What actually happens to your contracts when your business is sold or restructured in Ontario? Contracts do not automatically move with a business the way physical assets or a bank account might.
Whether they can follow the transaction depends on what the contract itself says about assignment.
This article explains why contracts are not automatically transferable. It also covers how change-of-control provisions work, and what to check before a sale or restructuring closes.
Key Takeaways
- Contracts are not automatically transferable. They must expressly permit assignment before they can move with a sale.
- Many commercial agreements restrict assignment without the counterparty's prior written consent.
- Some contracts treat a change in ownership as a deemed assignment, even without a formal transfer.
- A deemed assignment can be triggered even if the contracting entity technically stays the same.
- Key contracts often need to be renegotiated or consented to before a transaction can close.
- Assignment issues are a common source of delay and uncertainty late in a deal.
- Reviewing assignment and change-of-control clauses early avoids surprises at closing.
What Happens to Your Contracts When Your Business Is Sold
Contracts are not automatically transferable when a business changes hands. They must permit assignment for the rights and obligations to move with the transaction. That permission needs to be either express or clearly implied.
This surprises many business owners going through their first sale or restructuring. A contract with a key supplier, a major customer, or a landlord does not simply follow the business. It does not move the way inventory or equipment does.
If the agreement is silent on assignment, general contract principles may still allow a transfer in some circumstances. But most well-drafted commercial agreements address the issue directly. That drafting controls what actually happens once a deal is on the table.
This is one reason commercial contracts for Ontario businesses need review as a full structure, not clause by clause in isolation. Assignment language rarely gets flagged as a priority until a transaction is already in motion.
Assignment Clauses and Counterparty Consent
Many commercial agreements restrict assignment without the counterparty's consent.
This means a sale or restructuring may require approval from one or more counterparties. A supplier agreement, a lease, or a services contract might each contain its own consent requirement.
Those requirements do not always surface until someone reviews the documents carefully. This is exactly the kind of gap that due diligence in an Ontario business purchase is meant to catch.
Catching it early means there is still time to adjust before the deal proceeds too far.
Where consent is required and not obtained, the assignment may be invalid. The counterparty may instead treat the attempted transfer as a breach.
Either outcome can complicate a transaction that otherwise looked straightforward on paper.
Change-of-Control Clauses in Share and Asset Sales
Some contracts treat a change in ownership as a deemed assignment. This can happen even when the contracting entity itself remains legally unchanged.
This distinction matters more than it might first appear. An anti-assignment clause restricts a party from transferring the agreement to someone else.
A change-of-control clause is different and may be triggered purely by a shift in who owns or controls the contracting party.
That is true even if the party continues to exist and continues signing its own name to invoices and correspondence. Whether a transaction falls under one of these provisions often depends on how the deal is structured.
That is one reason the choice between a share purchase and an asset purchase has consequences well beyond tax and liability.
Some contracts combine both mechanisms into a single provision. The clause might restrict assignment outright and then add that any change in a party's ownership or control will be deemed an assignment requiring consent.
Drafted this way, a counterparty can effectively veto a pure share sale. No contract is technically being transferred to anyone, yet the consent right still applies.
Reading the exact wording matters here. A broadly drafted change-of-control clause can capture transactions that a narrower one would simply let pass through.
A share sale, for example, does not usually assign the target's contracts to a new entity. The same corporation remains the contracting party throughout.
But if a contract contains a change-of-control clause, that same share sale can still trigger a default or a termination right. No formal assignment ever needs to take place for that to happen.
An asset sale works differently again. The contracts themselves typically need to be assigned to the buyer as part of the transaction.
How Contract Consents Can Delay Closing
Assignment and change-of-control issues become critical once a transaction is actually underway.
Key contracts may need to be renegotiated or formally consented to before closing can happen. A landlord may want updated financial information before agreeing to a change of tenant.
A major customer may want assurance that service levels will not change under new ownership.
A key supplier might use the moment as leverage to push for better pricing or extended terms. The supplier knows the deal depends on their cooperation. Each of these conversations takes time.
Delays and uncertainty often arise at exactly the stage when a deal is trying to move toward closing. That is exactly when the parties can least afford them.
