When the Landlord Can’t Hand Over the Space on Time: Delayed Possession in Ontario Commercial Leases
The unit is still under construction and the landlord’s Form 510 is on the table. Here is what that form does if handover runs late, and what you can still change before you sign.
If the landlord can’t deliver the premises on the agreed date, can I walk away from an Ontario commercial Agreement to Lease?
Not under the standard form. OREA Form 510 contains no termination right for late delivery and no latest date by which the landlord must hand over the space. What it gives you instead is clause 15: rent abates for the length of the delay, and you agree to accept that abatement in full settlement of all claims arising because the premises were not ready.

I’m Arthur Zhao, a real estate broker in Toronto. Picture the moment before the signature: the landlord’s side has sent over an Agreement to Lease on OREA Form 510, the blanks are mostly filled in, and the unit you want is still bare studs and temporary lighting. Someone has written a commencement date into clause 3. Nobody has said what happens if the construction crew misses it.
That is the question to settle now, while you can still edit the document. The pre-printed form already has an answer for late delivery, and it is a narrow one. I’ll start with what to ask and what you can try to add, then walk through what the form does if you change nothing, and finish with why the law outside the contract will not fill the gap for you.

Before you sign: what to ask the landlord
Clause 11 of Form 510 says the landlord agrees to complete the work described as the “Landlord’s Work” in a Schedule attached to the Agreement. Everything about a late handover hangs off that Schedule, so start there.
What exactly is the Landlord’s Work? If the Schedule letter in clause 11 is blank, or the Schedule just says “base building”, you do not yet know what the landlord has promised to finish. Ask for a written scope: demising walls, washrooms, HVAC, electrical service, storefront, whatever your use under clause 2 needs.
What date is the landlord working to, and what stands between today and that date? Permits, trades, inspections. The form itself does not ask the landlord to disclose any of this; you have to ask.
Who decides the space is ready? Clause 15 turns on whether the premises are “completed by the Landlord for occupancy by the Tenant”. The form does not define that phrase. If you and the landlord picture different things, it is better to find out now.
How will you be told? Clause 10 says any notice under the Agreement must be in writing. Ask how and when the landlord will confirm the handover date.
⚠️Waiting for handover does not mean you can start early. Clause 11 of Form 510 says the tenant shall not proceed with any work within or affecting the premises without the landlord’s prior written approval, which is not to be unreasonably withheld. Sending your own trades in while the landlord’s crew is still working, without that written approval, would be contrary to clause 11.
What you can try to write into the Schedule
Clause 8 lets the parties attach Schedules that form an integral part of the Agreement. OREA’s own clause library has a “Work by Landlord” clause (LEASE/COMM-51) under which the landlord covenants to do listed work before the tenant takes possession, at no cost to the tenant. It names no deadline and no consequence if the work is late. I checked the commercial lease clauses in that library: none of them sets an outside date or gives the tenant a right to terminate for late delivery.
So anything beyond the pre-printed text has to be negotiated. These are options, not rules, and the landlord can say no to any of them:
- An outside date — a latest date for handover, after which you can terminate and recover your deposit.
- A completion standard — what “completed for occupancy” means for this unit, and how it is confirmed.
- Date adjustments — the term commencement and expiry dates in clause 3, and any rent-free fixturing period, move with the actual handover date.
- A per-day amount for delay — a negotiated credit or payment for each day past a stated date.
- Advance written notice of the handover date, so you can schedule your own trades.
Whether any of these is worth asking for depends on how much you are spending before opening and how firm your opening date has to be. That is a business call, and your lawyer should draft the wording.
If nothing is changed: what clause 15 does
Suppose you sign the form as printed. Clause 15, “Occupancy or Rent to Abate”, applies if the premises are not completed by the landlord for occupancy on the date set out for commencement of the Term. That date is the one in clause 3(a).
When that happens, two things follow from the same sentence. The rent under the Agreement abates to the extent of the delay. And the tenant agrees to accept that abatement in full settlement of all claims the tenant might otherwise make because the premises were not ready by that date.
According to OREA’s annotation on its 2026 edition of the form, the clause means that if the landlord has not completed the Landlord’s Work, rent is not to be paid by the tenant and that is to be full settlement of any claims the tenant may have.
Notice what the clause does not say. It does not set a limit on how long the delay can run. It does not give either party a right to end the deal. It does not move the termination date in clause 3(a).
Clause 4: two ways to start the rent
Clauses 14 and 18: the Agreement is the document that counts
Clause 14 says the formal lease shall be prepared by the Landlord, at the landlord’s expense, in accordance with the terms and conditions of the Agreement. It also says the lease is to be signed by both parties before either party starts work on the premises and before the tenant takes occupancy.
Clause 18 does two things that matter here. First, if a provision you add to the Agreement, including in a Schedule, conflicts with the pre-printed text, the added provision supersedes the pre-set one to the extent of the conflict. An outside date or termination right written into a Schedule would therefore override the silence of clause 15. Second, the Agreement and its Schedules are the entire agreement: there is no representation, warranty, collateral agreement or condition other than what is written in it.
Put together: a verbal assurance that the unit “will definitely be ready by spring” is not part of the deal unless it is in the document.
💡 My own view: the Agreement to Lease is the tenant’s last real negotiating window. Once it is signed, the landlord’s side drafts the formal lease under clause 14, and its job is to reflect the Agreement. A point you never put into the Agreement is hard to add later, because you would be asking the landlord to give something new in a document they control. If late delivery would hurt your business, raise it before your signature goes on Form 510, not when the lease draft arrives.
No backstop outside the contract
It is reasonable to wonder whether Ontario law steps in where the form is silent. For commercial premises, the relevant statute is the Commercial Tenancies Act. I searched the current consolidation from Ontario e-Laws: it deals with matters such as re-entry and forfeiture, distress for rent, assignment consent and overholding, and it has no provision on a landlord failing to deliver possession on time.
So for a commercial unit the answer sits in the contract you sign: the printed form, plus whatever you add to it. If what you add is nothing, clause 15 is the whole of your arrangement for a late handover. I can’t tell you how a court would treat a particular delay, and this article does not try to; that is a question for your lawyer, with your documents in front of them.
Before you sign a Form 510 on a unit that isn’t finished
A working list. Items in the middle group are things to negotiate, not things the landlord has to accept.
- ☐Get the full written scope of the Landlord’s Work and confirm which Schedule it will be in.
- ☐Ask what date the landlord is working to and what permits or inspections are still outstanding.
- ☐Ask who decides the premises are “completed for occupancy” and how that will be confirmed.
- ☐Ask how and when you will receive written notice of the handover date.
- ☐Propose an outside date, with a right to terminate and recover your deposit if it passes.
- ☐Propose that the clause 3 term dates, and any fixturing period, move with the actual handover date.
- ☐Decide which clause 4 box you want ticked and make sure only one is.
- ☐Have your lawyer draft the added wording so it clearly overrides the printed text under clause 18.
- ☐Get the landlord’s prior written approval of your Tenant’s Work, as clause 11 requires.
- ☐Confirm the formal lease has been signed by both parties, as clause 14 requires before work or occupancy.
- ☐Compare the landlord’s lease draft line by line against the signed Agreement.
- ☐Book contractors and set an opening date against the confirmed handover date, not the target date.

