Item - 2026.CC42.11

The Deputy City Manager, Infrastructure Services and the Chief Communications Officer recommend that:

1. City Council receive this report for information.

Following City Council direction to report back to June Council (Item - 2026.IE29.9), this report outlines the actions taken and planned to enhance the City’s approach to reporting, tracking, and communicating odour issues associated with the Ashbridges Bay Treatment Plant, following an odour event in April 2026.

Improvements include the introduction of a new service request through 311 for plant- or wastewater-related odour concerns to support consistent tracking, follow-up, and improved transparency for residents. A new communications strategy has been developed in partnership with Communications Division, which focuses on proactive community notification, supported by clearer trigger criteria and expanded outreach tools.

Toronto Water is also strengthening its internal incident escalation and notification processes to ensure more consistent application across operational events and more proactive notification for Councillors when issues arise. Planned capital investments, including primary tank refurbishments at Ashbridges Bay Treatment Plant and a future odour control facility on Coxwell Avenue, will further support the long-term mitigation of odour impacts in the surrounding community.
