Inclement Weather Procedures

There may be times during the school year when it is necessary to cancel student transportation services due to bad weather. In some cases, the decision may be made to close schools.

School bus delays and cancellations

Transportation to and from school is provided by Service de transport de Wellington-Dufferin Student Transportation Services (STWDSTS). STWDSTS has inclement weather procedures for school buses which are common for all five school boards in the Wellington-Dufferin region.

The decision to cancel buses is made by STWDSTS after consultation with the Bus Operators. The school board does not make the decision to cancel buses.?

The STWDSTS website contains the most up-to-date information on school bus delays and cancellations. Cancellations will also be tweeted @stwdsts. An email will be sent to those subscribed to STWDSTS delays and cancellations.

STWDSTS will post information on bus cancellations on their website by 6:30 a.m. Information on school closures due to bus cancellations will also be posted to the STWDSTS website.

STWDSTS defines four divisions across Upper Grand for transportation services and notifies the public of delays and cancellations by division:

Information on transportation cancellations or school closings due to severe weather is also made available through local radio stations.

In the event of a school closure that is not related to a bus cancellation, information will be posted on the board website and the website of the affected school.

In a situation where school buses are cancelled but schools are open, parents should always assess weather and road conditions and make their own decision to send their children to school, or not. Parents are not expected to drive their children to school in bad weather.

Extreme weather during the school day

The Upper Grand District School Board has additional extreme weather procedures in place for its own schools. The board’s Senior Administration provides direction to principals to deal with isolated weather incidents, as required. For additional information on extreme weather conditions speak to your school principal.

Recess/Lunch during conditions of extreme cold

At the request of principals, a specific wind chill standard has not been adopted by the Upper Grand District School Board to determine if students should be kept indoors at these times. Principals are required to be sensitive to the safety and well-being of students during periods of severe weather. The decision to keep students in during recess, lunch or nutrition break or to shorten their time outdoors is made by the principal or designate of each school using sound judgment and in consideration of the following:

Fire alarm procedures in winter

If a school must be evacuated during the winter months as a result of a fire alarm, fire, or other emergency situation, principals follow these guidelines to ensure student safety from smoke and possible fire, and exposure to winter weather conditions:

You can help ensure your child’s safety by providing a pair of shoes to be worn in the school during winter and periods of inclement weather, and by reminding your child of the importance of wearing shoes at all times in school.

Bus cancellations and school closures due to extreme cold weather

Each morning, the general manager of STWDSTS will assess the temperature in all four divisions of Upper Grand District School Board using Environment Canada’s Wind Chill Index by 5:15am. If the temperature is forecasted to reach -35°C or colder with wind chill at 7am, he/she will inform the board’s Director of Education or designate.

STWDSTS will make the decision to cancel buses by 5:30am and, if buses are cancelled, will post the announcement to the STWDSTS website by 6:30am. Buses may or may not be cancelled, and the decision is made by STWDSTS based on a number of factors.

When the 7am forecasted temperature is -35°C or colder with wind chill, schools may or may not be closed. The decision to close schools is a joint decision of the Directors of Education of the Upper Grand and Wellington Catholic District School Boards with Board Chairs.

If the decision is made to close schools, an alert will be posted on the board and school websites, and local media will be alerted.

Risk of frostbite in extreme cold weather

Parents and guardians should be aware that frigid temperatures present a risk of frostbite within minutes of skin being exposed. Environment Canada warns that when the temperature is between -28 to -39°C, exposed skin can freeze in just 10 to 30 minutes.

Frostbite is a severe condition where the skin and underlying tissue are frozen due to exposure to the cold. Skin appears white and waxy and is hard to the touch. Skin may also feel numb. Environment Canada warns that frostbite can be quite serious and advises that if frostbite occurs, seek medical help, do not rub or massage the area and do not apply direct heat to the skin. Rather, gradually warm the area using body heat or warm water.

Parents and guardians should ensure their children are dressed properly for frigid temperatures.

School crossing guards

Additionally, parents and guardians should be aware that municipal crossing guards may not be providing service as a result of the extreme cold temperatures. Each municipality determines how it handles crossing guards and severe weather. Please see below for general information regarding your municipality’s procedure, and please contact your municipality if you have additional questions.
