The MRC ensures the integrated management of the outflow of water from waterways on its territory, which focuses on the public safety. The MRC enforces its regulations governing matters relating to the outflow of waterways and plans the management of all waterways under its jurisdiction, excluding the Outaouais River and the St. Lawrence River.
For the purposes of management of the waterways for which it has jurisdiction, the MRC developed a waterway management policy.
In addition, as part of major projects carried out on its territory, the MRC acts as a link between the various stakeholders, such as cities, municipalities, government bodies, the Conseil des bassins versants de la région de Vaudreuil-Soulanges (COBAVER-VS) (English), the Zone d’intervention Prioritaire du Haut Saint-Laurent (ZIP HSL) committee (English), citizens and other stakeholders.
Agricultural Soil Retention Project
In 2016, the MRC de Vaudreuil-Soulanges launched a program to promote the retention of agricultural soils thanks to an aid package from the Prime-Vert program of the Ministry of Agriculture, Fisheries and Food of Quebec (MAPAQ).
The objectives of this project are to improve the quality of waterways by reducing the amount of sediment due to bank erosion, to reduce maintenance work required in waterways, and to improve growing conditions on many agricultural lands. It is made possible through the collaboration of agro-environmental advisory clubs, the Union des producteurs agricoles (UPA) and of the Conseil du bassin versant de la région de Vaudreuil-Soulanges (Watershed Council of the Vaudreuil-Soulanges Region – COBAVER-VS)
The MRC intends to maximize the use of MAPAQ’s aid package by seeking grants that can cover up to 90% of the cost of the works, which represents nearly $25,000 per farm business.
A personalized approach is offered to each farmer to promote the retention of agricultural soils. Here’s an overview of the steps of the project:
- Data compilation;
- Field diagnosis by an agronomist technician;
- Choice of actions to be carried out by farmers;
- Farmer-directed execution of the work;
- MAPAQ reimbursement according to grants.

Please contact the waterways department for any maintenance requests at by email at firstname.lastname@example.org or by phone at 450-455-5753 x2202, or in person at the MRC office at 280 Boulevard Harwood in Vaudreuil-Dorion.
Removing an Obstruction
The MRC must restore the normal flow of water when it is informed of the presence of an obstruction that threatens public safety.
Obstructed or collapsed culvert
|Responsible Party||Type of Obstruction|
|The MRC||Beaver dams|
|Preventative weakening of ice dams|
|The owner, as provided for in the Loi et dans la réglementation, or else the MCR will intervene at the owner’s cost||Bridge or culvert of insufficient size|
|Sediments in the waterway due to collapse of an unstable river bank and dislocation of the river bank|
|Being able to tolerate snow, branches, trash, scrap metal, etc. in the waterway|
Responsibilities of riverside property owners
As a riverside property owner, you must remove anything that can impede the flow of water, such as branches, trash, tree trunks or land subsidence. You must keep your shoreline in good condition and free of debris and keep native and natural vegetation over a minimum span of 10 or 15 meters.
The MRC intervenes when it is informed that a beaver dam threatens public safety. Following the trapping of beavers, the MRC proceeds to dismantle dams causing an obstruction on the waterway.

Identifying Waterways on Your Property
Before doing any work on what you think is a ditch, contact the MRC to check whether it is a waterway under its jurisdiction. Be aware that even the smallest natural flow could be a waterway, even if it is has been dry for some time
The exact location, location of the riparian buffer, or other geographic information should be determined by a surveyor or biologist trained in the high water line determination process.
In response to your request, the MRC will send you a map approximate location of the waterway on the property to study. The responsibility of the MRC is limited to confirming whether or not it is a waterway under its jurisdiction.
What is a waterway?
Some ditches are now considered waterways under the Law, which makes no distinction between regular or intermittent waterways and those created or modified by human intervention.
Definition of a waterway under the jurisdiction of the MRC
The MRC has jurisdiction over regular or intermittent waterways, including those created or modified by human intervention:
- Natural waterway, regardless of drainage basin;
- Waterway of natural but modified origin, regardless of the drainage basin;
- A dugout waterway that exists only because of human intervention with a drained area greater than 100 hectares.
Please contact the waterways department for any inquiries regarding the identification of a waterway by email at firstname.lastname@example.org or by phone at 450-455-5753 x2202, or in person at the MRC office at 280 Boulevard Harwood in Vaudreuil-Dorion.
