Côte-Sainte-Catherine lock

The Côte-Sainte-Catherine lock is a navigation structure in Sainte-Catherine that lifts vessels approximately 9 meters. It allows ships to pass beyond the Lachine Rapids and gain access to Lake Saint-Louis.

This lock was built as part of a larger waterway project that opened the Saint Lawrence Seaway. It fundamentally changed shipping and commerce patterns across North America.

The lock is a gathering place where people watch cargo ships and pleasure boats pass through the engineering system. Visitors can see how important this waterway remains for daily shipping activities along the river.

The lock operates during the navigation season and can accommodate vessels up to standard Seaway dimensions. Visitors should know that operating times may vary depending on the season.

The lock is part of a sequential system where vessels undergo multiple lifting stages. After passing through here, ships can reach the nearby Beauharnois lock for an additional lift.
