Toronto is buried in snow after a nasty winter system rolled through the region Wednesday evening, causing chaos and cancellations across the city on Thursday morning.

At least 15 centimetres of snow now blankets Toronto as city crews work hard to clean up the mess.

Even before the snow began to fall, the TTC announced heavy cuts to service, including the closure of the entire Line 3 Scarborough RT and 41 bus stops located on hilly terrain that would be difficult to service in snowy conditions.

One of Toronto's most notoriously dangerous stretches of road after a winter storm is the steep hill on Avenue Road south of St. Clair, where drivers often struggle to gain traction in heavy snow.

Avenue Rd is now a problem in #Toronto with vehicles unable to climb the hill, some sliding backwards. But no stuck #TTC buses so that's good!#Onstorm pic.twitter.com/e2m4ZwU430

City roads are treacherous, but the stakes are even higher on 400 series highways, where several major collisions were reported amid the snowfall.

Over at Toronto Pearson International Airport, upwards of 100 flights were cancelled as the local weather system coincided with a winter storm striking parts of the U.S.

The winter storm that pounded the U.S. Midwest and southern Ontario is causing major travel headaches today. Some 750 US flights cancelled as of 7:30 am EST. 100-plus flights cancelled in/out of Toronto Pearson. https://t.co/FwY5bV49aE #ONStorm #winterstorm #Toronto #Pearson

The conditions have led to school bus cancellations, but it is technically not a snow day for kids as TDSB schools remain open.

Due to weather-related delays, all buses are cancelled today, however schools will remain open.

Others made the best of a bad situation, like one person recorded on the doorbell camera of a Toronto residence, blasting by on a snowboard towed by a vehicle.

Despite the massive snowfall, Toronto was relatively lucky compared to other regions of southern Ontario, where ice accretion caused damage evocative of the destructive 2013 ice storm that rocked the province.

I have found a pocket of EXTREME tree damage in Norfolk County around the Fairgrounds vicinity. I have measured 0.6-0.7" radial ice accretion using pieces that have fallen from treetops. Flat surfaces have 1+" accretion. Trees ravaged. #ONstorm@ECCCWeatherON @southernon_wx pic.twitter.com/p1ZLpdeljV

Norfolk county was especially hard hit, with tree branches and power lines encased in a thick layer of ice.

Toronto is expected to see another light dusting of snow Thursday evening, though it looks like the worst of this system has passed, leaving what is hopefully the last heavy shovelling and plowing activity of the season.
