Ontario business owners increasingly rely on NDAs because the Working for Workers Act, 2021 banned most non-compete clauses. That makes a properly drafted confidentiality agreement the primary tool for protecting trade secrets, client lists, financial data, and proprietary technology when you share information with employees, contractors, investors, or potential partners.

Generic templates from the internet are typically based on US law and rarely hold up in Ontario courts. A poorly drafted NDA can be struck down for being overly broad, lacking consideration, or missing required elements. We draft custom NDAs that are calibrated to your actual business risk and enforceable under Ontario law.

Common NDA Situations We Handle

Investor NDA

Sharing your pitch deck or business plan with investors

When you're raising capital and need to share financial projections, customer data, proprietary technology, or strategic plans, an NDA can protect that information from being used against you. Common with angel investors, strategic partners, family offices, and corporate development teams who are evaluating your business.

We draft investor NDAs that protect your information without being so aggressive they discourage the conversation — a frequent problem with template NDAs that founders pull off the internet.

Honest note on top-tier VCs: Most institutional VCs will not sign an NDA, as a matter of policy. We'll help you figure out what's realistic for your stage and audience — staged disclosure, redacted materials, or relying on contractual confidentiality inside the term sheet — instead of pushing an NDA that gets you ignored.

Employee NDA

Hiring employees with access to confidential information

Because Ontario banned non-compete clauses in 2021 under the Working for Workers Act, the NDA is now your primary protection against information leaving with departing employees. That makes the drafting standard higher than it used to be — generic templates that worked when you also had a non-compete are no longer enough on their own.

We draft employee NDAs that are calibrated to your actual trade secrets and confidential information, set reasonable post-employment restrictions on use, and pair cleanly with the rest of your employment documents (offer letter, IP assignment, handbook).

Contractor NDA

Engaging freelancers, agencies, or contractors

When you bring on a contractor, freelancer, or agency that will see confidential information — source code, client data, designs, financial projections — they need a stronger contractual structure than an employee. Contractor NDAs need to address what they can do with the information during and after the engagement.

Important: contractor NDAs should usually be paired with IP assignment language. Unlike employees, contractors don't automatically assign their work product to you — they own it unless your contract says otherwise. Most off-the-shelf NDA templates miss this entirely.

M&A / Due Diligence NDA

M&A, due diligence, and strategic transaction NDAs

When you're exploring a sale, acquisition, joint venture, or significant strategic partnership, the NDA is the first document exchanged — and it sets the tone for everything that follows. M&A NDAs are typically more complex than standard NDAs: they involve multiple categories of information, extended duration, non-solicit considerations, and standstill or no-shop provisions in some cases.

We scope M&A and due diligence NDAs on the consultation call because the right structure depends on whether you're the buy-side or sell-side, what kind of process is running, and the counterparty's sophistication.

NDA Review

When you've been asked to sign an NDA

If someone has handed you an NDA to sign — a prospective employer, a larger company you want to do business with, a counterparty in a deal — don't sign blind. NDAs are often more aggressive than they need to be, and once signed, the obligations can follow you for years.

We review NDAs and return a plain-English summary of what you're agreeing to, identify overbroad or unenforceable clauses, flag terms that conflict with your other obligations (employment, prior NDAs, fiduciary duties), and recommend specific redlines or negotiation points. You leave knowing exactly what you'd be signing, and where the leverage is.

Unilateral or mutual? A unilateral (one-way) NDA is right when only one party is sharing confidential information — you to an investor, you to a contractor. A mutual NDA fits when both parties are sharing — joint ventures, partnerships, vendor evaluations. The right structure is decided on the scoping call.

Common NDA Mistakes That Void Enforceability

These are the mistakes Ontario courts have repeatedly used to strike down NDAs. Most of them appear in template NDAs pulled from the internet — including the ones marked “Canadian.”

Vague "any business information" definitions

Catch-all definitions like "any and all information of a confidential nature" are routinely struck down. Ontario courts want to see specific categories — trade secrets, client lists, financial data, product roadmaps — tied to your actual business.

Perpetual restrictions on non-trade-secret information

Forever is not a duration a court will enforce. Reasonable durations vary by category — trade secrets can be perpetual; ordinary business information typically gets 2–5 years. NDAs that try to lock everything down forever lose the whole agreement.

Missing whistleblower and legal-disclosure carve-outs

An NDA that prevents reporting illegal conduct, harassment, or human rights violations is unenforceable in Ontario — and including overbroad restrictions can put the entire agreement at risk. Required carve-outs are legal disclosure, whistleblowing, and information already public.

US-jurisdiction governing law clauses

Templates pulled from US sources usually default to a US state's law and court system. When a dispute happens, you find yourself trying to litigate in Delaware. Ontario-governed agreements with proper forum-selection clauses keep disputes manageable.

Every clause we draft is calibrated to your business — not pulled from a template.

What Goes Into an Enforceable Ontario NDA

An NDA is only as good as its enforceability. Ontario courts have consistently upheld well-drafted NDAs — and just as consistently struck down NDAs that overreach. When we draft your NDA, we work through each of these elements deliberately:

  • A clear definition of “Confidential Information.” Vague definitions are why most NDAs fail in Ontario courts. We tie the definition to your actual business categories.
  • Reasonable duration. Trade secrets can be perpetual; ordinary business information typically gets 2–5 years. Forever-restrictions on non-trade-secret information are routinely struck down.
  • Reasonable scope. Restrictions on use of information, not just disclosure — and tied to a permitted purpose, so the receiving party knows what they're allowed to do with it.
  • Required carve-outs. Publicly available information, independently developed information, lawfully received from a third party, and disclosure required by law.
  • Whistleblower & legal-disclosure protection. NDAs cannot prevent reporting illegal conduct, harassment, or human rights violations — and including overbroad restrictions puts the whole agreement at risk.
  • Choice of law and jurisdiction. Ontario law, Ontario courts. Disputes shouldn't end up in Delaware.
  • Remedies clause. Injunctive relief is critical — money damages are often inadequate when the harm is a confidentiality breach.

Every clause is calibrated to your business — not pulled from a template.

NDA Questions, Answered

The questions Toronto founders and business owners ask most often.

Technically no — but most online templates are based on US law and may not be enforceable in Ontario. A lawyer-drafted NDA addresses the specific elements Ontario courts look for: precise definition of confidential information, reasonable scope and duration, valid consideration, and required carve-outs.
You can, but it carries real risk. Common failure modes in templates: vague definition of "Confidential Information," overbroad scope, missing whistleblower carve-out, no proper consideration for non-employees, and US-based governing law clauses that don't fit an Ontario dispute.
Functionally the same in Ontario. The terms are used interchangeably — same legal effect.
Yes, when properly drafted. Ontario courts have struck down NDAs that are overly broad, lack proper consideration, or attempt to prevent lawful activities like whistleblowing or reporting illegal conduct.
Unilateral when only one party shares confidential information (you to an investor, you to a contractor). Mutual when both parties share (joint ventures, partnerships, M&A discussions). The right structure is determined on the scoping call.
Common with VCs and large enterprises. We can advise on alternatives — staged disclosure, redacted materials, or relying on contractual confidentiality clauses inside the larger transaction agreement.
No. NDAs in Ontario cannot prevent whistleblowing, reporting crimes, harassment, or human rights violations. Any clause attempting to do so is unenforceable, and including overbroad restrictions can put the entire agreement at risk.
The narrower and more specific the better. Vague catch-all definitions ("any business information") tend to be struck down. We help you identify the actual categories — trade secrets, client data, financial information, proprietary processes, IP — and draft definitions that hold up.
