A Landlord's Own Rent Increase Came Back to Cost Him Two Years Later

Fatmir raised the rent on his King City rental every year the way he thought was normal, until the tenants he had raised it on filed a claim asking for two years of it back.

The situation

Fatmir had a plan that felt entirely ordinary to him. He worked as a landscaper through the warmer months and took on long-haul driving jobs in the winter, and several years earlier he had used savings from both to buy a small house in King City that he rented out rather than sell. He managed the tenancy himself, the way he had seen other small landlords do it: an annual increase applied around the tenancy's anniversary date, calculated roughly, communicated informally by text message, and folded into the next month's rent without much ceremony. He had never registered the tenancy above the guideline formally, never applied for special approval for a larger increase, and never sent anything resembling a formal notice; he simply raised the number he asked for each year and expected it to be paid, the way he understood every small landlord he knew to operate.

His tenants, Quang and Phuong, had lived in the house for several years and had never pushed back on an increase before. They paid what was asked, assuming, as Fatmir did, that a landlord raising the rent once a year was simply how renting worked. Neither side had ever looked closely at whether the increases matched what the law actually allowed, and for a long stretch that gap in understanding cost nobody anything, because nobody was asking the question.

The plan broke when Quang and Phuong, prompted by a conversation with a friend who had recently gone through a tenancy dispute of their own, looked into what the province's guideline for allowable rent increases had actually been over the previous two years. What they found was that Fatmir's increases, applied consistently and in good faith on his part, had each exceeded the permitted guideline amount by a meaningful margin, and that the notice he had given, a text message a few weeks before the increase took effect, fell well short of the formal notice period and format the rules required.

Quang and Phuong filed an application with the Landlord and Tenant Board seeking an order that the increases be declared void and that the excess collected over the two years, an amount that added up to somewhere in the tens of thousands of dollars once totalled across both years, be repaid to them. Fatmir received the notice of hearing without any warning that a dispute was coming, and it was only then, with a hearing date already on the calendar, that he came to our office.

What the other side was relying on

Quang and Phuong's application rested on a straightforward and, on its face, strong position: the rent increases had exceeded the guideline, the required notice had not been given in the proper form, and the remedy the Board could order for that combination was a rollback of the rent to its lawful level along with repayment of whatever had been collected above it. Under the framework that governs residential tenancies in Ontario, a landlord who raises rent above the permitted guideline without applying for and receiving specific approval for an above-guideline increase, and who does not give notice in the form and timeframe the rules require, has not lawfully increased the rent at all, regardless of whether the tenant paid it without complaint at the time.

What Quang and Phuong's application did not account for, and what became the turning point of the file, was the form their own application took. In drafting it, they had characterized the entire two years of increases as a single ongoing overcharge and sought repayment calculated from the date of the very first increase, without addressing a procedural wrinkle: a portion of that period fell outside the window the Board's own rules place on how far back a rent repayment claim can reach. They had, in effect, asked for more than the process allowed them to recover, apparently on the assumption that the full two years would simply be granted because the underlying increases were plainly improper.

That overreach did not make the underlying claim disappear. The increases were still unlawful, the excess for the recoverable period was still owed, and Fatmir still faced real exposure. But it meant the case was not, as it might have first appeared to him, an open-and-shut loss for the full two years of collected overpayments. It gave us a legitimate, well-founded basis to push back on the scope of what could actually be ordered, and it meant the file's outcome would turn as much on the arithmetic of the recoverable window as on the underlying merits, which were not seriously in dispute.

There was a second layer to the arithmetic as well. Because Fatmir had never applied for or received approval for an increase above the guideline, none of what he collected could be justified as a lawful above-guideline increase after the fact; the Board does not retroactively bless an increase just because the landlord can point to rising costs once a tenant has already objected. That closed off any argument that the extra amount reflected legitimate expenses, such as the cost of repairs or higher property taxes, that Fatmir might otherwise have tried to rely on. The only genuine question left open by Quang and Phuong's own drafting was how far back the repayment order could reach, and answering that precisely, rather than conceding the full two years by default, was where the real work of the file began.

