Fresh Air in Schools in Colder Weather

The TDSB continues to do everything we can to help slow the spread of COVID-19. Daily self-assessments, regular hand washing, mask wearing and physical distancing are some of the most important things we can do. In addition, according to Toronto Public Health, increasing fresh air is an important strategy in our schools and classrooms.

Over the past few months, the TDSB has checked all mechanical HVAC systems to ensure they are operating as designed, increased the frequency of filter changes, adjusted systems to increase the amount of fresh air and reduce recirculation, added portable HEPA air filter units in classrooms where mechanical ventilation is not an option, and opened windows where possible.

As we head into the colder months of the year, open windows will continue to be an important step to increase fresh air in classrooms and schools. Toronto Public Health is recommending that windows in classrooms should be opened for a period of time, at different points of the day to introduce fresh air into the space and increase air flow. While heating systems will be turned up, we still expect that schools will be cooler than normal.

We recognize it is very much a balance between introducing more ventilation at various times during the day and maintaining a comfortable indoor air temperature in classrooms. Please keep this in mind as your child gets ready for school each day by considering an extra layer of clothing to ensure comfort throughout the day.

Thank you for your continued support of our efforts to slow the spread of COVID-19 and keep our schools safe for staff and students.
