Quick answer · What is an assignment sale?
An assignment sale lets you buy a new home or condo before it's built by taking over the original buyer's contract with the builder. You repay their deposit plus their profit now, the builder must usually agree in writing, and you pay the builder the rest at closing. GST or HST can apply to the profit.

For buyers
Checked against the sources listed, September 25, 2026. This is general information, not legal or tax advice.
An assignment sale is when the original buyer of a new, not-yet-completed home (the assignor) sells their rights and obligations under the agreement of purchase and sale with the builder to someone else (the assignee), who then closes with the builder.

Since May 7, 2022, all assignment sales of newly constructed or substantially renovated residential housing are taxable for GST/HST. For assignment agreements entered into after May 6, 2022, an amount that reimburses the assignor's deposit to the builder can be excluded from the taxable amount when the assignment agreement states that part of the price is for that deposit reimbursement.

On a new condominium unit, the builder must hold deposit money in trust under the Condominium Act, and the new home warranty protects up to $20,000 if a deposit was not placed in trust. On a new freehold home, Tarion covers the deposit up to $60,000 on homes priced at $600,000 or less, and 10% of the price up to $100,000 above that.

Whether a unit can be assigned, and on what terms (for example the builder's written consent or an assignment fee), is set by the assignment clause of the original agreement of purchase and sale. Read that clause, with a lawyer, before you commit.

11 as of November 2026: 11 active MLS® listings whose descriptions identify them as assignment sales, and 0 assignment projects listed with Summitly.
Yes, generally. Since May 7, 2022, all assignment sales of newly built residential housing are taxable for GST/HST. For agreements after May 6, 2022, the part of the price that reimburses the original buyer's deposit can be excluded when the assignment agreement says so in writing (Canada Revenue Agency).
Deposits on new condominium units must be held in trust by the builder under the Condominium Act; on new freehold homes Tarion protects the deposit up to $60,000 at $600,000 or less, and 10% of the price up to $100,000 above that (Tarion). Confirm with your lawyer how the deposit moves to you.
That depends on the assignment clause in the original agreement of purchase and sale: many require the builder's written consent and some charge a fee. Have a lawyer review the clause before you sign.
Our own assignment listings, plus active MLS® sale listings whose public remarks say "assignment sale" or "assignment of agreement" (phrases that say it is not an assignment are excluded). The MLS® has no dedicated assignment field, so an assignment described differently may be missed.
