Assignment Sales in Ontario: What Pre-Construction Buyers Need to Know

Updated November 8 2026

When you buy a pre-construction home in Ontario, you may be signing an Agreement of Purchase and Sale years before the property is completed.

A lot can change during that time.

You might:

This is where an assignment sale may become important.

An assignment can allow the original purchaser of a pre-construction property to transfer their contractual rights to another buyer before final closing.

But assignment sales are often misunderstood.

A “free assignment” does not necessarily mean you can sell whenever you want.

Builder approval may still be required. Restrictions can apply. HST can apply to the assignment transaction. Income-tax consequences can also be significant.

Before buying pre-construction with the idea that:

“I can always assign it later,”

you need to understand how assignments actually work.

Here’s what Ontario buyers should know in 2026.

What Is an Assignment Sale?

An assignment sale occurs when the original purchaser of a pre-construction property transfers their rights and obligations under the Agreement of Purchase and Sale to another purchaser before the original buyer takes legal ownership.

The original purchaser is called the:

Assignor

The new purchaser is called the:

Assignee.

The builder remains the party ultimately selling the completed property.

The assignor is therefore not technically selling a home they already own.

They are transferring their contractual interest in the future purchase.

A Simple Assignment Example

Suppose you sign an Agreement of Purchase and Sale with a builder for:

$800,000.

You pay:

$80,000

in builder deposits.

The property is expected to close in 2028.

In 2027, your circumstances change and you no longer want to complete the purchase.

The builder permits assignment.

You find another buyer willing to take over your contract.

That purchaser becomes the:

Assignee.

You become the:

Assignor.

The assignee agrees to assume your contractual obligations and eventually close the property with the builder, subject to the assignment agreement and builder approval.

An Assignment Is Not the Same as a Resale

This distinction is extremely important.

In a resale transaction:

You own the property and sell the property.

In an assignment:

You generally do not own the property yet.

You are selling or transferring:

Your contractual rights to purchase it.

That means the transaction can involve:

Assignments can therefore be significantly more complicated than ordinary resale transactions.

Why Do Buyers Assign Pre-Construction Properties?

There are many legitimate reasons.

Change in Financial Situation

A buyer may no longer qualify for financing.

Employment Relocation

The purchaser may move to another city or province.

Family Changes

The property may become too small or no longer suitable.

Relationship Changes

Marriage, separation or divorce can change housing plans.

Change in Investment Strategy

An investor may decide not to hold the property.

Market Opportunity

A purchaser may choose to realize value in the contract before final closing.

Whatever the reason, assignment flexibility can be valuable when you’re committing to a property several years in advance.

Does Every Builder Allow Assignments?

No.

This is one of the most important things to understand before buying.

Your ability to assign depends primarily on:

Your Agreement of Purchase and Sale.

A builder may:

Never assume:

“It’s pre-construction, so I can assign it.”

You may not be able to.

What Does “Free Assignment” Actually Mean?

Builders frequently advertise:

Free Assignment

as an incentive.

This usually means the builder is waiving a particular assignment administration fee.

It does not necessarily mean:

The exact benefit depends on the contract.

Better approach:

When a builder advertises free assignment, ask:

That’s how you determine the real value of the incentive.

Why Do Builders Restrict Assignments?

Builders generally want control over their project while it is being marketed and constructed.

Imagine a builder is selling homes at:

$800,000.

Several original buyers begin advertising assignments online at:

$750,000.

Those listings could compete directly against the builder’s unsold inventory.

Alternatively, assignments being advertised at dramatically higher prices could create other marketing or appraisal concerns.

Builders may therefore restrict:

The specific rules depend on the builder.

Can You Put an Assignment on MLS?

Sometimes.

But not automatically.

Some builder agreements prohibit public marketing or listing an assignment on MLS until certain conditions are satisfied.

Others allow marketing only after the builder gives written consent.

Violating the builder’s assignment restrictions can potentially create serious contractual problems.

