In Canada, you generally cannot sue a former employee for utilizing their general industry skills and experience at a new job. To successfully pursue legal action, an employer must clearly prove the employee stole protected trade secrets, confidential corporate data, or breached a highly specific restrictive covenant.
Employee turnover is a natural part of doing business, but it can become highly contentious when a key team member leaves to join a direct competitor or start their own rival company. Employers naturally worry that their former staff will use insider knowledge to steal clients or replicate successful internal processes.
However, Canadian employment law heavily favours a person’s fundamental right to earn a living in their chosen profession. The courts draw a very strict line between a company’s legitimate, protected intellectual property (such as client lists or proprietary software code) and the general knowledge, skills, and expertise a worker naturally acquires over the course of their career. 📊
This legal guide clarifies the important distinction between trade secrets and general knowledge, explains how restrictive covenants work in Canada, and outlines the steps employers must take to protect their confidential data.
Step-by-Step Process: Assessing IP Theft vs. General Knowledge
Whether your business operates in Alberta, British Columbia, or Ontario, the legal principles governing employee knowledge are quite consistent, though specific provincial employment standards can dictate how contracts are enforced.
Step 1: Identifying a True Trade Secret
Before taking any legal action, you must determine if what the employee took is actually a legally protected trade secret. A trade secret is highly confidential information that gives your business a competitive edge, such as a secret recipe, an unreleased product design, or a highly customized, private client database.
Conversely, general knowledge includes everyday industry practices, standard sales techniques, or public contacts. For example, knowing how to efficiently operate a standard forklift, or knowing that a certain public company is a good potential client, is general knowledge. An employee is completely free to take this information to a new job.
Step 2: Reviewing the Employment Contract
If you suspect foul play, your lawyer will carefully review the former employee’s contract. They will look for Non-Disclosure Agreements (NDAs), confidentiality clauses, and Non-Solicitation agreements. 📝
It is crucial to note that Non-Compete clauses are increasingly difficult to enforce in Canada. In fact, under the Working for Workers Act, 2021, Ontario officially banned non-compete agreements for the vast majority of employees, with exceptions only for C-suite executives or in the context of selling a business.
Step 3: Sending a Formal Warning
If there is clear evidence that the employee breached a valid confidentiality agreement or actively stole physical data (such as downloading a proprietary CRM database to a USB drive), your law firm will draft a cease and desist letter. This letter will demand the immediate return of the confidential materials and warn both the employee and their new employer of impending litigation.
Step 4: Seeking an Injunction in Court
If the employee refuses to comply, your lawyer may apply for an urgent court injunction. This is a powerful judicial order that legally forces the individual to stop using the stolen information or stop contacting your clients until a full trial can be held to resolve the dispute. ⚠️
How Much Does it Cost in Canada?
Litigating an employment intellectual property dispute is a highly expensive endeavour for a business:
- Drafting Enforceable Contracts: Preventative measures are the cheapest. Having a lawyer draft a solid employment contract with valid non-solicitation and confidentiality clauses usually costs $1,000 to $2,500 CAD.
- Cease and Desist Letter: Having a law firm investigate and send a formal warning typically costs $1,000 to $2,000 CAD.
- Seeking an Injunction: Going to court for an emergency injunction is complex and can easily cost $15,000 to $30,000 CAD in initial legal fees alone.
How Long Does the Process Take?
Time is of the essence when corporate secrets are at risk. A lawyer can typically draft and send a warning letter within a few days. If court action is required, an emergency injunction can sometimes be obtained in a matter of weeks. However, if the case proceeds to a full civil trial for financial damages, the legal process can drag on for 2 to 3 years. ⌛

Frequently Asked Questions (FAQ)
What is a restrictive covenant?
A restrictive covenant is a clause in an employment contract designed to protect the employer’s business interests. The most common types are non-disclosure, non-solicitation, and non-competition agreements.
Can I enforce a non-compete in British Columbia or Alberta?
While not strictly banned by statute like in Ontario, courts in BC, Alberta, and across Canada view non-competes as a restraint of trade. They are notoriously difficult to enforce unless they are extremely narrow in geographic scope and time, and absolutely necessary to protect the business.
What is the difference between non-compete and non-solicitation?
A non-compete prevents a former employee from working for a competitor altogether. A non-solicitation clause allows them to work for the competitor, but strictly forbids them from poaching your existing clients or staff.
Can the new employer be sued as well?
Yes. If the new employer knowingly encouraged the employee to steal trade secrets or breach their contract to gain an unfair advantage, your business may have grounds to sue the rival company directly.
