The expansion of Highway 427 is a 10.4-kilometre addition to one of Toronto’s 400-series highways, which currently runs from the Queen Elizabeth Way north to Highway 7 in the city’s west end. There are two sections to the project. The first is the widening of the highway from Finch Avenue to Highway 7 (four kilometres), expanding the highway from four and six lanes to eight lanes. This will include the addition of high-occupancy toll (HOT) lanes. The second section is the 6.4-kilometre extension of the highway from Highway 7 to Rutherford Road. This includes the creation of six- and eight-lane highway sections and three interchanges..

In 2018, work was done to clear the land north of the current highway, and bridge and culvert installation has begun at multiple points throughout the 10.4-kilometre extension. In 2019, following steady progress, the first section of paving has begun.

Completion of the project is expected in 2021.
