An uninhabited island at the centre of a century-old Canada–US territorial dispute is back in the spotlight after a Canadian senator urged Ottawa to assert sovereignty over the piece of land.
Senator Jim Quinn from New Brunswick has taken issue with an American boat tour group that describes Machias Seal Island on its website as being "on the Maine Coast".
He has called on Ottawa to review its permitting of the tour group to visit the island - home to thousands of puffins - as well as the mention of the group on a government website.
Machias Seal Island is a tiny, rugged island located in a disputed "Grey Zone" between the US state of Maine and the Canadian province of New Brunswick.
The tear-drop shaped island is a migratory bird sanctuary and is described as "one of the most important seabird nesting colonies" by the Canadian government. It is also home to one of the most southerly colonies of the Atlantic puffin.
