An assignment sale is the sale of your contract to buy a pre-construction condo, before the building registers and you take title. You are not selling a condo — you are selling the right to complete someone else’s purchase. Three things decide whether it works: the builder must consent (and typically charges a fee, often several thousand dollars, unless your agreement includes a free assignment clause), HST applies to your profit and frequently to the whole assignment price in ways buyers do not expect, and the market has to be there. In 2026 it often is not — GTA condo values are down about 9.4% year over year and assignment inventory is heavy, so many assignments are selling at or below the original purchase price.
The market figures in this article reflect data available when it was written. TRREB’s July 2026 report is now the most current: the GTA average selling price was $1,003,956, down 4.5% year over year, new listings fell 17.8% to 14,484, and condo apartments averaged $672,807 in the 416 and $560,923 in the 905. TRREB describes the market as tightening and setting the stage for price stability.

Assignment sales were the engine of Toronto’s pre-construction boom. Buy a unit in 2016, assign it in 2019, keep the difference, never take title, never get a mortgage. For years it worked, and an entire industry grew up around it.
It does not work like that now, and the people calling me about assignments are mostly not trying to make a profit — they are trying to get out of a closing they can no longer fund.
This guide covers both situations: how assignments actually work, and how to think about them in the current market. I will be direct about the HST issue in particular, because it is the single most expensive thing people get wrong and it is almost never explained properly at the sales centre.
Nothing here is tax or legal advice. Assignments are one of the few real estate transactions where you genuinely need both an accountant and a real estate lawyer before you sign, not after. I will show you what to ask them.
1What an assignment sale actually is
When you buy pre-construction, you sign an Agreement of Purchase and Sale with the builder. You do not own a condo. You own a contract giving you the right — and the obligation — to complete a purchase when the building is finished and registered.
The three parties
You (the assignor) — the original buyer transferring the contract.
The assignee — the new buyer stepping into your position.
The builder — who must consent, and who continues to deal with whoever holds the contract.
What the assignee is buying
They take over your position entirely: your deposits (which they reimburse you for), your obligations, and your closing date. They complete the purchase directly with the builder at the original contract price. Anything above that — your profit, if there is one — they pay to you.
Why people do it
Historically, to capture appreciation without ever taking title or arranging a mortgage. Today, far more often: because circumstances changed. Job loss, relationship breakdown, a move, or — most commonly right now — the buyer cannot qualify for a mortgage at current rates and current appraised values.
The critical distinction
An assignment before interim occupancy is different from selling during occupancy. Once you are in occupancy you are paying occupancy fees to the builder every month while you try to sell. That clock costs real money and it weakens your negotiating position, because the buyer knows it.
The bottom line: You are selling a contract, not a home. The assignee completes the purchase with the builder at your original price and pays you separately for anything above it.
2Builder consent — the gate you cannot go around
Your agreement with the builder almost certainly says you cannot assign without their written consent. That is not a formality.
What builders typically require
An assignment fee. Commonly several thousand dollars, and it varies widely by builder and project. Read your agreement — the amount, or the formula, is in there.
Restrictions on marketing. Many builders prohibit listing the unit publicly on MLS, advertising it with the project name, or using their renderings and materials. This is the most under-appreciated constraint: it means you may be selling into a restricted, semi-private market rather than the open one, which materially reduces your buyer pool and therefore your price.
Their own inventory comes first. Some builders will not consent to assignments while they still have units to sell — because your assignment competes directly with their sales office.
Approval of the assignee. The builder may require the new buyer to qualify to their satisfaction.
The free assignment clause
In the current market builders are frequently granting free assignment clauses as a sales incentive. If you are buying pre-construction now, ask for one explicitly. It costs you nothing to request and it preserves an exit that may matter enormously later.
If you already own and did not negotiate one, you pay the fee. Budget it as a real transaction cost alongside legal fees and commission.
The bottom line: Builder consent, the assignment fee and any marketing restrictions are all in your agreement of purchase and sale. Read those clauses before you plan an assignment — not after you have a buyer.
3The HST trap — read this part twice
This is where assignments go badly wrong, and where the numbers people run in their heads are usually incorrect by a large margin.
The general shape of the problem
Assignments of new residential housing can attract HST. Depending on the circumstances and how the assignment agreement is drafted, HST may apply to the assignment profit, and in some situations to a broader portion of the consideration including amounts that people assume are simply a return of their own deposits.
