Exo Sud-Ouest sector is the bus service that operates bus routes from Montreal to Kahnawake, Châteauguay, Salaberry-de-Valleyfield, Saint-Zotique and Les Coteaux on the south shore of the St. Lawrence River in Quebec, Canada.

In the late winter 2007, the City of Chateauguay conducted a feasibility study to determine whether or not a hovercraft connection would be profitable.The suggested routes are Chateauguay/ Old Montreal and Chateauguay/ West Island. This would be one solution in regards to dealing with the repairs on the Mercier Bridge expected during the summers of 2007, 2008, and 2009.The city was also considering the option of adding a stop in Kahnawake on the existing Montreal / Delson / Candiac commuter train line.
