Haida and Buffalo's museum ships under Great Lakes restrictions

Does Haida's presence in the Great Lakes violate the restrictions on warships there?

The suggested explanation combines museum status with reciprocal acceptance of Canadian and American historic ships.

Haida in Hamilton and the museum ships in Buffalo raise a question about restrictions on warships in the Great Lakes. Museum status is offered as part of the explanation, although the agreement is said not to have explicitly anticipated that category. Another explanation is reciprocal tolerance: both countries have historic vessels present and accept the other's arrangement. These are suggested explanations for how the museum ships were accommodated; the suggestion that Haida's presence is a war crime is a joke.