Separately, whether you were a builder for tax purposes — which can turn on your intention at the time you bought — affects both HST treatment and whether your gain is taxed as a capital gain or as business income. Someone who bought with the intention of assigning for profit is in a different position from someone who bought to live there and had a genuine change of circumstances.
The rebate consequence
The GST/HST new housing rebate generally requires the purchaser to occupy the unit as a primary residence. If you assign rather than close and move in, you will not be entitled to that rebate — and if the original price you were quoted was net of an assumed rebate, the assignee’s cost to close can be meaningfully higher than the contract price suggests. This surprises assignees constantly and it kills deals late.
What to actually do
Engage an accountant before you sign an assignment agreement. Ask specifically: is HST payable, on what amount, who is legally responsible for remitting it, and how should the assignment agreement allocate and document it? Ask whether your gain is a capital gain or business income.
Then have a real estate lawyer draft or review the assignment agreement so the answer is written into it. An assignment agreement that is silent on HST is a dispute waiting to happen, and the person usually left holding it is the assignor.
The rules here are detailed and they have been tightened in recent years. Do not rely on what a salesperson, a forum, or this article tells you — including me. Get it in writing from a professional who has seen your specific contract.
The bottom line: HST on assignments is complex, frequently applies more broadly than people expect, and the rebate is usually lost. This is the single most expensive thing to get wrong and it requires an accountant, not an opinion.
4Why 2026 is a hard market for assignments
Here is the honest state of the market, because pretending otherwise helps nobody.
The numbers
GTA condo apartment values are down roughly 9.4% year over year to an average near $630,688. That means a unit contracted in 2021 may be worth less today than the agreed price.
What that does to an assignment
Your assignment has to compete with three things simultaneously: other assignments in the same building, the builder’s own remaining inventory (often with incentives you cannot match), and resale units in nearby completed buildings.
The builder can offer capped development charges, decor credits and extended deposits. You cannot. That is a structural disadvantage.
The appraisal problem
This is what actually forces assignments right now. At closing, the lender funds against the appraised value, not the price you agreed to pay. If the unit appraises below the contract price, the buyer must fund the difference in cash. Many cannot — and so they try to assign instead of close.
The difficulty is that the assignee faces the identical appraisal problem. That is why assignments are clearing at or below original purchase price, and why some are not clearing at all.
What to do if you cannot close
Start early — months, not weeks, before closing. Talk to a mortgage broker about whether closing is genuinely impossible or just difficult; alternative lenders, a co-signer, or a larger down payment from savings are sometimes cheaper than a distressed assignment. Talk to a real estate lawyer about your exposure if you fail to close, which can extend well beyond losing your deposit.
Failing to close is generally far worse than assigning at a loss. Understand that difference before you decide.
The bottom line: Assignments now compete with builder inventory and resale while facing the same appraisal shortfall the assignor is trying to escape. Start early and get advice before you are out of time.
5Buying an assignment — the opportunity and the risks
The other side. In this market, buying an assignment can be genuinely attractive — but the due diligence is heavier than a normal purchase.
The advantages
Price. Motivated assignors are the most flexible sellers in the market right now.
Time. You skip the years of waiting. Occupancy may be months away rather than years.
Selection. Early buyers usually got the better floor plans and exposures. Those units come back to market through assignment.
The risks, specifically
Cash requirement. You must reimburse the assignor’s deposits — often 15–20% of the original price — in one payment, well before closing. That is a much larger upfront amount than a normal purchase deposit schedule.
HST position. Verify in writing who is responsible for HST on the assignment and whether the price you were quoted was net of a rebate you will not qualify for. This is where assignment purchases blow up.
Builder consent. Not yours to control, and it can be refused.
You inherit the contract as written. Uncapped development levies, closing adjustments, occupancy fee terms — all of it. Read the original agreement of purchase and sale in full, not a summary.
Financing. Not all lenders finance assignments, and those that do may have additional conditions. Confirm with a broker before committing.
The bottom line: Assignments are the best-priced pre-construction available right now, but you take on the original contract in full and you need a large lump-sum deposit. Have a lawyer read the original agreement before you sign anything.

