The 18-acre stronghold of Machias Seal Island sits between the Gulf of Maine and the Bay of Fundy, preserving its status as the final territorial disagreement between the U.S. and Canadian governments. Both seabirds and a historic lighthouse reside on this island, making it a symbol of a historical border dispute complicated by escalating Canadian American relations.
A Lighthouse, a Legacy, and Two Brothers
The lighthouse keepers, Russell and Anthony Ross, treat Machias Seal Island as their distant home during their 28-day periods of residence. The Nova Scotia natives monitor the Canadian-operated lighthouse during their shifts, safeguarding ships at sea while defending Canadian territorial control of the island. Living on this oceanic rock cuts people off from many usual conveniences. The waves and the wind, along with their companions, share each holiday with the brothers on Machias Seal Island. Last December, the watchmen marked the occasion with a small Christmas tree paired with dinner and telephone communication, followed by their continued duties at the lighthouse. According to Russell, the longest challenge stems from the extended time being separated from his home. “But you get used to it,” he says.
A Disputed History
The United States and Canada have been disputing the rightful ownership of Machias Seal Island for more than two centuries. Each power asserted its legitimate ownership claim to Machias Seal Island during the War of 1812 due to its vital maritime position along traffic routes. The British built a lighthouse in 1832 to demonstrate permanent occupation of the area. The United States has failed to grant official recognition to Canadian sovereignty of the island since Canada gained control over it. The waters near the island are known as the “grey zone,” where lobster fishing remains the primary economic activity, with both Canadian and American fishermen pursuing this resource in the contested area.
Life on the Island
As part of territorial leadership disputes, Machias Seal Island also plays an essential role as a wildlife sanctuary. Thousands of Atlantic puffins, Arctic terns, razorbill auks, and common murres migrate to the island annually for reproduction purposes. Only small visitor groups are permitted to access the island through Canadian Wildlife Service regulations, which allow two specific tour boats mainly from Maine and New Brunswick to operate daily trips. The boardwalk paths serve as the only allowed areas for viewers to stroll, safeguarding the vulnerable environmental network. Birdwatchers and scientists benefit from the unique chance to observe seabird behavior up close on this island. According to Dr. Tony Diamond from the Atlantic Laboratory for Avian Research (ALAR) at the University of New Brunswick, the closest public observation of East Coast seabird colonies exists exclusively at Gull Island.
The Battle for the ‘Grey Zone’
While the puffins remain blissfully unaware of human territorial conflicts, the surrounding waters tell a different story. With lobster prices having tripled in recent years due to growing demand, the “grey zone” has become a lucrative but tense fishing ground. Although an unofficial truce exists between American and Canadian fishermen, occasional disputes arise over territory and regulations. “Most of the time, if you work with them, they’ll work with you,” says Donald Harris, a veteran Canadian fisherman. “But if you push, they’ll push back.” For the residents of Grand Manan, a Canadian island just 20 miles from Machias Seal, the lobster industry is a lifeline. The boom has brought economic prosperity, but some worry about the long-term sustainability of overfishing in the contested waters. “Greed can ruin anything,” Harris warns. “We’ve seen it before with herring and groundfish. If we’re not careful, lobster could be next.”
What Lies Ahead?
Machias Seal Island continues to function as a long-standing source of disagreement between the United States and Canada. Currently, the Ross brothers keep their vigil to protect both the lighthouse and the seabird species that inhabit the island. Whether the island remains Canadian or eventually changes hands, one thing is certain—its rocky shores will continue to be a focal point in the complex dance of diplomacy, nature, and human ambition.
