We at HWDSB take the safety of our students and staff seriously and follow public health recommendations when addressing COVID-19 and ventilation.
2021 HWDSB CVRIS-EDU Ventilation Upgrades
In April 2021, the Government of Canada announced plans to invest $525.2 million towards projects through the COVID-19 Resilience Infrastructure Stream – Education Related Projects (CVRIS-EDU) as part of Investing in Canada Infrastructure Program (ICIP). In addition, the Government of Ontario confirmed its contribution of more than $131.3 million to projects across Ontario. The funding announced includes almost $450 million for HVAC upgrades and improvements to air quality.
HWDSB was successful in securing funding for ventilation upgrades and other pandemic-related projects. Ventilation improvements, such as new roof top units or classroom unit ventilators, are in the ‘Complete’ or ‘Close-out’ phase at 17 locations and in the ‘Construction’ phase at 13 locations as a result of this CVRIS-EDU funding.

Standardized Ventilation Reports
Community members can now view school-specific Standardized Ventilation Reports for our HWDSB buildings. This dashboard, which was standardized by the Ministry of Education, displays each school’s ventilation system along with other ventilation and filtration measures. Access the reports through the Excel document linked below.
To find your school, use the dropdown menu next to “School Name” and select your desired school. The content will then change to display the selected school’s information.
Other Ventilation Notes
HVAC renovations are taking place at Earl Kitchener, Parkdale, and Waterdown High. These improvements include a combination of boiler replacements, heat pump replacement, RTU replacements, and UV replacements.
We are ensuring air is being exchanged, and fresh air is entering occupied spaces. Building fresh air was increased where possible through building automation systems to maximize ventilation rates.
Currently, Board staff is ensuring that “air flushes” are completed daily before staff and students enter the buildings. Air flushes are completed by running mechanical systems two hours prior to, and two hours after leaving. Systems will continue to operate in this mode throughout the day. In addition, filters are changed as required and regular repairs and maintenance is occurring.
Read our Frequently Asked Questions section to learn more about our actions, improvements, and procedures related to ventilation.
What steps did HWDSB take prior to September 2020?
- HWDSB initiated a project to have licensed mechanical contractors go through every school and verify ventilation equipment is operating as per manufacturers’ recommendations. The actions undertaken by the consultants include:
- Check for particulate accumulation on filters, replace filter as needed if material is already on-site. Verify filters are sized and installed correctly. Clean and remove louver obstructions.
- Check all motors and fans operate correctly. Grease/oil as required.
- Check belts are tight and in good condition. Replace as required.
- Check variable-frequency drive for proper operation.
- Check drain pans for cleanliness and proper slope. Check P-trap on drain pan for proper operation. Clean as required.
- Verify control dampers operate properly.
- Confirm equipment is bringing in outdoor air and removing exhaust air as intended.
- Reports for each piece of equipment were received and noted deficiencies were corrected for September 2020. Please see the building specific reports below:
What steps did HWDSB take after September 2020?
- HWDSB ensured that air was being exchanged, and fresh air was entering occupied spaces.
- We performed “air flushes” of all spaces before occupants re-entered the buildings. This was done daily by having mechanical systems operate in “occupied” mode, which provides ventilation to the building, starting at 6 a.m. before students and staff entered the building. Systems continued to operate in this mode throughout the day.
- In addition, we purchased 150 air purifiers with filters to aid with filtration and ventilation for rooms/areas where there is insufficient air flow.
What is HWDSB doing now?
- HWDSB will continue to ensure that air is being exchanged, and fresh air is entering occupied spaces. Building fresh air was increased where possible through building automation systems to maximize ventilation rates.
- Currently, Board staff is ensuring that “air flushes” are completed daily before staff and students enter the buildings. Air flushes are completed by running mechanical systems two hours prior to, and two hours after leaving. Systems will continue to operate in this mode throughout the day. In addition, filters are changed as required and regular repairs and maintenance is occurring.
- Air changes per hour (ACH) will depend on the school and its mechanical systems. We aim for 4-6 AC, which will increase if calculating using filtered ACH rates.
- 30 ventilation projects have been funded through the CVRIS program.
- HEPA filter, also known as high-efficiency particulate absorbing filter, units will be provided in accordance with Ministry direction.
- We will continue to plan window upgrades and HVAC projects as part of our regular capital planning with SCI and SRA.
What is the status of HWDSB’s CVRIS ventilation projects?
- HWDSB received funding for 30 projects under the COVID-19 Resilience Infrastructure Stream (CVRIS) program. These projects are detailed on the Board website and the stage of the project is identified.
