Temporary Workers vs Independent Contractors: Classification, Liability, and What Property Managers Need to Know

Worker classification in Canada is not a gray area. The Canada Revenue Agency, provincial employment standards boards, and workers' compensation bodies all have clear tests for distinguishing between an employee (including temporary employees) and an independent contractor. Getting it wrong is expensive.

In 2024, the CRA issued over $240 million in reassessments to Canadian businesses for worker misclassification. The penalties included unpaid CPP contributions, EI premiums, and income tax withholdings — plus interest retroactive to the start of the misclassified relationship.

If you use labor in your commercial facility — warehouse workers, cleaners, general laborers, event staff — this distinction affects you directly.

The Legal Test

The CRA uses a multi-factor test derived from case law (Wiebe Door Services Ltd. v. MNR, codified through subsequent Supreme Court decisions) that examines four primary factors:

1. Control

Employee/Temporary Worker: The business controls how, when, and where the work is done. The worker follows the business's processes, uses its tools, works its hours, and reports to its supervisors.

Independent Contractor: The contractor controls their own methods. They determine how to complete the work, set their own hours (within deadline constraints), and use their own tools and processes.

In a warehouse or commercial facility context: if you tell a worker to be at your dock at 7 AM, wear your safety vest, follow your loading process, and report to your shift supervisor — that person is an employee regardless of what the paperwork says.

2. Tools and Equipment

Employee: The business provides the tools, equipment, PPE, and materials needed to do the job.

Contractor: The contractor provides their own tools and equipment and is responsible for maintaining them.

3. Financial Risk

Employee: The worker is paid a fixed rate (hourly, daily, or salary) regardless of the business's profitability. The worker bears no financial risk from the engagement.

Contractor: The contractor bears financial risk — they may profit or lose money on a job. They invoice for completed work, have their own business expenses, and carry their own insurance.

4. Integration

Employee: The worker performs tasks that are integral to the business's operations. A warehouse picker in a distribution company is doing the core work of the business.

Contractor: The contractor provides a specialized service that is ancillary to the business's core operations. An electrician hired to install new lighting is providing a distinct service.

Where Businesses Get Into Trouble

The most common misclassification scenario in commercial facilities is this: a business needs extra labor, hires individuals through word of mouth or online platforms, pays them as "contractors" (no source deductions, no benefits, no WSIB coverage), but treats them as employees in every practical respect.

The workers show up at a set time. They use the company's equipment. They follow the company's processes. They report to the company's supervisor. They are paid by the hour. The only difference between them and the company's regular employees is the paperwork — and the CRA does not care about the paperwork. They care about the reality of the relationship.

The Real Costs of Misclassification

If the CRA reassesses a misclassified worker, the business owes:

• CPP employer and employee portions retroactive to the start of the relationship (currently 5.95% each on earnings up to $68,500 — total exposure of $8,151 per worker per year)
• EI employer and employee premiums retroactive (currently 2.282% employer, 1.63% employee)
• Interest on unpaid amounts at CRA's prescribed rate
• Potential penalties of 10% on first offense, 20% on subsequent offenses

For a business that has been using 10 "contractors" for 3 years at $20/hour full-time equivalent, the total reassessment exposure exceeds $250,000.

And that is just the CRA. Provincial workers' compensation boards (WSIB in Ontario, CNESST in Quebec, WorkSafeBC in BC) will independently assess unpaid premiums plus penalties for every worker who should have been covered. If one of those uncovered workers gets injured on your site, you are personally liable for the full cost of their claim — which can reach six or seven figures for a serious injury.

The Staffing Agency Solution

This is exactly why temporary staffing agencies exist. When you hire temporary workers through a licensed staffing agency:

• The agency is the employer of record. They handle all source deductions, CPP, EI, and income tax remittance.
• The agency carries WSIB/CNESST coverage. Every worker is covered from their first hour on your site.
• The agency handles employment standards compliance. Vacation pay, statutory holidays, termination notice — all managed by the agency.
• Your relationship with the worker is a commercial contract with the agency, not an employment relationship with the individual.

This does not mean you can treat agency workers as contractors. The legal relationship is: the worker is employed by the agency, and the agency provides you with labor services under a commercial agreement. The worker classification problem is solved because the worker is properly classified — as a temporary employee of the agency.

What to Verify With Your Staffing Agency

Not all staffing agencies operate at the same compliance level. Verify:

• WSIB/CNESST account in good standing. Request the account number and verify it directly with the provincial board. Some agencies let coverage lapse.
• Commercial general liability insurance. Minimum $2 million, ideally $5 million. Request a certificate of insurance naming your company as additional insured.
• Source deduction compliance. Ask for their most recent CRA payroll remittance confirmation. An agency that is behind on remittances is a risk to you.
• Employment standards compliance. Do they pay vacation pay on each cheque? Do they comply with statutory holiday requirements? Cutting corners here creates liability that can flow back to you as the client.

The Bottom Line for Facility Managers

If workers are performing labor at your facility on a regular or recurring basis, they need to be either your employees or temporary employees of a licensed staffing agency. The "independent contractor" classification is for genuinely independent businesses providing specialized services — plumbers, electricians, consultants — not for general labor.

The cost difference between using properly classified temporary workers and paying "contractors" under the table is approximately 25–35% (reflecting payroll taxes, WSIB premiums, and agency margin). The cost of a CRA reassessment plus WSIB penalties for getting it wrong is 200–400% of those savings. The math only works one way.
