The Sagaz Test Explained: How Canadian Courts Classify Your Workers

The Central Question: Whose Business Is It?

The Supreme Court of Canada's 2001 decision in 671122 Ontario Ltd v. Sagaz Industries Canada Inc., [2001] 2 SCR 983, remains the definitive framework for classifying workers in Canada. The decision did not create new law — it synthesized decades of jurisprudence into a unified test that Canadian courts, tribunals, and the Canada Revenue Agency have applied consistently for over two decades.

The central inquiry is deceptively simple: is the worker performing services as a person in business on their own account, or as part of the payer's business? The answer determines everything — employment standards entitlements, wrongful dismissal liability, CPP and EI obligations, income tax withholding, workers' compensation coverage, and human rights protections.

The Four Wiebe Door Factors

In Sagaz, the Supreme Court adopted the four-factor test from Wiebe Door Services Ltd v. MNR, [1986] 3 FC 553 (FCA), while emphasizing that no single factor is determinative and that the overall relationship must be considered holistically.

Factor 1: Control

Control is consistently the most important factor in the analysis. The question is not whether the payer exercises day-to-day control over the worker, but whether the payer has the right to control how, when, and where the work is performed.

Indicators of employment:

• The payer sets working hours, deadlines, and schedules
• The payer directs the method of performing the work, not just the result
• The worker reports to a manager and participates in company meetings
• The payer provides training and onboarding
• The worker must seek approval before taking on other work

Indicators of independent contractor status:

• The worker determines their own schedule and method of work
• The payer specifies the desired result but not the process
• The worker is free to take on other clients simultaneously
• The worker does not attend company meetings or follow internal processes

For tech startups, the control factor is where classification most often fails. A "contractor" who attends daily stand-ups, uses your project management tools, follows your sprint cycle, and has their work reviewed by your engineering lead is being controlled like an employee — regardless of what the contract says.

Factor 2: Ownership of Tools

Does the worker provide their own equipment, software, and workspace? In knowledge-work contexts, "tools" includes computer hardware, software licences, development environments, and physical workspace.

A contractor who uses their own laptop, their own IDE, their own cloud services, and works from their own office looks more independent than one who uses company-provided equipment, company Slack, company GitHub, and company-provided software licences. The more of the working environment the payer provides, the more the relationship resembles employment.

Factor 3: Chance of Profit

Can the worker increase their income by working more efficiently, managing their time better, or taking on additional work? An employee earns a fixed salary regardless of efficiency. An independent contractor can profit by completing work faster (allowing them to take on additional clients) or by managing their business more effectively.

A "contractor" who is paid a fixed monthly retainer, works exclusively for one client, and has no opportunity to profit from efficiency is economically indistinguishable from an employee.

Factor 4: Risk of Loss

Does the worker bear financial risk? This includes the risk of non-payment by their own clients, the cost of redoing unsatisfactory work, liability for errors and omissions, and the overhead costs of running their own business (insurance, office space, equipment maintenance).

An employee bears no risk of loss — they get paid regardless of the employer's profitability, and they are not liable for the cost of their own mistakes. An independent contractor bears real financial risk: they invoice for their work (with the risk of non-payment), they carry their own insurance, and they bear the cost of correcting deficiencies.

The Integration Test

Beyond the four Wiebe Door factors, Sagaz also considered the "integration" or "organization" test: is the worker integrated into the payer's business, or do they operate as an independent business that provides services to the payer? This is an overarching assessment that considers the totality of the relationship.

Indicators of integration include: the worker has a company email address, appears on the company's website, attends company social events, is included in company communications, and is perceived by third parties as part of the company's team. Each of these factors — while not determinative individually — contributes to the overall picture of integration.

The Dependent Contractor: Canada's Third Category

Canadian employment law recognizes three categories of worker: employee, independent contractor, and dependent contractor. The dependent contractor category, confirmed by the Ontario Court of Appeal in McKee v. Reid's Heritage Homes Ltd., 2009 ONCA 916, applies to workers who are technically self-employed but economically dependent on a single payer for all or substantially all of their income.

A dependent contractor is not entitled to the protections of employment standards legislation (those are reserved for employees). However, they are entitled to reasonable notice of termination under the common law — the same Bardal factors analysis that applies to employees. This means that terminating a dependent contractor without reasonable notice exposes the payer to the same type of wrongful dismissal claim that an employee could bring.

The hallmarks of dependent contractor status include:

• Economic dependence on a single client for all or substantially all income
• Exclusivity — the worker does not have other clients
• A long-standing relationship (years, not months)
• Integration into the payer's operations

What the CRA Looks At

The CRA conducts its own classification analysis for CPP, EI, and income tax purposes. While the CRA applies the same Wiebe Door factors, its administrative approach places particular emphasis on the parties' intention (what did they intend the relationship to be?) and the degree of control exercised by the payer.

If the CRA determines that a worker classified as a contractor was actually an employee, the employer faces retroactive CPP contributions (both employer and employee shares), retroactive EI premiums, penalties, and interest — potentially for every year the relationship existed.

Structuring the Relationship Correctly

The Sagaz test looks at substance, not form. A well-drafted contractor agreement helps, but it does not override the reality of the relationship. If you want the relationship to be genuinely independent, you need to structure the working arrangement — not just the paperwork — to reflect independence: multiple clients, worker-provided tools, project-based deliverables, no day-to-day control, and real financial risk.

If the working arrangement looks like employment, call it employment. The cost of proper classification upfront is always less than the cost of retroactive reclassification.