Before advertising:

Read the APS.

And obtain legal advice.

How Does the Money Work in an Assignment?

This is where assignments can become confusing.

Let’s use a simplified example.

Original builder purchase price:

$800,000

Original buyer has paid builder deposits:

$80,000.

The parties agree that the new buyer will pay:

$850,000

for the contractual position.

The difference between:

$850,000

and

$800,000

is:

$50,000.

That $50,000 is often referred to informally as the:

Assignment profit.

But the actual transaction can be more complicated.

The assignee may also need to reimburse the assignor for deposits already paid.

So the assignor may expect to recover:

$80,000 deposits

plus potentially:

$50,000 assignment increase

subject to the terms of the transaction, HST, income tax, legal expenses, commission and other costs.

When Does the Assignor Get Their Deposit Back?

This depends on how the assignment agreement is structured.

The original purchaser may have already paid significant deposits to the builder.

For example:

$80,000.

The assignee may reimburse those deposits:

This is an important financial issue.

The assignor should not automatically assume that all original deposits are immediately returned as soon as an assignment agreement is signed.

The assignment contract should clearly explain:

Both parties should have lawyers involved.

The Assignee Usually Takes Over the Original Builder Contract

The assignee generally steps into the original purchaser’s position.

That means the new buyer is not necessarily negotiating a completely new builder deal.

They may inherit:

That is why an assignee needs to review:

The original builder APS

not simply the assignment agreement.

The Assignee Needs Their Own Lawyer

An assignment can involve two important contracts:

Original Builder APS

and

Assignment Agreement.

The assignee needs to understand both.

Their lawyer should review matters such as:

Do not treat an assignment as a simple resale offer.

HST on Assignment Sales: The Rule Changed

One of the most important tax issues involves HST.

Since May 7, 2022, assignment sales involving newly constructed or substantially renovated residential housing are generally taxable for GST/HST purposes.

That means:

HST can apply to the assignment transaction.

This applies even where the assignor originally intended to occupy the home rather than purchase it for investment.

That’s a major change from older rules.

Does HST Apply to the Entire Assignment Amount?

The HST calculation can be technical.

Under the current framework, amounts attributable to certain deposits originally paid by the assignor to the builder may be excluded from the taxable consideration where the required conditions are satisfied.

However, other amounts received for assigning the contract can be taxable.

This is exactly why assignment sellers should speak with:

An accountant or qualified tax professional.

Do not estimate the HST based on something you saw in an online forum.

Example of Why Assignment HST Matters

Suppose:

Original builder price:

$800,000

Deposits paid:

$80,000

Assignment price increase:

$50,000.

The assignor may think:

“I made $50,000.”

But before determining the actual net profit, they may need to consider:

The amount left in your pocket may therefore be substantially lower than the headline $50,000.

Assignment Profit Can Also Be Taxable Income

HST and income tax are separate issues.

A seller may owe:

GST/HST

on the taxable assignment transaction.

They may also owe:

Income tax

on the economic gain.

You should not assume the profit automatically qualifies as a capital gain.

The Canada Revenue Agency can consider factors such as:

Depending on the facts, assignment profit may be treated as business income rather than capital gains.

This is an area where professional tax advice is particularly important.

Don’t Assume the Principal Residence Exemption Will Protect an Assignment

A principal residence generally involves a property you actually own and ordinarily inhabit under applicable tax rules.

In a typical assignment:

You haven’t taken ownership yet.

You are assigning your contractual right before closing.

Therefore, buyers should not assume that because they originally intended to live in the property, assignment profit will automatically qualify for the principal residence exemption.

Obtain tax advice before selling.

What About the New 2026 HST Rebate?

This is another reason assignments require extra care in 2026.

Ontario’s Enhanced New Housing Rebate has important timing requirements.

For a typical purchase from a builder, qualifying agreements generally need to fall within the current program window.

Assignments can create additional eligibility issues.

