The short answer

A dock or boathouse condition in Ontario gives the buyer a window to confirm, at their own expense, that the structure passing to them on closing actually received the approvals it needed and is not exposed to removal by a third party. The clause is DOCKS-1. Its sibling, DOCKS-2, does something different: it is a knowledge-qualified seller warranty that survives closing and speaks to the state of things at completion. The distinction is the whole decision. A condition lets your buyer leave before closing. A warranty gives them a lawsuit afterwards. Most agents pick one out of habit. On a waterfront file where the structure may sit on land the seller does not own, that habit is expensive.

The structure your buyer thinks they bought

A waterfront buyer is not paying for the house. They are paying for the water, and the water is delivered by a dock, a crib, a boathouse or a marine rail. That structure is often the single most valuable improvement on the property and it is frequently the least documented thing in the file.

Three things can go wrong after closing, and all three are survivable if you caught them before. The structure sits partly or wholly on land the seller never owned — a shore road allowance, or bed of the lake the province controls. The structure was built without an approval that was required at the time, or was altered later without one. Or an authority has a live file on it and the buyer’s first letter from the conservation authority arrives in year two.

None of that is exotic on a Muskoka, Kawartha or Rideau file. It is routine, and it is why this category exists.

DOCKS-1 and DOCKS-2 are not variants of the same idea

DOCKS-1 (Condition – Docks/Boathouses (Including Reference to Conservation and/or Canal Authorities)) is a condition. It makes the agreement conditional on the buyer determining, at the buyer’s cost, that the named structure — you fill in whether it is a boathouse, a dock, a pier — received the approvals and permits it needed from the provincial natural resources ministry, from the federal government under the navigable waters legislation, from the conservation or canal authority you name in the blank, and from any other relevant authority. It also asks the buyer to satisfy themselves that the structure is not subject to removal by third parties. Like the rest of this family, it requires the buyer to deliver positive written notice that the condition has been fulfilled. No notice, no deal, deposit back.

DOCKS-2 (Docks/Boathouses – Warranty (Including Reference to Conservation and/or Canal Authorities)) is a representation and warranty from the seller, qualified by their knowledge and belief, that those approvals were obtained. It is expressed to survive closing rather than merge, and it is tied to the circumstances existing at completion.

Read those two descriptions again and notice what the warranty does not do. It does not address removal risk. It does not verify anything. It shifts a liability that only becomes useful once your buyer has closed, paid, and hired a lawyer. Get the actual clauses from your own OREA member copy and put them side by side before you decide which one belongs in your schedule.

The short version

DOCKS-1 buys information before closing. DOCKS-2 buys a claim after closing. On a structure that might have to come out of the water, the information is worth more than the claim — and on most files you want both, not one.

	DOCKS-1	DOCKS-2
Type	Condition, buyer’s benefit	Seller representation and warranty
Who does the work	The buyer, at the buyer’s expense	Nobody — the seller states what they believe
Covers removal by third parties	Yes, expressly	No
Standard applied	Whatever the buyer’s searches turn up	The seller’s knowledge and belief
When it helps	Before closing — the buyer can leave	After closing — the buyer can sue
Survives closing	No, it is spent when fulfilled or waived	Expressed to survive and not merge, tied to the state of things at completion
What it costs your buyer	Search fees, time, possibly a marine or survey opinion	Nothing up front, everything later

Who actually has to be asked

The clause names authorities because there is no single one. Depending on the water body you may be dealing with the provincial ministry responsible for natural resources and forestry, the federal navigable waters regime, a conservation authority, a canal or waterway authority — Parks Canada administers the Trent-Severn and the Rideau, and a structure on those systems lives under a permitting regime a lot of GTA agents have never encountered — plus the municipality for the land-side portion and anything with a roof.

Do not write the clause and leave the authority blank because you are not sure which one applies. The blank is there because the drafter cannot know your water body. Find out before the offer goes in. One call to the municipality’s building department will usually tell you which conservation authority has jurisdiction, and the waterway is obvious from the address.

