Your Situation
Picture this. You have worked for a company for years. You know its systems, its processes, maybe even some source code or a formula that took years to perfect. Now a competitor has made you an offer, or you are starting something of your own. You are not trying to steal anything. You just do not want to walk into your new role and accidentally get sued.
This is one of the most common questions we hear from employees moving to a competitor. The line between what is “yours,” meaning your own skill and experience, and what belongs to your former employer is not always obvious, and the consequences of getting it wrong can be serious.
What Is a Trade Secret?
Canadian law does not have a single statute that defines a trade secret. There is no registry, no application process, and no government office that grants trade secret status the way there is for a patent or a trademark. They are not regulated by Alberta’s Employment Standards Code. Instead, the concept has developed through court decisions over decades.
A trade secret is really just a specific, more sensitive subset of a broader category called confidential information. Things like source code, formulas, proprietary algorithms, and unique manufacturing processes tend to fall on the trade secret end of the spectrum. Customer lists, pricing structures, and general business methods often do not, because courts have repeatedly found that information of that kind can frequently be recreated independently or is not unique enough to deserve special protection.
Trade Secrets vs. Your Own Skill and Knowledge
One important distinction matters here. Trade secrets are not the same as your own skill, knowledge, and experience. The law is clear that an employer does not own the general expertise you built up while working for them. You are allowed to take your skills with you. What you are not allowed to take is the employer’s specific confidential material, like the actual source code, formula, or process itself.
How Do Employers Protect Trade Secrets?
Because there is no registration system, the only way an employer protects a trade secret is by actively keeping it secret. Courts look at things like:
- Whether access was limited to a small number of employees on a need-to-know basis
- Whether employees signed confidentiality or non-disclosure agreements
- Whether security measures were in place, such as password protection or restricted physical access
- Whether the information was clearly marked or identified as confidential
- Whether employees were reminded of their confidentiality obligations during employment and at termination
If an employer cannot show it took these kinds of steps, a court is far less likely to find that the information was ever a protectible trade secret in the first place.
Am I Allowed to Compete If I Know a Trade Secret?
Generally, yes. Alberta and the rest of Canada protect the right of employees to work in their chosen field and to compete with a former employer once the employment relationship ends. You cannot be barred from working for a competitor simply because you know things that could theoretically help that competitor.
What you cannot do is use or disclose your former employer’s actual trade secrets or confidential information to gain an advantage. The distinction matters a great deal in practice. Knowing how to do your job well, even if you learned that skill at a previous employer, is yours. Taking an employer’s actual code, formula, client database, or internal documents with you is not.
This is also where a non-compte clause sometimes enters the picture. Some employment contracts attempt to restrict where you can work after you leave, not just what information you can use. These clauses are treated very differently under Alberta law than confidentiality obligations, and many of them are not enforceable as written.

What Happens If You Misuse a Trade Secret?
If a court finds that you, or a new employer, misused a former employer’s trade secret, the consequences can include:
- A permanent injunction stopping further use or disclosure
- Damages, or alternatively an accounting of profits made from the misuse
- In some cases, punitive damages
- An award of legal costs against the losing party
- An order requiring the return or destruction of the confidential material
To succeed on a claim like this, the employer generally has to prove three things: that the information was actually confidential, that it was shared with you in circumstances that made clear it was confidential, and that you misused it in a way that caused harm. If any one of those three elements is missing, the claim should fail.
How Will the Employer React to a Breach of Obligation?
In our experience, employers tend to move quickly and aggressively when they suspect trade secret misuse, often before they have complete evidence. A typical response looks something like this.
First, the employer investigates, often hiring a digital forensics expert to examine devices, accounts, and access logs.
Second, if the employer believes there has been a serious breach. it may treat the conduct as grounds for termination for cause, which can affect severance entitlements. Termination for cause in this context is a serious step for an employer to take, and it does not automatically succeed just because misuse is alleged. Learn more about termination for cause here.
Third, the employer may seek an interlocutory injunction, an urgent court order intended to stop ongoing harm before the underlying lawsuit is even resolved. You can learn more about injunctions here.
How Do You Defend Claims of Misuse?
If you find yourself facing an allegation of trade secret misuse, there are several recognized defences, depending on the facts:
- The information was not actually confidential or was already public knowledge
- The information was not communicated to you under circumstances of confidence
- You did not actually use or disclose the information improperly
- You developed similar information independently, through your own skill, public sources, or legitimate reverse engineering
- The employer delayed too long in bringing the claim, or otherwise acquiesced to the conduct
- The employer itself acted improperly, which can limit the equitable relief available to it
These defences are highly fact specific, and the strength of any one of them depends heavily on the evidence available, including emails, device records, and the timeline of events.
