No, you can’t visit the Edmund Fitzgerald shipwreck by diving or operating submersibles without a license. The Ontario Heritage Act has allowed the Ontario government to charge heavy fines for diving and operating side scan sonars, underwater cameras, and other submersibles without a license since April 2005. The wreck is entirely located within the territorial waters of the Canadian province of Ontario, and diving on the wreck has been completely banned by the Canadian government by all means including ROVs and manned submersibles.
