Quick Answers

• “NDA” isn’t a catch-all. Confidentiality, client non-solicit, employee non-solicit and non-compete clauses do four different jobs, and courts treat them very differently.
• Non-competes rarely survive in Canada. In Ontario, they’ve been prohibited for most employees since October 2021.
• Client non-solicits can work, but only if they’re limited to the clients Bob actually worked with, time-limited, clearly defined and supported by consideration.
• Confidentiality clauses are the most enforceable, but they fail when they’re vague, when the information wasn’t treated as confidential, or when there’s no IP assignment clause.
• Courts don’t rewrite bad clauses. They strike them. Specificity, reasonableness, consideration and legal compliance decide what holds up.

Bob quit on a Friday.

By Monday he was working for your biggest competitor.

Your client list went with him. Your pricing models. The proposal template your team spent two years refining. The contacts he’d built on your dime, in your name, using your CRM.

You call your lawyer. We have an NDA. We have a non-compete. We have a non-solicit. We’re covered.

Your lawyer gets quiet.

“Let me take a look at what you actually signed.”

Three days later, you get the call. The non-compete is unenforceable. The NDA is too broad to rely on. The non-solicit might hold — but only partially, and only if you want to spend $40,000 finding out.

Bob’s six weeks into his new job. Your clients are fielding his calls.

You weren’t covered. You just thought you were.

That’s the expensive part.

 

Four Clauses. Four Different Jobs. One That’s Basically Useless.

Most employers use “NDA” as a catch-all for everything they want to protect.

It isn’t.

There are four distinct clauses, and courts treat them very differently:

• Non-Disclosure / Confidentiality clause — Bob can’t share your trade secrets, client data, pricing, or proprietary processes. During employment or after.
• Non-Solicitation of clients — Bob can’t call your clients and try to take them with him. He worked those relationships on your time.
• Non-Solicitation of employees — Bob can’t recruit your team on his way out. Or six months later when his new employer asks him to.
• Non-Compete clause — Bob can’t work for a competitor at all, within a defined geography and time period.

Four clauses. Four different jobs. And one of them almost never survives a courtroom.

 

Non-Competes: Assume They Don’t Work

Here’s the thing about non-competes in Canada.

Courts hate them.

Restraints on trade are presumptively unenforceable unless they’re reasonable in scope, geography, and duration — and “reasonable” is interpreted so narrowly it barely exists. A clause preventing a sales rep from working in the industry for 12 months across an entire province? Too broad. Any ambiguity in the wording? Interpreted against you. And if a non-solicit would have protected the same interest? Courts won’t enforce the non-compete on top of it.

Ontario went further: as of October 2021, non-compete clauses are prohibited for most employees under the Employment Standards Act. Not just unenforceable — illegal. Executives get a narrow carve-out. Everyone else: nothing.

But we’ve always had one in our contracts.

Doesn’t matter. If you’re in Ontario and your employee isn’t a C-suite executive, that clause is worth exactly nothing. And in other provinces, courts apply enough scrutiny that non-competes rarely survive anyway.

If your business continuity plan involves a non-compete holding up — you need a new plan.

 

Non-Solicitation of Clients: Can Work. Rarely Does.

Client non-solicits are a different story. Courts accept that you have a legitimate interest in the relationships Bob built on your behalf. He doesn’t get to monetize your clients for someone else the week after he quits.

But yours probably fails if:

• It covers every client Bob ever encountered, not just the ones he actually worked with
• There’s no time limit — two years is generally the outer limit courts accept
• “Solicitation” isn’t defined — if a client calls Bob at his new employer, is that solicitation? Your clause needs to answer that
• It was handed to an existing employee without a raise, bonus, or other fresh consideration — same problem that voids termination clauses, and it applies equally here

Courts don’t rewrite bad clauses. They strike them. One drafting failure and the whole thing goes.

 

Non-Solicitation of Employees: The One Nobody Thinks About

This one’s underrated.

Bob can’t call your team members and recruit them to his new employer. Courts recognize you have a real interest in the workforce you hired, trained, and developed.

Less scrutiny than client non-solicits. Far less than non-competes. A 12 to 24-month restriction with a clear definition of prohibited conduct has a genuine chance of holding up.

Same failure modes apply — too broad, no time limit, no consideration. But get this one right and it’s actually worth something.

 

NDAs: The One That Should Always Be There (But Usually Isn’t Done Right)

Confidentiality clauses are the most consistently enforceable of the four.

They also fail constantly.

A confidentiality clause prevents Bob from disclosing your trade secrets, client data, pricing, processes, or business strategies — during employment and after. In theory, airtight. In practice, it’s full of holes.

It fails when:

• The clause is too vague — “all confidential information” covers everything and therefore effectively covers nothing
• The information wasn’t actually treated as confidential — if your “confidential” pricing model was emailed around without any confidentiality notice, you’ve undermined your own claim
• There’s no IP assignment clause — a confidentiality clause says Bob can’t share what he created. An IP assignment clause says what he created belongs to you. You need both. Without it, there’s a real argument Bob owns the code he wrote, the designs he built, the content he produced.

Bob’s general skills and industry knowledge belong to him — even if he developed them on your payroll. You can protect your specific processes and data. You can’t protect his brain.

 

The Real Problem: You Thought You Were Protected

Here’s the version that actually hurts.

Not the employer with no protective clauses. The employer who has them, filed them away, told themselves they were covered — and found out they weren’t at the worst possible moment.

You made business decisions based on that protection. You didn’t think twice about what Bob had access to. You didn’t take steps to protect client relationships differently.

And now Bob has a six-week head start, your clients are taking his calls, and your lawyer is explaining why you’re looking at $40,000 in litigation with uncertain odds.

We have an NDA. We have a non-compete. We have a non-solicit.

You had paper. That’s different.

 

What Actually Holds Up

Four things determine whether your protective clauses survive:

• Specificity — define exactly what’s protected. Vague clauses lose.
• Reasonableness — scope, geography, and duration go no further than necessary. Courts won’t narrow an overbroad clause. They strike it.
• Consideration — signed before employment began, or with fresh value exchanged. No consideration, no enforceability.
• Legal compliance — non-competes for non-executives in Ontario are illegal. Using them anyway doesn’t just fail — it raises questions about the rest of your contract.

 

What Employers Ask

 

RascalHR Closes the Gaps

RascalHR employment contracts and NDA agreements are built to current Canadian law — including Ontario’s 2021 non-compete prohibition and the enforceability standards courts actually apply today.

Confidentiality clauses with defined categories of protected information. Client and employee non-solicits with reasonable time limits and clear scope. IP assignment language that establishes ownership of what your employees create. No non-compete clauses giving you false confidence while adding legal risk.

Province-specific. Case-law current. Updated as the law changes.

 

The Bottom Line

Non-competes: assume they don’t work. In Ontario, assume they’re illegal.

Non-solicits: can work — but only if they’re specific, reasonable, supported by consideration, and drafted to current standards.

NDAs: enforceable when they’re specific, when the information was actually treated as confidential, and when they’re paired with proper IP assignment.

The goal isn’t a contract that looks like it protects you.

It’s one that actually does.

Bob quit on a Friday. What happens Monday depends entirely on what you signed — and whether it holds up.
