No-one ever slides up a slippery slope. They only ever go down. Euthanasia invariably involves a descent that is not so much like skidding to the foot of a steep hill as falling from a cliff. In no country in the world has this been quite as dramatic as in Canada.

The nation permitted euthanasia in 2016 when death was “reasonably foreseeable” in terminally ill patients. That safeguard was scrapped four years later and euthanasia has since been extended to people with disabilities. Moves are afoot to extend euthanasia to those with mental illness and a parliamentary committee last year recommended that children should be able to request a lethal injection without the consent of their parents.
