By 1847, the section between Scarborough and Markham had become known as the Scarborough and Markham Road. On July 28 of that year, the parliament of the Province of Canada passed an act to establish the Scarborough and Markham Plank-road Company, which was authorized to further improve the road surface to macadamized or planked construction between Kingston Road in Scarborough and Markham Village in the north, and further north and then east to Stouffville along the Markham-Stouffville township line, a line then formed between today's Stouffville Road and Main Street Stouffville. The company was allowed to erect gates and charge tolls to pay for the work.
