Employee vs. Contractor in Canada: How Misclassification Exposes Your Startup

Why Classification Matters More Than You Think

The distinction between employee and independent contractor is one of the most consequential legal determinations a Canadian startup will face. Get it wrong, and you are exposed on every front simultaneously: retroactive Canada Pension Plan (CPP) and Employment Insurance (EI) contributions, unpaid income tax withholdings, penalties and interest from the Canada Revenue Agency (CRA), wrongful dismissal liability under common law, and entitlements under provincial employment standards legislation that you never budgeted for.

The CRA does not care what your contract says. Neither do the courts. The label the parties attach to the relationship is a relevant factor, but it is far from determinative. What matters is the substance of the working arrangement — and Canadian law has developed a multi-factor test that looks at the real-world dynamics of the relationship, not the paperwork.

The Sagaz Test: The Supreme Court Framework

The leading authority on worker classification in Canada is 671122 Ontario Ltd v. Sagaz Industries Canada Inc., [2001] 2 SCR 983, where the Supreme Court of Canada synthesized decades of case law into a central question: whose business is it?

The Court adopted the four-factor test from Wiebe Door Services Ltd v. MNR, [1986] 3 FC 553 (FCA), which considers:

• Control: Does the payer control not just what work is done, but how, when, and where it is done? The more control the payer exercises, the more the relationship looks like employment.
• Ownership of tools: Does the worker provide their own equipment, software, and workspace? Employees typically use the employer's tools; independent contractors bring their own.
• Chance of profit: Can the worker increase their income by working more efficiently or taking on additional clients? Employees earn a fixed salary; independent contractors bear the economic risk and reward of their own business decisions.
• Risk of loss: Does the worker bear financial risk — liability for deficient work, unpaid invoices from their own clients, or the cost of redoing unsatisfactory work? An employee bears no risk of loss; they get paid regardless of the employer's profitability.

No single factor is decisive. The Court in Sagaz emphasized that the central question is whether the worker is performing services as a person in business on their own account.

The Dependent Contractor: The Category That Catches Startups

Canadian law recognizes a third category that does not exist in most other jurisdictions: the dependent contractor. A dependent contractor is a worker who is technically self-employed — they may have a business number, invoice for their services, and work under a contractor agreement — but who is economically dependent on a single client for all or substantially all of their income.

The Ontario Court of Appeal in McKee v. Reid's Heritage Homes Ltd., 2009 ONCA 916, confirmed that dependent contractors are entitled to reasonable notice of termination, just like employees. The notice period is assessed using the same Bardal factors that apply to employees: age, length of service, character of employment, and availability of similar employment.

This is the classification that catches most startups. You hire a "contractor" who works exclusively for your company, uses your Slack, attends your stand-ups, and has no other clients. When you terminate the relationship, they are entitled to reasonable notice — which, depending on the length of the relationship, could be months of compensation you never anticipated.

The CRA's Administrative Approach

The CRA uses its own variant of the Wiebe Door factors when assessing employment status for CPP, EI, and income tax purposes. If the CRA determines that a worker you classified as a contractor was actually an employee, the consequences are immediate and retroactive:

• Employer's share of CPP contributions for the entire period of misclassification
• Employer's EI premiums for the entire period
• Penalties of up to 10% of the amounts owing for repeat non-compliance
• Interest on all outstanding amounts

The worker may also be entitled to reassessment of their personal income tax, and the CRA will look to the employer to remit the withholdings that should have been deducted at source.

How to Structure Each Relationship Correctly

If the Worker Is an Employee

Use a proper employment agreement that complies with current post-Waksdale standards. Include enforceable termination provisions that track the Employment Standards Act minimums, a clear IP assignment clause (because the Copyright Act s.13(3) only covers work created in the course of employment, and does not cover patents or trade secrets), and any restrictive covenants that comply with the Shafron v. KRG Insurance framework for reasonableness.

If the Worker Is Truly Independent

Structure the relationship to satisfy the Sagaz factors. The contractor should have multiple clients, provide their own tools, set their own hours, bear financial risk, and have the ability to profit from efficiency. The contract should reflect these realities — not just recite them. Courts look at substance, not boilerplate.

Critically, the contractor should provide services through their own incorporated entity where possible, issue invoices with GST/HST, and maintain their own business insurance. These are not just formalities — they are evidence that supports independent contractor status.

If the Worker Falls in the Middle

If the reality of the relationship is economic dependence — one client, integrated into the company's operations, no real ability to profit independently — then you have a dependent contractor. The safest approach is to treat them as an employee for all practical purposes, or to genuinely restructure the relationship so they have multiple clients and real economic independence.

The Practical Takeaway

Misclassification is not a technicality. It is a material financial and legal risk that compounds over time. Every month of misclassification increases the retroactive liability, and the CRA's enforcement posture has become significantly more active in recent years, particularly for technology companies that rely heavily on contractor relationships.

Before you issue that next contractor agreement, ask yourself the Sagaz question honestly: whose business is it? If the answer is "ours," the worker is an employee — and your agreements need to reflect that reality.
