Canada's largest school board says no to U-S school trips

The Toronto District School Board says uncertainty over restrictions at the border have prompted it to stop booking student trips to the U-S.
    
The public board, which has about 245,000 students, is the largest school board in the country.
    
The board says it plans to go ahead with two dozen trips that have already been approved, but says the entire group will turn back if any students with appropriate documentation are turned away.

President Donald Trump has announced new travel restrictions affecting who can enter the country, but the changes have been on hold due to several court challenges.
