On April 23, 2018, Canada's Deputy High Commissioner to the UK, Sarah Fountain Smith, deposited Canada's instrument of ratification to the 2010 Protocol to the International Convention on Liability and Compensation for Damage in Connection with the Carriage of Hazardous and Noxious Substances by Sea, 1996 (2010 HNS Convention). The treaty has now been ratified by three States, Canada, Norway and Turkey. The total quantity of contributing cargo has reached 28.7 million tonnes, or nearly 72% of that required for entry into force. The 2010 HNS Convention aims to deliver the uniform and comprehensive regime needed to provide compensation for costs, including clean-up and restoring the environment, in the event of an incident involving HNS cargoes. The treaty complements existing regimes already in force for the transport of oil as cargo, bunker oil used for the operation and propulsion of ships, the removal of hazardous wrecks and claims for death of or personal injury to passengers, or for damage to their luggage, on ships. HNS covered by the Convention include: oils; other liquid substances defined as noxious or dangerous; liquefied gases; liquid substances with a flashpoint not exceeding 60˚C; dangerous, hazardous and harmful materials and substances carried in packaged form or in containers; and solid bulk materials defined as possessing chemical hazards.
