Canadian federal legislation setting out the framework for medical assistance in dying (MAiD) in Canada came into effect in June 2016. Because of section 86(1) of the Corrections and Conditional Release Act, as soon as MAiD became available in the community, it also needed to be made available to federal prisoners. There are some good reasons to be concerned about MAiD in the Canadian corrections system based on logistical, legal, and moral considerations. Fortunately, Canada is not the first country to decriminalize assisted dying and so Canadian policies and practices can be compared to others and take some lessons from their experiences.
