Contract Privity Principles:
Breach of Contract Liability Arising Only Between Contracting Parties
Last Updated: August 23 2026
Question: Can a person without party status enforce contract rights in Ontario?
Answer: Under the privity of contract rule, contracts generally bind only the parties who signed, so a non-party usually cannot enforce contract terms in Ontario, but measured exceptions can apply (for example, third-party reliance on certain limitation clauses, contractual protections meant to benefit a third party, valid assignments, or statutory rules where rights and obligations run with land), as discussed in Greenwood Shopping Plaza Ltd. v. Neil J. Buchanan Ltd., [1980] 2 S.C.R. 228 and Brown v. Belleville (City), 2013 ONCA 148. If you are dealing with a contract you did not sign, SFG Paralegal Services LLP can help you assess whether an exception or assignment applies to your situation and what steps to take next, call (888) 398-0121 in Ontario to get started with a paralegal-led review.

Can a Person Without Party Status Have Contract Rights?
Privity of contract principles confine the rights and responsibilities as provided within a contract solely to the contracting parties. The principle states that only the parties to the contract can enforce the rights and responsibilities of the contract; and accordingly, third parties are unable to enforce the terms of the contract.

The Law
The privity of contract principle was explained within the cases of Greenwood Shopping Plaza Ltd. v. Beattie et al., [1980] 2 S.C.R. 228, as well as Brown v. Belleville (City), 2013 ONCA 148, wherein it was stated:
The rule relating to privity of contract has been stated in many authorities in sometimes varying form, but a convenient expression may be found in Anson’s Law of Contract, 25th ed., 1979, p. 411, in these terms:
We come now to deal with the effects of a valid contract when formed, and to ask, To whom does the obligation extend? What are the limits of a contractual agreement? This question must be considered under two separate headings: (1) the imposition of liabilities upon a third party, and (2) the acquisition of rights by a third party. We shall see that the general rule of the common law is that no one but the parties to a contract can be bound by it, or entitled under it. This principle is known as that of privity of contract.
[73] The common law doctrine of privity of contract, an established principle of contract law, stands for the proposition that "no one but the parties to a contract can be bound by it or entitled under it": Greenwood Shopping Plaza Ltd. v. Neil J. Buchanan Ltd., 1980 CanLII 202 (SCC), [1980] 2 S.C.R. 228, [1980] S.C.J. No. 59, at para. 9. See, also, London Drugs Ltd. v. Kuehne & Nagel International Ltd., 1992 CanLII 41 (SCC), [1992] 3 S.C.R. 299, [1992] S.C.J. No. 84, at p. 416 S.C.R.; Dunlop Pneumatic Tyre Co. v. Selfridge & Co., [1915] A.C. 847 (H.L.), at p. 853 A.C. ...
Exceptions
In recent years, the privity of contract principle appears as becoming more relaxed than the hardened rule such was in the past. The recent case of Seelster Farms et al. v. Her Majesty the Queen and OLG, 2020 ONSC 4013, explained such where it was said:
[184] The historical reticence of the court to find a contract where the third-party claimant is not party to a contract, or to recognize a claim of a third-party beneficiary in a contract between others, has been relaxed to a measured extent in recent years. In London Drugs Ltd. v. Kuehne & Nagel International Ltd., 1992 CanLII 41 (SCC), [1992] 3 S.C.R 299, the Supreme Court of Canada held that third parties, such as employees of an insured, are able to rely on a limitation of liability clause in a contract even though they are not parties to it. Similarly, in Fraser River Pile & Dredge Ltd. v. Can-Drive Services Ltd., 1999 CanLII 654 (SCC), [1999] 3 S.C.R. 108, the Supreme Court allowed an incremental exception to the privity rule to find that a third party was able to rely on a contractual provision to defend an action brought by one of the parties to a contract.
Assignment
Some contract rights, such as the right to collect a debt, may be assigned to a third party. Generally, an assignment must adhere to the Conveyancing and Law of Property Act, R.S.O. 1990, c. C.34, which requires, among other things, that written notice of the assignment be provided to the contract parties who may be affected by the assignment of the rights or debts prescribed within the contract; however, in some circumstances, equitable assignment principles may allow for the assignment of rights or debts without complying with the Conveyancing and Law of Property Act mandates. Such was explained within the case of Nadeau v. Caparelli, 2016 ONCA 730, where it was said:
[19] Equity does not require a particular form to effect a valid assignment, but whatever form is used must clearly show an intention that the assignee is to have the benefit of the debt or chose in action assigned: Halsbury’s Laws of Canada, “Personal Property and Secured Transactions” (Markham: LexisNexis Canada, 2013), at HPS-110 and HPS-111; G.H.L. Fridman, The Law of Contract in Canada, 6th ed. (Toronto: Thomson Reuters Canada, 2011), at pp. 648-49. As summarized by Michael Furmston in Cheshire, Fifoot & Furmston’s Law of Contract, 16th ed. (Oxford: Oxford University Press, 2012), at p. 636:
The transaction upon which the assignee relies need not even purport to be an assignment nor use the language of an assignment. If the intention of the assignor clearly is that the contractual right shall become the property of the assignee, then equity requires him to do all that is necessary to implement his intention. The only essential and the only difficulty is to ascertain that such is the intention. [Citations omitted.]
Beneficiaries
Parties to a contract may also negotiate terms that will bestow or enure a benefit that will favour a third party. In such circumstances, if the party or person with the power to deliver the benefit to the third party fails to do so, the third party, as the beneficiary to the benefit, may enforce the contract terms. This third party right to enforce a contract was stated within the case of, among others, Ferraro et al v. Neilas et al, 2022 ONSC 2737, wherein it was said:
[89] When a trustee fails or refuses to take action to enforce contractual terms, the beneficiaries can, a traditional exception to the doctrine of privity of contract. See: Greenwood Shopping Plaza Ltd. v. Neil, J. Buchanan Ltd., 1980 CanLII 202 (SCC), [1980] 2 SCR 228 (SCC), at para. 239.
Statutes
Statutory provisions imposing an assumption of contractual obligations such as laws addressing rights or duties that run with the land following a purchase. As an example, the Residential Tenancies Act, 2006, S.O. 2006, Chapter 17, mandates that the purchaser of a premises tenanted for residential purposes must assume the contractual obligations contained within the lease terms as existing between the selling landlord and the residing tenants. Specifically, the Residential Tenancies Act, 2006, states:
18 Covenants concerning things related to a rental unit or the residential complex in which it is located run with the land, whether or not the things are in existence at the time the covenants are made.
Conclusion
Generally, privity of contract principles restrict the right to enforce contract terms solely to the parties to the contract; however, there are exceptions.
