Survey Clause Ontario Real Estate: Existing, New and Declarations

Title insurance did not make surveys irrelevant. It made them invisible.

Twenty-five years ago a survey was standard on a residential file. Then title insurance became the default, lawyers stopped requiring surveys on most transactions, and a generation of agents arrived having never seen one.

What changed is who absorbs certain risks after closing, which is a legal question I am not going to resolve. What did not change is the set of facts a survey tells you that nothing else does: where the boundary is, whether the fence sits on it, whether the addition is inside the setbacks, and where the right of way crosses the driveway.

Those facts show up where the buyer intends to do something – build, sever, add a garage, put in a pool, fight about a fence. And they show up when a lender or a lawyer decides, late, that this property needs a survey. Neither moment is a good time to learn that a plan of survey costs real money and takes weeks.

Four clauses, and only one of them is about the buyer

SURVEY-1 is the odd one out and the one residential agents should use most. It records the buyer’s acknowledgement that a new survey may be required for financing and to satisfy their own solicitor, and that the buyer will obtain it at their expense.

Read that as two things at once. It is a cost allocation – the buyer pays – and a written record that the possibility was raised before closing. That second function is why I like it. The complaint six weeks after closing is rarely that the survey was expensive. It is that nobody mentioned one might be needed. A clause answers that in a line.

The other three run the other way. SURVEY-2 (Seller to Provide Existing Survey with Declaration) and SURVEY-3 (Seller to Provide New Survey) are seller delivery obligations at the seller’s expense, by a stated date. SURVEY-4 (Survey, Building Plans, Mechanical Drawings, Warranties) is the commercial version and asks for more than a survey.

An old survey without the declaration is close to useless

Here is the distinction that matters most, and the reason SURVEY-2 exists in the form it does.

A survey is a picture of a property on the day it was made. A 1988 survey tells you where the fence was in 1988. It says nothing about the deck the second owner built, the shed the third owner dragged into the corner, or the fence the neighbour moved. Handed an old survey and nothing else, a buyer has a document that may actively mislead them about the property as it stands.

SURVEY-2 pairs the existing survey with a seller declaration, delivered on completion, in which the seller confirms that nothing has been built or added since the survey was drawn — not to the house, not to the outbuildings, not to the fencing. That declaration is the whole value of the clause. It converts a historical document into a statement about the present, made by the person best placed to know.

These are delivery obligations, not conditions, and that is the trap

A condition has a deadline, a notice mechanism, a stated consequence if notice is not given, and usually a waiver right. SURVEY-2, SURVEY-3 and SURVEY-4 have none of that. They are promises to deliver something by a date. There is no notice to give, no waiver to sign, and no paragraph that says the agreement ends if the survey does not arrive.

Which means that if the seller misses the date, the buyer’s position is a contractual question about breach and remedies – and that is a question for their lawyer, not a self-executing exit. A buyer who assumed that a missing survey meant they could walk away will be disappointed, and the agent who implied it will have a difficult phone call.

So if the survey genuinely matters – the buyer is buying for a project, the property has a visible boundary issue, the lender has signalled a requirement – do not rely on a delivery clause alone. Pair it with a condition that gives the buyer a decision point: a document review condition, a lawyer’s approval condition, or one drafted by counsel. The delivery clause produces the document. The condition is what lets your buyer act on it.

New surveys take longer than your condition period

SURVEY-3 sounds like the clean solution and it is the one that most often blows up a timeline. A new plan of survey is professional work by an Ontario Land Surveyor. It requires field attendance, research against the registered title, drafting and signing. Lead times move with the season and with how busy the local surveyors are, and in the spring and summer they are busy.

Before you write a date into SURVEY-3, have somebody call a surveyor and ask what they are quoting for turnaround right now, in that municipality. Then set the date from the answer with room to spare. Writing a two-week delivery date because two weeks felt reasonable is how you create a breach that nobody wanted.

And take deadlines seriously in both directions. Ontario courts have upheld terminations over remarkably short delays – in 3 Gill Homes Inc. v. 5009796 Ontario Inc. (Kassar Homes), 2024 ONCA 6, as reported, thirty-five minutes. Those are builder agreement cases and I am not suggesting the same result travels to a survey delivery date. The counterweight matters too: in More v. 1362279 Ontario Ltd. (Seiko Homes), 2023 ONCA 527, as reported, a party who was not ready, willing and able could not rely on time being of the essence, and pouncing on trivial delays was treated as unreasonable. Advise accordingly, which mostly means do not tell anybody they are out because a date slipped.

