🧪 Test weather, not the real forecast
In much of Canada, school buses can be cancelled while schools stay open. This is a weather estimate, not an official bus cancellation; check your school board or bus service.

It reads the hourly forecast for Toronto from 6 pm to 8 am before the next school morning and turns overnight snow, freezing rain, cold at 7 am and gusty wind into a chance from 1% to 99%, in °C and cm. It’s a forecast-based estimate for tomorrow; today’s decision is TDSB’s and TCDSB’s.
Local weather
Environment and Climate Change Canada’s 1981–2010 climate normals for its Toronto station show:
| Average snowfall per year | 121.5 cm |
|---|---|
| Snowiest month | January, 37.2 cm |
| Days with 5 cm or more of snowfall | 7.7 a year |
| Coldest month (daily average) | January, −3.7°C |
A snowfall of 5 cm or more comes about eight times in an average winter, 2.5 of them in January, and the ground holds 5 cm of snow or more on 43.3 days a year. The station’s biggest one-day snowfall on record was 48.3 cm, on December 11, 1944. For a bitter, dry morning, the cold & ice day calculator is the better check: it scores wind chill at bus time.
School boards
Toronto’s two English-language boards make their own weather calls, but their yellow buses come from one shared consortium.
The public board. Its Snow/Cold Weather page says senior, transportation and communications staff check the weather and roads very early in the morning. A cancellation or closure is posted on the TDSB website and TDSB social media by 6 a.m.
The Catholic board, which shares bus routes with TDSB (TDSB’s transportation policy). Its January 25, 2026 letter closed all TCDSB schools and board sites for January 26 and cancelled buses, child care and before- and after-school programs. The letter says that, as its Inclement Weather Protocol outlines, severe weather makes closing schools necessary “on rare occasions”. We couldn’t check what TCDSB does when only buses are cancelled.
Closures
Not just because buses are cancelled: TDSB says about 93 percent of its students don’t ride school buses. Closing schools is a separate call, and TDSB says severe weather makes it necessary “on rare occasions”.
Both boards did close last winter. CP24 reported that TDSB told families shortly after 6 a.m. on January 15, 2026 that schools would be closed, a day when CP24 said almost all schools in the Greater Toronto Area were closed because of the storm. For Monday, January 26, 2026, TDSB’s notice the evening before said that TDSB, together with TCDSB, had decided “to close all schools, administrative buildings and sites to students, most staff”. CP24’s closure list that morning showed both boards closed.
Buses
Yellow buses for both boards run through the Toronto Student Transportation Group (TSTG). TDSB’s policy says the partnership shares routes to keep costs down and put fewer buses on the road.
Method
The calculator runs the published snow day formula for the next school morning on Toronto time:
These points were set for US school districts, and we haven’t compared them with past TDSB or TCDSB decisions, so their accuracy in Toronto isn’t known. A high number warns of a hard morning, not a closed school.
FAQ
Check TDSB’s Snow/Cold Weather page and TDSB’s social media, where the board says it posts any cancellation or closure by 6 a.m. This page can’t tell you today’s decision; it estimates tomorrow’s chance from the forecast.
Nobody knows until TDSB decides early that morning. The calculator above estimates the chance from tonight’s forecast for Toronto. If you’re wondering whether there is school tomorrow, check it in the evening, then check TDSB’s page by 6 a.m.
Not necessarily. TDSB says about 93 percent of its students don’t use school buses, so when buses are cancelled students can still get to school by walking or other means. Parents and caregivers decide whether to send their children.
The Toronto Student Transportation Group, a partnership between TDSB and TCDSB that shares bus routes. TDSB sends families to its website, torontoschoolbus.org, for delay notifications and route maps.
About 121.5 cm a year on average, with January the snowiest month at 37.2 cm, at the Toronto station in Environment and Climate Change Canada’s 1981–2010 climate normals. Snowfalls of 5 cm or more come on about 7.7 days a year.
No. This site isn’t affiliated with TDSB, TCDSB, the Toronto Student Transportation Group or the City of Toronto. Their announcements are the answer; this page is a forecast-based estimate.
