What is an assignment sale in real estate?

An assignment sale is when the original buyer of a pre-construction property sells their purchase agreement (not the property itself) to a new buyer before the development is completed and title is transferred. The new buyer (assignee) steps into the original buyer shoes and closes with the developer on the original terms.

Are assignment sales legal in Canada?

Yes, assignment sales are legal in Canada. However, the original purchase agreement must allow assignments — many developers restrict or require consent for assignments. Some developers charge an assignment fee ($3,000–$10,000+). Municipalities and CRA treat assignment profits as taxable income.

How are assignment sales taxed in Canada?

Assignment profits are generally taxed as business income (not capital gains) because the CRA views assignments as intent to profit from a transaction rather than a disposition of a capital property. This means the profit is fully taxable at your marginal tax rate — there is no 50% capital gains inclusion rate. HST may also apply on the assignment profit.

Do I pay HST on an assignment sale?

Potentially, yes. If you are assigning a new residential unit and made a profit, CRA may consider the assignment a taxable supply subject to HST (13% in Ontario). The HST applies to the profit (the difference between the original price and the assignment price). This is a complex area — consult a tax accountant before proceeding.

Can the developer block an assignment sale?

Yes. Many developers include clauses in the purchase agreement that restrict or prohibit assignments, or require written developer consent and payment of an assignment fee. Always review the assignment clause in your APS before signing if you think you might want to assign.

Assignment Sales in Canada: How They Work, Taxes & Risks (2026)

Assignment sales have become a significant part of the Canadian pre-construction market — especially in Toronto and Vancouver. They allow original purchasers to sell their contract before closing, often at a profit. But the tax and legal implications are complex, and getting them wrong can be expensive. Here’s everything you need to know about both sides of the transaction.

How an assignment sale works

Step	What Happens	Who’s Involved
1. Original purchase	Buyer (assignor) signs APS with developer and pays deposits	Assignor + developer
2. Decision to assign	Assignor decides to sell the contract before closing	Assignor
3. Find an assignee	Assignor (or their agent) finds a new buyer	Assignor + real estate agent
4. Developer consent	Assignor requests consent from the developer (if required)	Assignor + developer
5. Assignment agreement	Assignor and assignee sign an assignment agreement	Assignor + assignee + lawyers
6. Assignee pays assignor	Deposit reimbursement + assignment profit to assignor	Assignee → assignor
7. Closing	Assignee closes with the developer, takes title, and arranges mortgage	Assignee + developer

What the assignee pays

Component	Example
Original purchase price	$550,000
Assignor’s deposits paid	$85,000
Assignment premium (profit)	$65,000
Total paid to assignor	$150,000 ($85,000 deposit reimbursement + $65,000 profit)
Mortgage at closing	$550,000 (based on original purchase price)
Effective price	$615,000 ($550,000 + $65,000 premium)

Tax implications for the assignor (seller)

This is where assignment sales get complicated. CRA has increased scrutiny on assignment profits.

Income classification

Classification	Tax Treatment	When It Applies
Business income (most common for assignments)	100% taxable at your marginal rate	CRA’s default position — intent to flip/profit
Capital gain	50% inclusion rate	Only if you genuinely intended to hold the property long-term
Adventure in the nature of trade	100% taxable (same as business income)	One-off transaction with profit intent

CRA’s position: Assigning a pre-construction contract is generally considered a profit-motivated transaction. The profit is usually taxed as business income — fully taxable at your marginal tax rate with no capital gains inclusion rate advantage.

Assignment profit tax example

Detail	Value
Assignment profit	$65,000
Marginal tax rate	43.41% (Ontario, $100K+ income)
Tax owing on assignment profit	$28,217

HST on assignment sales

Situation	HST Applicable?
Assignment of a new residential condo	Likely yes — HST on the assignment profit
Assignment of a new house/townhouse	Likely yes
HST rate (Ontario)	13%
HST on $65,000 profit	$8,450
Can you claim input tax credits?	Generally no (you’re not in the business of building)

Combined tax + HST on a $65,000 assignment profit (Ontario):

Tax	Amount
Income tax (43.41%)	$28,217
HST (13%)	$8,450
Total tax	$36,667
Net profit after tax	$28,333

Many assignors are shocked to discover they keep less than half of their assignment profit.

CRA reporting requirements

The CRA requires assignment sales to be reported. As of 2023, all assignments of Canadian residential property must be reported, and the CRA receives data from land registries and developers.

Requirement	Details
Report on your tax return	Assignment profit as business income (or capital gain if you can justify it)
HST filing	May need to register for HST and file a return
Information sharing	Developers may report assignments to CRA
Anti-flipping rule	Properties held for less than 365 days are automatically taxed as business income

Tax implications for the assignee (buyer)

Factor	Details
Purchase price (for mortgage purposes)	The original APS price ($550,000 in our example)
True cost basis	Original price + assignment premium ($615,000)
HST on the original unit	Handled through the builder (same as any pre-construction purchase)
Future capital gains	Calculated from your true cost basis ($615,000), not the APS price
Land transfer tax	Based on the original purchase price (varies by province)
