The City of Toronto is taking a proactive approach to managing the rehabilitation of the Gardiner to keep the roadway in safe and operable condition. City staff had originally selected an AFP model for the project, but announced in December of 2016 that they would no longer look to that model.

In 2016, the cost of the project escalated to more than $3.6 billion, more than $1 billion more than the original cost. However, city staff revamped their approach to the project, announcing that doing so would reduce the overall cost to $2.3 billion.

The proposed plan addresses the rehabilitation of the expressway, extending from Highway 427 to the eastern limit at Logan Avenue, including the 11-kilometre at-grade section from Highway 427 to Dufferin Street with its 32 bridges and structures, and the seven-kilometre elevated section from Dufferin Street to Logan Avenue with 335 spans. It incorporates the change of scope for the rehabilitation of the Gardiner Expressway east of Jarvis Street based on the future outcome of the EA.
