It's still interesting to think about it but don't try to imply that it's not actually cold, bitter and rough sledding here because we're "south" of London.
Because it's 8C in London right now.
Roughly the same distance further north from London and you arrive at Uppsala (north of Stockholm), and St Petersburg.
Toronto is on roughly the same latitude as Cannes, Nice, Toulouse and Monaco -- the Côte d'Azur / French Riviera.
Edmonton, Alberta is between Manchester and Leeds in England, and close to the latitude of Hamburg.
If you really want to bend your noodle, consider that Los Angeles is at the same latitude as Rabat, Morocco and Miami is at the same latitude as Luxor, Egypt.
The variation is really what makes it tricky. Sure, it's decent today. There's a predicted high of +8C, but Sunday night it's predicted to have a low of -22C. When you're outside in light clothes one day, and then need to bundle up like crazy 2 nights later... It starts to get to you.
Rain or not, at least we don't freeze our asses (so bad) over here :D
I once had a coworker from Atlanta at our office in Toronto. Overheard him on the phone talking to his wife, gobsmacked by the cold, which he said "it's just so far north!" and yet that's not the reason -- we're no further north than northern California. He happened to be here during a cold front that came out of northern Ontario. It's a classic continental climate; summer heat here is as intense as that of many southern US states.
The climate on the north side of Lake Ontario is actually milder than on the other side due to lake effect and weather patterns. Just got back from a trip to the Finger Lakes; our wines in the Niagara region are noticeably riper than those from down there.
Actually, I think the climate on the south side of Lake Ontario is a bit warmer and wetter (thus the lake effect snow). The cold air is moderated a bit as it crosses over the lakes, but it also picks up all that moisture. In fact, I think the windward side of all the Great Lakes are similar and might be in different climate zones vs the leeward side of the lakes. I know in Western Michigan for example there is a bit of a fruit belt because of this.
As someone who grew up outside Buffalo and lives in NC now, this is a big NO.
There are cold streaks (or polar vortexes or whatever the weather people want to call them now) in Atlanta and heat waves in Buffalo and these might cause temperatures to seem similar for a few days per year, but it is NOT the same.
The difference is that these cold streaks last for a couple days in Atlanta and for months in Buffalo, and vice versa for heat waves. Temperatures in the 20s (Fahrenheit, sorry) with dips lower are common for Buffalo all winter, but happen only for a few days at a time (and maybe once per winter) in Atlanta.
And same with the high temps -- temps in the 90s are expected from July thru the end of September in Atlanta, but its only a few days in Buffalo that are that way. Last summer here in Durham, NC, we set a record for days above 90 in a row that was in the high 20s, if not 30s (as in 20 or 30 days in a row). I very clearly remember that my second summer down here didn't even have nightly lows in the 80s. That just doesn't happen up North.
PS: Please forgive me for substituting Buffalo weather for Toronto. It's about the same, but I wanted to accurately represent my anecdotal experiences.
PPS: This should not distract from the fact that weather in Ontario is very similar to weather in New York, Pennsylvania, Illinois, Indiana and Ohio and maybe better than Michigan, Wisconsin, Minnesota, North Dakota, Montana, etc.
