Employee or Independent Contractor?

The Label Doesn't Decide — the Substance Does

Calling a worker an 'independent contractor' in a contract does not make them one. Courts, tax authorities, and employment regulators in both Canada and the US look through the label to the substance of the relationship, weighing a set of factors: how much control the business exercises over how the work is done, who supplies the tools and equipment, whether the worker has a genuine chance of profit or risk of loss, and how integrated the work is into the business. Control is the most heavily weighted factor — a worker told when, where, and exactly how to work looks like an employee, while a contractor is engaged for a result and decides how to achieve it.

No single factor is decisive; the tests are holistic, which is precisely why the middle of the spectrum generates so many disputes. A written independent-contractor agreement does carry some weight and is worth having — it clarifies intent and allocates IP, taxes, and termination — but it cannot transform an employment relationship into contracting if the day-to-day reality is employment. The agreement and the actual practice have to match, or the substance wins.

The Tests Differ by Country, Agency, and State

In Canada, the leading framework comes from the Supreme Court's Sagaz and 671122 Ontario decisions, weighing control, ownership of tools, chance of profit, and risk of loss. Crucially, Canadian law recognizes a third category between employee and contractor: the dependent contractor — a self-employed worker who is economically dependent on a single client. Dependent contractors are entitled to reasonable notice of termination, sometimes approaching what an employee would receive, so a business that ends a long, exclusive 'contractor' relationship without notice can face a significant claim.

The US has no single test. The IRS applies a common-law control test for tax purposes; the Department of Labor uses an 'economic reality' test under the Fair Labor Standards Act for wage-and-hour questions; and states such as California apply the strict ABC test from Dynamex and AB 5, under which a worker is presumed an employee unless the hirer proves all three prongs — including that the work performed is outside the hirer's usual business. Because these tests differ, the same worker can be a contractor under one and an employee under another, so the analysis depends on which agency or law is asking.

Why Misclassification Is the Costliest Mistake

For businesses, treating an employee-like worker as a contractor is among the most expensive errors in this area. Exposure can include unpaid payroll taxes and source deductions, CPP/EI or FICA contributions, unpaid overtime, vacation and holiday pay, termination and severance liability, benefits, and penalties and interest — and tax authorities and labour boards can reassess years into the past. The savings from avoiding payroll obligations evaporate when a reassessment or a wrongful-dismissal claim lands, often at multiples of what compliance would have cost.

For workers, misclassification cuts the other way: someone treated as a contractor while functioning as an employee may be owed overtime, vacation and minimum-wage protections, and termination or severance notice — and in Canada, potentially reasonable notice as a dependent contractor. Either side can raise classification with the tax authority or employment regulator, and it frequently surfaces on termination. The practical takeaway is the same for everyone: assess the relationship honestly against the applicable test, make the working reality match the intended classification, and use a written agreement that reflects — rather than contradicts — how the work is actually done.
