Illegal Migration to the U.S. Now People Are Heading to Canada.

The pre-dawn call by U.S. border agents to their Canadian counterparts was shocking: A group of nine people, most of them children, were about to enter Canada on foot.

On Feb. 3 at 6:16 a.m., when the group was spotted, the border between Alberta and Montana was brutally uninviting, covered in snow, dark with a temperature of minus 17 degrees Fahrenheit.

Grainy night-vision images captured by Canadian border cameras showed two little girls in pink winter wear holding a woman’s hand as they trudged through the snow. More children followed in a line. Another adult dragged two suitcases.

The quick intervention by the Royal Canadian Mounted Police crew that found the group was the result of a newly beefed-up border presence across the vast frontier between the United States and Canada. At 5,525 miles, the border is the world’s longest.
