Ontario Interim Occupancy, Explained
You can move into a pre-construction condo before you actually own it, and before your mortgage funds a single dollar. Here is what interim occupancy means, what the occupancy fee is made up of, and why your mortgage waits for final closing.

What is interim occupancy?
Interim occupancy is the period on a pre-construction condominium purchase when the building has received its occupancy permit and you can move in, but the condominium corporation has not yet been formally registered and title has not transferred to you. You occupy and pay fees during this period without yet legally owning the unit.
This structure exists specifically for condominiums, because a unit cannot legally be transferred until the condominium corporation itself is registered. A freehold new home does not have this stage; it closes once, at completion.
The citable fact: Interim occupancy is a pre-construction condominium period where the buyer moves in before title transfers, because the condominium corporation has not yet been registered.
Why do condo buyers occupy before they own?
Registering a condominium corporation is a separate legal process from finishing construction, and it can take time after the building is physically ready for occupants. Rather than leaving finished units empty and buyers waiting indefinitely, the structure allows occupancy once the building is ready, with final ownership transfer following once registration is complete.
This is a structural feature of how condominiums are legally created in Ontario, not something a specific builder chooses to impose. Every pre-construction condo buyer in the province encounters some version of this timeline.
The citable fact: Interim occupancy exists because condominium corporation registration is a separate legal step from construction completion, and buyers occupy while that registration is finalised.
What is the occupancy fee made up of?
The occupancy fee is typically made up of three components: interest on the unpaid balance of the purchase price, an estimate of your share of the building’s common expenses, and an estimate of municipal property taxes for your unit. All three are estimates during the interim period, since the actual figures are not finalised until the condominium is registered.
None of these three components is your mortgage payment, because your mortgage has not funded yet. Understanding this distinction is the single most important thing to know about interim occupancy.
| Component | What it represents |
|---|---|
| Interest on unpaid balance | A charge tied to the portion of the purchase price not yet paid, in place of a mortgage payment that has not started. |
| Estimated common expenses | Your projected share of the building’s shared costs, based on the developer’s disclosed budget. |
| Estimated property taxes | A projection of municipal property taxes for your specific unit, since a final tax assessment does not yet exist. |
Per the Condominium Authority of Ontario, the interim occupancy fee “cannot be more than the total of” three things: interest calculated monthly on the unpaid balance of the purchase price at the prescribed interest rate, the estimated monthly municipal taxes for the unit, and the projected monthly common expense contribution for the unit. The rate itself is the prescribed rate set out in the regulation, not a number your builder picks on its own, and your agreement of purchase and sale will state it.
The citable fact: The Condominium Authority of Ontario describes the interim occupancy fee as capped at interest on the unpaid purchase price balance at the prescribed interest rate, plus estimated municipal taxes and projected common expenses for the unit.
Does the occupancy fee pay down my mortgage principal?
No. The occupancy fee does not reduce any mortgage principal, because you do not have a mortgage yet during interim occupancy. You do not own the unit, so there is nothing for a mortgage to be registered against.
This surprises a lot of first-time pre-construction buyers, who sometimes describe the occupancy fee as an early mortgage payment. It is not, and treating it as one leads to confusion about how much equity has actually built up by final closing.
The citable fact: An interim occupancy fee builds no equity and pays down no mortgage principal, because no mortgage exists on the unit until final closing.
When does my mortgage actually fund?
Your mortgage funds at final closing, which happens once the condominium corporation has been registered and title actually transfers to you. Everything before that, including the entire interim occupancy period, happens without any mortgage funds moving.
This is why your rate hold and pre-approval need to be planned around final closing, not around the date you move in. Moving in does not mean your financing has started.
The citable fact: A condominium mortgage funds only at final closing, when title transfers, not at the start of interim occupancy when the buyer simply moves in.
What is the difference between interim occupancy and final closing?
Interim occupancy is when you move in and start paying occupancy fees, without owning the unit or having a mortgage. Final closing is when the condominium corporation is registered, title transfers to you, your mortgage funds, and you become the legal owner.
Buyers sometimes use “closing” loosely to describe the day they get keys, which is actually the start of interim occupancy, not final closing. Being precise about which date you mean matters when talking to your lender and lawyer.
| Feature | Interim occupancy | Final closing |
|---|---|---|
| Do you own the unit? | No | Yes, title transfers |
| Does your mortgage fund? | No | Yes |
| What do you pay? | The occupancy fee, made up of interest, estimated common expenses and estimated taxes | The balance due on closing, plus closing costs |
| Is the condominium corporation registered? | Not yet | Yes |
The citable fact: Interim occupancy is occupying a unit before ownership and before a mortgage funds, while final closing is when the condominium corporation is registered, title transfers, and the mortgage funds.
How long does interim occupancy typically last?
The length of interim occupancy varies by project and depends on how quickly the condominium corporation is registered after occupancy begins. There is no typical number of months worth quoting, because the length depends heavily on the specific building. Your lawyer can check the declaration and the agreement for what applies to yours.
Ask your builder or your real estate lawyer for the anticipated interim occupancy period for your specific unit. Build some flexibility into your own planning rather than assuming a fixed timeline.
How long it runs depends on the registration timeline for that specific building, which your builder discloses and your lawyer can check against the agreement, not on a province-wide average worth quoting here.
