Novation (vs. Assignment)
Novation is a three-party agreement that extinguishes an existing contract and replaces it with a new one, usually substituting a new party for an original party, which is then released. In National Trust Co. v. Mead (1990), the Supreme Court of Canada treated the creditor's assent as crucial: the new party must assume complete liability, and the creditor must accept it as principal debtor and accept the new contract in full substitution for the old. An assignment, by contrast, transfers contractual benefits and leaves the original party liable.

Key Takeaways
- Novation replaces an existing contract with a new one and releases the outgoing party, and it cannot happen without the counterparty's agreement.
- An assignment transfers contractual benefits, while the original party stays liable for performance unless the counterparty releases it.
- National Trust Co. v. Mead requires the new party to assume complete liability and the creditor to accept both the new party as principal debtor and the new contract in full substitution for the old.
- Courts are reluctant to infer novation from conduct, so a party that needs a release should obtain it in a written agreement signed by the counterparty.
- Share purchases and amalgamations do not require novation because the contracting corporation continues, though change of control and amalgamation clauses still need review.
What Is Novation?
Novation is how a party gets out of a contract and puts someone else in its place. The Supreme Court of Canada, in National Trust Co. v. Mead, [1990] 2 S.C.R. 410, described it as a trilateral agreement by which an existing contract is extinguished and a new contract is brought into being in its place.
The doctrine exists because of a basic rule of contract law. A party is generally free to assign the benefits of a contract, such as the right to be paid, to a third party. It cannot assign its obligations. Two principles combine to produce that result: people may choose whom they contract with, and people are not bound by obligations they had no part in creating. A creditor who agreed to be paid by one company cannot be forced to accept a different company in its place.
Novation is the exception, and it turns on the counterparty's consent. In practice, the outgoing party, the incoming party and the counterparty all sign an agreement that the old contract ends and a new one with the incoming party takes its place. Once that happens, the counterparty can no longer look to the original party if the new party fails to perform. That release is what makes novation valuable to a seller, and why counterparties are cautious about giving it.
Novation vs. Assignment
The two are often confused because both move a contract from one party to another. The legal effect is very different.
| Assignment | Novation | |
|---|---|---|
| What moves | Benefits, such as the right to payment | The whole contract, benefits and obligations |
| Who must agree | Assignor and assignee; the counterparty only if the contract requires consent | All three parties in practice; the counterparty's consent is essential |
| Original party afterwards | Still liable for performance | Released, from the effective date |
| Old contract | Continues | Extinguished and replaced |
| Typical document | Assignment and assumption agreement | Novation agreement |
In Ontario, section 53 of the Conveyancing and Law of Property Act lets an absolute written assignment of a debt pass the legal right to the assignee once express written notice is given to the debtor, subject to prior equities, such as defences the debtor had against the original creditor. That is the statutory route for transferring receivables, not a release of anyone's obligations.
In a typical asset deal, the buyer signs an assignment and assumption agreement promising the seller it will perform the assigned contracts. The counterparty is not a party to that promise, so it can still sue the seller if the buyer fails. The seller's main protection is the buyer's indemnity under the purchase agreement. Where the contract restricts assignment altogether, the counterparty's consent is needed before even the assignment can happen; see change of control and anti-assignment clauses.
The Legal Test From National Trust v. Mead
In Mead, the Supreme Court of Canada adopted a three-part test from Polson v. Wulffsohn (1890), 2 B.C.R. 39. For a novation:
- The new debtor must assume the complete liability.
- The creditor must accept the new debtor as principal debtor and not merely as an agent or guarantor.
- The creditor must accept the new contract in full satisfaction and substitution for the old contract.
The court stressed that assent is the crux of novation. It cannot be forced on an unwilling creditor, and without an express agreement a court should be loath to find one unless the circumstances are really compelling. Courts may consider the parties' conduct, but the burden of proving novation is not easily met. Signing an assumption agreement does not by itself create a novation.
