What to Include in a Survivability Clause for Commercial NDAs in Ontario

A survivability clause in an Ontario Non-Disclosure Agreement (NDA) ensures that your confidential information remains protected even after the contract ends. Generally, standard business information should survive for 3 to 5 years, while legal protections for trade secrets must be written to survive indefinitely.

When entering into a new business venture, sharing sensitive information is often necessary to get the project off the ground. Whether you are collaborating with a tech startup in Toronto, a manufacturing facility in Mississauga, or a marketing firm in Ottawa, a commercial Non-Disclosure Agreement (NDA) is your first line of defence. However, many business owners mistakenly believe that once the project ends or the contract is terminated, their secrets remain permanently safe. Unfortunately, if your contract lacks a specific legal mechanism, those confidentiality obligations vanish the moment the agreement expires.

This is where a robust “survivability clause” becomes absolutely critical for Ontario businesses. 📈 This specific paragraph dictates exactly which promises continue to bind the parties long after the main commercial relationship has concluded. Without it, a former partner could legally use your customer lists or pricing strategies the day after your contract ends. If you are unsure whether your current contracts properly protect your intellectual property, we highly recommend searching our directory to find a skilled corporate lawyer who can review and strengthen your agreements.

Step-by-Step Process in Ontario

Drafting an enforceable survivability clause requires precision. Ontario courts generally dislike contracts that restrict business permanently unless there is a very good reason. Therefore, your clause must be reasonable, specific, and tailored to the exact type of information you are trying to protect.

Step 1: Categorize the Confidential Information

Your first step is to clearly define what information needs to survive the contract. 📂 Under Ontario common law, information is generally split into two categories: standard confidential information (like financial projections, marketing plans, and vendor lists) and strict trade secrets (like source code, chemical formulas, or unique manufacturing processes). Treating them differently in your survivability clause is legally essential.

Step 2: Establish Realistic Timeframes

You must assign a specific duration for the survival of the confidentiality obligations. For standard business information, Ontario courts typically uphold survival periods of 3 to 5 years after termination. This timeframe is generally considered reasonable because standard business data loses its competitive value over time. However, for true trade secrets, the clause should explicitly state that the obligation survives indefinitely, or for as long as the information legally remains a trade secret.

Step 3: Draft the Severability Language

Sometimes, a judge at the Superior Court of Justice might find one specific part of your NDA to be too restrictive. 📍 To prevent the entire agreement from being thrown out, you must include a severability clause alongside your survivability clause. This ensures that if the 5-year limit is deemed unreasonable, the court can strike it down while keeping the rest of the confidentiality protections firmly in place.

Step 4: Mandate the Return or Destruction of Materials

A survivability clause is much easier to enforce if the other party no longer holds your physical or digital documents. Your clause must specifically state that upon termination of the contract, the receiving party has a surviving obligation to immediately return, delete, or securely destroy all confidential materials, and provide a written certificate confirming they have done so.

Step 5: Define Post-Termination Remedies

Finally, your clause should outline what happens if someone breaches the agreement years after it ended. 💰 While you can always sue for financial damages, proving exact monetary losses can be difficult. Your survivability clause should state that a breach will cause “irreparable harm” and that you are entitled to seek immediate injunctive relief (a court order forcing them to stop using the information) in an Ontario court.

How Much Does it Cost in Ontario?

Protecting your company’s intellectual property requires a proactive financial investment, which is almost always cheaper than litigation.

  • Lawyer Drafting Fees: Having a business lawyer draft a customized NDA with a strong survivability clause typically costs between $300 and $800 CAD.
  • Contract Review: If you need a lawyer to review an NDA provided by another company, expect to pay a flat fee of $250 to $500 CAD.
  • Court Filing Fees: If a breach occurs and you must sue, issuing a standard Statement of Claim at the Superior Court of Justice costs $243.00 CAD.
  • Litigation Costs: Fighting a breach of confidentiality in court is highly complex and can easily cost $10,000 to $50,000+ CAD in legal fees.

How Long Does the Process Take?

Getting your contracts right does not have to slow down your business operations. ⏱ A competent corporate lawyer can usually draft a comprehensive NDA with custom survivability clauses in 1 to 2 weeks. Negotiating the terms with the other company typically adds another 1 to 3 weeks to the timeline. Once signed, the survivability clause activates upon termination and actively protects your information for the specified 3 to 5 years, or indefinitely for trade secrets. If you must go to court to enforce a breach, securing an emergency injunction can take a few days, but a full trial may take 2 to 3 years.

Frequently Asked Questions (FAQ)

Can I make standard confidential information survive indefinitely?

In Ontario, making standard business information survive indefinitely is highly risky. Courts may view it as an unreasonable restraint of trade and strike the entire clause down, leaving you with no protection. It is safer to use a 3 to 5 year limit.

Does a survivability clause cover my employees?

This depends on the contract. A commercial NDA is between businesses. To protect information from departing staff, you must include a survivability clause directly in their individual employment agreements.

What happens if I forget to include a survivability clause?

If the main contract expires and there is no survivability clause, the explicit contractual duty to keep information secret generally ends. However, you might still have a difficult and expensive claim under the common law tort of “breach of confidence.”

Can we enforce an Ontario NDA in another province?

Yes, but your contract should include a “Governing Law and Jurisdiction” clause stating that the agreement is governed by the laws of Ontario, and any disputes will be handled in Ontario courts.

What if the other company goes bankrupt?

If the receiving company files for bankruptcy, the survivability clause generally remains legally valid. However, practically speaking, recovering financial damages from an insolvent company is incredibly difficult, though you can still demand the destruction of your materials.
