The situation
The deadline to accept the seller's offer was two business days away when Jamal called. He had closed on a one-bedroom condo in Barrie six weeks earlier, priced in the low 400,000s, and had planned to move in as soon as the existing occupant left. Instead he found a tenant with a signed lease, a rent well under what the unit could fetch on the open market, and a term that ran another fourteen months. The seller's lawyer had sent a short letter offering a modest goodwill credit and a two-day window to accept it before the offer expired.
Jamal worked as an administrative assistant at a Barrie accounting firm, and he had bought the condo as his first home, stretching to make the numbers work on a modest income with a small down payment from savings and a gift from his mother, Nasrin, a bookkeeper who had helped him build the spreadsheet he used to convince himself he could afford the purchase. He had budgeted carefully around the assumption that he would move in on closing day, giving notice on his rental apartment six weeks out and arranging movers for the following weekend. The agreement of purchase and sale he had signed contained a standard clause requiring the seller to disclose any tenancies affecting the unit and to deliver it vacant unless otherwise agreed. No lease had been disclosed before closing. Jamal's position, as he described it to us on the phone, was that he had never heard of any tenant until the keys did not work the way he expected and he found someone already living there with furniture, a lease taped to the fridge, and no intention of leaving.
The tenant, it turned out, was Eitan, described in the lease as a relative of the seller. The rent on the lease was roughly forty percent below what comparable units in the building were renting for, and the lease had been signed only a few months before the sale closed, with a term running fourteen more months from the date Jamal took title. On paper, this looked like a straightforward non-disclosure case: a seller who let a family member stay cheaply and never told the incoming buyer, leaving Jamal stuck paying a mortgage on a unit generating a fraction of its rental value while he continued to rent his own apartment month to month.
The complication came from Jamal's own inbox. Before we could send a demand letter making the strongest version of that argument, we asked him to forward everything he had relating to the purchase, a step we take as routine rather than because we suspect a problem. Among the messages was an email exchange from before closing, between Jamal and his real estate agent, in which Jamal asked whether 'the guy renting the unit' would be a problem for financing. The email was dated five weeks before closing, well before the deal became firm on financing conditions, and it sat quietly in a forwarded thread Jamal had genuinely forgotten he had sent.
The risk we had to size
An unregistered residential lease can still bind a buyer in Ontario. When a landlord sells a rented unit, the sale does not automatically end the tenancy, and a new owner who takes the property subject to an existing lease generally has to honour it until it ends or is properly terminated under the rules that govern residential tenancies. That protection exists for tenants, and it does not turn off just because the buyer says they did not know about the lease. Jamal's frustration that the lease was never registered anywhere, and that a title search would not have revealed it, was understandable but beside the point: leases do not need to be registered against title to bind a new owner who takes the property subject to them.
The strength of a non-disclosure claim against the seller, though, depends heavily on what the buyer actually knew and when. If Jamal had genuinely learned about the tenant only after closing, his case for a credit or damages against the seller was strong: the agreement promised vacant possession, the seller breached it, and Jamal's remedy was a price adjustment or the cost of buying out the lease early, whichever better reflected his actual loss. But the email changed the picture. It suggested Jamal had at least some awareness of a tenant weeks before closing and had not raised it as a closing condition, a reason to delay, or even a passing concern to his own lawyer at the time.
We had to size two risks at once. First, if the seller's lawyer discovered that email, whether through the buyer's agent, through the seller's own knowledge of Eitan's tenancy, or through disclosure in a later dispute, Jamal's credibility on the central fact of the case would be damaged, and a claim that started as a clean disclosure breach could turn into a messier dispute about what he knew and chose not to act on before closing. Second, the two-day deadline meant there was no time to build a fuller record, track down the agent for more context on the exchange, or test how a court might eventually weigh the email against Jamal's broader account, before deciding whether to accept the seller's offer or push for more.
We were direct with Jamal about what the email meant, because softening it would only have set him up for a worse outcome later. It did not eliminate his claim. Knowing someone was 'renting the unit' is not the same as knowing the rent was below market, that the tenant was the seller's relative, or that the lease would survive the sale for another fourteen months. But it weakened his position enough that we could not responsibly advise him to reject a real offer in favour of a fight where his own documents would very likely be used against him if it escalated.
