Prior to opening the arena to users in the fall, tests are performed to ensure the building is safe to occupy. This process was initiated after a Designated Substance Survey of the Millbrook arena conducted by engineering consultant Cambium Inc. in 2023 identified the presence of mould. At that time, laboratory results indicated no significant risk in the indoor air quality, but annual testing to monitor the issue was recommended.
This September, test results revealed an increase in airborne mould over the 2023 results, triggering additional tests to be sure the facility was safe to occupy. In the interim, the facility remained closed to avoid any potential health risk to users who are primarily children and youth. This decision was supported by legal advice from the township’s solicitors.
Cambium proceeded to perform a Mould Assessment and conduct additional air and bulk sampling throughout the Arena, including the areas used for sports teams. Their findings and staff recommendations about the facility were presented to Council in a closed session on December 16th. Cambium’s report dated December 6th describes extensive mould growth across building materials and surfaces, as well as high airborne mould spore concentrations.
The report described extensive mould growth across building materials and surfaces and high airborne mould spore concentrations, posing potential health risks. It explained that mould removal would be required on drywall finishes, acoustic ceiling tiles, wood trim, fibreglass insulation and vapour barrier. Surfaces including concrete, removable rubber flooring, and all stored items throughout the building would have to be disinfected, along non-porous materials and HVAC systems including ductwork and all air handling equipment was required. Finally, the sources of moisture would need to be repaired before finishes were replaced. Additional air quality testing post-remediation was recommended to confirm that the remediation had actually worked and that health and safety was protected.
Based on these findings, Bryan Barry Associates, a structural engineering firm, was retained to complete an “order of magnitude” budget for the work required for the mould remediation. Their estimates of the costs of remediation required to restore the arena to a useable state would be approximately $1.91M of hard construction costs and $2.63M with modest contingencies to proceed with the remediation to restore the Arena’s functionality status quo.
Based on those findings, Council decided that the Millbrook Arena will remain closed.
