On Wednesday June 6, 2017 the Permanent Representative of Canada to the International Atomic Energy Agency (IAEA), Ambassador Mark Bailey, delivered the instrument of ratification to IAEA Director General Yukiya Amano at a ceremony at IAEA Headquarters in Vienna, Austria. Canada’s ratification follows the entry-into-force on January 1, 2017 of the Nuclear Liability and Compensation Act, domestic legislation that strengthened Canada’s nuclear liability regime and permitted Canada to ratify the Convention on Supplementary Compensation for Nuclear Damage. The United States, Canada’s closest neighbour, ratified the Convention in 2008. The implications are significant for Canada as Article XIII provides that with few exceptions, jurisdiction over actions concerning nuclear damage from a nuclear incident lie only with the courts of the Contracting Party within which the nuclear incident occurs. For foreign suppliers and contractors with assets for example, in the United States who are working on refurbishments of the Darlington or Bruce Nuclear Generating Stations in Canada, they are no longer exposed to lawsuits in the U.S. arising from a nuclear incident at either of these sites in relation to work they are doing in Canada.
