How do I know if a worker is an employee or an independent contractor in Ontario?

The distinction between an employee and an independent contractor matters enormously in Ontario — it determines whether the worker is entitled to ESA protections, benefits, vacation pay, and notice on termination. It also affects HST obligations and payroll source deductions.

Ontario courts apply a multi-factor test that considers economic reality rather than just what the parties call the relationship. Key factors include: who controls how and when the work is done (control test), whether the worker supplies their own tools, whether the worker can profit or suffer loss from the arrangement, whether the worker works exclusively for one business, and whether the worker is economically dependent on this engagement.

Calling someone a "contractor" in a written agreement and issuing them a T4A instead of a T4 does not automatically make them a contractor. If the actual working relationship looks like employment — fixed hours, employer-supplied equipment, no ability to sub-contract, economic dependence — a court or employment standards officer may find they are an employee regardless of the label.

Misclassification can expose a business to back-pay of vacation pay, unpaid ESA entitlements, unremitted payroll deductions, and liability for wrongful dismissal. Getting the classification right at the start of the relationship is far cheaper than addressing it after a dispute.
