Quick answer: While a survey is not legally required before installing a fence in Ontario it is strongly recommended. Without one you risk installing your fence in the wrong location which can lead to costly neighbour disputes and orders to relocate the fence.
If you are planning to install a fence on your property in Ontario one of the most important questions to ask first is whether you need a survey. The short answer is that a survey is not legally required — but it is one of the smartest investments you can make before a fencing project. This complete guide explains everything Ontario homeowners need to know about surveys and fence installation in 2026.
Is a Survey Required Before Installing a Fence in Ontario?
In Ontario there is no law that requires you to obtain a survey before installing a fence. However most real estate lawyers experienced contractors and municipalities strongly recommend one. The reason is simple — without a survey you have no documented proof of exactly where your property line is located and no way to guarantee your fence is in the right place.
The Line Fences Act in Ontario governs disputes between neighbours about fences on shared boundaries. If a dispute arises having a current survey is the most reliable way to resolve it quickly and inexpensively before it becomes a legal matter.
What Can Go Wrong Without a Survey?
Many Ontario homeowners install fences without a survey and later discover costly problems. Here are the most common issues that arise when a survey is skipped.
- Fence is built on a neighbour’s property causing a boundary dispute
- Fence encroaches on a municipal right-of-way or easement
- Neighbour disputes the fence location and demands relocation
- Municipality orders fence removal due to bylaw violation
- Fence blocks a drainage easement causing liability issues
- Property resale is complicated by an encroaching fence
- Cost of relocating fence far exceeds the original survey cost
Important: The cost of a boundary survey is almost always far less than the cost of relocating a fence that was installed in the wrong location. A survey is the best protection against costly fencing mistakes.
What Type of Survey Do You Need for a Fence?
For fence installation in Ontario you need a boundary survey. A boundary survey precisely locates and marks your property corners and boundary lines so you know exactly where your property begins and ends. This gives you the documented foundation you need to install your fence in exactly the right location with confidence.
| Survey Type | Best For | Includes |
|---|---|---|
| Boundary Survey | Fence installation | Property corners marked, boundary lines located, certified plan |
| Property Survey | Real estate transactions | All of the above plus structures easements encroachments |
For fence installation purposes a boundary survey is typically sufficient and more cost-effective than a full property survey. However if you also need the survey for a real estate transaction or mortgage application a full property survey may be the better choice.
How Much Does a Fence Survey Cost in Ontario?
A boundary survey for fence installation in the GTA typically costs between $1,500 and $3,000 depending on your property size location and complexity. This is a one-time cost that gives you permanent documented proof of your property lines — far less expensive than the cost of a fence dispute or relocation.

How to Resolve a Fence Dispute With a Neighbour in Ontario

Frequently Asked Questions
Do I need my neighbour’s permission to install a fence in Ontario?
You do not need your neighbour’s permission to install a fence on your own property as long as it complies with local bylaws. However it is always a good idea to discuss your fencing plans with your neighbour before starting to avoid disputes. If the fence will be on or near the shared boundary line a survey will help confirm exactly where that boundary is located.
Who pays for a fence survey in Ontario?
Typically the property owner who initiates the fencing project pays for the boundary survey. In some cases where both neighbours benefit from the survey the cost may be shared by agreement. Under the Line Fences Act the costs of a boundary fence on a shared property line are generally shared equally between neighbours.
Can I use an old survey for my fence project?
An existing survey may be acceptable if it accurately shows the current state of your property and clearly marks all boundary corners. However if the survey is more than a few years old or if any changes have been made to the property since it was completed a new survey is recommended to ensure accuracy.