If available is doing a lot of work in SURVEY-4

SURVEY-4 is built for commercial and investment files. The seller pays for a fresh survey from an Ontario Land Surveyor, and that survey has to plot where everything sits today: what is built on the land, what has been added to it, the fencing, the easements and rights of way, and anything crossing a boundary line. The clause then reaches further, picking up building plans, mechanical drawings, other plans, and warranties and service manuals for equipment or chattels included in the price.

Read the qualifier as what it is. Availability is assessed by the person holding the documents. A seller who cannot find the mechanical drawings has not breached anything. If your buyer’s underwriting depends on seeing specific documents, identify them by name in the agreement and think hard about whether a qualified obligation is enough – and if it is not, that is a drafting conversation with the buyer’s lawyer before the offer goes in, not an argument afterwards.

Where surveys still decide files

The residential transactions where I want a survey question asked out loud are the ones with a plan attached to the buyer’s intentions.

• Anything the buyer means to build. Additions, garages, pools and secondary suites run into setbacks and easements, and setbacks are measured from a boundary somebody has to locate.
• Visible boundary oddities. A fence out of line with the neighbours’, a driveway that appears shared, a hedge that has clearly moved, a shed tucked into a corner.
• Rights of way and mutual drives. Common in older urban neighbourhoods, and the source of a particular kind of long-running dispute.
• Waterfront. Shore road allowances and the location of structures near the water are their own subject, and a survey is usually where that conversation starts.
• Severance and development files. If a lot is being divided the survey is not optional, and the timeline is longer than anyone budgets for.

Your exposure: listings, lot sizes and what you should never say

The advertising rules reach this subject more directly than agents expect. Under RECO Bulletin 5.1, a misleading statement is one that causes someone to have a wrong idea or impression, and it does not matter that not everyone was misled. Lot dimensions published in a listing are statements. If they came from a registry product, a municipal record or the last listing rather than from a survey, they may not describe the parcel accurately. Mark approximations as approximate, and never confirm a dimension you have not seen surveyed.

On disclosure, RECO Bulletin 7.4 sets the framework: patent defects need not be disclosed – caveat emptor – but actively concealing one removes that protection, and latent defects rendering a property unfit for habitation or dangerous must be disclosed. A known encroachment is not automatically in that category, and I am not going to characterise it for you. What I will say is that a seller who knows a structure sits over a boundary should be having that conversation with their own lawyer, and a listing agent who knows it should be getting written instructions rather than deciding alone.

Pull the current wording from your own OREA member copy before using any of them. I am describing what each clause does and how they differ; the text is theirs and it moves between revisions.

How I want survey questions handled

1. At the listing appointment, ask whether a survey exists and whether the seller would declare that nothing has been added since it was made.
2. On the buyer side, ask what the buyer intends to do with the property. Build, sever, add or fight about a fence all change the answer.
3. Where no seller survey is coming and the buyer may need one, put SURVEY-1 in the agreement.
4. Where the seller is providing one, choose between SURVEY-2 with a declaration and SURVEY-3, and negotiate the cost openly at offer stage.
5. Before setting a SURVEY-3 date, get a real turnaround from a local surveyor and add room.
6. If the survey could change your buyer’s mind, pair the delivery obligation with a condition that gives them a decision point.
7. Send the survey to the buyer’s lawyer the day it arrives, and do not interpret it for anyone.

Surveys are a small category that decides a disproportionate number of unhappy files, mostly because the document arrives too late to be useful or without the declaration that makes it meaningful. Both are fixed at offer stage with one extra paragraph. The rest of this series is indexed at all articles.

This is professional commentary from a Broker of Record on drafting practice around survey clauses in Ontario agreements of purchase and sale. It is not legal advice. Boundaries, encroachments, easements and the adequacy of any survey or title product are questions for the client’s lawyer and, where the physical facts are in issue, an Ontario Land Surveyor. This is general professional commentary from a Broker of Record on drafting practice. It is not legal advice, it is not a substitute for your own brokerage’s policies, and it does not create any professional relationship.
