If you’re running a business in Canada, you’ve probably hired people as contractors to save on payroll costs. Maybe you’ve even been told it’s a smart move. But here’s the thing: CRA doesn’t care what you call someone on paper. They care about the actual working relationship. And if they decide your “contractor” is really an employee, you’re on the hook for back CPP, back EI, penalties, and interest going back years.
I’ve seen this blow up on clients more than once. Someone hires a “contractor” who works full-time, uses company equipment, and takes direction from a manager. CRA takes one look and says “that’s an employee.” Suddenly you owe tens of thousands.

Why It Matters: The Real Cost of Getting It Wrong
When CRA reclassifies a contractor as an employee, here’s what happens:
- CPP: You owe both the employer AND employee share, going back up to 4 years. For someone earning $60,000, that’s roughly $7,700 per year in combined CPP.
- EI: Same deal. Employer and employee premiums, retroactively. Around $2,500/year combined.
- Interest and penalties: CRA charges interest on the unpaid amounts from the original due date, plus penalties for failing to withhold.
- T4 slips: You’ll need to issue corrected T4s for every year affected.
For a single worker over 3 years, a reclassification can easily cost $30,000 to $40,000 in back remittances, interest, and penalties. And that’s just one person.
How CRA Actually Decides: The Key Tests
CRA looks at the overall picture of the relationship. There’s no single factor that determines it. They weigh everything together.
Control
This is the biggest factor. Does the business control HOW the work gets done, or just WHAT gets done?
- Employee: You tell them when to work, how to do the job, and supervise their methods.
- Contractor: You define the end result. They decide how, when, and where to get it done.
Tools and Equipment
- Employee: The company provides the laptop, software, office space, and tools.
- Contractor: They bring their own equipment and cover their own costs.
Financial Risk
- Employee: Gets paid regardless of the outcome. No risk of financial loss.
- Contractor: Has a real opportunity for profit and a real risk of loss. They might have to redo work at their own expense.
Integration
- Employee: Their work is fully integrated into the business. They’re part of the team.
- Contractor: Provides services that are separate from the core business, or serves multiple clients.
Exclusivity
- Employee: Works only for you, full-time or close to it.
- Contractor: Serves multiple clients and is free to work for others.
The CRA Checklist: Red Flags That Scream “Employee”
If you check three or more of these boxes, you probably have an employee, not a contractor:
- They work set hours that you decide
- They work exclusively or primarily for you
- You provide their tools, equipment, or office space
- They’re on your benefits plan or get vacation pay
- You train them and supervise their methods
- They can’t hire helpers or subcontract the work
- They don’t invoice you, they just get paid on a schedule
- They’ve been working for you for years without a break
What About the Contract? Doesn’t That Prove It?
Having a contract that says “independent contractor” helps, but it’s not enough on its own. CRA looks at the actual working relationship, not what the paperwork says. If the day-to-day reality looks like employment, the contract won’t save you.
That said, you should still have a proper written agreement. It should clearly define the scope of work, payment terms, who provides tools, and the fact that the contractor is responsible for their own taxes and remittances. A good contract doesn’t guarantee protection, but not having one almost guarantees trouble.
If You’re Unsure, Ask CRA for a Ruling
CRA has a formal process for this. Either the business or the worker can submit Form CPT1 to request a ruling on employment status for CPP and EI purposes.
It takes a few weeks to get an answer, but it gives you certainty. And honestly, getting a ruling BEFORE there’s a problem is always better than finding out during an audit.
Tax Differences Between Contractors and Employees
| Factor | Employee | Contractor |
| Income reported on | T4 slip | Invoice / T4A if over $500 |
| Tax withholding | Employer deducts at source | Contractor pays own installments |
| CPP | Split employer/employee | Self-employed rate (both halves) |
| EI | Required | Not required (optional) |
| GST/HST | Not applicable | Must charge if over $30K revenue |
| Expense deductions | Limited (T2200 required) | Full business expense claims |
| Home office | Need employer sign-off | Claim directly on T2125 |
Frequently Asked Questions
What’s the difference between an independent contractor and an employee in Canada?
The main difference comes down to control. An employee works under the direction of the employer, uses company tools, and has set hours. A contractor controls how they do the work, uses their own equipment, takes on financial risk, and typically serves multiple clients. CRA looks at the full picture, not just what the contract says.
Can CRA reclassify a contractor as an employee?
Yes, and it happens more than you’d think. If CRA determines the working relationship looks like employment, they can reclassify the worker retroactively. The employer then owes back CPP, EI, penalties, and interest. This is a top audit trigger, especially for businesses with long-term “contractors” who work exclusively for one company.
What happens if I’ve been paying someone as a contractor and they’re really an employee?
You’ll owe both the employer and employee shares of CPP and EI retroactively (up to 4 years), plus interest and penalties. You’ll also need to issue T4 slips for the affected years. In my experience, this usually comes up during a payroll audit, and the amounts add up fast.

Don’t Guess on This One
Worker classification isn’t something to figure out on your own. The penalties for getting it wrong are steep and they go backwards. If you’re hiring people and you’re not sure whether they should be contractors or employees, talk to us before you set up the arrangement. It’s way cheaper to get it right upfront than to fix it after CRA comes knocking.
