Yonge Street
The construction of Yonge Street is designated as an Event of National Historic Significance in Canada. Yonge Street was integral to the original planning and settlement of western Upper Canada in the 1790s, forming the basis of the concession roads in Ontario today. Once the southernmost leg of Highway 11, linking the provincial capital with northern Ontario, Yonge Street has been referred to as "Main Street Ontario". Today, no section of Yonge Street is marked as a provincial highway.
