… But Only If You Follow the Rules
Replacing a fence sounds simple enough, right? Two neighbours, a bit of lumber, a weekend, and maybe a cooler of cold drinks. But once you start talking property lines, costs, and local by-laws, things can get a little prickly—especially if one neighbour wants a designer cedar wall while the other’s fine with chain link.
Across Canada, every municipality has by-laws that set the ground rules for how high your fence can be, where it can sit, and how costs are shared when a fence divides two properties. Understanding those rules—and following the right process—can save you stress, money, and maybe even a friendship.

Municipal By-Laws: The Ground Rules
Most towns and cities have fence by-laws that outline how tall your fence can be, what materials are acceptable, and how to handle shared fences between neighbours. You usually don’t need a building permit for a standard residential fence, but you do need to comply with these rules.
Typical fence height limits:
- Rear and side yards: up to 2 metres (6 ft 6 in)
- Front yards: often 1.0–1.2 metres (3–4 ft) for sightline safety near driveways and intersections
If you’re unsure where your property line is, get a land survey before digging a single post hole. A misplaced fence—even a few inches off—can create long-term headaches with property boundaries and resale value.
What’s a “Basic Fence”
Most municipal by-laws, or cost-sharing policies, define a “basic fence” as a standard four-foot galvanized chain link fence. It’s the benchmark used when splitting costs between neighbours.
Here’s what that looks like in Ontario today:
- Installed cost (materials + labour): about $12–$22 per linear foot
- For 40 feet: roughly $500–$900 total
- This includes posts, mesh, fittings, concrete, and professional installation
If you’d rather upgrade to a six-foot wooden privacy fence, that’s fine—but your neighbour only owes their share of what a basic fence would have cost. Anything above that is your preference and your expense.
Pressure-Treated Wood Fence Costs: A Step Up in Privacy and Price
A six-foot pressure-treated wood fence is a popular choice because it adds privacy, charm, and value. But it’s not cheap.
Here’s what to expect for a 40-foot run:
- Materials only: approximately $20–$30 per linear foot, or $800–$1,200 total
- Labour: about $20–$30 per linear foot, or $800–$1,200 total
- Removal of old fence: typically $5–$15 per linear foot, adding $200–$600 depending on complexity
- Total installed cost: between $1,800 and $2,800 for a standard pressure-treated fence, assuming flat terrain and easy access
If you add decorative lattice tops, premium lumber, or difficult terrain, costs can climb to $3,000+.
Notifying Your Neighbour: How to Start the Conversation
Before construction starts, you need to notify your neighbour in writing if you expect them to share in the cost. Ontario’s Line Fences Act and most municipal by-laws follow similar principles.
Here’s the proper process:
- Send a written notice (registered mail or hand-delivered with proof) at least two weeks before work begins.
- The notice should include: the fence location, proposed materials, estimated “basic cost,” and the start date.
- Give your neighbour a chance to respond or discuss the plan before work begins.
This isn’t just a courtesy—it’s protection. It proves you acted fairly and gives your neighbour an opportunity to agree, object, or negotiate upgrades at their own cost.
Sharing the Costs: Keeping It 50/50 and Fair
When both neighbours benefit from the fence—such as when it sits on the property line—the cost is typically shared equally, based on the basic fence standard.
For example:
- A basic 40-foot chain link fence costs about $900 installed.
- You decide to build a wood fence instead, costing $2,000 total.
- Your neighbour is only responsible for $450, which is half of the basic cost—not half of the upgraded fence.
It’s a fair approach that ensures no one pays for an upgrade they didn’t ask for.
When a Neighbour Refuses to Pay
Even when you’ve followed the rules and acted reasonably, a neighbour may still refuse to pay. If that happens:
- After construction, send a final registered letter within 90 days of completion requesting payment for their share.
- Allow 30 days for payment.
- If there’s still no response, you can pursue repayment through small claims court or the Line Fences Act arbitration process, depending on your municipality.
Documentation is everything. Keep copies of all correspondence, quotes, photos, and proof of notice—it can make or break your claim.
A Real-World Story: Tom and Sarah’s Fence Fix
Tom and Sarah had just bought their dream home in southern Ontario, complete with a tired old fence that had been leaning since the early 2000s. They reached out to their neighbour, Mike, about splitting the cost of a new one. Mike wasn’t interested.
Tom followed the process by the book: he sent written notice, got quotes, and waited the required two weeks. After no reply, he installed a simple chain link fence, documented the work, and later sent Mike a copy of the invoice. When Mike still refused to pay his share, Tom filed a small claims application. With his paperwork in order, he won.
By staying calm, organized, and compliant, Tom avoided a neighbour war and got his property properly enclosed.
How Realtors and Clients Can Use This Knowledge
For realtors, understanding fence cost-sharing and by-law compliance is an invaluable edge. It helps you prepare sellers for boundary-related questions and prevent disputes that could derail closings.
For homeowners, it’s about setting realistic expectations. Knowing that a new 6-foot wood fence could run $2,000–$3,000 (plus removal) means they can plan properly—and communicate confidently with their neighbours.
For buyers, it’s a chance to spot potential problems before they sign—like encroachments or fences out of compliance that might need replacing after closing.
Allen’s Final Thoughts
Good fences might make good neighbours—but clear communication, transparency, and documentation make great ones. Ontario’s fencing by-laws aren’t meant to complicate things; they exist to make sure everyone plays fair, pays fairly, and protects their property lines.
When you understand the process—notice, cost-sharing, and documentation—you take what could be a messy neighbour dispute and turn it into a cooperative improvement.
