Selling an Assignment in the GTA in 2027: Steps, Fees and Taxes

By Jatin Dua · Broker of Record, RE/MAX Quantum Realty · Updated 2 November 2026 · 10 min read — A step-by-step guide to selling a pre-construction assignment in the GTA in 2027, with the builder fee, HST, flipping rule and pricing explained.

This guide is for GTA buyers who signed a pre-construction agreement and now want to sell it before closing. You will get the steps in order, the fees to expect, how HST and income tax apply, and how to price an assignment against today’s resale market, as of November 2026.

What is an assignment sale, and why are so many GTA buyers selling one?

An assignment is when you sell your place in a builder’s purchase agreement before the home closes. You are the assignor. The buyer, the assignee, steps into your contract, pays the builder the balance at closing and becomes the owner. You never take title.

Most assignments in 2027 will be contracts signed in 2021 to 2023, when prices were higher. Resale condo prices have fallen since then, and many buyers cannot close at the original price because the appraisal or their mortgage approval no longer matches. The table shows how far resale condo apartment medians have moved in some key GTA markets.

Across the whole TRREB area, the average condo apartment sold for $621,400 in October 2026, down 5.8% from a year earlier, according to TRREB’s Market Watch. Your assignment competes with those resale units, so price is the first thing to get right.

How do you sell an assignment in the GTA, step by step?

1. Read the assignment clause. It sits in the builder’s agreement or a schedule. It tells you whether assignment is allowed, when, whether you need written consent, the fee, and any limits on advertising. My guide to the assignment clause explains the common wording.
2. Ask the builder for its assignment package. Most builders have a form, a consent letter and a list of documents they need from the new buyer.
3. Get your numbers. List every deposit you paid, any upgrades, and the balance due at closing. You need these to price the deal and to draft the HST wording.
4. Price it against resale. Compare the assignee’s total cost (original price plus what they pay you) with similar finished units nearby.
5. Market it within the builder’s rules. Some builders restrict public advertising or MLS listings until a stage of construction. Breaking that rule can put your consent at risk.
6. Sign an assignment agreement drafted with your lawyer. It must say in writing how much of the price repays your deposit. More on why below.
7. Get the builder’s written consent and pay its fee, then hand the file to both lawyers to close.

What fees does a builder charge to approve an assignment?

There is no standard fee and no published cap. The builder’s fee, its consent conditions and any marketing limits are whatever your agreement says. That is why the clause matters more than any rule of thumb you hear.

A few points are set by law or by CRA:

• CRA says a builder’s assignment fee is generally subject to GST/HST.
• For a condo you already occupy on interim occupancy, the Condominium Act lets the builder withhold consent to assigning your right to occupy and charge a “reasonable fee” for consenting.
• Your own costs usually include legal fees for the assignment agreement and, if you use an agent, the commission you agree to. Both are negotiable.

If the clause is unclear, ask the builder for the fee and the conditions in writing before you list. You do not want to find a new condition after you have a buyer.

How much can you get for an assignment in 2027?

The buyer of your assignment pays two amounts: the payment to you, and the full balance to the builder at closing. Their total cost is the original purchase price plus your profit (or less your discount). Buyers compare that total with resale units they can close on next month.

Three things push assignment prices down in 2027:

• Resale is cheaper than it was. If similar resale units sell for less than your original price, a buyer will expect you to cover some of the gap.
• The buyer must still qualify. They need a mortgage on the full closing price, and the lender’s appraisal may come in below that price. Variable mortgage rates rose after the Bank of Canada raised its policy rate to 2.50% on 28 October 2026, and fixed rates rose with bond yields this fall.
• New launches carry big rebates. Buyers who sign a new agreement with a builder may qualify for up to $130,000 of HST relief. Your assignee probably will not, as explained further down.

On the other side, an assignment can appeal to a buyer who wants a newer unit, a closing date that suits them, or a layout that is scarce in resale.

Do you pay HST on an assignment sale in Ontario?

Yes. Under section 192.1 of the federal Excise Tax Act, an assignment of a builder’s purchase agreement for a house or condo unit, made by anyone other than the builder, is a taxable supply. CRA says this applies to assignments of new housing from 7 May 2022.

The key is how much is taxed. The law lets you take out the part of the assignment price that repays your deposit, but only if the assignment agreement says so in writing. If it does not, the deposit portion counts as taxable too. Here is a simple illustration using 13% HST:

CRA’s older info sheet GI-120 still contains an example that taxes the full amount. The statute is what applies, which is why I go deeper on this in my post on the deposit clause in assignment agreements. Have your lawyer and accountant confirm the wording.

Is assignment profit taxed as income or a capital gain?

It depends first on how long you held the contract. Since 2023, the federal residential property flipping rule in the Income Tax Act treats a gain as business income when you dispose of a housing unit, or a right to acquire one, held for less than 365 consecutive days. A pre-construction contract is a right to acquire, so the clock runs from when you signed.

• Inside 365 days, the profit is fully taxed as business income and a loss is deemed to be nil.
• The rule does not apply if the sale is due to a listed life event: death, a related person joining the household, a marriage breakdown (with 90 days apart), a threat to safety, serious illness or disability, an eligible relocation, involuntary job loss, insolvency, or destruction or expropriation.
• Held longer than 365 days, the normal tests decide whether it is business income or a capital gain. Buying to resell can still be business income.

Most 2027 assignors have held their contracts for years, so the 365-day rule may not bite, but the ordinary test still applies. Report it either way, and get an accountant’s view before you sign. I cover the cases where you simply cannot close in this post on failed closings.

What will the buyer of your assignment pay at closing?

Knowing your buyer’s costs helps you price and negotiate.

• Land transfer tax on more than the builder price. Ontario’s Ministry of Finance says the value for land transfer tax on the transfer to the assignee includes the consideration for the assignment, plus the purchase price and extras or upgrades. In Toronto, the municipal land transfer tax also applies; the buyer’s lawyer will confirm the amount.
• HST rebates may be smaller or gone. CRA allows only one new housing rebate per home, and an assignor cannot claim one. For Ontario’s enhanced new housing rebate, CRA’s Notice 346 says both the original agreement and the assignment agreement must be signed between 1 April 2026 and 31 March 2027. An agreement signed before 1 April 2026 stays “pre-April” even when assigned, so the assignee cannot get that enhanced rebate, though other rebates may still apply.
• Closing adjustments listed in the builder’s Schedule B, such as development charge increases and utility connections.

That rebate gap is a real reason a buyer may prefer a brand-new launch. Price with it in mind.

When is the best time to sell an assignment in 2027?

Earlier usually gives you more buyers and more options. Once a condo reaches interim occupancy, you may be paying a monthly occupancy fee while you wait, which I explain in my guide to interim occupancy fees. Close to final closing, buyers know you have little time, and they negotiate harder.

Timing also matters for the rebate window. If your own agreement was signed after 1 April 2026, an assignment signed on or before 31 March 2027 keeps the enhanced rebate possible for an eligible buyer, subject to CRA’s other conditions. After that date, it does not.

What to do next

1. Pull your agreement and find the assignment clause, the fee and any marketing limits.
2. Write down every deposit, upgrade and the closing balance, with dates.
3. Check the resale median for your area and similar finished units to set a realistic price.
4. Ask a real estate lawyer to draft the assignment agreement with the deposit-reimbursement wording, and an accountant to estimate your tax.
5. Read my full Toronto assignment guide, then get a price opinion before you list.
