The New Fence Crept a Foot Into the Wrong Yard

The situation

Zoltan called on a Thursday evening, the day after a surveyor he had hired to settle a separate landscaping question told him something he had not asked about but could not ignore: the new wooden fence his neighbour Attila had installed that spring sat, for most of its length, a little over a foot onto Zoltan's side of the property line.

Zoltan, a hairdresser, had owned his Thorold home for eleven years and had never had a boundary dispute with anyone on the street. Attila, a security guard, had moved in three years earlier and had replaced an old chain-link fence with a new wood privacy fence the previous fall, hiring a local contractor to do the work off a rough measurement rather than a proper survey. Neither man had thought to check a boundary before the work began, and for months the new fence simply looked like a fence, nothing about it suggesting it sat in the wrong place.

The survey Zoltan had commissioned was unrelated to the fence at first. He had been planning a small addition to his garage and needed a current survey to support the permit application, and it was only when the surveyor's report came back with a clear line drawing showing the new fence crossing onto his lot that the issue became visible at all. The intrusion was not large in absolute terms, roughly a foot at its widest point along a run of about sixty feet, but it ran the length of the shared boundary and sat directly behind the spot where Zoltan's planned garage addition was meant to go.

Zoltan's first instinct was to knock on Attila's door and point at the survey, but a coworker who had been through a property dispute of her own told him that boundary disagreements between neighbours could turn bitter and expensive fast, and that it was worth getting advice before saying anything that might commit him to a position he would later regret. He booked a consultation the same week, survey in hand, wanting to know what his actual rights were before he had a single conversation with Attila about it.

What worried Zoltan most, once the initial shock wore off, was not the strip of land itself but what fighting over it might cost. He had a rough sense, from the coworker's own experience, that a contested boundary dispute pushed to a motion or a trial could run into the tens of thousands of dollars in legal fees, survey evidence, and expert reports, on a sliver of land worth nowhere near that once you accounted for what a court process actually costs to run. That gap between the value of the land and the potential cost of fighting over it was the single fact that shaped every piece of advice we gave him from the first meeting onward.

What the law actually said

In Ontario, the boundary shown on a current, properly prepared survey generally governs, and a landowner has no legal right to build a structure, including a fence, on a neighbour's land simply because the fence looks reasonable, matches the old fence line, or was built in good faith. Attila's belief that his contractor had measured correctly did not change where the legal boundary actually sat once Zoltan's survey confirmed it.

That said, an encroachment does not automatically mean a lawsuit, and it rarely should. Ontario courts have long recognized that a landowner whose structure encroaches slightly onto a neighbour's property, without deliberate wrongdoing, is usually better dealt with through a negotiated resolution than through litigation, both because the amounts at stake in a foot-wide strip of residential land rarely justify the cost of a court process and because an ongoing neighbour relationship has real value that a lawsuit tends to destroy regardless of who wins.

There was also a factual question worth pinning down early: whether the fence had been built recently enough that any claim of long-standing use, sometimes relevant in older boundary disputes, could even arguably apply. Because Attila's fence was new, built the previous fall on top of an old chain-link line that had itself sat closer to the true boundary, there was no meaningful argument that years of open, unchallenged use had shifted anyone's rights. This was a fresh, correctable mistake, not an old one hardened by time.

The property's registration also mattered to how confidently any of this could be relied on. Ontario has moved almost all land into the land titles system, where the government-guaranteed parcel register makes a current, properly prepared survey a strong and largely final word on where a boundary sits. That is different from the older land registry system still in play for some rural and older urban parcels, where a boundary can sometimes depend on a longer chain of historical deeds and where competing claims have more room to survive. Zoltan's property was under land titles, which is part of why a single accurate survey was enough to settle the question here rather than requiring a deeper historical title search.

The practical legal path, then, was straightforward in theory: put the survey and the request to correct the fence to Attila clearly and in writing, give him a reasonable opportunity to fix it, and only escalate toward a formal claim if he refused or became unresponsive. The complication was not the law. It was that Attila's own reaction, once approached, did not stay consistent.

What we did

1. Verified the survey's reliability before relying on it for anything. We confirmed it had been prepared by a licensed Ontario surveyor and that its boundary markers matched the property's registered legal description on title, rather than simply taking Zoltan's word that the document was sound. A conversation with a neighbour about an encroachment only works if the underlying document cannot be waved away as a rough estimate, and that groundwork meant Attila had nothing credible to dispute about the boundary itself once it was raised.
2. Drafted a measured first letter to Attila, attaching the survey, explaining the encroachment in plain terms, and proposing that he move or rebuild the affected section of fence at his own cost within a set period. We framed it as a straightforward correction rather than an accusation deliberately, because starting from blame tends to make a neighbour defensive before they have even had a chance to agree there is a real problem to solve.
3. Advised Zoltan on how to handle Attila's initial cooperative response so the goodwill was not wasted. When Attila called directly and said he had not known about the boundary and would get a quote to move the fence, we told Zoltan to confirm that conversation briefly in writing and to give Attila a reasonable window to follow through, rather than pushing immediately for a signed commitment that might have read as distrustful of an offer made in good faith.
4. Addressed Attila's changed position the moment it surfaced, after he suggested, following a conversation with a neighbour named Anneke, that the old chain-link line rather than the survey should count as the real boundary. We responded in writing and without delay, because letting a shifted position sit unanswered risked letting it calcify into Attila's new default expectation rather than a passing suggestion he might otherwise have dropped.
5. Explained in plain, non-confrontational language why a new fence could not establish a new boundary, regardless of where an old fence line had once stood, tying the explanation directly to the survey and the property's registered description rather than to a general assertion of Zoltan's rights. Grounding the pushback in the same document Attila had already accepted made it far harder for him to treat the response as one-sided or aggressive.
6. Proposed a practical middle path rather than insisting on a single method, offering Attila the choice of arranging the fence adjustment himself on his own timeline or having Zoltan arrange it through a contractor of Zoltan's choosing at Attila's cost, with the quote shared in advance so there were no surprises later. Giving Attila a real choice, rather than a single ultimatum, made it easier for him to agree without it feeling like a loss.
7. Prepared a short, plainly worded boundary acknowledgment for both neighbours to sign once the fence work was complete, setting out the corrected line by reference to the survey so the matter could not be reopened later on the strength of a fading memory or a future sale of either property. Closing the file on paper, not just in practice, protected both men from the same disagreement resurfacing years down the road.

The outcome

Attila agreed to the middle path within two weeks of the second letter, choosing to arrange the fence adjustment himself rather than have Zoltan's contractor do it. The relevant section of fence was moved back onto the correct line about a month after the survey had first flagged the problem, and both men signed the short boundary acknowledgment once the work was done.

No claim was ever filed. The dispute stayed a negotiation between two neighbours, supported by clear legal advice at each turning point, and it never reached the stage where a court process would have been necessary. That outcome mattered beyond the immediate cost saving: Zoltan's planned garage addition could proceed on the correct boundary without a competing claim from Attila hanging over the permit process, and the two men continued to live next to each other without the encroachment becoming a lasting source of tension.

The case is a straightforward example of prevention rather than a hard-fought win, and it turned less on legal complexity than on handling a moment of shifting positions without letting it escalate. Attila's brief attempt to argue for the old fence line was a real risk point in the file, one that could easily have turned into a drawn-out dispute if met with an equally hardened response instead of a calm, document-backed explanation of why the argument did not hold up.
