First Welland Canal was let into the Feeder and Welland Canals in November 1829. As with other locations in the peninsula, shantytowns sprung up along the Feeder Canal. These later developed into places like Dunnville, Wainfleet and Welland, among others. The Welland Canal was officially opened on November 30, 1829, exactly five years after the first turning of the sod. Two schooners, "Annie and Jane" from York, Upper Canada and "R.H. Broughton" from Youngstown, New York, left Port Dalhousie on Lake Ontario and arrived in Buffalo on the eastern end of Lake Erie two days later. "Annie and Jane" returned to Lake Ontario
Welland Canal affiliated with the canal, and was actually used to help transfer cargoes from the lake ships, which were too large for the small canal locks, to the other end of the canal (The Trillium Railway owns the railway's remnants and Port Colborne Harbour Railway). Smaller ships called "canallers" also took a part of these loads. Due to this problem, it was soon apparent the canal would have to be enlarged again. In 1887, a new shorter alignment was completed between St. Catharines and Port Dalhousie. One of the most interesting features of this third Welland Canal was the Merritton Tunnel,
