Key takeaways
  • Closing on a new condo usually involves more than the price, and your own purchase agreement sets out which extra charges apply to you.
  • During interim occupancy you pay an interim occupancy fee whether or not you move in.
  • Deposits must generally be held in trust, and Tarion deposit protection may help if a builder does not refund one.

You signed a pre-construction agreement years ago, and closing is getting closer. The price you remember is rarely the only amount you will need, and the extra charges can be a surprise if you have not planned for them.

This article explains how to think about those charges in Ontario, covers the costs tied to interim occupancy, deposits and delays, and lists what to ask your lawyer before closing. Items such as HST, development levies and utility connection fees depend heavily on your agreement, so they are worth confirming with your lawyer or accountant.

Why the closing number is more than the price

On a new condo, the amount due at closing is usually the balance of the price adjusted up or down for several items. Common examples buyers ask about are HST, development levies and utility connection or meter fees. Whether each one applies to you, who pays it and how it is calculated depends on the wording of your purchase agreement and on your own circumstances.

Because those items vary so much, do not rely on a general figure from a friend or a website. Ask for a written statement of adjustments from the builder's lawyer, and have your own lawyer or accountant explain each line before you close.

Interim occupancy: paying before the building is registered

Many buyers move in before the condo corporation exists. During interim occupancy you pay an interim occupancy fee whether or not you actually move in.

That fee cannot exceed the total of three things: monthly interest on the unpaid balance at the prescribed rate, estimated monthly municipal taxes, and projected common expenses for the unit.

Once the corporation is running, you will pay monthly common expense fees. These cover maintaining the common elements, reserve fund contributions, and services such as cleaning, building maintenance and condo management. Your share is a percentage set in the declaration and may vary with unit size.

Your deposits and what protects them

Money a condo builder receives, including deposits, must generally be held in trust under the Condominium Act. If a builder terminates the agreement, it must return your deposit in full within 10 days.

If a builder does not refund a deposit, Tarion's deposit protection covers up to $20,000 plus a limited amount of accrued interest.

Delays can add costs of their own

The Statement of Critical Dates in the Tarion Addendum sets your occupancy dates. If occupancy is delayed, compensation is capped at $7,500 in total. It includes a flat $150 a day for living expenses with no receipts needed, plus other costs such as moving and storage, which need receipts.

If the builder gives less than 10 days' notice of an occupancy delay, you receive $1,500. If the unit is not ready by the Outside Occupancy Date, you have 30 days to terminate and are then entitled to a full refund of all money paid plus interest. Check the Statement of Critical Dates in the Addendum attached to your own agreement, because it sets your occupancy dates, and any condition allowing the builder to cancel must be one listed in Schedule A of the Addendum.

What to do next

Frequently asked questions

Is HST always extra on a new condo?

It depends on your agreement and your circumstances, such as whether the price includes it and whether any rebate applies. Ask your lawyer or accountant to confirm how it is treated in your deal.

Do I pay condo fees before I own the unit outright?

During interim occupancy you pay an interim occupancy fee, whether or not you move in.

Will I get my deposit back if the project is cancelled?

Buyers are generally entitled to the deposit back plus accrued interest at two per cent below the Bank of Canada bank rate. Where no units were sold before January 1, 2023 and the developer terminates the agreement, interest is paid at the Bank of Canada policy interest rate instead, while the rate of two per cent below still applies if you rescind during the cooling-off period or after a material change.

What if the builder does not refund my deposit?

Tarion's deposit protection covers up to $20,000 plus a limited amount of accrued interest. You call Tarion at 1-877-982-7466 for a Deposit Refund Claim Form and submit it with your purchase agreement and cancelled deposit cheques.
