Quick Overview

Coteau-du-Lac sits right where the Ottawa River meets the St. Lawrence, about 60 kilometres southwest of Montreal along Autoroute 20. It's a strategic stop for RVers traveling the Montreal-to-Ontario corridor, and the town has several dump stations ready for use. some of those are free -- a solid perk for travelers who are just passing through and don't want to deal with campground check-ins or fees. The area's sani-dump and RV dump station options include both standalone facilities and campground-based sanitary dump setups near the historic canal area. The town is small but well-positioned. Autoroute 20 and Autoroute 40 both run nearby, connecting Montreal to Cornwall and beyond into Ontario. If you're heading west toward Toronto or east toward Montreal, Coteau-du-Lac is an easy pull-off that doesn't require navigating city traffic. The Lieu historique national du Canal-de-Coteau-du-Lac -- a Parks Canada site -- draws history-minded visitors, and the area along the St. Lawrence has a few RV-friendly campgrounds that serve as base camps for exploring the Soulanges region. The roads around town are flat and easy for any size rig. Route 338 runs along the river and provides scenic access to the campgrounds and dump station facilities without the stress of highway merging. Cell coverage is solid on all carriers given the proximity to Montreal. For RVers crossing between Quebec and Ontario, this is one of the last convenient dump spots before the provincial border, so it's worth planning your tank schedule around a stop here. Browse the listings below for station details and directions.

Coming from Montreal, it's about 45 minutes on the 20 with light traffic, though rush hour on Friday evenings can slow things down as Montrealers head out to their cottages in the Laurentians.

Fuel is available at the gas stations along Route 338 and at the Autoroute 20 service plazas. The nearest large grocery stores are in Les Cedres and Vaudreuil-Dorion, both about 10 minutes east. For RV parts or repairs, Vaudreuil-Dorion has a Canadian Tire and a few automotive shops that handle basic work.

Explore the Coteau-du-Lac Area

If you're stopping in Coteau-du-Lac specifically to dump, try timing it for a weekday morning when the campground traffic is minimal and you can get in and out quickly. The Parks Canada canal site is free to walk around and gives you a nice break from the highway -- the old locks and fortifications date back to the 1700s and it's a quick leg-stretch right near the river. Potable water is available at most campground dump stations in the area, so top up your fresh tank while you're there. Propane is easiest to find in Vaudreuil-Dorion at the stations along Boulevard de la Gare. If you're planning to camp in the Soulanges region, stock up on groceries and supplies in the bigger towns to the east before heading to your site, since Coteau-du-Lac itself has limited retail. Cell service is excellent throughout the area thanks to the Montreal metro proximity.
