Highway 400 - Definition and Overview

Highway 400, known previously as the Toronto-Barrie Highway, is a key north-south route linking Toronto to Central and Northern Ontario. As well, the route is the main route to cottages in Muskoka. Over the years, the route has been widened and extended beyond Barrie to its current terminus in Parry Sound. The current length of the highway is 209 km or 129 miles.

Continued construction will eventually extend Highway 400 to the city of Greater Sudbury in Northern Ontario, along the existing Highway 69 corridor.

This commitment was originally made in 1991 by the New Democrat government of Bob Rae. Although construction did commence at the highway's southern end, the project was curtailed by the Progressive Conservative government of Mike Harris shortly after the 1995 provincial election, with construction ending at the highway's current terminus in Parry Sound.

The continued construction to Sudbury was subsequently reinstated by Ernie Eves in 2002. In 2004, construction began on the segment from Sudbury to Estaire, and route planning studies were completed for the Estaire to Parry Sound branch. Although the timetable may be subject to change, the construction is currently scheduled to be completed in 2013.
