List of east–west roads in Toronto

The following is a list of the east–west expressways and arterial thoroughfares in Toronto, Ontario, Canada. The city is organized in a grid pattern dating back to the plan laid out by Augustus Jones between 1793 and 1797. Most streets are aligned in the north–south or east–west direction, based on the shoreline of Lake Ontario. In other words, major north–south roads are generally perpendicular to the Lake Ontario shoreline and major east–west roads are generally parallel to the lake's shoreline. The Toronto road system is also influenced by its topography as some roads are aligned with the old Lake Iroquois shoreline or the deep valleys. Roads are listed south to north.

Expressways

Gardiner Expressway

The Frederick G. Gardiner Expressway, known locally as "the Gardiner", is an expressway connecting downtown with the western suburbs. Running close to the shore of Lake Ontario, it now extends from the junction of Highway 427 and the Queen Elizabeth Way (QEW) in the west to the foot of the Don Valley Parkway in the east, just past the mouth of the Don River. East of Dufferin Street, the roadway is elevated, running above Lake Shore Boulevard east of Bathurst Street, making this stretch of Gardiner Expressway unofficially the longest bridge in Ontario. Elevated sections east of the Don River were demolished and integrated into Lake Shore Boulevard.