For Ontario’s enhanced rebate, both the underlying builder purchase agreement and assignment timing can matter under the applicable rules.

Therefore:

Do not assume the assignee automatically receives every rebate the original buyer expected.

The assignee should independently confirm eligibility based on:

This should be reviewed before making the assignment firm.

Builder HST Pricing Can Also Create Confusion

Suppose the original builder price says:

$799,990

including applicable HST rebates.

The original purchaser intended to live in the home.

Then they assign it.

The assignee plans to use the home as:

An investment property.

The HST treatment may not be identical.

The builder may have assumed that certain owner-occupied rebates would apply.

If the ultimate purchaser doesn’t satisfy those requirements, additional funds could potentially be required.

This is why:

HST must be reviewed before assignment closing and builder closing.

Investors May Have Different Rebate Rules

An assignee purchasing the property as a long-term rental may potentially need to consider the New Residential Rental Property Rebate framework rather than the ordinary owner-occupied new-housing rebate.

The requirements are different.

Cash-flow timing can also differ.

An investor should therefore not rely on:

“HST included”

without understanding exactly which rebate assumption is built into the builder’s price.

Can the Builder Charge an Assignment Fee?

Yes, if permitted by the contract.

Builder assignment fees can vary significantly.

You may see:

This is why an assignment clause can have real financial value.

Suppose two otherwise similar homes have:

Project A

Assignment fee:

$10,000

Project B

Free assignment.

If you later need to sell before closing, that difference suddenly matters.

What Other Costs Can an Assignor Face?

Potential assignment expenses can include:

So instead of calculating:

Assignment price − original price = profit

calculate:

Assignment Proceeds

− Taxes

− Builder Fees

− Legal Fees

− Commission

− Other Costs

= Net Result.

Can the Assignee Get a Mortgage?

Potentially, yes.

But assignment financing can be more complicated than financing an ordinary resale property.

The assignee ultimately needs financing to complete the builder closing.

Lenders may review:

Different lenders may treat assignments differently.

An assignee should speak with a mortgage professional before making the assignment firm.

The Assignment Price Doesn’t Automatically Determine Mortgage Value

Suppose:

Original builder price:

$800,000.

Assignment price:

$900,000.

The assignee shouldn’t automatically assume:

“The lender will finance based on $900,000.”

The lender may consider:

This can affect the amount of cash required.

Financing should be investigated early.

What Happens to the Original Deposits?

Suppose the assignor paid:

$80,000

to the builder.

These deposits remain credited toward the builder purchase.

The assignment agreement needs to explain how the assignee reimburses the assignor.

The builder doesn’t necessarily refund the original deposit just because an assignment occurs.

Instead, the assignee generally assumes the benefits of those deposits toward final closing while compensating the assignor according to the assignment contract.

Who Is Responsible if the Assignee Doesn’t Close?

This is another reason builder consent and legal advice matter.

Depending on the assignment documents and original APS, the original purchaser may not automatically be released from every obligation simply because they assigned the contract.

Some builder assignment approvals can preserve certain liabilities of the original purchaser if the assignee defaults.

This could be extremely important.

Ask your lawyer:

“Am I fully released after assignment?”

Do not assume the answer is yes.

Can the Assignor Still Be Liable to the Builder?

Potentially.

The exact answer depends on:

If the builder doesn’t provide a complete release, the original purchaser may retain some contractual exposure.

This is one of the most important legal questions an assignor should ask.

What Happens if Property Values Fall?

Assignments aren’t always profitable.

Suppose:

Original builder price:

$900,000

Current market value:

$800,000.

You need to exit the transaction before closing.

You may need to assign below your original contract price.

That could mean:

Assignment is not a guaranteed profit strategy.

Can You Assign Below the Original Builder Price?

Potentially, if permitted by the builder and contract.

But the economics can become difficult.

Suppose:

Original price:

$900,000.

Assignment buyer will only pay:

$825,000.

