Re-opening of Item 2025.EX23.3 - Metrolinx Ontario Line - Temporary Lane Closures on the Don Valley Parkway and F.G. Gardiner Expressway and Temporary Delegation of Authority - by Councillor Paula Fletcher, seconded by Councillor Frances Nunziata

This road closure window is no longer achievable due to supply chain and fabrication delays. As a result, the bridge fabricator has re-sequenced work, and the earliest achievable fabrication date is October 20, 2025. This does not provide sufficient time to complete the required site works within the previously approved road closure window. To enable successful completion of the trestle installation, the road closure window must be extended to November 29, 2025. Accordingly, a reopening and amendment of Item EX23.3 is required. The revised closure will be coordinated with concurrent major events, including Remembrance Day and the Santa Claus Parade, to avoid conflicts. It will also be coordinated with the Eastern Avenue Bridge Rehabilitation. With the subject City Council approval, future temporary lane closures for the Ontario Line Lower Don Bridge remain unaffected. Reason for Urgency: Temporary lane closures are imminent, and updated City Council authority is required at the October Council meeting to maintain project schedule and prevent cascading impacts to subsequent construction stages.
