Whether a worker is an "employee" or an "independent contractor" sounds like a label the parties can simply agree on. For tax purposes, it isn't. The CRA — and the courts, when a case gets that far — look past whatever the contract calls the relationship and examine how the work actually happens. Getting this classification wrong exposes the business, and sometimes the worker, to a reassessment years after the fact.
This article explains the CRA employee or contractor test: the factors CRA actually weighs, and why the label in a written agreement is only one small piece of the picture.
Why This Classification Matters
If a worker is genuinely an employee, the payer is responsible for withholding and remitting income tax, CPP, and EI from that worker's pay. If a worker is genuinely an independent contractor, none of that applies — the contractor handles their own remittances and can generally deduct business expenses the way an employee can't. Calling an employee a "contractor" to avoid the withholding obligation is one of the more common issues the CRA reassesses.
The Contract's Label Isn't the Answer
A written agreement that calls someone an "independent contractor," or that both parties genuinely intended a contractor relationship, is a relevant piece of evidence — but it isn't determinative. CRA and the courts look at the substance of the working relationship, not the label the parties chose. A worker can be functioning as an employee in every practical sense even if their contract says otherwise, and the reverse is also possible.
The Factors CRA Actually Weighs
| Factor | What CRA Looks At |
|---|---|
| Control | Who decides how, when, and where the work gets done — the payer directing the details points toward employment; the worker controlling their own methods points toward a contractor relationship |
| Ownership of tools and equipment | Whether the worker supplies their own tools, equipment, or workspace, or uses the payer's |
| Chance of profit / risk of loss | Whether the worker can increase their earnings through their own business decisions, and bear a genuine risk of loss, the way a business owner would, versus being paid a fixed amount regardless of outcome |
| Integration into the business | Whether the work is a core, ongoing part of the payer's operations that looks like it's being done by staff, versus a discrete project delivered by an outside business |
This four-factor approach comes from CRA's own guidance, CRA Guide RC4110, and reflects how the courts have approached the question. No single factor is automatically decisive — CRA weighs them together based on the facts of the actual working relationship.
How CRA Puts It All Together
There's no fixed formula or point score. CRA — and a court, if the matter is disputed — looks at the whole relationship and asks whether the worker is genuinely in business for themselves, or is economically dependent on and integrated into the payer's business the way an employee would be. A worker who ticks most of the "contractor" boxes on paper but is, in practice, closely directed and fully integrated into the payer's operations can still be found to be an employee.
Not the Same Question as Employment Standards
It's worth keeping this test distinct from the analysis used under Ontario's employment standards legislation, which governs things like minimum wage, vacation pay, and termination entitlements. A worker's status under employment standards law and their status for CRA source-deduction purposes are assessed under related but separate frameworks, and a conclusion under one doesn't automatically decide the other.
Frequently asked questions
Can a worker ask CRA to formally decide their status?
Yes. A worker or a payer can ask CRA for a ruling on CPP and EI status for a specific working relationship, and CRA will apply this same substance-over-form analysis to make a determination.
If I've always called my worker a "contractor" and they agreed, does that protect the business?
Not on its own. Mutual agreement on the label is a factor CRA and the courts consider, but it doesn't override the substance of the relationship if the facts point the other way.
Does having a written independent contractor agreement help at all?
It can be useful supporting evidence, especially if the agreement's terms actually reflect how the work is carried out in practice. It carries much less weight if daily reality contradicts what the contract says.
What if the worker operates through their own corporation?
Incorporating changes some of the analysis, but it doesn't automatically settle the question — a separate CRA rule, the "personal services business" rule, can still apply if the underlying relationship still looks like employment.
