'It will be chaos': Canada's Niagara region declares state of emergency due to solar eclipse. Up to a million people will be present, a colossal figure considering that 14 million people visit the region each year.

Many enthusiasts plan to travel several thousand kilometers across Canada to be there at 3:20 p.m. local time, when the moon's shadow will cover the sun for three to four minutes. For Canada, this is the first total solar eclipse since 1979, with the next one expected in 2044.
