Which canal connects Hamilton Harbor with Lake Ontario?

The Burlington Canal is the waterway that connects Hamilton Harbor with Lake Ontario. It serves as an important navigational link for vessels traveling to and from the harbor, allowing access to the larger body of water of Lake Ontario. The canal was constructed to provide a safer and more direct route for ships, avoiding the hazardous waters of the open lake in certain conditions.

In contrast, the Welland Canal, while an important link in connecting Lake Ontario to Lake Erie, serves a different purpose and does not specifically connect to Hamilton Harbor. The Erie Canal primarily connects the Hudson River with Lake Erie, and the Detroit Canal is not relevant in this context since it connects different bodies of water unrelated to Hamilton Harbor or Lake Ontario. Thus, the Burlington Canal is the correct answer as it specifically serves to connect the two.
