Where Rougemount sits
Rougemount is the westernmost neighbourhood north of Highway 401, running from the Rouge River valley on the west to Petticoat Creek on the east, with the highway along the south edge and the CN rail line that angles northwest toward Toronto as the northern limit, per the City's profile. Rougemount Drive climbs from Kingston Road beside the valley, Altona Road is the collector linking Kingston Road with Sheppard Avenue; Twyn Rivers Drive drops into the valley at the top end. The TRREB map is generally read as the streets closest to the river; whether the 1970s subdivision west of Altona Road is counted here or under Highbush varies by guide.
