While this number might seem high to some, it becomes less surprising when we consider Toronto’s climate data. Cara Fisher, an associate of the Winter Cities Institute, has classified Toronto as a “moderate” winter city, along with Calgary and Minneapolis. These cities experience January highs close to 0°C (-1°C in Toronto) and lows close to -10°C (-6°C in Toronto). Temperature extremes are rare.