Case Study: A Failed Injunction to Protect a Trade Secret
A recent Alberta decision shows how these principles play out in a real, high-stakes dispute.
The plaintiff company and the defendant company are competitors in the grain management technology space. The plaintiff sells a system used to monitor stored grain. The defendant sells a competing system, and had recently launched a new generation of that product. A former software engineer at the plaintiff company left in 2022 and was later hired by the defendant company. Before his departure, he had copied the plaintiff’s source code to a USB drive. He later copied it again to a personal laptop he also used for his work at the defendant company, and accessed it once during his time there to review server configuration information.
When the plaintiff discovered this, it sued in multiple jurisdictions, including Alberta, alleging breach of confidence and seeking an urgent injunction to stop the defendant from using the source code or selling its competing product.
The court’s analysis followed the same three-part legal test that applies to interlocutory injunctions generally: was there a serious issue to be tried, would the applicant suffer irreparable harm without the injunction, and did the balance of convenience favour granting it.
Was there a serious issue to be tried?
The court found there was a serious issue. The source code was clearly treated as confidential by the plaintiff, it was shared with the engineer under a written confidentiality agreement, and there were unexplained gaps in his evidence about exactly what he did with the code after leaving. That was enough to clear the relatively low bar required at this stage.
Did the plaintiff establish irreparable harm?
This is where the plaintiff’s application fell apart. It argued that losing its competitive advantage in the Canadian market was harm that no amount of money could later fix. The problem was evidentiary. The plaintiff had not put forward concrete information about its actual market share in Canada, how much of its revenue came from Canadian sales, or any specific customers it had lost. The court was not willing to simply assume that harm existed just because a trade secret dispute was involved. Bald assertions were not enough, and inferences need a factual foundation to rest on.
The outcome
Because the plaintiff could not establish irreparable harm, the injunction was denied, even though the underlying lawsuit may well still succeed at trial once a full evidentiary record is built.
The lesson for both employers and employees is the same. Allegations alone do not win these cases. What matters is the quality and specificity of the evidence on both sides, from the confidentiality agreement language to the actual financial impact of the alleged misuse.
The Bottom Line
Trade secret law in Canada protects genuinely secret, commercially valuable information that an employer has actively guarded, not an employee’s general skill and experience. You are allowed to take your abilities with you when you change jobs. You are not allowed to take the specific confidential material that belongs to your former employer. If you are unsure where that line falls in your own situation, getting advice before you make a move, rather than after a lawsuit lands, makes all the difference.

Frequently Asked Questions About Trade Secrets
Is a trade secret the same thing as confidential information?
No. A trade secret is a narrower, more sensitive category within the broader umbrella of confidential information. Source code, formulas, and proprietary processes tend to qualify as trade secrets. Things like customer lists or general pricing strategies are often confidential but usually do not rise to the level of a trade secret, because courts have found that information of that kind can often be recreated independently.
Can my former employer stop me from working for a competitor just because I know sensitive information?
Generally, no. Alberta law protects your right to work in your chosen field, even for a direct competitor. What your former employer can stop you from doing is using or disclosing its actual trade secrets or confidential material, not simply working somewhere that competes with it.
Do I have to sign a confidentiality agreement for something to count as a trade secret?
Not necessarily. The duty to protect a former employer’s trade secrets exists even without a written agreement, as part of an employee’s general duty of good faith. That said, a written confidentiality agreement makes the employer’s case much easier to prove and is one of the factors courts look at when deciding whether information was actually treated as secret.
What if I only remember the information instead of taking files or documents?
This is one of the most contested areas in trade secret disputes. The law draws a line between your own skill, knowledge, and experience, which you are entitled to take with you, and your former employer’s specific confidential material, which you are not. In practice, the more detailed and specific the information, the more likely a court is to find that it cannot simply be chalked up to memory or general know-how.
Can a former employer search my personal devices or accounts?
Not without your consent or a court order. If a dispute escalates, an employer may ask a court for an order allowing a forensic review of specific devices or accounts believed to contain its confidential information, but this is not something an employer can do unilaterally.
How long does trade secret protection last?
There is no fixed expiry date. Unlike a patent or copyright, a trade secret remains protected for as long as it stays secret and continues to provide a competitive advantage. Once the information becomes public, through any means, it generally loses its protected status.
Can I be disciplined or terminated for cause just for taking information, even if I never used it?
Possibly. An employer does not necessarily need to prove that confidential information was used to take disciplinary action. Simply taking or retaining material in violation of a confidentiality obligation can be treated as serious misconduct, depending on the circumstances.
What should I do if I am unsure whether something I know is a trade secret?
Get advice before you act, not after. The line between protected information and your own general experience is rarely obvious, and getting it wrong can expose you to a lawsuit even if you had no intention of doing anything improper.
