First Welland Canal points on the Lake Erie shore, and also offered a natural harbour for the ships waiting to enter the canal. The new part of the canal was to run in a fairly straight line, except for a stretch where it followed a local ravine and a creek to minimise required excavation of hard rock in the area. The Welland Canal Company obtained a loan of 50,000 pounds from the Province of Upper Canada. Construction started soon after, but it was delayed by rain, difficulty in clearing land, and a cholera outbreak in 1832. Neither the Wainfleet Marsh nor the rock
Welland Canal first canal ran from Port Dalhousie, Ontario on Lake Ontario south along Twelve Mile Creek to St. Catharines. From there it took a winding route up the Niagara Escarpment through Merritton, Ontario to Thorold, where it continued south via Allanburg to Port Robinson, Ontario on the Welland River. Ships went east (downstream) on the Welland River to Chippawa, at the south (upper) end of the old portage road, where they made a sharp right turn into the Niagara River, upstream towards Lake Erie. Originally, the section between Allanburg and Port Robinson was planned to be carried in a subterranean tunnel.
