It spans approximately 400 kilometers, beginning at the border of Windsor and extending eastward into the town of Cornwall. Within the GTA, this segment experiences high traffic volumes due to its central role in facilitating commuter travel, freight movement, and regional connectivity.

The highway serves a population of over six million people in the GTA, connecting key urban centers such as Toronto, Mississauga, and Markham. It is a primary route for commercial transport, significantly contributing to Ontario's economy by providing access to major industrial and commercial segments. The corridor also links to significant regional routes and transportation infrastructure, including public transit systems and major arterial roads.

Highway 401 supports not only daily commuting but also access to notable destinations along its route.
