August 13, 2018 — Canadians often boast that their 5,525-mile boundary with the United States is the longest undefended border in the world. But tempers have frayed on at least one small stretch.
Machias Seal Island is a 20-acre, treeless island teeming with puffins, razorbills, terns, eiders and other seabirds, making it a prime destination for birdwatchers. Canada and the United States both claim sovereignty over the island, which is about 10 miles off the coast of Maine, and the surrounding 277-square-mile Gray Zone, where fishermen from both countries compete over valuable lobster grounds.
In late June and early July, Canadian fishermen said, U.S. Border Patrol agents in speedboats intercepted Canadian lobster boats in the Gray Zone.
“I have no idea where they came from,” said Laurence Cook, a lobsterman and representative of the Fishermen’s Association from nearby Grand Manan Island. “We’ve never seen U.S. Border Patrol in the Gray Zone before.”
