For the first twelve years after its survey in 1848, the Toronto and Sydenham Road (T&S Road) was known as the Toronto Line. Later it was called the Owen Sound Gravel Road or just the Gravel Road. The road followed an old native trail and connected Toronto with Sydenham, now known as Owen Sound. Charles Rankin, who surveyed many parts of Dufferin and Grey counties, may have surveyed the road. Whoever surveyed the road also surveyed a strip three concessions wide on both sides of the road into 50-acre lots. On buying one lot, settlers were given the adjoining lot, an early case of "buy one, get one free". The lots were given three-digit numbers and this numbering is still reflected in the numbering of the sideroads in the area. Sideroad 290, for example, runs next to the original lot 290.