What we did
- Pulled every document in Jamal's file, not just the ones he thought were relevant. Before drafting a single letter, we asked for his full email history with the agent, the lender, and the seller's side going back to the day he first viewed the unit, because a case built on an incomplete file is a case that can be undone by whatever the other side finds later, often at the worst possible moment.
- Identified the email that contradicted his stated timeline. Once we saw the exchange about 'the guy renting the unit,' sent five weeks before closing, we flagged it immediately rather than letting Jamal build expectations around a version of events his own records did not fully support, and we asked him directly whether there was anything else in his history with the property he had not mentioned.
- Had a direct conversation with Jamal about what the email could mean for his claim. He needed to understand, before the two-day deadline expired, that overstating what he did not know would be worse for him than accepting a fair but smaller settlement, so he could weigh the real risk and make an informed choice instead of an emotional one made under time pressure and frustration.
- Reviewed the lease terms against the agreement of purchase and sale. The lease term, rent, and relationship between the tenant and seller all mattered to valuing the loss, since a below-market lease running fourteen months longer represented a real and calculable shortfall in rental income Jamal could have earned had the unit come to him vacant as the agreement promised.
- Calculated a realistic range for the credit, based on the rent gap over the remaining lease term. We estimated the difference between market rent for comparable units in the building and the rent set out in Eitan's lease, multiplied by the fourteen months remaining, to give Jamal a defensible number to negotiate from rather than an arbitrary demand that could be picked apart.
- Countered the seller's initial offer within the deadline, while flagging our own client's exposure honestly. We did not pretend the email did not exist; instead we used its existence to justify accepting a fair number quickly rather than escalating into a longer dispute where the seller's disclosure obligations and Jamal's own knowledge would both come under scrutiny from the other side.
- Negotiated a revised credit before the seller's deadline expired. The seller's lawyer increased the initial offer once we presented the rent-gap calculation clearly and explained how we had arrived at it, and we pressed for the improved number in writing well before the narrow window closed, so Jamal never had to decide anything at the last minute under pressure or guess whether the seller would hold firm.
- Documented the settlement in writing with a full release. We put the agreed credit, the payment timeline, and a mutual release into a signed document, because a verbal understanding or an informal email exchange would have left Jamal exposed if the seller later changed position, and the release gave both sides a clean, final end to a matter that could otherwise have lingered for the rest of Eitan's tenancy.
The outcome
Jamal accepted a credit from the seller in the low five figures, roughly double the seller's opening offer but well short of what a full claim for the entire remaining lease term might have been worth if his knowledge of the tenant had never come into question. The credit was paid within two weeks of the settlement, and Jamal used it to help cover the shortfall between what he was collecting in rent from Eitan and what he had budgeted to receive from the unit once vacant, along with a portion toward the continuing cost of renting his own apartment while he waited out the lease term.
This was not a case where the client walked away made whole. Jamal lost the ability to move into the unit himself for over a year, kept paying rent on his apartment alongside his new mortgage, and accepted less than the theoretical value of his claim because pushing harder risked a fight in which his own email would have been used to argue he had waived his right to complain or, worse, that he had known enough to negotiate the purchase price down before closing and simply failed to. Acting quickly and honestly, rather than overstating what he did not know, kept the loss contained to a number he could absorb rather than a drawn-out dispute with an uncertain result.
Jamal later told us the hardest part was not the money but realizing that a casual question to his agent, sent without much thought five weeks before closing, had shaped the whole negotiation months later. He has since kept a habit of documenting concerns in writing as they arise, and treating his own file, emails included, as something that will eventually be read by someone on the other side of a dispute, whether or not he expects one at the time he writes it.
What you can learn from this
- Assume every email, text, and note you send during a purchase could later be read by the other side, and write accordingly.
- An unregistered lease can still bind a new owner in Ontario; vacant possession promised in an agreement is not automatically delivered.
- If you suspect a problem before closing, raise it in writing as a condition or concern, not as a casual aside to your agent.
- Your own records can undercut a strong legal claim faster than anything the other side produces; review your file honestly before you demand anything.
- A quick, realistic settlement built on a clear calculation often protects you better than a larger claim that depends on facts you cannot fully control.
