Collaboration and research imperatives for a growing right-to-die movement.

This commentary discusses key controversies surrounding assisted dying that have now evolved, creating further tensions and divisions among assisted dying organizations, adding to existing controversy based on ethical, political, and theological grounds-all shaping public health policy in Canada and elsewhere. The growing worldwide trend in the right-to-die movement is increasingly focusing on medical assistance in dying (MAID) with most service organizations (societies) devoted to a sanctioned, legislatively prescribed approach. While in consequence important changes have occurred in numerous countries and jurisdictions with successful challenges on the absolute prohibition to assisted dying, it is arguably the case that as many-if not more-people are still denied this controversial right to have a peaceful, reliable, and painless end of their own choosing.