Frequently Asked Questions
What counts as “completed for occupancy” in a commercial lease?
OREA Form 510 does not define it. Clause 15 uses the phrase “completed by the Landlord for occupancy by the Tenant”, and clause 11 ties the landlord’s obligation to the Landlord’s Work described in a Schedule. If you want a clear test, such as a list of finished items or a sign-off step, it has to be written into that Schedule.
Can I make the landlord send me construction updates while I wait?
Nothing in Form 510 requires progress reports. You can propose a reporting obligation in a Schedule, and clause 8 makes attached Schedules an integral part of the Agreement. Clause 10 already requires notices under the Agreement to be in writing.
Is the rent abatement for a late handover the same as a fixturing period?
No. The clause 15 abatement applies because the landlord has not delivered the premises on the term commencement date. Form 510 has no pre-printed fixturing clause; a rent-free period for your own build-out has to be negotiated and written in, and the Agreement should say whether it starts on the actual handover date.
If handover is late, does my lease end later too?
Not under the printed form. Clause 3(a) sets a fixed commencement date and a fixed termination date, and nothing in Form 510 moves them because the premises were late. If you want the term to shift with the actual handover, it has to be added to the Agreement.
Could a late handover affect my renewal option?
The renewal right in clause 3(b) requires written notice no less than a set number of months before the current term expires, and you must not be in default. The form does not adjust that expiry date for a late start, so if the term dates are not moved, the notice deadline is counted from the original end date.
