Key takeaways
  • Condo builders must list extra charges and expected price adjustments, with dollar values, in Schedule B of the Tarion Addendum.
  • The Tarion Addendum overrides conflicting terms in your agreement, and early-termination conditions it does not allow cannot be enforced.
  • Review every adjustment line by line before closing, and get legal advice if a charge is not in your agreement.

You signed for a pre-construction condo at one price, and now the closing numbers are higher. The builder points to development charges, levies, tax or other adjustments. It is a stressful moment, especially when you have already paid deposits and arranged your mortgage.

Whether you have to pay depends on what your agreement of purchase and sale and its Tarion Addendum actually say. This article explains the usual places to look, the costs that commonly appear, and what you can question.

Start with Schedule B of the Tarion Addendum

Condo builders must list extra charges and expected adjustments to the final price, with dollar values, in Schedule B of the Tarion Addendum. This is the first place to compare against your closing figures. A charge that appears on your statement of adjustments but cannot be found in your agreement deserves a question.

If an adjustment such as development charges could produce rebates, the agreement must say how those rebates will be shared. So if the builder keeps a rebate that came from a charge you paid, check what your agreement says about sharing.

The Tarion Addendum overrides any conflicting terms in the rest of the agreement. That matters when the main agreement contains broad wording that seems to let the builder add whatever it likes.

Charges that commonly show up at closing

Not every higher number is a surprise. Several costs are known to appear on new condo closings, and each has its own rules.

CostWhat to know
Tarion enrolment feeThe vendor pays it, but vendors commonly pass it on to buyers in the statement of adjustments. Not all do.
Development charges and leviesThese must be listed with dollar values in Schedule B if they are expected adjustments.
Interim occupancy feeCapped at monthly interest on the unpaid balance, estimated municipal taxes and projected common expenses. It is not credited to the price.
HSTRebates may reduce it, and the rules change often. Ontario's rebate returns 75% of the provincial part of the HST on a qualifying new home, up to $24,000. First-time buyer rebates and a temporary enhanced rebate for builder purchases from April 1, 2026 to March 31, 2027 may also apply.
Land transfer taxA refund of up to $4,000 is available to eligible first-time buyers.

What you may be able to challenge

Whether an increase is valid depends on your documents, so a lawyer should read them. These are common questions to raise:

Keep in mind the timing. The 10-day cooling-off period to rescind a pre-construction purchase is early in the process, and the agreement does not bind you until you receive both the disclosure statement and Ontario's Residential Condominium Buyers' Guide. By closing, that window is long past, so most price disputes turn on the wording of the agreement instead.

Delays, closing dates and price pressure

Price increases sometimes arrive with a changed closing date. Changing a closing date generally needs at least 90 days' written notice. While the occupancy date is tentative, the builder may extend it several times without paying compensation, but must give 90 days' notice of each extension.

A delay can lead to Tarion delayed-occupancy compensation of up to $7,500 in total, with living expenses paid at a fixed $150 a day and no receipts needed. A builder that fails to give 10 days' notice of an occupancy delay must pay the buyer $1,500. If the unit is not ready by the Outside Occupancy Date, you have 30 days to terminate. Terminating is a major step, so talk to a lawyer first.

What to do next

Whether a particular charge is allowed depends on the exact wording of your documents, so bring everything to a real estate lawyer early.

Frequently asked questions

Can a condo builder add charges after I sign?

Builders must list extra charges and expected adjustments with dollar values in Schedule B of the Tarion Addendum. Charges outside your agreement are worth questioning, and a lawyer can tell you whether they are allowed.

Will I have to pay the Tarion enrolment fee at closing?

The vendor pays the fee, but vendors commonly pass it on to buyers in the statement of adjustments, and not all do. Whether it appears on your closing figures depends on your agreement, so check your statement of adjustments and ask a lawyer if you are unsure.

Is the interim occupancy fee part of my purchase price?

No. It is not credited to the purchase price, and you owe it whether or not you move in. It also cannot exceed the total of interest on the unpaid balance, estimated municipal taxes and projected common expenses.

Can I cancel because the price went up?

Not automatically. The 10-day cooling-off period to rescind comes early in the process, so it is generally long past by the time you reach closing. A buyer may also rescind after a material change in the disclosure statement, and you have 30 days to terminate if the unit is not ready by the Outside Occupancy Date. A price increase alone depends on your agreement, so get advice first.
