An assignment sale is a transaction in which the original buyer transfers their contractual interest in an Agreement of Purchase and Sale (APS) to a new buyer before the original buyer takes title. In Ontario, the new buyer, called the assignee, ordinarily completes the purchase directly with the builder or original seller, subject to the original contract and any required consent.
A real estate assignment sale can create an exit for an original purchaser or an opportunity for a new buyer to acquire a unit in a project that may no longer be selling directly from the builder. It is not, however, a simple replacement for a regular resale: the original APS, every amendment, the builder’s requirements, deposits, financing and tax consequences all need to be reviewed before anyone commits.
What is an assignment sale in real estate?
An assignment sale transfers the original purchaser’s rights, and usually their obligations, under an APS to another purchaser before title transfers. The assignor does not sell a property they own; they sell or transfer their contractual position in the purchase.
In a condo assignment sale, the assignor may have signed for a pre-construction condominium several years before completion. If the assignment is permitted and completed properly, the assignee steps into that purchase arrangement and later takes title from the builder at final closing. The original APS remains a central document throughout the transaction.
For example, an original purchaser signs an APS for a $720,000 pre-construction Toronto condo, pays scheduled deposits of $108,000, and later decides not to proceed. A prospective assignee may agree to reimburse the $108,000 in documented deposits and pay additional negotiated assignment consideration. If the builder consents and all contractual requirements are met, the assignee, rather than the original purchaser, will generally be the person who completes the eventual purchase from the builder.
An assignment may also arise in a resale transaction where a buyer has signed an APS but has not yet closed. Whether it can proceed depends heavily on the wording of that agreement, the parties’ circumstances and any consent that is required.
Assignment sale vs. a regular resale
An assignment is not the same as a completed resale because the assignor has not yet taken title to the property. In a regular resale, an owner transfers their registered ownership to a buyer; in an assignment, the original contract is transferred before that ownership transfer occurs.
On a regular resale, the seller and buyer close with each other, and the buyer’s real estate lawyer registers the transfer in the Ontario electronic land registration system. On an assignment, the assignee commonly closes with the builder or original seller under the original APS, while the assignment agreement sets out what the assignee owes the assignor and which obligations are being assumed.
Pre-construction condos are the most familiar setting because construction and final closing may be separated by years. But an assignment sale Ontario transaction can involve a freehold townhouse, detached home or resale condominium purchase if the APS allows it or the necessary parties agree. A contract that prohibits assignments, requires consent, restricts marketing, or imposes conditions can materially change the deal.
Who is involved in an Ontario assignment sale?
An Ontario assignment sale usually involves an assignor, an assignee and the builder or original seller. Each has a separate role, and the assignor is not automatically released from obligations simply because an assignee has been found.
- Assignor: the original purchaser under the APS who wants to transfer their contractual position.
- Assignee: the incoming purchaser who agrees to acquire that position and, where required, assume the obligations in the original APS.
- Developer or builder: the party selling a pre-construction home or condo under the original APS. The builder may have to approve the assignment and may impose conditions or fees under the contract.
- Original seller: in a resale assignment, this is the property owner who originally signed the APS with the assignor.
- Real estate broker or salesperson: may market the assignment and help negotiate business terms, but the listing is not a substitute for review of the APS and related documents.
- Real estate lawyers: each party should have separate legal advice. The lawyers review and prepare documents, advise on risk and payment arrangements, and coordinate the eventual closing work.
Does an Ontario assignment of an Agreement of Purchase and Sale require developer consent? Often it does, particularly for a pre-construction purchase, but the answer comes from the original APS, amendments and the builder’s written requirements. An APS may permit assignments on stated conditions, prohibit them, require consent, charge an administrative fee, restrict advertising, or say whether the original purchaser remains liable after an assignment.
How an assignment sale works in Toronto and the GTA
An assignment sale in Toronto and the GTA generally starts with a review of the original purchase package and ends with the assignee completing the original purchase. The process should be documented in writing because several payments, deadlines and approvals may be involved.
- Review the original APS package. The assignor’s lawyer reviews the APS, amendments, disclosure documents, upgrade agreements, incentives, deposit schedule, notices and assignment language. The assignee needs the same information before deciding whether to proceed.
- Obtain the builder’s requirements. If a builder’s approval is required, the parties should obtain the required forms, fees, deadlines, credit or identity checks and any conditions in writing. Do not assume that verbal permission is enough.
- Negotiate the assignment agreement. The agreement should identify the original APS, the assignment consideration, deposits to be reimbursed, conditions, timing, required consents, who pays particular fees, and what happens if the builder does not approve the assignment.
