NIAGARA FALLS, CANADA- FEBRUARY 20: The American side of the Niagara Falls are almost completely frozen after a prolonged period of extreme cold on February, 20 2015 in Niagara Falls, Canada. Much of the United States and Canada are experiencing unusually cold weather with record low temperatures and wind chill factors making it feel well below freezing.

A polar vortex brought Arctic temperatures to some parts of Canada on Wednesday, including the country's capital, Ottawa, and other major cities such as Toronto and Montreal. According to the Canadian Ministry of Environment and Climate Change, cold weather in Toronto on Thursday smashed a 57-year-old previous record low, with the temperature at Toronto's Pearson International Airport falling to -22 degrees Celsius on Thursday morning.
Given the plunging temperatures, local residents predict that Niagara Falls could freeze completely this winter, just as it did in January 2014.
Days of snow and thick white mist have turned the area around Niagara Falls into a crystal palace, but rushing water could still be seen flowing over the edge of the waterfalls on Friday.
Many tourists, who continued to brave the bitterly cold December temperatures to enjoy the natural beauty of the falls, believe the coldest month of the year is actually January.
A few days of extremely cold weather is not enough to freeze the rapids flowing over Niagara Falls. However, if the arctic blast continues, Niagara Falls could freeze in January 2018.
