Employee vs Contractor: CRA Rules and Tax Implications

The Canada Revenue Agency uses several criteria to determine whether a worker is an employee or an independent contractor. The key factors include the degree of control the payer has over the work, whether the worker provides their own tools and equipment, the financial risk borne by the worker, and the ability to subcontract or hire helpers. If CRA determines that a worker has been misclassified as a contractor, the employer becomes liable for unpaid CPP contributions, EI premiums, income tax withholdings, plus penalties and interest—which can be significant.

From the employer’s perspective, hiring employees costs substantially more than the base salary. Employer-paid CPP contributions match the employee’s share (up to $4,056 each for 2026), EI premiums are 1.4 times the employee rate, and statutory obligations include vacation pay (minimum 4%), workplace safety insurance, and often extended health benefits. These overhead costs typically add 15%–25% on top of salary. Contractors absorb all these costs themselves, which is why a contractor charging 25%–40% more than an equivalent salary may still represent a comparable total cost to the business.

CRA Classification Criteria

Beyond cost, consider the strategic implications. Employees provide continuity, institutional knowledge, and are easier to manage. Contractors offer flexibility, specialized skills, and no long-term commitment. Many Canadian businesses use a hybrid model—core staff as employees with contractors for project-based or specialized work. If you are unsure about classification, CRA offers a ruling service through Form CPT1 that provides a binding determination.
