Why should they cry to High Heaven?

Because, while the Canadians have every right and authority to stipulate
who may step ashore on Canadian soil they have no right by treaty or
other law to control who may serve aboard an American flag vessel.

There are a couple of centuries of legal and military precedent to
support the right of American seaman to pursue their trade aboard
American flag vessels without interference from any foreign government.

If the USCG allows a seaman to hold a document and perform the duties of
a crewmember aboard an American flag vessel under the authority of that
document no foreign government has any right to amend that authority. We
have fought wars to defend the rights of American seamen to pursue their
trade.

Don't be in such a hurry to trash your own rights and our nation's
sovereignty.
