Construction for a new overpass on the Ontario Line subway project in Toronto may require a temporary closure of the Don Valley Parkway. Metrolinx CEO Michael Lindsay acknowledged the possibility, stating that "massive works" are involved in building the new crossing. The Ontario Line, announced in 2019, aims to connect Don Mills and Eglinton to Ontario Place, with an estimated completion in the early 2030s at a cost exceeding $27 billion.
Officials emphasized that coordination with partners to minimize disruption is a priority. However, opposition critics have voiced concerns regarding the potential impact of a closure on the major Toronto thoroughfare, questioning the planning capabilities for such a significant undertaking.
