Right this moment, they are almost the same (46F in SF vs 37F in Toronto). Toronto winter usually goes between 5F and 40F, but summer is way warmer than SF (between 75F to 90F vs 60F to 70F in SF)
As someone born in Toronto, the weather is crap. You're right by a great lake, so it's damp/humid all year (step out of the shower and start sweating humid). Downtown is a series of giant wind tunnels, which isn't bad in the summer, but is downright chilly in the winter.
I moved to Calgary and the weather is great, nice and dry and Chinooks to warm you up during the winter.
I guess weather preferences are subjective. My wife prefers TO weather over SF weather. Her reasoning is that TO has "real seasons". I used to live in Sao Paulo. Great weather IMHO, if you're ok w/ 38C in summer. SF weather feels chilly all throughout the year IMHO. The weather inland in the Bay Area tends to be much better for my taste. YMMV.
Yes, that was around 9pm PST. Right now (9am PST) it's 47F in SF vs 38F in TO. Forecast for noon today is 53F in SF vs 38F in Toronto. It is an unusually warm winter in TO this year, though what I said about summers being warmer in TO holds true every year.
Try https://weatherspark.com to compare different cities. They have a nice visual map of how comfortable it gets throughout the year and have lots of stats on humidity, wind, sunlight etc.
Humidity is just as big a factor as temperature, and anything East if the Rocky Mountains is more humid than west of Rocky Mountains, in my experience.
