Niagara Falls fact. It's true, there have been winters so cold in Canada that Niagara Falls froze. You can see pictures in the historic Brock Hotel in Niagara Falls (along with a picture of Marilyn Monroe visiting the Falls!!)
Niagara Falls is the collective name for three #waterfalls that straddle the international border between the Canadian province of Ontario and the U.S. state of New York. They form the southern end of the Niagara Gorge.
