An Assignment Sale in Ontario allows a buyer under an Agreement of Purchase and Sale to transfer their contractual rights and obligations to another buyer before closing when the contract permits it and required consent is obtained. In a wholesale real estate deal, the wholesaler is usually the assignor and the investor who takes over the contract is the assignee.
For investors, the key number is the total price after the assignment fee, deposit treatment, closing costs, repairs, financing, and exit costs are considered. In wholesaling, the assignment fee is the spread between the original contract price and the price offered to the investor. It is not a separate builder administration charge.
How a Wholesale Assignment Sale Works

A typical Assignment Sale in Ontario has three parties. The property owner signs an Agreement of Purchase and Sale with the wholesaler. The wholesaler secures the contractual right to purchase the property, then assigns that position to an investor who becomes responsible for completing the purchase under the assigned agreement.
Assume a wholesaler negotiates an existing property at $480,000 and offers the contract to an investor at $505,000.
Original contract price: $480,000
Assignment fee: $25,000
Investor’s assigned acquisition price: $505,000
The seller still receives the amount required under the original purchase agreement. The investor pays the $25,000 assignment fee for the right to step into the deal.
This is one reason investors use wholesalers when looking for off-market properties in Ontario. A wholesaler can source and negotiate the opportunity before investor involvement.
The Assignment Fee Is the Spread
For a wholesale Assignment Sale in Ontario, the calculation is straightforward:
Assignment fee = Investor’s assigned price minus original contract price
Using the same example:
$505,000 minus $480,000 = $25,000 assignment fee
There is no separate “assignment profit” line item in this example. The assignment fee is the spread.
The fee alone tells you little about deal quality. A $10,000 fee can sit inside a poor acquisition, while a $30,000 fee can still leave room if the original contract was negotiated far enough below conservative value. What matters is the investment after every cost is included.
Do Not Double Count the Deposit
Deposits are another place where assignment math can become muddled.
Suppose the wholesaler paid a $10,000 deposit under the original Agreement of Purchase and Sale. Depending on the assignment documents, the investor may need to reimburse or replace that deposit before closing.
Original contract price: $480,000
Deposit already paid: $10,000
Assignment fee: $25,000
Assigned acquisition price: $505,000
The investor may need $35,000 for the deposit reimbursement and assignment fee. If the $10,000 deposit is credited toward the $480,000 purchase price, it is not another acquisition cost.
Cash required before closing and total acquisition cost are different calculations. Have the closing lawyer confirm the flow of funds.
Underwrite the Whole Deal
Before accepting an Assignment Sale in Ontario, build your decision around total project basis, not just the difference between the seller’s contract and the assigned price.
A practical formula is:
Total project basis = Assigned acquisition price + closing costs + repairs + financing and carrying costs + resale costs + contingency
Consider a fixer-upper with these numbers:
Assigned acquisition price: $505,000
Legal, land transfer tax, and acquisition costs: $12,000
Renovation budget: $75,000
Financing and carrying costs: $20,000
Resale costs: $33,000
Contingency: $10,000
Estimated total project basis: $655,000
Assume conservative comparable sales support an after-repair value of $725,000.
$725,000 after-repair value minus $655,000 total project basis = $70,000 projected margin before income tax
Now stress-test it. If renovations run $10,000 over budget and the completed property sells for $700,000, the projected margin falls to $35,000.
The assignment fee should not be reviewed in isolation. Project economics determine return.
What Should an Investor Verify Before Taking the Assignment?
Every Assignment Sale in Ontario still requires normal due diligence. Have an Ontario real estate lawyer review the original Agreement of Purchase and Sale, schedules, amendments, and assignment agreement before committing.
At minimum, confirm:
- Assignment rights: Is the agreement assignable, and is consent required?
- Assignment fee: Is the amount, payment timing, tax treatment, and refund treatment documented clearly?
- Deposit treatment: Who paid the deposit, how will reimbursement work, and how is it credited at closing?
- Property condition: Has the property been inspected closely enough to support the repair budget?
- Title and possession: Are there liens, tenancy issues, vacant possession requirements, or unusual closing obligations?
- Financing: Can the investor fund the deal on the required closing date and in the property’s present condition?
- Exit assumptions: Are comparable sales, rents, repair costs, and resale expenses conservative?
These are also fundamentals when buying wholesale real estate in Ontario. House Deals GTA’s guidance stresses inspection, comparable sales, title review, and due diligence.
Wholesale and Pre-Construction Assignments Are Different
The term assignment is also used with pre-construction condos and new homes, but the economics are different.
In a wholesale Assignment Sale in Ontario, the assignment fee is the wholesaler’s spread. In a pre-construction assignment, a builder may separately charge a consent or administration fee for processing a change in purchaser. Calling that a builder administration fee avoids confusing it with the wholesaler’s spread.
Pre-construction assignments can also involve builder consent, occupancy costs, adjustments, upgrades, rebates, and separate GST/HST rules. CRA states that assignments of newly constructed or substantially renovated residential housing are taxable for GST/HST purposes under rules effective May 7, 2022. These issues belong in a separate pre-construction analysis.
How Is a Property Flip Taxed After Closing?
For many investors considering an Assignment Sale in Ontario, the more important tax question comes after they close, renovate, and resell the property.
CRA’s residential property flipping rule generally deems a gain from a Canadian housing unit, or a right to acquire one, held for fewer than 365 consecutive days to be business income rather than a capital gain, unless a specified exception applies. The rule specifically includes rights acquired through assignment sales.
Holding for 365 days does not automatically produce capital-gain treatment. The facts and the investor’s intention still matter, so have an accountant review the expected treatment.
HST is separate. CRA generally considers a renovation substantial when 90% or more of the existing home’s interior living area is removed or replaced, subject to detailed rules about what counts toward the test. An investor who buys intending to substantially renovate and resell can be considered a builder for GST/HST purposes, even on a one-time project. The sale is generally taxable, and registrants may be able to claim input tax credits on eligible renovation costs. A non-substantial renovation is generally treated differently, with the later sale usually exempt and renovation input tax credits generally unavailable. Review the scope with an accountant before construction begins.
What Makes an Assignment Worth Buying?
A strong wholesale assignment gives the investor enough room to absorb the assignment fee and still justify the capital, work, and risk involved.
Look for four things:
A defensible acquisition price. The assigned price should work against conservative value, not a best-case resale.
Transparent deal economics. The contract price, assignment fee, deposit, repairs, closing costs, financing, and exit assumptions should be visible.
A contract that can close. Assignment rights, title, access, financing, and possession all need to work.
Margin for error. A renovation surprise or softer resale price should not immediately eliminate the projected return.

Frequently Asked Questions
Is profit from an assignment sale taxed as capital gains or business income?
The CRA generally treats profit from an assignment sale as business income, meaning the profit is fully taxable. Consider speaking with a tax professional about your specific situation.
How does financing or a mortgage work when buying an assignment?
Financing depends on the property, lender, and terms of the assignment. Buyers should confirm their financing and available cash before committing to the purchase.
What happens to the original buyer’s deposit in an assignment sale?
The original buyer’s deposit is typically accounted for in the assignment agreement. The new buyer may reimburse the original buyer for deposits already paid, depending on the terms of the deal.
What are the risks of buying an assignment property in Ontario?
Risks can include financing issues, changes in market value, unexpected costs, and restrictions or obligations in the original purchase agreement. Always review the agreement carefully before buying.
Are assignment sales cheaper or a good investment in Ontario?
They can be if the purchase price is below current market value or offers strong investment potential. Investors should compare the total cost of the deal against its expected resale value, rental income, and risks.
