The outcome was a petition sent to Upper Canada Legislature to provide for construction of a canal between the Twelve Mile Creek and Welland River. Unlike Merritt's original water-canal plan, the petition included plans for allowing boats to cross the Niagara Escarpment. In 1823, Hiram Tibbetts, an engineer, was employed to make a formal survey for the route. He suggested to dig a channel below the surface level of Welland River between present-day Port Robinson and Allanburg, and then follow the Twelve
