The seller's lawyer sent one line, and it changed the whole deal

Three days before closing, Dilshan learned the vacant Sarnia rental he was buying had someone living in it, on a lease nobody had disclosed. What followed tested how firmly a promise of vacant possession actually holds.

The situation

Three days before closing, an email arrived from the seller's lawyer, one line long: there is a tenant currently occupying the property, and the seller wanted to discuss timing. That was the entire message. No explanation of who the tenant was, how long they had been there, or why nobody had mentioned it during the two months since Dilshan's offer had been accepted on a property sold explicitly as vacant.

Dilshan works as a firefighter, and the Sarnia property was meant to be his first investment beyond his own home, purchased in the $550,000 to $850,000 range with a plan to do some light renovation before renting it out at current market terms. His wife Ishara, a mortgage broker, had helped him work through the numbers and had been the one who first flagged, when the email came in, that a vacant-possession deal with an occupant already living there was not a small wrinkle to smooth over on a phone call.

The seller, Dewi, had listed the property with an agent's description stating clearly that it would be delivered vacant on closing. Dilshan had structured his financing, his renovation contractor's schedule, and his own plans around that promise. An occupied property, especially one with a tenancy the seller had apparently not disclosed at all, was a different asset with a different set of obligations attached to it, whether or not either side had planned for that.

Dilshan called our office the same afternoon the email arrived, with the closing date still on the calendar and no clear sense of whether it should stay there. He was not looking to walk away from the deal. He wanted to know whether the property he was about to own would actually be his to use the way he had planned, or whether someone else's legal right to live there was about to become his problem regardless of what the purchase agreement said.

He had put real thought into this purchase before ever making an offer. Between shifts at the fire hall, he had toured a handful of properties, run the numbers with Ishara at the kitchen table more than once, and settled on this one specifically because vacant possession meant he could do the renovation work he wanted before ever dealing with a tenant, rather than inheriting someone else's arrangement on day one. That plan, more than the price or the location, was the reason the one-line email from Dewi's lawyer landed as hard as it did.

What was actually at stake

The core legal issue was straightforward once we confirmed the facts: a residential tenancy in Ontario is not something a landlord can simply end by selling the property, and it does not need to be registered anywhere to bind a new owner. If a genuine month-to-month tenancy existed, Dilshan, as the buyer, would step into the seller's position as landlord automatically on closing, regardless of what the agreement of purchase and sale said about vacant possession. A promise of vacant possession in a contract is a promise between seller and buyer; it does not, on its own, override a tenant's legal right to remain until the tenancy is properly ended.

That meant the seller's obligation to deliver the property vacant was real and enforceable, but it came with a process attached. Ending a residential tenancy requires proper notice, given far enough in advance, and in some circumstances the tenant's agreement or a hearing before the tenancy is legally terminated. A seller cannot simply tell a tenant to leave because the property is sold. If the tenant had moved in recently and had not been given proper notice at all, the risk was that the promised closing date would collide directly with a process that takes real time to complete.

The stakes for Dilshan were financial as well as legal. His mortgage commitment, his renovation contractor, and his own planned move on some of the work were all tied to the closing date. A tenancy that could not be lawfully ended in time meant either an inherited tenant Dilshan had never agreed to take on, or a delayed closing that put his financing arrangements at risk of expiring and needing to be renewed, often at a less favourable rate.

There was also a question of what Dewi had known, and when. If the tenancy had existed at the time the listing represented the property as vacant, that representation may not have been accurate, and the remedies available to Dilshan, including a price adjustment or a right to delay closing without penalty, depended on establishing that clearly rather than assuming good faith on either side. It was possible Dewi genuinely had not realized the significance of an occupant who had, for instance, moved in informally as a favour to a relative and never signed anything in writing; it was also possible the omission had been more deliberate. Either explanation led to the same practical question, which was what evidence existed about the tenancy's actual start date and terms, and getting that evidence quickly mattered more at this stage than assigning motive.

