Locks in any canal serve to raise or lower a ship to the level of the water in the next segment of the canal so it may continue through. They are used when an elevation change is too severe for a natural navigable waterway to exist.

The St Lawrence Waterway has many locks what do locks do why are they needed on some canals but not on others'?

Locks on canals are used as a means of effectively going up or down hill. Water will always find its own level, therefore letting water flow into a system of locks allows gradients to be navigated by the vessels using the waterway. The number of locks will depend on how flat or otherwise the land needed to be passed through!