The land question is separate and it is the one that surprises people. Many older Ontario waterfront properties have an original shore road allowance between the patented lot and the water, and whether it was ever closed and conveyed is a title question, not a permit question. If the dock is on the allowance and the allowance was never conveyed, the approvals conversation is a sideshow. That is a survey and title issue — pair this condition with the shore road allowance clauses and, where the frontage is the access route, with ACC-2 (Condition – Road Access by Open Public Road).

The date you write is almost always too short

Five business days is the reflex and it is wrong here. File searches with an authority are made by written request. Records for a structure built in the 1960s may be on paper, in a basement, in a different office. A conservation authority may need a site visit. Parks Canada has its own turnaround. A surveyor who can tell you where the structure sits relative to the water’s edge and the allowance is not available on Thursday afternoon in July.

Ask each authority the same three questions before you pick a number: how do you accept the request, what is your current turnaround, and what will the response actually tell me. That last one matters, because a response that says “no records located” is not the same as “no approval was required,” and your buyer needs to understand the difference before they decide whether to waive.

NO RECORD IS NOT THE SAME AS NO PROBLEMAn authority that cannot find a file has told you about its filing system, not about the structure. If the buyer is going to close on the strength of a nil search, that is a decision they should be making with their lawyer, in writing, with the search result attached. Do not let it be a decision they make on a phone call with you at 8 p.m. on the deadline.

What the word “knowledge” does to a warranty

Every knowledge-qualified warranty invites the same two arguments: what did the seller actually know, and when were they required to know it. Both are harder than they look.

Coppendale v. Mills, 2025 ONSC 5192, is the case I point agents to, and as reported the facts are unhappy. The buyers had waived their inspection condition. Before closing they found moisture in the basement. They refused to close, taking the position that a warranty given to the best of the seller’s knowledge had been breached. The court read that warranty as speaking to the seller’s knowledge at the time of signing rather than at closing. The buyers forfeited a $20,000 deposit and were ordered to pay $206,703.56 in damages.

Apply that to a boathouse. DOCKS-2 is drafted with an express temporal reach — it survives closing but applies to the circumstances at completion. That drafting choice is not decoration, and if you swap in your own wording or edit the tail of the clause because it read awkwardly, you may have moved the date the warranty speaks to without realising it. That is not an agent’s decision. It is a lawyer’s.

Do not casually edit a survival clause

The words that say when a warranty speaks, and whether it survives closing, are the words that decide the case. If a client wants a warranty reshaped, that request goes to their lawyer before the offer is signed, not after the buyer finds a problem.

Notice, service, and the ordinary way these fail

Waterfront conditions fail on procedure more often than on substance, and the reason is geography. The seller is in Toronto, the agent is at the cottage, the fax number on the agreement has not worked since 2019, and the notice goes to whatever email somebody has in their phone.

High Tower Homes Corp. v. Stevens, 2014 ONCA 911, as reported, involved a waiver sent by fax where the agreement required personal delivery, and it was held ineffective. The notice provision in the agreement governs. Read it before you serve anything, and confirm the addresses on the executed agreement rather than the ones in your contacts.

The other side of the coin is VanderMolen Homes Inc. v. Mani, 2025 ONCA 45, where as reported buyers who had waived and paid were held to the agreement despite a late acceptance of an extension, because the subsequent conduct of the parties kept the agreement alive. A missed technical deadline does not automatically end a deal. It just moves the outcome into a courtroom, which is not where you want your buyer’s cottage to be decided.

Your exposure as the registrant

I have never seen an agent get into trouble over the permit itself. I have seen plenty get into trouble over the listing.

