Why don't you call your school or look on their webpage (if they have one) or your school district's webpage.
From my experience, if it stops snowing by midnight that should give the city enough time to clear the major streets, so you will probably have school tomorrow.
There's a very high chance that school closure may happen. All around the GTA (Grand Toronto Area) and not only Toronto Ontario. By the looks of your question, It seems like your a student. Make sure you finish all your homework and check your local school's website at 6:30 AM tomorrow morning when the school's board has come to a decision. You don't want to go unprepared when it is suddenly announced that school is open.
Here is what "The Weather Network" had to say:
Significant snowfall of 15 to 25 cm tonight and Friday. A winter storm will affect the regions tonight and Friday. Snow associated with a trough ahead of this system has spread into South-Central Ontario from Michigan with a couple cm of light snow expected in most areas this evening in a swath of regions extending from Lake Huron to Western Lake Ontario. However a significant change is expected overnight. This Texas low will intensify into a major winter storm as it approaches Southern Ontario towards morning. An expanding area of heavy snow is expected to move into western parts of Southern Ontario near Lake Huron beginning this evening then spread east across remaining regions overnight or early Friday morning. The heaviest snow will occur during the Friday morning rush hour along the highway 401 corridor from London across Waterloo region and the Greater Toronto. Heavy snow will spread quickly east during the day to affect Kingston through Brockville to Cornwall. Strong and gusty northeasterly winds will whip up the freshly fallen snow and result in very low visibility at times in blowing snow. Total snowfall amounts of 15 to 25 centimetres are likely across the regions. Snowfall rates of 2 to 4 centimetres per hour are possible during the heaviest snow, and if this occurs, near zero visibility in the heavy snow may be a significant issue to deal with. Hazardous winter travelling conditions from near zero visibility areas of heavy snow and local blowing snow are expected especially on Friday. Rapidly accumulating snow will also contribute to dangerous driving conditions. Travel plans should be changed accordingly. The snow will end in areas west of the Greater Toronto area in the afternoon, in the Toronto area in the evening and overnight in easternmost sections as the storm centre moves away.
It's not that hard to find out, turn on your local news channel and they post all the cancellations along the bottom of the screen. That's at least what they are doing right now in my area.
Yes. It's still gonna be kinda Cold & Windy. But snow won't be a problem- and all the school will be Open. :)
I live in Wisconsin and it is snowing a lot right now... It is supposed to snow like this till midnight.