What we did

  1. Requested full details of the tenancy immediately. We contacted the seller's lawyer the same day to ask when the tenant had moved in, whether there was a written lease, and what notice, if any, had already been given, since the entire strategy depended on these facts rather than assumptions.
  2. Confirmed the tenancy predated the listing. The tenant had in fact been in the unit on a month-to-month basis for several months before the property was ever listed, which meant the vacant-possession representation in the listing was inaccurate at the time it was made, not simply overtaken by a later event.
  3. Advised Dilshan of his legal position clearly. We explained that the tenancy would bind him automatically if it was not properly ended before closing, and that he had grounds to require either a genuinely vacant property on the agreed terms or a renegotiation, rather than closing and discovering a tenant on his first day of ownership.
  4. Pressed the seller to begin the proper notice process at once. Time was central, so we did not wait for a negotiated resolution before insisting Dewi begin whatever notice process was legally required to end the tenancy, to avoid losing additional weeks while the two sides talked.
  5. Navigated a mid-file bereavement delay. Roughly a week into this process, Dewi's mother passed away, and Dewi was unreachable for over a week arranging travel and family matters. We adjusted our approach, communicating primarily through her lawyer, and agreed to a short, defined extension of the closing date rather than pressing an already grieving seller on an unrealistic timeline.
  6. Negotiated a closing date adjustment with financial terms attached. Once Dewi returned, we negotiated a revised closing date that gave enough time for the tenancy to be properly ended, along with a modest credit to Dilshan reflecting the delay's effect on his mortgage rate hold and renovation schedule.
  7. Confirmed vacant possession before releasing funds. We required written confirmation from the seller's lawyer, and a final walkthrough by Dilshan himself, that the unit was genuinely vacant before authorizing the closing to proceed, rather than relying on the seller's assurance alone a second time. This last check mattered because the first assurance of vacancy, at listing, had turned out to be wrong, and releasing mortgage funds on a repeat of that same mistake would have left Dilshan with no practical recourse once the money had already moved.

The outcome

The property closed vacant, exactly as originally promised, though roughly five weeks later than the original date. The seller completed a proper notice process with the tenant, who accepted a move-out arrangement, and the unit was confirmed empty before Dilshan's funds were released. He did not end up as an unwilling landlord to a tenant he had never agreed to take on, which had been the outcome he most wanted to avoid.

The delay was not free. Dilshan's mortgage rate hold expired during the extension and had to be renewed at a slightly higher rate, and his renovation contractor's schedule shifted back by more than a month. The credit negotiated as part of the closing adjustment offset part of that cost, though not all of it, and Dilshan absorbed the rest as the price of getting a clean, lawful result rather than a faster but riskier one.

Ishara, watching the numbers from the mortgage broker side of the file, said afterward that the outcome was the one they had hoped for from the first phone call, even though the path there was longer and harder than either of them expected, complicated as it was by a family loss on the other side that neither side had any way to plan around. Dilshan closed on the property he thought he was buying, with the vacant possession he had been promised from the start.

He started the renovation work about six weeks later than his original plan, which pushed his first rental listing into a different season than he had budgeted for, though the eventual rent he secured was close to what he had originally projected. Looking back on it, Dilshan has said the hardest part was not the legal uncertainty so much as sitting with it for those first few days, not knowing whether the property he had planned around for months was actually going to be his on the terms he had agreed to.

What you can learn from this

  • A residential tenancy in Ontario binds a new owner automatically on closing; it does not need to be registered anywhere, and a contract promise of vacant possession does not override a tenant's existing legal right to remain.
  • If a listing represents a property as vacant, confirm that independently rather than relying on the representation alone, especially close to closing, since an undisclosed tenancy can surface at the worst possible moment.
  • Ending a tenancy properly takes real time and a defined process; if a closing date depends on a tenant moving out, build in enough time for that process rather than assuming it will happen on the contract's original schedule.
  • A delay caused by a genuine personal emergency on the other side is not the same as a delay caused by bad faith; adjusting your approach and timeline to it, without abandoning your legal position, usually serves you better than escalating.
  • When a closing is delayed through no fault of your own, ask for a specific financial adjustment tied to the real costs, like a rate hold expiry or contractor rescheduling, rather than absorbing those costs silently to keep the deal moving.
