How much does a Cease and Desist Letter cost in Ontario?
This is a formal legal communication designed to stop a problem, create a record, and show the recipient that the issue is serious.

A cease and desist letter is a formal legal letter that demands someone stop doing something. In simple terms, it tells the recipient: stop this conduct now, or legal action may follow.
This is different from a general demand letter. A demand letter often asks someone to pay money, return property, fix a problem, or settle a dispute. A cease and desist letter is more focused on stopping ongoing or threatened behaviour. It is commonly used when the problem is continuing and the sender wants it to stop before more harm is done.
For example, a cease and desist letter may be used if someone is using your business name, logo, photos, videos, written content, product designs, confidential information, customer list, or other intellectual property without permission. It may also be used if someone is making false statements about you or your business, harassing you, contacting your customers improperly, violating a confidentiality agreement, or breaching a non-solicitation or non-compete obligation.
In Canada, intellectual property disputes are one common reason to send a cease and desist letter. The Canadian Intellectual Property Office explains that, for some intellectual property rights and non-online copyright infringement, a cease and desist letter can be sent to the infringing party as part of an enforcement strategy.
Trademark issues are another common example. If a business owns a registered trademark, Canadian trademark law gives the owner exclusive rights in certain circumstances. The federal Trademarks Act says that the right of the owner of a registered trademark to its exclusive use is deemed to be infringed by a person who is not entitled to use it under the Act. A cease and desist letter can be used to tell another person or business to stop using a confusingly similar name, logo, slogan, or brand element.
Copyright issues can also lead to cease and desist letters. This may include copying website content, using photos without permission, reposting videos, copying online courses, using software code, or reproducing written materials. The Government of Canada explains that copyright infringement can have civil or criminal consequences under copyright legislation.
Cease and desist letters are also used in defamation disputes. Defamation generally involves statements that harm someone’s reputation. In Ontario, defamation issues may involve written statements, online posts, reviews, social media comments, emails, or spoken statements. Ontario has a Libel and Slander Act, which deals with aspects of defamation law in the province. A cease and desist letter in this context may demand that the recipient stop making false statements, remove posts, preserve evidence, and avoid repeating the statements.
Another common use is harassment or unwanted contact. A person or business may send a cease and desist letter demanding that the recipient stop contacting them, stop attending at a location, stop messaging staff, stop contacting customers, or stop making threatening or abusive communications. The purpose is to create a clear written record that the conduct is unwelcome and must stop.
Cease and desist letters may also be used when someone breaches confidentiality. For example, a former employee, contractor, business partner, or supplier may be using confidential documents, internal business information, private customer data, pricing information, trade secrets, or strategy materials without permission. A letter can demand that they stop using the information, return or delete it, and confirm that they have not shared it further.
A strong cease and desist letter should be specific. It should identify the conduct being challenged, explain why the sender says the conduct is improper, demand that the conduct stop, set out any required next steps, and warn that legal action may be taken if the conduct continues. It may also demand written confirmation that the recipient will comply.
The letter should usually avoid sounding careless or overly dramatic. A cease and desist letter can be firm, but it should not make wild threats or exaggerate the legal position. If the letter is too aggressive or inaccurate, it may backfire. The recipient may ignore it, challenge it, or use it to argue that the sender is acting unreasonably.
At the same time, a well-drafted cease and desist letter can be powerful. A letter on law firm letterhead may get more attention than an informal text, email, or phone call. It shows that the sender has escalated the issue and is creating a formal record. In some cases, the letter may resolve the issue without needing to start a lawsuit.
A cease and desist letter does not automatically have the force of a court order. It is not the same thing as an injunction. If the recipient refuses to stop, the sender may need to consider court action. In Ontario, the Superior Court of Justice has broad jurisdiction, including powers historically exercised by courts of common law and equity. Depending on the case, a party may seek court remedies such as damages, an injunction, or other relief.
It is also important to choose the right type of letter. If the main goal is to collect money, a demand letter may be more appropriate. If the main goal is to stop conduct, a cease and desist letter may be the better fit. In some cases, the letter may do both, such as demanding that the recipient stop using confidential information and also pay for losses already caused.
Before sending a cease and desist letter, it is helpful to gather evidence. This may include screenshots, emails, contracts, website links, social media posts, customer messages, photos, videos, trademark registrations, copyright records, confidentiality agreements, employment agreements, or other documents. Evidence matters because the letter should be based on facts, not just frustration.
It is also important to think about timing. If harmful conduct is ongoing, delay can make the problem worse. For example, copied website content may keep attracting customers, defamatory posts may keep spreading, and confidential information may keep being shared. A clear letter can put the recipient on notice quickly.
However, sending a cease and desist letter is not always the right first move. Sometimes the situation is better handled through a softer business communication. Sometimes a lawyer’s letter may escalate the dispute. Sometimes urgent court action may be needed instead. The right approach depends on the facts, the harm being caused, and the practical goal.
