Sables-Spanish Rivers is a township in Ontario, Canada, on the north shore of Georgian Bay. It is located in the Sudbury District, approximately 70 kilometres (43 mi) west of Sudbury.

King's Highway 17, more commonly known as Highway 17, is a provincially maintained highway and the primary route of the Trans-Canada Highway through the Canadian province of Ontario. It begins at the Manitoba boundary, 50 km (31 mi) west of Kenora, and the main section ends where Highway 417 begins just west of Arnprior. A small disconnected signed section of the highway still remains within the Ottawa Region between County Road 29 and Grants Side Road. This makes it Ontario's longest highway.