What we did

  1. Reviewed the full tenancy file and every rent increase Fatmir had applied, comparing each one against the guideline percentage that had applied in that particular year and cross-checking the dates against when each text-message notice had actually been sent, to establish precisely how much of each increase was lawful and how much was not, rather than treating the two years as one undifferentiated overcharge that would be simpler to argue but wrong on the numbers.
  2. Identified the limits on how far back a rent repayment claim could reach under the Board's own rules, and confirmed that Quang and Phuong's application, as filed, sought repayment for a period that extended beyond what those limits allowed. That single procedural point materially reduced the maximum amount realistically recoverable against Fatmir, regardless of how clearly unlawful the underlying increases were.
  3. Corrected the tenancy's rent going forward immediately, rather than waiting for the hearing, by notifying Quang and Phuong in writing that the rent would be reset to the last lawful figure effective that same month. The Board treats a landlord's prompt, voluntary correction as a meaningful factor, and it stopped the ongoing overcharge from adding to the eventual repayment figure with every further month that passed.
  4. Calculated a realistic repayment figure based on the correctly bounded recovery period, working month by month through the lawful guideline for each year against what Fatmir had actually collected, producing a defensible number well below what Quang and Phuong's application had sought, and used it as the basis for an early settlement offer rather than letting the gap between the two positions go to a contested hearing.
  5. Opened settlement discussions with Quang and Phuong before the hearing date, presenting the corrected calculation transparently, showing the underlying math line by line rather than simply a bottom-line figure, along with the going-forward rent fix already in place, on the reasoning that a landlord who visibly corrects course quickly and shows his work is in a stronger position, both practically in negotiation and before an adjudicator if talks failed, than one who waits passively to be ordered to pay.
  6. Documented every communication and correction in writing, building a clear, dated record that Fatmir had acted promptly and in good faith once the problem was identified, rather than relying on his recollection of phone calls and conversations that Quang and Phuong could later dispute. That paper trail mattered both for the settlement negotiation itself, where it supported the good-faith framing, and as a fallback record if the matter had instead proceeded to a contested hearing before the Board.
  7. Reviewed the file for any additional exposure beyond the rent overcharge itself, including whether any other tenancy obligations, such as proper receipts for rent paid or interest owed annually on the last month's rent deposit, had also been handled informally the way the rent increases had been. Catching a second, smaller issue at this stage meant it could be folded into the same settlement rather than surfacing later as a fresh complaint once the first dispute was already resolved.
  8. Advised Fatmir on proper notice procedures for any future increase, walking him through the correct notice form, the required lead time before an increase can take effect, and where to find the guideline percentage each year, so that the same mistake, applying an increase informally by text without the required form and notice period, would not recur on this tenancy or with any future one he takes on.

The outcome

Quang and Phuong accepted the negotiated repayment figure, calculated against the properly bounded recovery period rather than the full two years their original application had sought, and the matter resolved without a contested hearing. Fatmir repaid an amount in the mid five figures, a real cost and one that reflected genuine overcharging on his part, but meaningfully less than the two full years of increases would have totalled had the Board been asked to order repayment for the entire period as originally framed.

The rent on the tenancy going forward sits at the lawful figure, and Fatmir now applies increases through proper written notice on the correct timeline, a process he had never previously followed because he had never been shown what it required. Quang and Phuong remain in the home, and the relationship, strained through the dispute, settled back into an ordinary landlord-tenant arrangement once the repayment was made. The repayment itself was structured over several months rather than as a single lump sum, a term Fatmir needed given how the amount compared to what the rental property brought in, and Quang and Phuong agreed to it once the corrected rent and the good-faith steps already taken were clear to them.

This was not a case where the outcome could fairly be called a win. The increases had been unlawful, the money had genuinely been overcollected, and Fatmir owed what he repaid. What the early, accurate calculation of the recoverable window did was contain the loss to what the rules actually allowed to be claimed, rather than letting an overreaching application be granted in full simply because nobody checked its scope. It was a hard, costly lesson for Fatmir about the gap between what small landlords assume is normal practice and what the law actually requires, and about how much that gap can cost even a landlord who never intended to cheat a tenant out of anything.

What you can learn from this

  • Rent increases in Ontario must follow both the guideline percentage and a specific notice form and timeline. An increase that skips either requirement is not lawfully in effect, even if the tenant pays it without objection.
  • A tenant's repayment claim is not unlimited in how far back it can reach. Check the recoverable window carefully rather than assuming the full disputed period will be awarded.
  • Correcting an ongoing overcharge immediately, before a hearing, stops the loss from growing and can meaningfully improve your position if the matter is ultimately decided or negotiated.
  • An application that overreaches on its own remedy does not erase a valid underlying claim, but it can open room to negotiate the scope of what is actually owed.
  • Informal rent management, texted reminders, rough annual bumps, feels normal to many small landlords but rarely meets the legal notice requirements. Put every increase in the proper written form from the start.
