Freeway portions are rare compared to the length of the Trans-Canada Highway network. They exist over significant distances in British Columbia's Lower Mainland, in Ontario and Quebec where the network overlaps portions of those provinces' 400-series highways and Autoroutes, across all of New Brunswick, and in the western part of Nova Scotia. In other cities, the highway is instead forced onto busy arterial streets with traffic lights. Examples of this are where the route passes through Victoria, Nanaimo, Kamloops, and Salmon Arm. TCH-designated freeway bypasses exist around Winnipeg and Calgary, although Highway 1 still passes through these cities on surface streets.
