A pre-construction assignment sale transfers an original buyer’s rights and obligations under a purchase agreement to another buyer before closing. It may be an alternative to completing the purchase or selling the property after closing, but it is not automatically permitted or profitable.
The original purchase agreement, builder’s procedures, incoming buyer’s financing, deposits, and tax treatment all require careful review. Start with the contract, not an assumption that assignment is allowed.
Quick summary
- Review the purchase agreement for assignment rights, deadlines, fees, consent requirements, and default consequences.
- Obtain the builder’s current assignment process in writing before marketing the contract.
- Document deposits paid, amounts owing, closing obligations, amendments, and responsibility for each cost.
- Ask a real estate lawyer and tax professional to review the transaction.
- Do not assume builder approval, financing, tax treatment, or profit until the relevant professional confirms the facts.
What is a pre-construction assignment sale?
In an assignment, the original purchaser, known as the assignor, transfers their position in a builder’s purchase and sale agreement to another person, known as the assignee. The assignee generally takes on the contract’s rights and obligations, while the builder remains involved in the required approval process.
This is different from selling a completed home. With an assignment, title has usually not transferred to the original purchaser. The assignee is acquiring the contract position, not simply buying a finished property from an owner.
The assignment agreement should identify deposits already paid, additional consideration, future instalments, closing responsibilities, fees, and any conditions that remain. The CRA’s description of assignment sales explains the general structure, but the actual contract and transaction facts control.
Assignment, resale, or cancellation: Which route fits?
These options are not interchangeable. The best route depends on timing, contract terms, financing, and why the original buyer is considering a change.
| Option | What happens | Key questions |
|---|---|---|
| Assignment before closing | The original buyer transfers the purchase agreement to an assignee. | Is assignment allowed? Is builder consent or registration required? Who assumes the remaining obligations? |
| Resale after closing | The original buyer completes the purchase, takes ownership, and later sells the property. | Can the buyer fund closing? What ownership, financing, selling, and tax costs apply? |
| Cancellation or default | The buyer seeks to end the agreement or does not complete it. | Does the contract permit termination? What deposit or damage consequences may follow? |
An assignment does not automatically release the original purchaser. A lawyer should confirm whether liability ends when the builder approves the assignment or continues until closing.
Start with the original purchase agreement
Obtain the complete signed agreement, amendments, disclosures, addenda, builder notices, and upgrade documents. A summary from memory is not enough. Look for the exact provisions governing assignment and transfer.
- Whether assignment is permitted, restricted, or conditional.
- Whether the builder must consent, receive notice, or register the assignment.
- Assignment windows, deadlines, administrative fees, and marketing restrictions.
- Eligibility requirements for the assignee.
- Treatment of deposits, credits, upgrades, parking, lockers, and other extras.
- Whether the assignor remains responsible until formal builder acceptance or closing.
- What happens if the assignment is rejected, delayed, or incomplete.
- Default, occupancy, closing, and adjustment provisions that remain in force.
Do not rely on an informal statement that assignment is allowed. The signed agreement and the builder’s written process should guide the decision.
Confirm the builder’s assignment process
Ask the builder or sales office for current written instructions. Confirm the required forms, fees, submission deadline, notice period, supporting documents, and whether the builder deals directly with the assignee’s lawyer or lender.
Also ask whether identity documents, deposit receipts, disclosure acknowledgements, or purchaser information are required. Confirm whether the original purchaser remains liable while approval is pending and what happens if the project schedule changes.
Procedures vary by project and contract. A close deadline, incomplete file, or unconfirmed approval process is a reason to pause rather than rush.
Evaluate the contract and project
An assignee should assess both the contract and the underlying project. Review the builder, project status, unit type, floor plan, size, specifications, parking or locker rights, deposit schedule, occupancy date, final closing date, fees, and remaining obligations.
For a concrete example of the project details that require independent verification, the Grimsby Waterfront listing identifies the builder, location, status, and described property types. It also notes that prices, specifications, and promotions may change. Treat such information as a starting point, not a substitute for current builder documents.
Questions for the assignee
- Does the property suit your intended use?
- How much has the assignor paid, and how much remains due?
