WINDSOR, Canada – Public school officials in Windsor, Ontario last week cancelled all student field trips to the United States for the next month over fears the political climate is “unsafe” to consider border crossings.

Clara Howitt, a superintendent with the Greater Essex County school district, told the Windsor Star officials canceled student trips for February and plan to re-evaluate the decision next month.

According to the Detroit Free Press:

The cancellations include planned trips to the Holocaust Memorial Center in Farmington Hills and to see the Lion King at the Detroit Opera House. An April trip to a music festival in Washington, D.C., also was cancelled because it coincides with a planned political rally that might draw a half-million protesters and pose a safety hazard, Howitt said.

“Paramount for us is student safety … we really don’t know what will happen to our students at the border,” Howitt told the Star.

The decision to halt cross border travel stems from President Donald Trump’s executive order that bars citizens from seven countries with terrorist ties from entering the United States. And despite the fact that Canada isn’t one of those countries, and two courts have struck down the ban, Greater Essex school officials aren’t taking any chances.

Windsor West MP Brian Masse told the Star some Canadians who are dual citizens have been rejected attempting to cross into the United States, and said it’s “ironic” that the school district opted to cancel its trip to the Holocaust Memorial Center.

“If ever there was a point in which the world needed to learn about racism and prejudice and the unspeakable truths that need to be spoken, (now is the time),” he said.

Greater Essex school district spokesman Scott Scantlebury said the ban on field trips to the U.S. was implemented to ensure inclusion of the district’s many multicultural students from different countries.

“Where one person doesn’t go, nobody goes … we want to make sure nobody is excluded,” he said.

Howitt contends a group of students was turned back at the U.S. border amid heightened security following the Sept. 11, 2001 terrorist attacks, and officials do not want to repeat the experience.

“It’s just right now the uncertainly of whether all our students would be able to cross,” Howitt told The Detroit News. “So having that experience in the past, we are just demonstrating due diligence at this point of uncertainty.”

The school board opted to ban cross border travel on Monday after officials contacted U.S. border authorities, who advised that any student who was a citizen of the seven listed countries would be turned away, though the call came before recent court rulings striking down the travel ban, according to the Star.

Regardless, the board’s decision was a big bummer for many students who had raised money to travel to the U.S., including W.F. Herman Academy’s concert bands, which had planned to attend a music festival in Washington, D.C. in April. The board canceled that trip, however, after learning about a massive social justice protest planned for the capital on the same day.

“If this were a regular school trip, it would be a great trip, but it’s not a safe time for us to be there,” said Herman principal Josh Canty.

Students were “very disappointed, they worked so hard on this,” he said, “but it’s just something we’ll have to deal with.”