That creates a:

$75,000 difference.

The original buyer may have to absorb that loss and still consider:

This is why buyers should never purchase pre-construction believing:

“Worst case, I’ll just assign it.”

Assignments can provide flexibility.

They don’t eliminate market risk.

What Happens if Property Values Rise?

Now consider the opposite.

Original purchase:

$750,000.

Assignment market value:

$850,000.

Potential increase:

$100,000.

That may appear attractive.

But again, calculate:

before deciding how profitable the transaction really is.

Assignment Sales Can Be Harder to Market

Assignments can sometimes have a smaller buyer pool than ordinary resale properties.

Why?

Because they can involve:

That can make finding the right buyer more challenging.

Don’t assume selling an assignment will be as easy as listing a completed resale property.

When Is an Assignment Most Valuable?

Assignment flexibility can be particularly useful when:

Your circumstances unexpectedly change

This is the strongest reason to value an assignment clause.

The closing is years away

Long timelines increase uncertainty.

You are relocating

You may no longer need the home.

Your family needs change

The floor plan may no longer work.

You cannot complete financing

Assignment might provide an alternative to default, if permitted and financially feasible.

In this sense:

Assignment rights are a form of flexibility.

When Should You Be Cautious About Buying With an Assignment Strategy?

Be particularly careful if your entire purchase plan is:

“I’ll buy now and assign for profit before closing.”

That strategy depends on several things you don’t control:

If prices don’t increase—or fall—the strategy can fail.

A financially stronger approach is:

Buy a property you could comfortably close if necessary.

Then treat assignment as an option rather than the only exit.

Assignment vs Closing and Reselling

Suppose you want to exit a pre-construction investment.

There can be two broad options:

Option 1: Assign before closing

Transfer the contract to another purchaser.

Option 2: Close the property first

Take ownership and potentially sell later as a resale property.

These strategies can have very different:

Neither is automatically better.

Professional advice may be necessary before choosing.

What Should an Assignor Ask Before Listing?

Before trying to sell your assignment, confirm:

Do this before setting an asking price.

What Should an Assignee Ask Before Buying?

An assignment buyer should ask:

These questions help expose the true cost.

Example: Buying an Assignment

Suppose:

Original builder price:

$700,000.

Original buyer paid:

$70,000 deposits.

Assignment seller wants:

$50,000 premium.

The assignee’s total economic position may effectively involve:

Original contract:

$700,000

plus assignment premium:

$50,000

for approximately:

$750,000

before considering:

Now compare that with:

Current builder inventory:

$760,000

including stronger incentives.

or

Comparable resale:

$725,000.

Suddenly the assignment isn’t automatically the best choice.

Always compare alternatives.

What If the Assignment Includes Valuable Old Pricing?

This is where assignments can become attractive.

Suppose someone purchased early at:

$650,000.

Current builder price for a comparable home:

$800,000.

The assignor asks:

$725,000.

The assignee may potentially obtain a home:

$75,000 below the current builder price.

That can be valuable.

But still examine:

Old pricing can create opportunities, but only after you calculate the complete deal.

Does the New Buyer Get the Original Builder Incentives?

Sometimes.

But not necessarily every incentive transfers automatically.

The original APS may include:

The assignee should confirm that the applicable benefits remain valid after assignment.

Do not assume.

Get everything documented.

Does Tarion Warranty Still Apply?

An assignment itself does not normally turn a new home into a resale home.

The assignee who ultimately purchases the newly built property may still benefit from the applicable statutory new-home warranty framework.

However, warranty dates and procedures depend on the property and possession/closing structure.

The assignee should receive and review the relevant:

What About the Pre-Delivery Inspection?

The assignment agreement should clarify who will be entitled or expected to participate in the PDI if the assignment occurs before possession.

In many cases, the assignee will be the person ultimately preparing to take possession.

But builder procedures vary.

Confirm this before closing.

Assignment vs Builder Inventory: Which Is Better?

