I dont know how people ever settled there.
Some years they vacillate between -10C and 4C causing ice to melt to water and then refreeze, nature's jackhammer to any surface cracks in the asphalt road resulting in a city budget line item for "springtime pothole fixing".
Once in awhile, the temps will drop to below -20C for several days/weeks. Not as bad as midwest USA/Canadian prairies winters requiring a heater for your car engine block, but going outside is laborious and painful for long periods.
If you look at a map of Europe, Toronto's latitude is similar to Milan's. So most of Europe has more darkness in winter than Toronto.
I would argue the darkness in winter in Toronto is pretty average compared to most places in "the West". Its the winters that are nasty, although by Canadian standards not too bad. That tells you a lot of about Canada regarding winter weather.
Embrace the winter! skating, skiing, hiking, etc... Read more, cook more. etc..
