Depends on the road, if you live in a "Green road" (see map http://www1.toronto.ca/City Of Toro...les/pdf/2012/City_Wide Maps/city-wide_map.pdf), they won't plough it at all until 8cm has fallen.
See snow ploughing, from City of Toronto site.
I'm curious about what methodology they use to decide who gets plowed. They apparently never plow the streets near where a friend of mine lives (I believe they're the "Green roads" you talked about), but there's nothing about those streets that I can see that would make them any less "worthy" of plowing services. In fact, his street has many more homes on it than my own, so I'd hope that his street would get priority.