- Address conditions and financing. An assignee may need time to review documents, obtain financing advice or satisfy a condition. The original APS may still have approaching deposit or other deadlines while these issues are being addressed.
- Document and handle payments. The parties arrange how deposits and assignment consideration will be held, released or credited. A listing brokerage’s trust account or a lawyer’s trust account may be used where appropriate and agreed, with clear written instructions.
- Complete occupancy and final closing. For a condominium, interim occupancy may occur before final closing. The assignee must be prepared for the obligations that arise at each stage and eventually close with the builder.
A buyer considering a pre-construction unit should obtain legal advice on the original contract early. Our lawyer for a condo purchase can review the purchase structure and the documents that affect occupancy and final closing before the buyer becomes bound.
For example, consider an assignee buying a $680,000 unit in a near-complete GTA condominium. The agreement may require the assignee to reimburse $95,000 in deposits, pay $35,000 in assignment consideration, take over one remaining $15,000 builder deposit, and later arrange funds for the balance due at final closing. If interim occupancy begins first, the assignee may also need to make occupancy payments before title can transfer. Those are distinct timing and cash-flow issues, not one single closing payment.

What an assignee should review before buying an assignment
An assignee should review the full original purchase package and confirm the assignor’s status before signing an assignment agreement. Assignment sale listings can identify a possible opportunity, but they do not replace the underlying contract, proof of payments and written builder requirements.
Before you buy an assignment, ask for and review the following:
- the complete signed APS, all schedules and amendments;
- the builder’s assignment clause, current assignment instructions and fee information;
- all upgrade agreements, incentive agreements, décor selections and change orders;
- proof of every deposit the assignor says they paid, including receipts and relevant trust records;
- written confirmation, where available, of whether the assignor is in default or has missed any payment or notice deadline;
- the remaining deposit schedule, estimated occupancy date and estimated final-closing date;
- disclosure documents, expected occupancy charges, adjustments and any builder levies described in the APS;
- the exact unit, locker, parking space and included features being transferred;
- the assignee’s financing plan for both the assignment payments and the later builder closing; and
- the builder’s consent requirements and whether the original purchaser remains liable after consent.
Original incentives and upgrades do not necessarily carry over simply because they appear in a listing. The assignment agreement and builder’s written position should state what transfers. A builder incentive may be personal to the original purchaser, conditional on closing, or affected by an assignment. Read more about builders and assignment incentive issues before treating an advertised incentive as part of the assignee’s purchase.
For a Toronto condo assignment, a lawyer should compare the listing details against the APS rather than relying on a description of the suite or projected completion date. Buyers seeking advice on a Toronto condo assignment should bring the original APS and every amendment to the review.
Deposits, assignment price and assignment fees
The assignee may reimburse the assignor’s documented deposits and pay separate assignment consideration, but the payment structure must be clearly set out in the assignment agreement. The APS and the assignment agreement should identify who holds each payment, when it is released and what happens if a condition or required consent is not satisfied.
“Assignment price” can describe different things in different listings. It may mean the amount paid to the assignor beyond reimbursement of deposits, or it may be presented alongside the original purchase price and the remaining builder balance. A buyer should ask for a full payment breakdown rather than assume that a headline price is the total cost.
| Payment or cost | What it may cover | What to confirm |
|---|---|---|
| Deposit reimbursement | Amounts the assignor already paid to the builder | Receipts, total paid, holder of funds and release terms |
| Assignment consideration | Negotiated amount paid for the assignor’s contractual position | Amount, tax treatment, timing and conditions for release |
| Remaining builder deposits | Deposits still due under the original APS | Due dates, payment method and consequences of late payment |
| Builder assignment or administration fee | Fee charged under the original APS or builder policy | Amount, taxes, payer and timing |
| Final-closing funds | Balance of purchase price, adjustments and closing costs | Estimated amount, financing and closing date |
Who pays the assignment fee? There is no universal answer. The original APS may identify the responsible party, or the assignor and assignee may allocate the cost in their agreement, subject to the builder’s requirements. The same practical point applies to legal fees and brokerage commissions: identify the responsibility in writing instead of relying on assumptions.
Costs and tax issues to review before signing
An assignment can involve costs at the assignment stage and separate costs when the assignee later closes with the builder. Before signing, both parties should budget for builder charges, legal costs, remaining deposits, occupancy obligations, HST issues and possible income-tax consequences.
