who live in Canada, according to the Associated Press. That means terminally ill Americans who live in one of the majority of American states that doesn't allow physician-assisted suicide won't be able to travel to Canada to end their lives.

When Canada's Supreme Court legalized assisted suicide for patients who have a "grievous and irremediable medical condition," it led to speculation that the country would become a destination for people from elsewhere looking for aid in dying comfortably.

That's what happened in Switzerland, one of four European countries with assisted suicide, even for patients who are not terminally ill. One study found that more than 600 people traveled to Switzerland between 2008 and 2012 in order to use the country's aid-in-dying laws.

By limiting aid in dying to Canadian residents, the Canadian laws, which are scheduled to be announced Thursday, make it much less likely that the country will get an influx of "suicide tourism." And the spread of aid-in-dying laws in the US means they might not need to. After California legalized physician-assisted suicide in October, one in six Americans now lives in a state where it's legal for doctors to help terminally ill patients end their own lives.

More details on Canada's law will be released later today, including whether it will apply to people suffering psychologically as well as physically, to children, and to people who are not terminally ill, as a parliamentary panel recommended in February.
