There’s been a lot of fuss in the news about how cold it is in southern Ontario this winter. It’s so cold, in fact, that portions of Niagara Falls have frozen. Surely, if the Niagara River is freezing at the Falls, a piddly little creek in Toronto would freeze solid. Seems logical. So why do many of the creeks in Toronto’s ravines continue to flow? Does the Public Works Department add anti-freeze somewhere upstream?