The Canada Revenue Agency (CRA) may treat the GST/HST consequences of an assignment differently depending on the facts and the nature of the rights transferred. The treatment of assignment consideration, the assignor’s status and the terms of the transaction should be reviewed with a tax professional before the agreement is signed.
At the assignee’s final closing, the assignee may also face costs under the original APS, such as adjustments, utility or meter charges, development-related charges where applicable, and condominium closing items. If the property is in Ontario and the transaction is subject to Land Transfer Tax, the assignee should budget for that tax at final closing; a property in Toronto may also attract Toronto land transfer tax.
The GST/HST New Housing Rebate and the GST/HST New Residential Rental Property Rebate have eligibility rules that depend on the transaction and intended use. An assignee should not assume that a rebate will be available, assigned or paid on a particular timetable without current tax advice and review of the builder’s documents.
Income-tax treatment is also fact-specific. An assignment gain may be characterized differently depending on the taxpayer’s intentions, activities and surrounding facts, so an assignor should obtain accounting or tax advice rather than assume the gain will receive a particular tax result.
Risks that can derail an assignment sale—and what a lawyer checks
An assignment sale can fail when the original contract is misunderstood, the builder will not consent, financing is unavailable or payment terms are poorly documented. A lawyer checks the original APS and the proposed assignment agreement to identify these risks before they become a dispute or a missed closing.
- Builder refusal or conditions: The builder may prohibit an assignment, require consent, charge fees, limit marketing or require the assignee to meet particular conditions.
- Assignor default: The assignor may have missed a deposit, breached the APS or received a notice that affects the contractual position being transferred.
- Missing deposit evidence: Without reliable proof of deposits, an assignee may not know whether they are reimbursing amounts actually paid.
- Financing gaps: A lender’s approach to an assignment, interim occupancy and the final builder closing can differ by lender and file. Financing should be investigated early.
- Changing market value: An appraisal or market change can affect financing and the economics of an assignment, even if the original APS price is fixed.
- Undisclosed obligations: Upgrades, incentives, remaining deposits, occupancy charges and final-closing adjustments can change the real cost.
- Payment-release risk: A payment released too early may be difficult to recover if consent is refused or another condition fails.
Neither party should treat an assignment as an automatic exit from the original APS. The original purchaser may remain exposed under the original contract unless the relevant documents and the builder’s written consent clearly provide otherwise.

Buying or selling an assignment: what to do next
Buyers and sellers should gather the original documents and obtain legal advice before making a binding commitment. Early review is particularly important for Toronto and GTA assignment sales because consent, deposits, occupancy and final closing may all be governed by separate timelines.
If you are selling an assignment
- Collect the signed APS, schedules, amendments, receipts, upgrades and builder correspondence.
- Ask the builder for current written assignment requirements, fees and consent steps.
- Confirm upcoming deposit dates, occupancy information and final-closing estimates.

Assignment sale FAQ
How do I buy an assignment condo?
To buy an assignment condo, first obtain the original APS, amendments, proof of deposits and the builder’s assignment requirements. Then negotiate an assignment agreement that addresses consent, payment timing, financing and final closing, with legal advice before the agreement becomes firm.
Who pays the assignment fee?
The original APS may specify who pays the builder’s assignment fee, and the assignment agreement can allocate the cost between assignor and assignee. Confirm the builder’s current amount, applicable taxes and payment deadline in writing.
Who pays HST on an assignment sale?
Who bears HST economically is a matter that should be clearly addressed in the agreement, but the GST/HST treatment depends on the transaction facts and applicable rules. Both parties should obtain transaction-specific tax advice before agreeing on a price described as inclusive or exclusive of HST.
How much do assignments cost?
The cost of an assignment depends on the negotiated consideration, deposit reimbursement, builder fees, legal fees, financing, remaining deposits, occupancy obligations and final-closing charges. Ask for a written payment schedule that separates assignment-stage costs from the assignee’s later purchase costs.
What does it mean when a property is sold on assignment?
When a property is sold on assignment, the person advertising it is usually transferring their purchase contract rather than selling registered ownership of the property. The buyer should review the original APS to understand exactly what is being acquired and whether the transfer is permitted.
Are assignment sales only for pre-construction condos?
No. A sales assignment can arise in a pre-construction condo, townhouse or detached-home purchase, and sometimes in a resale purchase before closing. Pre-construction condos are common because the period between signing and final closing can be long, but the contract terms control in every case.
Speak with a Toronto real estate lawyer
An assignment sale should be reviewed before deposits or assignment consideration are released, because the original APS and builder requirements can determine whether the transaction can proceed. Early advice can help clarify the payment structure, consent requirements and final-closing obligations.
