About 40 Mohawk protesters blocked a bridge in eastern Ontario Sunday evening in support of a nearby First Nations community engaged in a standoff with the federal government over the arming of border guards. Protesters blocked either side of the Skyway bridge, which spans the Bay of Quinte near Belleville, Ont., and links the Tyendinaga Mohawk Territory and Prince Edward County.

Shawn Brant, a well-known activist in Tyendinaga, helped organize the blockade. Brant and other Mohawks plan to stay on the bridge until the federal government makes a commitment to hold what they describe as meaningful talks with Mohawks in Akwesasne. The Akwesasne territory is located near Cornwall, Ont., east of Kingston.

Talks between Mohawk officials from the Akwesasne and the Canada Border Services Agency broke down last weekend over the issue of arming guards assigned to posts on Cornwall island, which is in the middle of Akwesasne, a territory that straddles Quebec, Ontario and New York state.

The border guards in Cornwall were set to start carrying 9-mm handguns last Monday, under a new federal policy enacted across the country. Instead, guards left their posts at midnight last Sunday, citing safety concerns, after hundreds of Mohawks set up camp near the border to protest the gun policy.

Canadian authorities then shut down the Seaway International Bridge into the United States at Cornwall last Monday. The bridge, which spans the St. Lawrence River, handles about 2.4 million crossings annually.

For the time being, travellers have been advised to use a point of entry to Prescott, which is 60 kilometres west, or the Dundee crossing, which is 17 kilometres southeast.

The Akwasasne protesters are angry about guards being allowed to carry guns, because they say it violates their sovereignty, and increases the likelihood of violent confrontations.

The federal public safety minister said Sunday the border crossing might be shut permanently unless Mohawk leaders accept a decision to arm border guards.

Peter Van Loan told CTV’s Question Period the government is examining all options, including moving the port of entry.
