Bonjour. Yes, there are multiple examples and multiple ways of doing it. Some countries have archeological laws that protect at large, as these regulations would. France is one example. Australia is another. In Europe, 45 countries signed the Valletta Convention, which basically covers archeological sites on land and underwater.
Other countries have taken a different route and have specifically targeted military wrecks in addition to heritage wrecks. The U.K. is probably the prime example, and the United States also has specific regulations for military wrecks. In those cases, they cover not only shipwrecks that sank at a time of war, but also anything that can conserve and cover wrecks and human remains. It's not specifically war graves, but military wrecks. The U.S. covers not only American wrecks, but also protects other countries' wrecks in their waters. You have a vast array of possibilities.
The regulations under this one act, I think, would help us with the fact that we have to deal most of the time with the jurisdiction of the provinces, who have archeological legislation for the seabed. The Canada Shipping Act, for example, is more addressed at wrecks in the water column. The regulations would allow us to have a common approach, and one-to-one agreements with the provinces to manage the permits, for example.
