Côte-Sainte-Catherine lock

The Côte-Sainte-Catherine Lock raises vessels 9 meters above the water level, enabling safe passage beyond the Lachine Rapids toward Lake St. Louis.

The construction of this lock section transformed maritime commerce along the Saint Lawrence Seaway, establishing a vital connection for North American waterborne trade.

The lock represents a center of maritime activity where visitors gather to watch cargo ships and pleasure boats navigate through the engineering system.

The lock operates throughout the navigation season, accommodating vessels up to standard Seaway dimensions with a channel length of 21 kilometers.

This lock forms part of a sequential system where vessels rise 30 feet before proceeding to Beauharnois Lock for an additional 41-foot elevation gain.
