What makes Vaughan unique
Vaughan is one of Canada’s fastest-growing major cities and home to Canada’s Wonderland. As a York Region city it shares boards (YRDSB and YCDSB) and transportation with Markham, so closure decisions move together even when weather varies between the two cities.
York Region forecast
Vaughan snow day forecast, what to expect this winter
Vaughan is the largest city in York Region by population and one of Canada’s fastest-growing major municipalities, with a footprint that runs from Highway 7 in the south up to King Township in the north and from the Humber River valley in the west to Yonge Street in the east. The city covers a mix of mature neighbourhoods such as Thornhill and Woodbridge, newer suburban districts in Maple and Kleinburg, and the dense Vaughan Metropolitan Centre at the southern terminus of the TTC Line 1 subway. Within those boundaries the elevation rises noticeably north of Major Mackenzie Drive as the land climbs onto the Oak Ridges Moraine, which is why a single Colorado low can dump 15 cm in north Maple while leaving Thornhill with rain or a slushy mix.
School operations in Vaughan are run by the York Region District School Board (YRDSB) and the York Catholic District School Board (YCDSB), the same two boards that serve Markham, Richmond Hill, Aurora, Newmarket, and East Gwillimbury. Because the boards are region-wide rather than city-specific, a YRDSB closure call is a single decision that covers Vaughan and Markham together even when the snow band only hit one of them. The buses are run by York Region Student Transportation Services (YRSTS), the consortium that coordinates YRDSB and YCDSB routes across the entire region. YRSTS publishes its morning cancellation decision around 6:00 am at schoolbusinfo.com.
For Vaughan families the practical winter question is usually about buses rather than buildings. YRDSB closes school buildings only in the most severe storms, the January 2022 GTA blizzard and the December 2013 ice storm being recent examples, and otherwise keeps schools open while YRSTS cancels routes for snow, freezing rain, or extreme cold. Our forecast returns both probabilities separately so you can tell at a glance whether Wonderland Drive will be plowed in time, and whether the bus to Vaughan Secondary or St Joan of Arc Catholic High School is likely to run.
School boards
Vaughan school boards we model
The boards and transportation operators that make the morning closure call for Vaughan.
- York Region District School Board (YRDSB)
Public board serving Vaughan, Markham, Richmond Hill, Aurora, Newmarket, and East Gwillimbury. Region-wide closure decisions; Vaughan and Markham are always called together.
- York Catholic District School Board (YCDSB)
Catholic board covering the same York Region footprint. Closure calls typically align with YRDSB but are made independently.
- Conseil scolaire Viamonde
French-language public board serving Vaughan through schools such as École élémentaire Horizon Jeunesse. Operates separate transportation and may make different closure calls.
- Conseil scolaire catholique MonAvenir
French-language Catholic board across central-south Ontario; smaller Vaughan footprint with separate closure decisions.
Bus transportation
York Region Student Transportation Services (YRSTS) coordinates bus operations for both YRDSB and YCDSB across Vaughan, Markham, Newmarket, Aurora, Richmond Hill, and East Gwillimbury. Cancellations apply region-wide, meaning a YRSTS call cancels Vaughan and Markham routes together even when the storm only hit one city. The morning decision is posted by 6:00 am at schoolbusinfo.com.
Local weather
Vaughan’s signature winter weather patterns
The phenomena that produce most Vaughan snow days.
- York Region snow squall corridor
Squalls that organize on Georgian Bay can swing southeast and reach northern Vaughan through the Schomberg and King corridor. North Maple and Kleinburg typically see the heaviest accumulation; southern Vaughan and Thornhill often get nothing from the same band.
- Lake Ontario lake-effect spillover
During strong northwesterly wind events, the trailing edge of Lake Ontario lake-effect bands occasionally clips southern Vaughan along Highway 7. Less reliable than for Toronto or Pickering, but it can drop 5 to 10 cm on Thornhill while leaving Newmarket clear.
- Oak Ridges Moraine elevation enhancement
North Vaughan sits on the southern slope of the Oak Ridges Moraine, climbing past 230 metres in Kleinburg. The elevation gain forces extra lift into Colorado low storms and lake-effect bands, so Maple and Kleinburg routinely outpace Woodbridge and Thornhill by 30 to 50 percent in the same event.
- Colorado low storm track
The dominant major-storm pattern for Vaughan from January through March. Colorado lows track northeast across the Great Lakes and deliver the 20+ cm overnight totals that drive most modern YRDSB closures, including January 14, 2022.
- Humber and Don River valley cold-air pooling
On clear nights behind a front, cold air drains into the Humber River valley through Woodbridge and into the East Don headwaters in Thornhill. The valley floors run 3 to 5 °C colder than the surrounding plateau, so freezing rain forecast for the city can fall as ice pellets in the valleys and ice-glaze bridges and overpasses.
