Get a clear guide about contingency fees, the rules governing them, and how to structure legally compliant fee agreements
In Ontario, "no win, no fee" is more than a slogan: it describes the contingency fee arrangements lawyers and clients can use. This article explores contingency fee agreements, summarizes the rules the Ontario lawyers must follow, and highlights pitfalls to avoid.
Under the Solicitors Act, any arrangement where part of the legal fee depends on the successful outcome of a case is a contingency fee. "A contingency fee is one way to pay a lawyer, where the lawyer is paid only if the case succeeds and is paid out of the client's recovery. This can either be from:
In a contingency fee agreement (CFA), the lawyer's fees come from a percentage of this amount that the client recovers. The percentage can also apply to the amounts that the client receives for costs. However, the percentage cannot apply to amounts allocated to disbursements or taxes.
These arrangements are common in personal injury cases. They allow injured people and their families to pursue claims even if they cannot afford lawyers' fees upfront.

Ontario lawyers and law firms must follow rules set by the following bodies when using CFAs:

The LSO recognizes several ways to structure a CFA:
Some agreements also provide a bonus or premium if the result is especially favourable to the client.
Ontario's laws do not set a single maximum percentage for contingency fees, but they do set a hard limit on outcomes.
Primarily, the contingency fee cannot be more than what the client receives from the settlement or award. For this test, the client's recovery includes damages and any costs award, but it excludes any disbursements and taxes.
On top of that, the fee must always be fair and reasonable, in relation to the case. This test on fairness has always been the common standard when lawyers use CFAs for their clients.
Generally, lawyers and paralegals must use the Standard Form CFA when charging clients via contingency fees. Exceptions to this rule are the following:
An organizational client can either be any of these:
Ontario's laws put strong emphasis on transparency. Before signing a CFA, the lawyer must explain the following main factors used to set the fee:
The client must also receive the LSO's Consumer Guide on contingency fees and be given a fair chance to read it before signing the agreement.
Some clients and cases fall under special rules where certain disclosure and form requirements do not apply:
But even where exemptions apply, the fee charged must still be fair and reasonable.
The following provisions are prohibited in a CFA, even when the Standard Form is used or edited:
Contingency fees are allowed only in certain types of work, such as in civil and tribunal matters, where a client might receive money. A typical example is personal injury litigation.
However, contingency fee arrangements are not allowed in the following:
After a successful case, the lawyer must give a detailed Statement of Account to the client. This Statement must show these crucial details:
Unless a court has already approved the contingency fee, the Statement must also:
If a law firm advertises that clients may be charged on a contingency basis, LSO rules require disclosure of the firm's general maximum percentage, depending on whetherit has a website:
A lawyer can agree to a higher percentage than the published maximum only if:
Lawyers who use contingency fees should be aware of the following pitfalls. Avoiding them protects both client relationships and compliance with LSO rules:
It's also important to distinguish proper CFAs from champertous arrangements, as discussed in Nootchtai v. Nahwegahbow Corbiere Genoodmagejig Barristers and Solicitors, 2025 ONSC 6071. Here, the court disregarded a "hybrid contingency fee agreement," despite the lawyers' success in the case, and instead awarded a much lower fee for them based on quantum meruit.
The "no win, no fee" agreement can open the courthouse door for many Ontarians, but it does not remove all risk, both for clients and their lawyers. CFAs still raise questions about costs, disbursements, and net recovery, but clear, plain‑language and legally compliant agreements can address most of these concerns.
