Independent Contractor or Employee? Ontario’s Misclassification Risk Explained

You have three people who do work for your organization regularly. They invoice you monthly. They are not on payroll. You do not remit source deductions, pay vacation, or provide benefits. The arrangement has worked for years. You have contracts with each of them that describe the relationship as one of independent contractor and client.

The contract is not the determining factor. Ontario courts and the Canada Revenue Agency apply their own tests to determine whether a working relationship is one of employment or independent contracting, and those tests look at the substance of the relationship, not what the parties agreed to call it. If the substance of what your contractors do is indistinguishable from what your employees do, if you control their hours, direct their work, and integrate them into your operations, the legal characterization of the relationship follows the facts, not the document.

The Tests Courts Apply

Ontario courts assessing employment status follow the Supreme Court of Canada’s approach from 671122 Ontario Ltd. v. Sagaz Industries Canada Inc., 2001 SCC 59: ask the central question directly. Whose business is it? Is the worker operating a business for themselves, or are they performing services as an integral part of the organization they are working for?

The traditional four-factor test, control, ownership of tools, chance of profit, and risk of loss, remains relevant, but it is applied as part of a broader analysis rather than as a checklist. Control is the most significant factor. If the employer directs how the work is done, sets the hours, requires the worker to perform the services personally, and can discipline or remove the worker based on performance, those are features of an employment relationship. The fact that the worker does not receive benefits or that the invoice describes the payment as a fee for services does not change the underlying analysis.

Exclusive or near-exclusive work for a single client is another indicator that courts weight heavily. A genuine independent contractor operates a business that serves multiple clients. A worker who performs substantially all of their working time for one organization, at that organization’s direction, on that organization’s premises, looks a great deal more like an employee.

The CRA and the Employment Standards Exposure

The Canada Revenue Agency applies a similar analysis when auditing contractor arrangements. A CRA reassessment that concludes a worker was an employee requires the employer to remit all source deductions that should have been made, income tax, CPP, and EI, for the entire period of the relationship, plus interest and potentially penalties. Those amounts can be substantial for long-standing arrangements.

CRA audits are often triggered by a complaint from the worker. When the relationship ends, and independent contractor arrangements often end less cleanly than employment relationships, the worker may file a claim for EI benefits. Service Canada then makes a ruling on whether the person was insured, meaning an employee, or not. That ruling can trigger a broader CRA review.

Under the Employment Standards Act, if a worker is reclassified as an employee, their entitlements are calculated from the date the relationship began, not from the date of reclassification. Vacation pay, public holiday pay, overtime, and termination and severance entitlements all accrue retroactively. For a contractor who worked exclusively for one organization for five years at $80,000 annually, the retroactive vacation pay alone could be $16,000, before any termination or severance entitlements on the separation.

Why the Contracts Do Not Help

The standard independent contractor agreement disclaims the employment relationship in direct terms. Courts do not enforce those provisions if the working relationship is one of employment in substance. The Employment Standards Act cannot be contracted out of. The parties cannot agree, by contract, that employment standards obligations do not apply to what is, in fact, an employment relationship.

This means that an organization that has structured a contractor arrangement carefully, with a well-drafted agreement, can still be found to have employed the worker if the day-to-day reality of the relationship looks like employment. The document reflects the parties’ intentions. The courts and the CRA assess the reality.

The Honest Assessment

Contractor arrangements are commercially useful and entirely legitimate when the relationship is genuinely one of independent contracting. A consultant who operates a business, serves multiple clients, sets their own schedule, and works under their own direction is an independent contractor. The structure reflects the substance.

The problem is that many contractor arrangements in Ontario do not reflect that substance. They exist because the arrangement is administratively convenient, because the employer wants to avoid payroll obligations, or because the worker prefers the tax treatment of self-employment income. The legal risk attached to those arrangements sits with the employer.

If you have workers you are currently engaging as independent contractors, the question worth asking is whether the relationship would survive the scrutiny it will receive if the worker files for EI, if the CRA audits the arrangement, or if the worker decides at the end of the relationship to pursue the entitlements they would have had as an employee. Getting that answer before the relationship ends gives you options. Getting it after the claim is filed does not.