| Assignment fee | Usually assignor | Exact amount or formula in your agreement; free assignment clause? |
| Marketing restrictions | Assignor | Can it be listed publicly? Can the project be named? |
| HST | Both — get an accountant | On what amount, who remits, how the agreement allocates it |
| New housing rebate | Assignee | Was the quoted price net of a rebate you will not qualify for? |
| Deposit reimbursement | Assignee pays assignor | Lump sum, often 15–20% of original price, due early |
| Financing | Assignee | Will your lender finance an assignment at all? |
| Original contract terms | Assignee inherits | Development levy caps, closing adjustments, occupancy terms |

Frequently asked questions
What is an assignment sale in Toronto?
An assignment sale is the sale of your contract to purchase a pre-construction condo, before the building registers and title transfers. You are not selling a condo — you are selling the right and obligation to complete the purchase. The new buyer, called the assignee, reimburses your deposits, takes over your position with the builder, completes the purchase at the original contract price, and pays you separately for any amount above it. The builder must almost always consent.
Do I have to pay HST on an assignment sale?
Often yes, and the treatment is more complex than most people expect. HST can apply to the assignment profit, and depending on circumstances and how the assignment agreement is drafted it may apply to a broader portion of the consideration. Whether you are considered a builder for tax purposes — which can turn on your intention when you originally bought — also affects whether your gain is taxed as a capital gain or as business income. You should engage an accountant before signing an assignment agreement to confirm what HST is payable, on what amount, and who is responsible for remitting it, and have a real estate lawyer write that into the agreement.
How much does a builder charge for an assignment?
Assignment fees vary widely by builder and project and are commonly several thousand dollars. The exact amount or the formula will be set out in your agreement of purchase and sale. Builders may also impose marketing restrictions, such as prohibiting a public MLS listing or use of the project name, and some will not consent to assignments while they still have their own inventory to sell. In the current market many builders are offering free assignment clauses as an incentive to new buyers — ask for one explicitly if you are buying pre-construction now.
Can I sell my pre-construction condo before closing?
Usually only by assignment, and only with the builder’s written consent. Your agreement of purchase and sale will set out whether assignment is permitted, what fee applies, and what restrictions attach — including whether you can market the unit publicly. Some builders refuse consent entirely while they have unsold inventory. Read those clauses before making plans, because they determine whether an assignment is realistically available to you.
Is it a good time to sell an assignment in 2026?
It is difficult. GTA condo apartment values are down roughly 9.4% year over year to an average near $630,688, assignment inventory is heavy, and your assignment competes against other assignments, the builder’s remaining stock with incentives you cannot match, and resale units nearby. Many assignments are clearing at or below the original purchase price. If you are assigning because you cannot fund a closing, start months ahead rather than weeks, and get legal advice — failing to close is generally far worse than assigning at a loss, and your exposure can extend beyond losing your deposit.
Is buying an assignment a good deal?
It can be one of the better-priced ways into pre-construction right now, because motivated assignors are the most flexible sellers in the market and early buyers typically hold the better floor plans and exposures. The risks are real though: you must reimburse the assignor’s deposits in a single lump sum, often 15 to 20% of the original price and well before closing; you inherit the original contract in full including any uncapped development levies; the builder must still consent; not all lenders finance assignments; and you must verify the HST position in writing, including whether the quoted price assumed a rebate you will not qualify for. Have a real estate lawyer read the original agreement of purchase and sale before you sign.
An assignment sale in Toronto is the sale of a contract to purchase a pre-construction condominium before the building registers and title transfers. The original buyer, the assignor, transfers their position to a new buyer, the assignee, who reimburses the deposits, completes the purchase with the builder at the original contract price, and separately pays the assignor any amount above it. Builder consent is almost always required and builders typically charge an assignment fee of several thousand dollars, may restrict public marketing including MLS listing, and may refuse consent while they still hold unsold inventory. Many builders currently offer free assignment clauses as a purchase incentive. HST can apply to assignment profit and in some circumstances to a broader portion of the consideration, and the GST/HST new housing rebate is generally lost because it requires the purchaser to occupy the unit as a primary residence; an accountant should confirm the position before an assignment agreement is signed. In 2026 the assignment market is difficult because GTA condo apartment values are down roughly 9.4% year over year to an average near $630,688, assignments compete with builder inventory and resale stock, and units frequently appraise below their contract price, requiring buyers to fund the shortfall in cash at closing.