This is one of the practical reasons why preparation matters well before a business goes to market. A seller who has reviewed what needs to be ready before selling a business can identify problem contracts early. There is still time then to renegotiate terms or seek consents on a normal timeline. That beats scrambling under closing pressure with a buyer waiting.
A well-run process often builds a contract review into the earliest stages of preparing for a sale. That beats leaving it for the buyer's due diligence team to uncover later.
Flagging a restrictive lease clause or an unusual clause months before a listing gives the seller room to negotiate. That is far better than negotiating once a buyer's closing deadline is already attached to the outcome.
Personal Guarantees Don’t Disappear in a Sale
Assignment issues are not limited to the operating contracts of the business itself.
If a personal guarantee was given alongside an existing obligation, a sale does not automatically release the guarantor. The underlying contract's assignment terms and the guarantee's own terms need separate review.
One document can survive a transaction even when the other gets renegotiated entirely. This detail often gets missed when a transaction focuses only on the operating agreements.
The supporting security and guarantee documents sitting alongside them get overlooked in the process.
Amalgamations and Existing Contracts
An amalgamation works differently from a sale. Under Ontario’s Business Corporations Act, the amalgamating corporations continue as one entity, rather than one company transferring its contracts to another.
Because of this, an amalgamation is generally not treated as an assignment in the traditional sense. The amalgamated corporation simply carries on as the contracting party.
That does not make contract review unnecessary. Some agreements expressly address amalgamations in their assignment or change-of-control language, and the exact wording still determines whether consent is needed.
Before an amalgamation proceeds, it is worth checking your material contracts for any clause that mentions amalgamation, merger, or reorganization.
The Bottom Line on What Happens to Your Contracts When Your Business Is Sold
Contracts do not move with a business unless they are structured to do so.
Assignment and change-of-control provisions determine whether existing agreements can follow a transaction cleanly. They also determine whether consent is needed along the way, or whether a contract becomes a live issue before closing.
For a buyer, confirming the legal status of the target and its agreements starts with basic verification. This includes checking the company’s standing on the Ontario Business Registry.
For both buyers and sellers, the safest approach is the same. Review every material contract for assignment and change-of-control language well before a transaction is announced, not after a counterparty raises the issue.
If you are buying a business in Ontario, contract assignment sits close to due diligence and the closing conditions that shape your timeline.

Frequently Asked Questions
Do contracts automatically transfer when a business is sold?
No. A contract only moves with a business if it permits assignment, either expressly or by implication. Many commercial agreements require the counterparty’s prior written consent.
If consent is required and not obtained, the assignment may be invalid, or the counterparty may treat the attempted transfer as a breach.
That is why assignment clauses should be reviewed early, ideally during due diligence, rather than after a counterparty raises the issue at closing.
What is the difference between an assignment restriction and a change-of-control clause?
An assignment restriction limits a party’s ability to transfer the contract itself to someone else. A change-of-control clause works differently.
It can be triggered by a shift in who owns or controls the contracting party, even when no contract is transferred at all.
Some agreements combine both, treating any change in ownership as a deemed assignment requiring consent. Drafted that way, a counterparty can effectively veto a pure share sale.
How do share purchases and asset purchases affect contracts differently?
In a share purchase, the same corporation remains the contracting party, so its contracts are generally not assigned to anyone. Change-of-control clauses can still be triggered.
In an asset purchase, each material contract typically needs to be formally assigned to the buyer as part of closing, often with counterparty consent.
Our guide to share purchase vs asset purchase in Ontario explains how this choice affects the rest of the deal.
Do personal guarantees survive a business sale or restructuring?
Often, yes. A sale or restructuring does not automatically release a guarantor. The guarantee stays in force until the lender or counterparty releases the guarantor in writing, or the underlying obligation is fully repaid.
The guarantee’s own terms need to be reviewed separately from the contract it supports. Our guide to personal guarantees in Ontario explains what guarantors are actually agreeing to and how release works.
Does an amalgamation count as an assignment of existing contracts?
Not in the traditional sense. Under Ontario’s Business Corporations Act, amalgamating corporations continue as one entity, so the amalgamated corporation carries on as the contracting party.
However, some agreements expressly address amalgamations in their assignment or change-of-control language.
Before an amalgamation proceeds, check your material contracts for any clause mentioning amalgamation, merger, or reorganization, since the exact wording determines whether consent is needed.