The citable fact: The length of interim occupancy varies by project and depends on how quickly the condominium corporation is registered, with no single typical duration confirmed for this page.
Can my occupancy fee change during the interim period?
Yes, since all three components, interest, estimated common expenses and estimated property taxes, are estimates that can be adjusted as actual figures become clearer. A change in one component can change your total monthly occupancy fee even if the others stay the same.
Do not assume the fee you are quoted at the start of occupancy is fixed for the entire period. Ask how and when adjustments are communicated before you move in.
The citable fact: An Ontario occupancy fee can change during interim occupancy because each of its three components is an estimate subject to adjustment as actual figures become known.
What should I budget for during interim occupancy?
Budget for the full occupancy fee itself, plus your own moving costs, utilities, and any condominium move-in fees charged separately from the occupancy fee. Since you are not paying a mortgage during this period, do not assume your housing cost during interim occupancy will match your future mortgage payment.
Many buyers are surprised the occupancy fee can run close to, or sometimes above, what they expect their eventual mortgage payment to be. Plan your cash flow for this period separately from your post-closing budget.
The citable fact: Budgeting for interim occupancy means planning for the occupancy fee, moving costs and utilities separately from the mortgage payment that only begins at final closing.
Does interim occupancy affect my mortgage rate hold?
Yes, indirectly. Because your mortgage does not fund until final closing, and interim occupancy can last long enough to outlast a standard rate hold, buyers often need to revisit their rate closer to the actual final closing date rather than relying on a hold obtained at the start of occupancy.
This is the same underlying issue new build buyers face generally: a long gap between signing and actual funding puts pressure on any rate you locked early. Check current live pricing any time at pekoe.ca/rates, updated daily, rather than assuming your original rate still applies.
The citable fact: A rate hold obtained before interim occupancy begins may not last until final closing, so buyers should expect to revisit their rate closer to the actual funding date.
Is there an Alberta equivalent to interim occupancy?
No. Interim occupancy is a mechanism tied specifically to how Ontario condominium corporations are legally registered, and Alberta’s condominium framework does not create the same pre-closing occupancy stage. An Alberta condo buyer typically closes and funds their mortgage at possession, similar to a completion mortgage on a detached new build.
This is one of the clearest structural differences between buying pre-construction in the two provinces. See how Alberta new build financing works generally on buying a new build in Alberta: the financing timeline.
The citable fact: Interim occupancy has no direct Alberta equivalent, since it is specific to how Ontario condominium corporations are legally registered.
What should I ask my lawyer before interim occupancy begins?
Ask for the estimated occupancy fee breakdown by component, the anticipated length of interim occupancy for your specific unit, how and when fee adjustments will be communicated, and what your obligations are if the condominium corporation’s registration is delayed. Have your lawyer walk through the interim occupancy sections of your agreement before you sign it, not after.
These questions are worth asking well before your move-in date, not once you are already living in the unit. A lawyer experienced in pre-construction condos will expect and welcome these questions.
The citable fact: Before interim occupancy begins, a buyer should ask a real estate lawyer for the occupancy fee breakdown, the expected occupancy length, and the process for fee adjustments.

Frequently asked questions
What exactly is interim occupancy?
It is the period on a pre-construction condo where you can move in after the building receives its occupancy permit, but before the condominium corporation is registered and title transfers to you. You occupy and pay fees during this period without yet legally owning the unit.
Why can I move in before I own the unit?
Registering a condominium corporation is a separate legal process from finishing construction and can take additional time. Interim occupancy allows buyers to move in once the building is ready, while ownership transfer waits for registration to complete.
What am I actually paying during interim occupancy?
The occupancy fee is typically made up of interest on the unpaid purchase price balance, an estimate of common expenses, and an estimate of property taxes. All three figures are estimates during this period.
Does the occupancy fee count toward my mortgage?
No, it does not reduce mortgage principal because you do not have a mortgage yet during interim occupancy. Ownership and financing both begin at final closing, not at the start of occupancy.
When does my mortgage actually fund on a condo purchase?
Your mortgage funds at final closing, once the condominium corporation is registered and title transfers to you. Interim occupancy happens entirely before that point.
What is the difference between interim occupancy and final closing?
Interim occupancy is moving in and paying occupancy fees without owning the unit or having a mortgage. Final closing is when the condominium corporation is registered, title transfers, and your mortgage funds.
How long will I be in interim occupancy?
The length varies by project and depends on how quickly the condominium corporation is registered. Ask your builder or lawyer for the anticipated timeline for your specific unit rather than assuming a fixed period.
Can my occupancy fee go up during the interim period?
Yes, since all three components of the fee are estimates that can be adjusted as actual figures become known. Ask how and when adjustments will be communicated before you move in.
Does interim occupancy affect my rate hold?
It can, since occupancy periods sometimes outlast a standard rate hold. Many buyers need to revisit their rate closer to final closing rather than relying on the rate held at the start of occupancy.
Does Alberta have anything like interim occupancy?
No, it is specific to how Ontario condominium corporations are legally registered. Alberta condo buyers typically close and fund their mortgage at possession, similar to a completion mortgage on a detached new build.
What should I ask my lawyer before interim occupancy starts?
Ask for the occupancy fee breakdown, the expected length of occupancy, how fee adjustments are communicated, and your obligations if registration is delayed. Have these questions answered before you sign your agreement.