History
Notable Vaughan snow days in recent winters
Storms and ice events that shaped how Vaughan school boards approach the morning call.
GTA blizzard
January 14, 2022A Colorado low dropped 30+ cm of snow on Vaughan overnight with 70 km/h winds. YRDSB and YCDSB closed all schools across York Region, a rare full closure, and YRSTS cancelled all buses. Highway 400 and Highway 407 saw multi-hour closures through Vaughan.
Greater Toronto ice storm
December 21-22, 2013A freezing-rain event coated York Region with up to 30 mm of ice glaze, with Vaughan particularly hard hit along the moraine. PowerStream (now Alectra Utilities) reported widespread outages across Woodbridge and Maple, and YRDSB closed for multiple days into the holiday break.
April ice storm
April 14-15, 2018A late-season system deposited 25 mm of freezing rain on Vaughan over two days. YRDSB closed schools across York Region; tree damage in Thornhill and Woodbridge was extensive and Alectra crews worked through the following week.
Polar vortex cold snap
January 30-31, 2019Wind chills near −40 °C across York Region forced YRDSB and YCDSB to close schools for safety. Vaughan’s Humber valley sites recorded the coldest morning temperatures, with several days of YRSTS cancellations.
Toronto Snowstorm
January 2-3, 1999The benchmark GTA winter event. Back-to-back storms deposited over a metre of snow across the region in two weeks. Vaughan, then a much smaller municipality, was effectively shut down; York Region school boards closed for several days. Still the reference point for any major Vaughan snowfall.
Mid-February snowstorm
February 12, 2019Roughly 25 cm of snow fell on Vaughan over 18 hours during a Colorado low. YRDSB kept buildings open but YRSTS cancelled buses region-wide, the textbook York Region outcome for a moderate storm.
FAQ
Vaughan snow day frequently asked questions
The 7 questions Vaughan parents and teachers ask us most.
Will YRDSB close in Vaughan tomorrow?
Type your Vaughan postal code or "Vaughan, Ontario" into the predictor above. The York Region District School Board (YRDSB) makes a single closure decision that covers Vaughan, Markham, Richmond Hill, Aurora, Newmarket, and East Gwillimbury together. YRDSB rarely closes school buildings, the January 2022 blizzard and December 2013 ice storm were the most recent full closures, so the more useful number for most Vaughan parents is the bus cancellation probability shown alongside the closure probability.
Are York Region buses cancelled today?
For the official call, check York Region Student Transportation Services at schoolbusinfo.com, which posts the morning decision by 6:00 am. YRSTS handles buses for both YRDSB and YCDSB across all of York Region, so the cancellation applies to Vaughan, Markham, Newmarket, Aurora, Richmond Hill, and East Gwillimbury simultaneously. Our predictor gives you an advance probability the night before based on the overnight forecast at your specific postal code.
Do Markham and Vaughan always close together?
Yes. YRDSB and YCDSB are region-wide boards, so a closure call is a single decision that applies to Vaughan and Markham at the same time. YRSTS bus cancellations also apply region-wide. This means a heavy snow band that hits only one of the two cities will still close both, and conversely Vaughan can be closed for a storm that barely touched it because Markham or the rural north was hit harder.
Will school be cancelled tomorrow in Woodbridge or Maple?
Woodbridge and Maple are both Vaughan neighbourhoods served by YRDSB and YCDSB, and the closure call applies to the entire region rather than the neighbourhood. That said, the weather can differ a lot between them: Maple sits higher on the Oak Ridges Moraine and often gets 30 to 50 percent more snow than Woodbridge in the Humber valley. Enter your specific postal code in the predictor to get a forecast tuned to your neighbourhood’s elevation.
Does YCDSB Catholic close with YRDSB in Vaughan?
Usually, yes. The York Catholic District School Board (YCDSB) and YRDSB run on the same YRSTS bus network and historically align their closure decisions. They are technically independent calls, so YCDSB can stay open while YRDSB closes, but it is uncommon. Buses are cancelled together because the consortium serves both boards.
How does Vaughan winter weather differ from Toronto?
Vaughan averages noticeably more snow than downtown Toronto, especially in the northern neighbourhoods of Maple and Kleinburg that sit on the Oak Ridges Moraine. The elevation gain forces extra lift into storms, and Vaughan is far enough from Lake Ontario that the city does not benefit from the lake’s urban heat-island warming. A storm that falls as rain or freezing rain in downtown Toronto often falls as 10 to 15 cm of snow in north Vaughan.
Does the Oak Ridges Moraine elevation affect Vaughan snow?
Yes, significantly. The southern slope of the Oak Ridges Moraine climbs through north Vaughan past 230 metres in Kleinburg, well above the 100 metres of southern Woodbridge. That elevation gain enhances snowfall through orographic lift, especially in Colorado low storms and northwesterly squall events. Our forecast pulls hourly data at your exact coordinates so the moraine effect shows up correctly for your neighbourhood.
