Employee vs. Independent Contractor: How the CRA Decides (and Why It Matters)
Calling someone a "contractor" instead of an "employee" doesn't make it so. The CRA uses specific criteria to determine how a working relationship should be classified — and if they disagree with yours, the consequences can be severe: retroactive CPP and EI contributions, plus interest and penalties going back years. Getting this classification right from day one protects both you and the person you're working with.
Why the Classification Matters So Much
The difference between employee and contractor isn't just a label — it determines who pays what to the government:
- Employees: You must withhold income tax, CPP, and EI from every paycheque. You remit both the employee's share and your matching employer's share of CPP and EI to the CRA. You must issue a T4 slip at year-end.
- Contractors: You pay the agreed amount, issue a T4A if they're unincorporated and paid over $500, and nothing more. The contractor handles their own taxes.
If you treat someone as a contractor but the CRA determines they were actually an employee, you can be assessed for all the CPP and EI that should have been remitted — both the employee's portion and your employer's matching portion — for the entire period. Add interest, and potentially a gross negligence penalty if the misclassification appears intentional.
How the CRA Determines the Classification
The CRA doesn't look at just one factor. They use a totality of the relationship test, weighing multiple factors together. No single factor is automatically decisive. The CRA's own publication RC4110 ("Employee or Self-Employed?") outlines the key considerations:
1. Control
Does the payer control how, when, and where the work is done — or just the final result?
You set the work hours, provide direction on how tasks should be completed, require the person to report to a specific location, and can redirect or prioritize their work at will.
The worker decides how to achieve the agreed result, sets their own schedule, works from their own location, and you don't supervise the day-to-day work.
2. Ownership of Tools and Equipment
Who provides the tools, equipment, and workspace?
You provide the computer, software, vehicle, workspace, and equipment. The worker uses your tools on your premises.
The worker uses their own tools, equipment, and software. They may work from their own office or home. They've invested in the tools of their trade.
3. Chance of Profit / Risk of Loss
Can the worker profit by working efficiently — or lose money if things go wrong?
The worker is paid a set wage regardless of the outcome. They have no financial risk if the project costs more than anticipated. They cannot sub-contract the work.
The worker can make more money by working efficiently. They bear the risk of cost overruns. They may have their own business expenses, may bid on contracts, and can sub-contract.
4. Integration (Whose Business Is It?)
Is this person's work integral to your core business operations, or are they an external service provider?
The work is central to your business operations. You couldn't function without people in this role. The worker doesn't offer similar services to other clients.
The worker has multiple clients and runs their own business. Their services are available to the market generally. Your business isn't dependent on this specific individual.
The Written Contract — Important, But Not Decisive
Having a written contract that calls someone a "contractor" helps, but it's not the end of the analysis. The CRA will look at the actual working relationship, not just the agreement on paper. If the reality of the arrangement looks like employment — you control their hours, they work exclusively for you, you provide all equipment — the CRA can override the contract.
That said, a well-drafted contractor agreement that reflects a genuinely independent relationship is important documentation. It should specify: the result expected (not the method), payment by project or milestone (not hourly wages like an employee), the worker's right to sub-contract, and their responsibility for their own taxes.
The Incorporated Contractor Question
If a worker is incorporated and provides services through their corporation, the employment relationship analysis still applies — but a finding of employment means the corporation is the "employer," not the individual. The CRA also watches for "personal services businesses" (PSBs) — incorporated workers who are really employees in disguise. If a PSB is found, the corporation loses most business deductions and faces higher tax rates.
When in doubt, ask the CRA. You can request a ruling on whether a specific working relationship is employment or self-employment using Form CPT1. The CRA will review the facts and issue a binding decision. This is especially useful for new, ongoing relationships where the classification isn't clear-cut.
What Happens If You Misclassify?
If the CRA determines a worker was an employee:
- You owe the employer's share of CPP and EI for the entire period — typically 5.95% CPP + 2.3% EI of the person's gross earnings
- You may also owe the worker's share if you can't recover it from them
- Interest accrues on the unpaid amounts from when they were due
- Penalties apply if the CRA determines the misclassification was not in good faith
- You must issue T4 slips retroactively
For a contractor paid $60,000/year over three years, the retroactive CPP and EI exposure (employer + employee portions combined) can easily exceed $25,000 before interest.