In today’s market, assignment buyers should always compare available builder inventory.

Suppose an assignment seller wants:

$800,000.

But the builder has a similar inventory home for:

$810,000

and offers:

The builder inventory could actually provide better value.

On the other hand, an older assignment purchased at significantly lower pricing may outperform current builder inventory.

The answer depends on the numbers.

Assignment vs Resale: Which Is Better?

Again, compare both.

An assignment may offer:

A resale property may offer:

Neither is automatically superior.

10 Biggest Assignment Mistakes to Avoid

1. Assuming assignment is automatically permitted

Check the APS.

2. Assuming “free assignment” means unrestricted assignment

It usually doesn’t.

3. Advertising without builder permission

This can violate the agreement.

4. Ignoring HST

Assignment sales can be taxable.

5. Ignoring income tax

Your profit may be taxable income.

6. Assuming you’ll recover your deposit immediately

Check the assignment payment structure.

7. Assuming your mortgage is straightforward

Assignment financing can be more complicated.

8. Buying because you expect guaranteed appreciation

There is no guarantee.

9. Failing to compare builder inventory and resale

An assignment isn’t automatically a bargain.

10. Assuming you’re completely released after assignment

Your lawyer needs to confirm this.

Frequently Asked Questions

What is a pre-construction assignment sale?

It is generally the transfer of the original purchaser’s rights and obligations under a builder Agreement of Purchase and Sale to another buyer before the original purchaser takes legal ownership.

Does the original buyer own the property during an assignment?

Usually not. The original purchaser is generally transferring their contractual interest in the future purchase rather than selling a property they already own.

Can every pre-construction home be assigned?

No. Assignment rights depend on the builder APS and builder policies.

What does “free assignment” mean?

It usually means the builder waives a specified assignment fee. Builder consent and other restrictions may still apply.

Is HST charged on assignment sales?

Assignment sales of newly constructed or substantially renovated residential housing are generally subject to GST/HST under the current federal rules.

Is assignment profit taxable?

Potentially, yes. Income-tax treatment depends on the circumstances and may differ from what some sellers expect. Professional tax advice is recommended.

Can I list an assignment on MLS?

Possibly, but only if permitted by the builder agreement and applicable builder policies.

Can an assignee get a mortgage?

Potentially, but financing assignments can be more complicated than ordinary resale transactions. Mortgage advice should be obtained before making the transaction firm.

Does the assignee get the original buyer’s deposits?

The deposits generally remain credited toward the builder purchase. The assignment agreement determines how and when the assignee reimburses the assignor.

Does Tarion warranty still apply after assignment?

A qualifying newly built home can remain subject to Ontario’s statutory new-home warranty framework. Assignment does not automatically eliminate new-home warranty coverage.

Can I assign if the property is worth less than my purchase price?

Potentially, if the builder permits it, but you may have to accept a loss.

Is assignment a guaranteed way to avoid closing?

No. Assignment depends on your contractual rights, builder approval and finding a qualified buyer. It should never be treated as a guaranteed exit strategy.

The Bottom Line

Assignment rights can be valuable.

When you’re purchasing a home that may not close for several years, nobody can predict exactly what your life will look like at completion.

Having the ability to transfer your contract can provide important flexibility.

But buyers need to understand:

Assignment Is an Option—Not a Guarantee.

Before relying on assignment, investigate:

Builder Permission

Assignment Fee

Marketing Restrictions

HST

Income Tax

Financing

Deposit Reimbursement

Legal Liability

An assignment that looks profitable on paper may look very different after taxes and expenses.

Likewise, an assignment offered below today’s builder pricing can sometimes represent an attractive opportunity for a new buyer.

The key is to calculate the complete transaction.

If you’re buying pre-construction in 2026, one of the smartest questions you can ask before signing is:

“What happens if I need to sell this contract before closing?”

Knowing the answer today can give you much more flexibility tomorrow.
