… Lines in the Sand: How to Handle Property Line Disputes Without Losing Your Cool
Few things can sour a cup of morning coffee faster than a knock at the door and your neighbour saying, “You’re on my property.” Whether it’s a fence, a shed, or even a few inches of driveway, property line disputes are some of the most common—and emotionally charged—conflicts between homeowners. They don’t just stir up tension; they can affect your property’s value, your enjoyment of your home, and even future financing or resale.
The good news? With a bit of knowledge, communication, and documentation, you can keep your peace (and your property).

Why Property Line Disputes Happen
It usually starts innocently enough. A fence gets replaced, a new garden shed pops up, or someone trims a hedge that doesn’t actually belong to them. Over time, many homeowners assume that the existing fence or landscaping marks the true boundary—but that’s not always the case.
Older properties often have fences that were installed close enough decades ago, and municipal records can be vague. Without a current land survey, no one really knows where one lot ends and the next begins.
These misunderstandings can simmer quietly for years—until something changes. That’s when emotions flare and “close enough” suddenly becomes “you’re trespassing.”
How to Prevent Disputes Before They Start
The best way to handle a property line dispute is to make sure it never happens in the first place. Here’s how:
- Get a land survey before building, fencing, or landscaping along any boundary. A licensed Ontario Land Surveyor will mark your exact lot lines with metal stakes or pins.
- Communicate early and clearly with your neighbour before starting any major work. A friendly chat—or better yet, a written notice—goes a long way.
- Stay within your boundary. Even a few inches over the line can trigger problems later, especially if the property changes hands.
- Keep records: Surveys, quotes, emails, and photos create a paper trail that protects you.
An ounce of prevention here can save thousands in legal fees later.
When Your Neighbour Disagrees
Let’s say you’ve done everything right. You’ve got a recent survey, you’re following the exact boundary, and you’ve even shared your plans ahead of time. But your neighbour still insists the fence or structure is on their land.
First, stay calm. This is a civil issue, not a personal attack. The goal is to solve it, not win it.
- Step back from the argument. Avoid debating boundary law at the fence line—no one wins that battle.
- Show goodwill. Offer to have both parties meet with your surveyor or review the property documents together.
- Document every conversation. Keep notes, dates, and details. It’s not about paranoia; it’s about protecting yourself if things escalate.
- If needed, contact your lawyer or surveyor for written confirmation of the boundary. In most cases, professional validation settles the issue quickly.
What Happens if Your Neighbour Calls the Police
This happens more than you’d think. Your neighbour doesn’t like where the new fence is going and calls the police, hoping they’ll “make you stop.”
Here’s the reality: the police aren’t there to determine property lines. Their role is to keep the peace, not to arbitrate civil disputes.
When officers arrive, they’ll usually:
- Speak with both parties to assess if there’s any criminal behaviour (trespass, vandalism, harassment).
- Determine if anyone’s safety or property is immediately at risk.
- Advise both parties that boundary issues are civil, not criminal, and suggest resolving them privately.
If you calmly explain that your work is based on a recent professional land survey, that typically satisfies the officers that you’re acting responsibly. They’ll almost always suggest that the disagreement be handled through legal or survey channels, not the police.
Do You Have to Show the Police the Land Survey?
No, you are not legally required to show your land survey to the police.
That document is your property, and unless there’s a court order, no one—not your neighbour, not the police—can compel you to hand it over.
However, there’s nothing wrong with voluntarily showing the survey if it helps calm the situation. You might hold it up, point out the survey stakes, or briefly explain that you’re following your official boundary markers. That transparency can go a long way toward de-escalating things.
If you’d rather not, you can simply say:
“I’m building along the official boundary confirmed by a licensed Ontario Land Surveyor. This is a civil matter, not a criminal one, and I have full documentation.”
That’s polite, professional, and enough to satisfy everyone that you’re not acting recklessly.
A Real-World Example: The Case of the Fence and the Flashing Lights
A homeowner I once worked with—let’s call him David—had just replaced a crumbling backyard fence. He’d paid for a survey, sent written notice to his neighbour, and even offered to split costs. But when construction started, the neighbour was convinced the new posts were over the line and called the police.
When officers arrived, David calmly explained that he had a licensed survey and was following it exactly. He didn’t hand over the documents, but he pointed to the visible survey stakes and explained the process. The officers quickly realized it was a civil matter, advised both parties to settle it privately, and left.
David finished his fence the next day—and later told me that the professionalism and calmness of his response made all the difference.
How Realtors and Clients Can Use This Knowledge
For realtors, understanding how to handle boundary concerns can be a real differentiator. A client who’s buying a property with an old fence line will appreciate an agent who knows how to recommend a new survey or explain the basics of cost sharing. It shows expertise, not just salesmanship.
For homeowners, this knowledge prevents panic and legal overreaction. Knowing that police aren’t there to “take sides” lets you focus on keeping calm and protecting your interests the right way.
For buyers, asking whether a property has a recent survey can help them avoid future disputes—especially in established neighbourhoods where fences have “migrated” over the years.
Allen’s Final Thoughts
Property line disputes are emotional because they touch something deeply personal—your sense of home and ownership. But staying level-headed, documenting everything, and relying on professionals instead of assumptions keeps things from spinning out of control.
If you’ve invested in a land survey, use it confidently and responsibly. You don’t owe it to everyone to show it, but you do owe it to yourself to stand by it.
As a mortgage agent, I help homeowners look at the big picture—not just rates and approvals, but the long-term protection of their investment. Whether you’re refinancing to fund repairs, preparing your home for sale, or dealing with a neighbourly disagreement, I can connect you with trusted surveyors, appraisers, and legal professionals to guide you through it smoothly.
Because at the end of the day, good fences—and calm, informed homeowners—really do make good neighbours.