- The projects are a priority for the Board and have had some delays due to supply chain issues. 17 projects are complete and 13 remain under construction.
- Information on the website will continue to be updated and HEPA air purifiers continue to remain in schools where construction is underway.
How will HWDSB use HEPA air purifiers?
HEPA Supply and Distribution
- HWDSB will received 794 HEPA air purifiers for deployment for September 2021. In addition, we received $120,000 funding for additional units, filters, and other related supplies. The Ministry-provided HEPA units have been provided one per class for those that qualify.
- We purchased an additional 95 HEPA units with the additional $120,000 funding, leaving approximately $45,000 for filters and other needs.
- The Board has 1,039 high-efficiency particulate air (HEPA) filtration units currently deployed in the system (150 from last year, 794 from the Ministry of Education announcement, and 95 purchased with the additional funding). The units were provided in accordance with Ministry direction, which includes schools without mechanical ventilation and in Kindergarten spaces regardless of the ventilation system in place.
- The Board is scheduled to receive another 57 HEPA filters from the Province at the end of January/beginning of February. Although all the spaces that met the criteria for receiving a HEPA filters currently have them, Board staff is currently determining where these additional HEPA filters will be placed.
- Schools without mechanical ventilation received HEPA units in classrooms and shared spaces. These buildings (exhaust only – Tier 3, as defined by the Ministry of Education) represent approximately 20% of our schools.
- HEPA units were also placed in Kindergarten spaces, regardless of the ventilation system in place. 270 Kindergarten classrooms will receive HEPA units.
- HEPA units will run while rooms are occupied (all day) and are designed to do so. Capacity depends on fan speed and model ranging from 200-450 CADR.
- The HEPA air purifiers that the Board has are meant to service approximately 1,000 square feet per unit. Classrooms are usually approximately 750 square feet. Therefore, adding additional HEPA air purifiers to a single classroom is not required.
- The filters for the units last approximately 12 months, based on unit filter indicators and run hours. Although this means that the Board units should not require a change until this summer, staff continues to monitor the effectiveness of the filters and change as required.
Can I purchase a HEPA for my child/ren’s class?
The Ministry of Education requires school boards to use the HEPA air purifiers provided by, or purchase HEPA air purifiers through, the provincial procurement guidance of the Ontario Government.
From the perspective of fundraising, we are not permitting school councils or individuals to raise funds for HEPA units. In addition to this inventory being under the controlled guidance of procurement practices as well as the enhanced public health efforts, raising funds for these units can create inequity among some school communities. More affluent school communities may be disproportionately advantaged compared to other school communities impacted by lower socio economic conditions.
Also, once we receive any HEPA units, they require filters and the Board would have to include the annual costs of filters in their operating budget moving forward.
What HWDSB schools are Tier 3 and what does that mean?
- There are three tiers of ventilation as identified by the Ministry of Education. They are Tier 1 (supply, return, exhaust), Tier 2 (supply, exhaust) and Tier 3 (exhaust). Tier 3 schools are typically heated with radiators and have exhaust units for moving air. These schools will be receiving HEPA units.
- The CVRIS projects will upgrade full mechanical systems of six schools and move them from Tier 3 to Tier 1.

What types of filters is HWDSB using?
- MERV 13 is a rating of filter used in supply and return air systems. Not all systems can accommodate MERV 13, so we have increased the level of MERV where we can.
- Roughly 35% of our schools now operate with MERV 13 filters.
- Roughly 45% of our schools have increased MERV filter values.
- Roughly 20% of our schools (18) are defined as Tier 3 by the Ministry of Education, meaning they have exhaust systems only, which are not mechanically ventilated, and will be equipped with HEPA units.
- More school-specific information regarding filters will be shared in the Standardized Ventilation Reports on September 3.
Is HWDSB monitoring carbon dioxide (CO2) levels?
- Classrooms will not be receiving any additional CO2 monitors if the school’s mechanical systems are not already equipped with them. CO2 monitoring is not required to be installed by Code, but through new construction and renovations, HWDSB follows best practices and installs CO2 monitoring at locations that can benefit from its use.
- CO2 monitors are interlocked with HVAC units, which in turn will increase the amount of ventilation classrooms as CO2 levels increase. Not all HWDSB schools have mechanical ventilation, and therefore would not benefit from CO2 monitoring.
- HWDSB’s CVRIS projects do include the introduction of CO2 monitoring, where applicable. CO2 monitoring is only beneficial in specific mechanical systems, and not all equipment can accommodate them.