The facts show how this plays out. Mead bought a property subject to an existing mortgage and signed an assumption agreement with the lender. The agreement said the lender could release the original borrower at any time; that was an option for the future, not a present release. The lender later discontinued a lawsuit against the original borrower, but the court held that this conduct was equivocal and found no novation.
The lesson for business owners is simple. If you need to be released, get the release in writing, signed by the counterparty. Do not rely on the counterparty accepting payments from the buyer.
When Novation Is Used
Novation comes up wherever a party wants to leave a relationship cleanly:
- Asset sales: a seller transferring a business under an asset purchase agreement may want releases on major customer, supplier or equipment contracts. Buyers usually limit novation to the contracts that matter most, because each one requires the counterparty's cooperation. The checklist for buying a business in Ontario places these consents in the wider closing process.
- Commercial leases: assigning a lease does not release the original tenant. Only the landlord's agreement does, which is a novation in substance. See lease assignment vs. sublease.
- Loans and guarantees: a lender may agree to substitute a buyer as borrower. A guarantee given for the old obligation may not extend to the new one, so lenders usually require guarantors to confirm or sign a fresh personal guarantee.
- Government contracts: federal procurement guidance requires a contractor to obtain Canada's written permission before assigning a contract, with integrity documentation for the assignee, so a sale of a government contracting business has its own consent track.
A well-drafted novation agreement names all three parties, sets an effective date, states that the incoming party assumes all obligations from that date, releases the outgoing party, and says who remains responsible for breaches that occurred before the effective date.
Practical Example
Vikram Desai's Vaughan IT company sells its managed services division to Claire Dubois's corporation for $2.4 million under an asset purchase agreement. The division has 40 client contracts. The largest is a three-year agreement worth $480,000 a year with a Brampton logistics firm, carrying service-level credits and data-breach exposure.
For the other 39 client contracts, which allow assignment on notice, the parties use an assignment and assumption agreement, with Claire's corporation indemnifying Vikram's company. For the logistics contract, Vikram insists on a novation. The client agrees after reviewing Claire's security certifications and financial statements. The three-party novation agreement makes Claire's corporation the service provider from the closing date, releases Vikram's company from performance after that date, and leaves Vikram's company responsible for $18,000 of service credits already earned before closing.
The equipment lessor consents to an assignment of a $95,000 server lease but refuses to novate it, so Vikram's company remains liable on it. The purchase agreement protects it with an indemnity from Claire's corporation and a $50,000 purchase price holdback until the lease ends.
Frequently Asked Questions
What is the difference between novation and assignment?+
An assignment transfers the benefits of a contract to someone else, but the original party remains liable if the obligations are not performed. A novation ends the old contract and creates a new one with a substituted party, releasing the original party. Assignment can sometimes happen without the counterparty's involvement; novation always requires the counterparty's agreement.
Does a novation need the other party's consent?+
Yes. Consent is the essence of novation. The Supreme Court of Canada has said novation cannot be forced on an unwilling creditor, because its effect is that the creditor gives up its right to look to the original party. Without that consent, the most a seller can achieve is an assignment backed by the buyer's indemnity.
Can novation happen without a written agreement?+
In principle, courts can infer novation from the parties' conduct, but the bar is high. Without an express agreement, a court will find novation only where the circumstances are really compelling. In Mead, even the creditor's discontinuance of its lawsuit against the original debtor was held not enough. A written novation agreement removes the doubt.
Do contracts need to be novated after an amalgamation?+
No. Under the Ontario Business Corporations Act and the Canada Business Corporations Act, the amalgamated corporation carries on with the property, rights and obligations of each amalgamating corporation, including its contracts. No assignment or novation is required. Still check each key contract for clauses that treat an amalgamation as a change of control, and notify counterparties of the new corporate details.
Is the seller still liable after an asset sale if contracts are only assigned?+
Usually yes. When a contract is assigned without a release, the counterparty can still pursue the seller if the buyer fails to perform. Sellers manage that risk with novation agreements for the most important contracts and, for the rest, an indemnity from the buyer, sometimes supported by a holdback or guarantee.
