The new settlers sent a petition to the province of Upper Canada early in 1824, stating they were separated from the settlements of Yonge Street, by an impassable swamp. On January 24 the Legislative Assembly of Upper Canada made a grant for the first main road in West Gwillimbury (4 Geo. 1V., chap 29). The contract for the first corduroy road across the Holland Marsh was completed by Robert Armstrong and his sons in the fall of 1825. Connecting with other contactors sections and the previously constructed road from Kempenfelt Bay, the road became known as Penetanguishene Road. It later became part of Yonge Street, and is now Simcoe County Road 4.
