What canal connects Hamilton Harbor with Lake Ontario?

The Burlington Canal is the correct answer because it is specifically designed to connect Hamilton Harbor with Lake Ontario. This canal enables boats and ships to transit between the harbor and the lake, facilitating marine traffic and commerce in the region.

The Welland Canal, although a significant waterway in the region, primarily serves to connect Lake Ontario with Lake Erie and bypasses the Niagara Falls, rather than linking directly to Hamilton Harbor. The Erie Canal, located further east, serves a different geographic area altogether, facilitating trade between the Hudson River and Lake Erie. The St. Lawrence Canal is also not relevant, as it primarily connects the Great Lakes to the St. Lawrence River and is situated further downstream from Lake Ontario. Thus, the Burlington Canal serves a unique and specific function in connecting Hamilton Harbor to Lake Ontario.