Marketing words you cannot support. “Grandfathered,” “legal boathouse,” “permitted two-slip.” Under the advertising rules 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. If the seller told you it was grandfathered and you put it in the listing, it became your statement.
Repeating the seller without asking for paper. If the seller says approvals exist, ask to see them and put copies in the file. If they do not exist, that is a conversation to have with the seller and their lawyer before the property goes live.
A known problem you carried forward. RECO’s guidance on seller disclosure is that patent defects need not be disclosed and caveat emptor applies, but active concealment removes that protection, and latent defects that render a property unfit for habitation or dangerous must be disclosed. Where a seller’s agent knows of such a fact they must disclose it to every interested buyer, use best efforts to obtain an acknowledgement from each, and give each a copy. A structural failure in a boathouse people stand on is not a filing question.
Advising the other side. Waterfront deals attract self-represented sellers — the family cottage, the estate, the neighbour. Under TRESA you confirm they intend to proceed unrepresented, deliver and explain the RECO Information Guide and the self-represented party form, state plainly that you act for your client and not for them, and make reasonable efforts to obtain written acknowledgement. You must not advise them on price, terms or clauses. Explaining what DOCKS-2 exposes them to is advising them on a clause.
Filling in the authority blank by guessing. If you name the wrong conservation authority in the clause, you have created a condition pointed at an organisation with no jurisdiction. Confirm it.

How I run a waterfront file

The sequence below is not sophisticated. It is just done in order, before the offer, rather than in a panic on day four of a five-day condition.

Identify every structure that touches the water and write down what each one is, in the words the clause blank expects.
Confirm which authorities have jurisdiction — municipality, conservation authority, waterway authority — by calling, not by assuming.
Ask each one how a records request is made and what the turnaround is, then set the condition date against the longest answer with room left over.
Order a survey opinion or a title review on where the structures sit relative to the water’s edge and any shore road allowance, and treat that as a separate track from approvals.
Decide with the client whether you want DOCKS-1, DOCKS-2 or both, and have their lawyer look at any edit to the survival wording.
Serve notice exactly the way the agreement’s notice provision requires, and keep proof in the file.

If the structure is the reason your buyer is buying, the condition period is not overhead. It is the only chance anyone gets to find out what they are actually purchasing. The rest of the clause library is indexed on the articles page if you want the adjacent categories.

Questions agents actually ask

Should I use the dock condition or the dock warranty?

On most waterfront files, both. DOCKS-1 gives the buyer a window to verify approvals and removal risk before closing, at the buyer’s expense. DOCKS-2 is a knowledge-qualified seller warranty that survives closing. The condition is what lets your buyer leave; the warranty only helps once they have already closed and are hiring a lawyer. Using the warranty alone means nobody ever checked.

Which authorities does a dock or boathouse condition in Ontario cover?

The clause contemplates the provincial natural resources ministry, the federal navigable waters regime, a conservation authority or canal authority named in the blank, and any other relevant authority. Which ones actually apply depends on the water body. On the Trent-Severn or the Rideau you will be dealing with Parks Canada. Confirm jurisdiction with the municipality before you fill in the blank.

How long should a dock condition run?

Longer than the five business days people reflexively use. Records requests to an authority are written, older files may be on paper in another office, a conservation authority may want a site visit, and a surveyor is not available on demand in summer. Ask each authority for its current turnaround and set the date against the longest answer, with room.

What if the search comes back with no records for the boathouse?

That tells you about the authority’s records, not about the structure. A nil search is not confirmation that no approval was required. Whether to close on that basis is a decision for the buyer with their lawyer, documented in writing with the search attached. It is not a decision to make verbally with the agent on the last afternoon of the condition.

Does a dock warranty survive closing in Ontario?

DOCKS-2 is expressed to survive and not merge on completion, and to apply to the circumstances existing at completion. Whether any particular warranty survives, and what it covers, turns on the exact wording — which is why editing the tail of a warranty clause is a lawyer’s job. Coppendale v. Mills, 2025 ONSC 5192 shows how much can turn on the date a knowledge-qualified warranty speaks to.

Can I say a boathouse is grandfathered in the listing?

Not unless you can support it, and a seller telling you so is not support. Under the advertising rules a misleading statement is one that causes someone to have a wrong idea or impression, and it does not matter that not everyone is misled. Once you put it in the listing it is your statement, not the seller’s. Ask for the paperwork and keep a copy.

Writing waterfront offers without a second reader?

Cottage and waterfront files carry risks that never appear on a city deal — allowances, authorities, structures in the water. Every agreement my agents write gets reviewed before it goes out, and waterfront schedules get the closest read of all. If that is not happening where you are, let’s talk.