- Are deposit receipts available and consistent with the contract?
- Have specifications, finishes, parking, amenities, or dates changed?
- What occupancy costs, closing adjustments, or development charges may apply?
- Does the purchase still make sense if the project is delayed or market conditions change?
Check deposits, financing, and closing capacity
Create a written schedule showing every deposit paid, payment date, receipt, future instalment, assignment payment, fee, and closing cost. The assignment agreement should state whether the assignee reimburses the assignor, pays an agreed amount, or assumes future payments directly.
The assignee should speak with a lender or mortgage professional before signing. Qualification may depend on the contract price, expected closing value, income, debt, closing date, and the lender’s treatment of the assigned agreement. A pre-approval is not a guarantee of future financing.
The assignor should also confirm their exposure to the builder. Until the required approvals and documents are complete, the original purchaser may still have obligations.
Understand GST/HST and get professional advice
Tax treatment cannot be estimated from the assignment price alone. The Canada Revenue Agency states that assignment sales involving newly constructed or substantially renovated residential housing are taxable for GST/HST purposes under its cited guidance effective May 7, 2022. Review the agreement, consideration, intended use, and current rules with a tax professional using CRA guidance on assignments of new housing agreements.

- Builder: Confirms project-specific procedures, deadlines, fees, and approvals.
Step-by-step assignment checklist
- Define the reason. Identify whether the issue is changed finances, timing, relocation, or investment strategy.
- Collect the file. Gather the contract, amendments, disclosures, receipts, notices, and builder correspondence.
- Confirm permission. Check the assignment clause, deadline, fee, and restrictions with legal advice.
- Obtain builder instructions. Request current forms, documents, deadlines, and approval steps.
- Build the financial schedule. Record deposits, remaining payments, consideration, fees, adjustments, and closing costs.
- Assess the assignee. Confirm that the incoming buyer understands the contract, project, timeline, and financing requirements.
- Prepare the assignment agreement. Have counsel address conditions, payment timing, representations, approvals, taxes, releases, and default.
- Obtain tax and financing advice. Do this before signing, not after the transaction is committed.
- Complete the builder handoff. Keep written confirmation of approval, registration, document delivery, and remaining responsibilities.
Red flags that should pause the transaction
- The original agreement or amendments are missing.
- No one can identify the written assignment provision or builder process.
- Deposit amounts cannot be verified.
- A buyer is pressured to sign before receiving the documents.
- Fees, taxes, or closing responsibilities are vague.
- Someone promises guaranteed approval, financing, profit, or a quick buyer.
- The builder deadline is near and the submission package is incomplete.
- The assignee has not reviewed current project specifications and dates.
Frequently asked questions
Does the original purchase agreement have to allow an assignment?
The agreement determines whether assignment is permitted and under what conditions. Some contracts restrict assignment or require a builder process. Have a lawyer interpret the exact wording.
Is builder approval required for every assignment?
Not necessarily in the same way for every project. The contract and builder procedures determine whether consent, notice, registration, forms, or fees apply.
What happens to the deposit?
The assignment documents should state how deposits already paid are credited or reimbursed, who pays future instalments, and who is responsible if a payment is missed.
How can GST/HST apply?
CRA guidance states that assignments involving newly constructed or substantially renovated residential housing are taxable for GST/HST purposes under the cited guidance. The responsibility and reporting treatment depend on the facts.
Can an assignee obtain financing?
Possibly, but approval is not automatic. The assignee should provide the original contract and assignment documents to a lender early enough to assess qualification and timing.
Is an assignment the same as selling a completed home?
No. An assignment transfers a contractual position before closing. Selling a completed home occurs after ownership and title have transferred and involves different documents and costs.
Conclusion: Verify the contract before you decide
Pre-construction assignment sales may help an original purchaser avoid completing a purchase they can no longer carry, while giving an assignee access to a contract position. The decision should rely on verified documents, not projected profit or informal assurances.
Start with the agreement, confirm the builder’s process, document deposits and obligations, test financing capacity, and obtain legal and tax advice. If those checks produce clear answers, compare assignment with resale after closing or other contractual options.
