Bradford Snow Day Predictor – Simcoe County DSB and Simcoe Muskoka Catholic
Will Tomorrow Be a Snow Day?
Canada's most accurate snow day predictor
Bradford West Gwillimbury sits at the southern edge of Simcoe County, close enough to the GTA to feel major regional storms but far enough north to catch the tail end of Georgian Bay lake-effect events. The town averages approximately 150–200 cm of snow per year and shares the Simcoe County District School Board (SCDSB) with Barrie and Orillia. Its position on the Holland Marsh, with exposed flat farmland, means blowing and drifting snow is a significant closure factor.

Bradford Snow Day Triggers – What Closes Schools Here
Bradford sees a mix of GTA storms and Simcoe County lake-effect:
- Regional GTA storms: Bradford’s southern Simcoe location means it catches major storm systems that affect the northern GTA, including Colorado lows and Great Lakes systems.
- Tail-end lake-effect: When Georgian Bay lake-effect bands extend far enough south, Bradford can catch significant accumulation from events centred on Barrie and Orillia.
- Holland Marsh drifting: The flat, exposed farmland of the Holland Marsh around Bradford produces significant blowing and drifting snow that closes rural bus routes.
How Often Do Bradford Schools Close?
As part of the SCDSB, Bradford schools close approximately 6–10 days per year. Bradford sometimes stays open when northern Simcoe County (Barrie, Orillia) closes for lake-effect that does not reach as far south – check your specific SCDSB zone. January and February are peak months.

Frequently Asked Questions – Bradford Snow Days
Which school board and bus zone does the Bradford predictor track?
The predictor tracks the Simcoe County District School Board (SCDSB) and the Simcoe County Catholic District School Board. For school bus routing, Bradford sits in the South Zone (Zone 3) of the Simcoe County Student Transportation Consortium (SCSTC).
Why does the predictor show a high cancellation percentage when Bradford roads are fine?
Bradford shares its weather zone with other South Zone municipalities like Innisfil, New Tecumseth, and Essa. The predictor calculates risk for the entire zone, meaning heavy lake-effect snow or icy conditions on rural side roads outside Bradford can cancel buses for the town’s schools even if downtown streets are completely clear.
How much snow is required to trigger a high percentage on the Bradford predictor?
There is no set number, but the predictor’s percentage spikes dramatically if environmental forecasts call for 10 to 15 cm of rapid accumulation right before the morning commute, or if there is a threat of freezing rain making Highway 400 and local regional roads dangerous.
If the Bradford predictor hits 100% and buses are cancelled, can students still go to school?
Yes, schools almost always stay open for walking students and staff even when buses are called off. However, the predictor helps parents prepare for “inclement weather days” when regular curriculum lessons and tests are officially paused for the day.
What time is the Bradford snow day predictor most accurate?
The morning check between 5:00 AM and 5:30 AM is the most accurate. While checking at 9:00 PM the night before provides a helpful baseline, overnight shifts in storm tracks require final morning radar updates right before the official SCSTC announcement at 6:00 AM.
