East of Winnipeg, the highway continues for over to Kenora, Ontario. At the provincial border, the expressway downgrades to an arterial highway and the numeric designation of the highway changes from 1 to 17. It is signed with a provincial shield along with a numberless TCH sign and continues as an arterial highway along the main route across Northern and Eastern Ontario until upgrading to a freeway at Arnprior Near Ottawa. In Kenora, the Trans-Canada designation includes both the main route through the city's urban core and the Highway 17A bypass route. The existing branch from Kenora continues east for to Dryden. A second branch extends southward along Highway 71 from Kenora to Chapple, then eastward along Highway 11 to Shabaqua Corners, where it reunites with Highway 17.
