Maintain, repair or replace erosion control structures on shore lands
The rules for working on existing erosion control structures such as retaining walls on shore lands in Ontario.
In Ontario, the beds of most water bodies are Crown land.
The ministry manages these lands under the Public Lands Act.
The Public Lands Act applies to the use of provincial Crown land and shore lands. There are some exceptions, including provincial parks and conservation reserves.
The Act does not apply to the use of federal lands and waterbodies (e.g., the Trent-Severn and Rideau Canal waterways).
You may not need a work permit to maintain, repair or replace erosion control structures, if you follow the rules listed below, and you register with the ministry.
You will need a work permit if you want to build a new, or expand an existing, erosion control structure.
This is a summary of the provincial laws. You can find a complete set of provincial rules under the act in:
For property within the Lake Simcoe watershed but not within the jurisdiction of the Lake Simcoe Region Conservation Authority, you need a work permit to proceed.
You do not need a work permit under the Public Lands Act, if you follow all of these rules. You:
- are the waterfront property owner or conducting work on behalf of the property owner
- keep the same length, width and footprint of the original structure
- properly install and maintain sediment controls around the area if sediments (e.g., sand, silt) will be disturbed, and remove them only when work is complete and sediments have settled
- dispose of the plants/material you remove on dry land to prevent it from re-entering the water
- use, operate or store any wheeled or tracked machinery/equipment on dry land, or on a barge or vessel
- always register your work with the ministry before work begins
- keep the confirmation of registration onsite and make it available, if requested
- do not carry out work during fish spawning season or during the time of other critical fish life stages as set out in the In-water Work Timing Window Guidelines

Waterfront property owners
You can only conduct work on shore lands directly in front of your property or where your property is fronted by a road allowance or shoreline reserve.
This diagram is for illustration purposes only.
You may also want to discuss the project with neighbours before starting work. You could be found responsible for damage to another person’s property associated with this work.
Natural shore lands
Use native trees and shrubs to prevent erosion, reduce nutrient runoff and provide habitat for wildlife.
Avoid removing wild rice.
If you suspect that the area could be contaminated, you should contact a local Ministry of the Environment and Climate Change (MOECC) Office.
Machinery should be kept in clean condition and free from fluid leaks.
Report a spill
To report a spill, call the Spills Action Centre at 1-800-268-6060.
For properties along the Ottawa River, you must contact Infrastructure Ontario Property Services for more information:
Before you start any work, find out whether additional authorizations are required.
For example, you may need to check with:
- local conservation authority
- Ontario Ministry of the Environment
- Fisheries and Oceans Canada
- Transport Canada
- local municipality/township
- Ministry of Natural Resources and Forestry for endangered and protected species
- Other provincial ministries
- Ontario One Call (to see if hydro/gas lines could be impacted)
Remember that maintaining, repairing or replacing erosion control structures on shore lands does not give you any right, title or interest in the Crown land.
