Contractor vs. Employee: Worker Classification in Canada
How CRA determines if a worker is an employee or independent contractor — and the tax implications of getting it wrong.
Whether you're a business hiring talent or a professional taking on project work, getting the contractor-versus-employee classification right is critical under Canadian tax law. The CRA looks past your contract title to the real nature of the working relationship.
The CRA's Four-Factor Test
CRA evaluates each case using four common-law factors. No single factor decides it — the overall picture matters.
Control: Does the payer direct when, where, and how the work is done? A true contractor controls their own schedule and methods. Subordination: Is the worker integrated into the business or independently providing services?
Control, Ownership of Tools, Profit/Loss, and Integration
- Control — if the payer dictates hours, methods, and supervision, it points to employment. A contractor should have autonomy over how they complete deliverables.
- Ownership of Tools — a contractor supplies their own equipment (laptop, software, vehicle). An example: a delivery driver who owns their truck is more likely a contractor than one driving a company van.
- Profit/Loss — a contractor can earn a profit or suffer a loss based on how they manage expenses. An employee is guaranteed their wage regardless.
- Integration — if the worker's role is integral to the payer's core business, it leans toward employment. A bookkeeper handling all internal payroll is more integrated than one running a separate firm serving many clients.
Consequences of Misclassification
If CRA reclassifies a contractor as an employee, the payer becomes liable for unremitted CPP, EI, and income tax source deductions — plus penalties and interest. Back taxes can easily reach $10,000–$30,000 per worker per year.
The worker also loses the ability to deduct business expenses they claimed as a contractor, creating a double hit.
We had a BC construction company that paid five 'contractors' $80,000 each. CRA audited, reclassified all five, and assessed $48,000 in CPP/EI arrears plus $6,200 in penalties. A pre-engagement contract review would have caught the red flags.
CPP/EI Implications: T4 vs. T4A
- Employees get a T4 — employer pays half CPP (5.95%) plus EI (1.4x the employee premium). Contractors receive a T4A — no source deductions, but they pay both portions of CPP as self-employed.
- Employees are EI-eligible. Contractors generally are not, unless they opt into EI via a special agreement.
- Contractors can deduct home office, vehicle, and equipment expenses. Employees have much more limited deduction options.
Key Contracts to Have
A written contract is essential but not sufficient on its own — CRA will still look at actual working conditions. The contract should clearly state: no supervision on method, contractor provides own tools, freedom to subcontract, and bearing of financial risk.
For BC businesses, also check if WorkSafeBC coverage is needed. Contractors without their own coverage may trigger employer obligations under the Workers Compensation Act.
Key Takeaways
- 1CRA uses four factors — control, tools, profit/loss, integration — not just the contract title.
- 2Misclassification can cost $10,000+ per worker per year in back taxes, CPP, and EI.
- 3A T4A contractor is not EI-eligible and pays both sides of CPP.
- 4A written contract helps, but actual working conditions are what CRA audits.
- 5BC businesses should verify WorkSafeBC obligations separately.
