How Ontario Pre-Construction Condo Occupancy Fees Are Calculated

When you take possession of a new Ontario condo before the building is registered, you enter the interim occupancy phase. During this time, you do not yet own the unit in the legal sense — the condo corporation has not been created, and your mortgage has not been advanced. Instead, you pay the builder a monthly occupancy fee.

For many buyers, the occupancy fee is confusing because it looks like rent but is not. This article walks through the three statutory components of the occupancy fee, how they are calculated, what the practical dollar impact looks like (in general terms), and what to review in your own agreement.

The legal basis for the occupancy fee

The Condominium Act specifies the components of the occupancy fee that a builder can charge during interim occupancy. The formula is statutory — not arbitrary. Builders cannot charge more than the Act permits (though they can charge less if the agreement is more favourable to the buyer).

As of writing, confirm the current formula with your lawyer, since regulations under the Act can change.

The three components of the occupancy fee

Component 1: Interest on the unpaid purchase price

The first component is calculated as interest on the amount you have not yet paid to the builder — that is, the purchase price minus the deposits you have already paid.

Formula: (Purchase Price − Total Deposits Paid) × Prescribed Rate ÷ 12

The "prescribed rate" is set by regulation under the Condominium Act and is not the same as a mortgage rate from your bank. As of writing, verify the current prescribed rate with your lawyer or the HCRA. The rate is reviewed and can change.

Example in general terms: If your purchase price is $600,000 and you have paid $90,000 in deposits, the unpaid balance is $510,000. The interest component of your occupancy fee is based on that balance at the prescribed rate, divided by 12 for the monthly amount.

Component 2: An amount equal to estimated property taxes

The second component is an estimate of the monthly realty taxes for your specific unit. Since the condo has not yet been assessed as an individual property by the Municipal Property Assessment Corporation (MPAC), the builder uses an estimate.

This estimate is based on:

• The anticipated assessed value of the unit
• The municipal tax rate in effect

At final closing, the actual tax account is established and any over- or under-payment during occupancy may be adjusted on your statement of adjustments.

Component 3: A contribution to common expenses

The third component is your unit's share of the building's projected monthly common expenses (maintenance fees). This is the same figure that will appear in your maintenance fee budget when the condo is registered, prorated for your unit.

During the occupancy phase, the condominium corporation has not yet taken over the building. The builder is effectively running the common elements and collecting contributions from early occupants to cover those costs.

How the total occupancy fee compares to your eventual mortgage payment

Many buyers are surprised to find that the occupancy fee is lower than their anticipated mortgage payment. There are two reasons for this:

1. The interest-on-balance component uses the prescribed Act rate (which may be lower than market mortgage rates, depending on conditions as of writing).
2. There is no principal repayment in the occupancy fee — you are paying pure interest on the unpaid balance, plus taxes and maintenance, not reducing your debt.

This means that while the occupancy fee may seem manageable, the equity-building part of your investment does not begin until final closing, when your mortgage kicks in.

What to look for in your agreement

Is the rate fixed or variable?

The prescribed rate under the Act is reviewed periodically. Your agreement should specify whether the rate used for the interest component is fixed for the entire occupancy period or recalculated at each renewal of the occupancy period.

How long will the occupancy period last?

The agreement should specify an expected occupancy date and an outside ("critical") date. A longer occupancy period means more months of paying occupancy fees without building equity or making mortgage payments.

Is there a reconciliation at final closing?

Some agreements include a provision to reconcile occupancy fee payments against any deposit interest the builder owes. Understand whether this applies in your case.

Does the agreement correctly reflect your deposit amounts?

The occupancy fee calculation requires the builder to subtract all deposits actually paid. Confirm that the agreement accurately tracks the timing and amounts of each deposit payment so the fee is correctly computed.

Strategies for managing occupancy fee costs

• Make the largest deposit you can earlier in the process — a larger upfront deposit reduces the unpaid balance that attracts interest under component 1.
• Ask your lawyer to estimate the occupancy fee at the time you review the agreement — this is a calculation your lawyer can do based on the purchase price, deposit schedule, prescribed rate, and projected maintenance fees.
• Budget separately for the occupancy period — your mortgage approval is based on your expected closing costs and monthly payments, but during occupancy you are paying the fee out of pocket without mortgage advances. Confirm your lender understands the timeline.
