The Canada Revenue Agency (CRA) looks at the real substance of your working relationship, not just what you and your employer call it. If you control how, when, and where you work, provide your own tools, set your own rates, and work for multiple clients, the CRA may view you as self-employed. Conversely, if your employer directs your work, provides equipment, sets your hours, and you work exclusively for them, you're likely considered an employee for tax purposes. This distinction matters because it changes how you file taxes, what deductions you can claim, and which benefits you can access. The CRA doesn't have a single checkbox list. Instead, they apply what's called the "four-in-one test" that looks at four key areas: Control: Who decides what work gets done, how it's done, and when? If your employer gives you detailed instructions and monitors your work closely, you're likely an employee. If you have freedom to decide how to complete projects, you may be self-employed. Ownership of tools: Do you own the equipment and tools needed for the job, or does your employer provide them? Self-employed people typically invest in their own resources.
Yes, employers can misclassify workers, but the CRA looks at the actual working conditions, not the label in a contract. If you work under an employer's direction, use their tools, and work exclusively for them, the CRA may reclassify you as an employee regardless of what your agreement says.
When a company claims someone is self-employed but controls when, where, and how they work (like a full-time on-site role with set hours and company equipment), that's a major warning sign. The CRA focuses on control and integration into the business.
Not necessarily. You can be an employee of multiple companies at once, each issuing you a T4. Self-employment involves more than just having multiple income sources; it requires you to be in business for yourself, managing your own clients and expenses.
You can request a status assessment from the CRA using their Employment Status Assessment Tool, or consult a tax professional. If the CRA disagrees with how you've been classified, you have the right to appeal their determination through the tax dispute process.
It depends on your income level and deductions. Self-employed people pay both employee and employer portions of CPP (higher contributions) but can claim more business expenses.
