NIAGARA FALLS, Ont. — A Sudbury, Ont. couple attempting to cross into the United States via the Rainbow Bridge on Thursday to attend Saturday’s Women’s March on Washington were detained and questioned for over an hour before being allowed into the U.S.

According to a CBC News story, Amber Gazdic said that she and her husband Chris Bolestridge were told “if we got in any trouble they would personally see to it that we would never be allowed entry to the US again.” This came following more than an hour of questioning and searching by U.S. border services.

“We … were told essentially that, as Canadians, we had no right to go and participate in this march,” she told the Canadian news organization.

The Sudbury couple were not the only ones who had trouble gaining entry into the U.S.

A group from Montreal were denied access to the United States on Thursday when they tried to cross the St. Bernard de Lacolle, Que., border to attend President Donald Trump’s inauguration and the Women’s March. One of those who was turned away is a dual U.S. citizen.

Another pair were turned away at the Quebec border, as well. A U.K. National and Canadian friend traveling into the U.S. with two American friends were denied entry. The Americans were allowed to return into the U.S.

Not all Canadians headed to the inauguration were stopped or hassled. Busloads of people reportedly crossed the Rainbow and Peace bridges on Thursday en route to either the inauguration or the Women’s March with no issues.
