Southern Ontario: ‘Snow Day’ Forecast for Monday, December 8, 2025
/With no major winter weather expected across Southern Ontario on Monday, we are not anticipating any widespread school bus cancellations.
There is, however, a low to slight chance (10 to 25 percent) for parts of Central Ontario, including regions under the Near North District School Board, as well as Muskoka and Haliburton within the Trillium Lakelands District School Board, and North Hastings under Tri-Board Student Transportation Services.
This is tied to the small possibility of cold-related cancellations. While current forecasts do not show temperatures dropping to levels that typically prompt a cancellation, if conditions trend colder overnight, a surprise decision cannot be ruled out.
We have also assigned a low to very low chance for areas near Lake Huron and Georgian Bay, where lake effect snow is still ongoing. Accumulation should taper off through the next few hours, and with totals expected to remain manageable, the likelihood of cancellations here is quite limited.
Everywhere else, we do not expect any disruptions to bus service on Monday. So tonight’s forecast is looking like you should plan to do your homework.
Disclaimer: Instant Weather has zero authority when it comes to bus and school closures.
It is completely up to the school boards, bus companies, local authorities, and parents to decide what is best for their children. This is our best guess based on our forecast.
