When I was going to University in NE Ohio, the city I lived in had maybe 4 snow plows - and it snows there EVERY YEAR, ALL THE TIME.
I've never had so many snow days in my life. I never had a day off from snowfall in high school - just the occasional day that it was "too cold to go outside" so school was cancelled and we went sliding outside instead.
I lived on a deeply suburban street in northern Ontario, and it often took the snow plow an extra day to get to us because they were busy with main roads. As a result, you just go used to driving in half a foot of snow.
edit: the roads are sort of crowned in Ontario as well, but I don't think that the drainage system works as well - we just get lots of water on the road. Not hydroplaning bad, but big puddles, pedestrians beware bad.
