'Ice Day' Forecast: Another Freezing Rain Risk Threatens School Bus Cancellations in Southern Ontario on Wednesday
/While Central Ontario continues to recover from the devastating ice storm that struck over the weekend, yet another round of freezing rain is expected to impact Southern Ontario throughout the day on Wednesday. In the wake of the storm, widespread damage and ongoing power outages have forced several school boards to extend closures, with more potential disruptions likely as another system moves in.
The Trillium Lakelands District School Board (TLDSB) has confirmed that all schools will remain closed for a third consecutive day on Wednesday, April 2, 2025, due to extensive power outages still affecting the region. This closure comes as crews continue efforts to restore electricity and ensure school facilities are safe to reopen.
The Simcoe Muskoka Catholic District School Board has also announced multiple school closures for both Wednesday and Thursday. In the District of Muskoka, Monsignor Michael O’Leary, St. Dominic, and Saint Mary will remain closed. In Orillia, the following schools are affected: St. Bernards, Monsignor Lee, Notre Dame, Patrick Fogarty, and Foley.
Meanwhile, the Kawartha Pine Ridge District School Board (KPR) is planning to reopen schools on Wednesday, but some locations will remain closed due to localized outages. A complete list of affected schools is available on the board’s website: KPR School Closure Update.
Similarly, the Simcoe County District School Board (SCDSB) has announced that some schools will stay closed on Wednesday. Additionally, schools in Orillia will remain closed on Thursday as recovery continues. A full list of school closures can be found here: SCDSB Alert.
On top of these closures, there's growing concern over potential school bus cancellations across parts of Southern Ontario as Environment Canada has issued widespread freezing rain warnings in advance of this next wave. Rural school boards northwest of the Greater Toronto Area (GTA)—including Bluewater, Upper Grand, and Simcoe County—are facing the highest risk of bus disruptions. Freezing rain is expected to begin in the late morning and could significantly impact afternoon bus runs.
These regions currently face an estimated 75% chance of an “ice day” on Wednesday. However, the timing of the storm means school boards will need to make proactive decisions, as the worst conditions may arrive after morning transportation has already taken place.
In Eastern Ontario, freezing rain is also in the forecast, though it’s expected to begin later in the day. With the storm arriving after the afternoon commute, most buses will likely run as scheduled on Wednesday. That said, the risk of cancellations rises for Thursday morning as freezing rain is expected to continue overnight and could make for slick travel conditions at the start of the day.
For those in Deep Southwestern Ontario and the Golden Horseshoe, freezing rain is expected to be minimal. With temperatures hovering above freezing, most of this region will avoid major impacts, and school buses are expected to operate as usual.
