It has been a few years ago, but a friend who is "Native American" and who held a salmon license was required to obtain appropriate "identification papers" for doing business in and with Canada, and that is the exact language that Canada used in the entry for "nationality" on the papers he received.
News reports subsequent to that time indicated that Canada was considering a change in that terminology, and they may have done so; but I haven't heard whether a change was made official.
Most of the northwest small fishing boats that fish for salmon do use "native rights" salmon permits via partnership with a qualified person or by purchase of the boat - and license - from one. There are other ways of getting a license, but the catch limits for a qualified "tribal/native license" are much more liberal. The license is issued to the boat, based on full or partial ownership by a qualified "native," and can/must be passed with sale of the boat.
Or so says my shaman friend.
But the point intended was only that "incursions" of the kind described are almost a routine thing in any coastal region.
