Independent Contractor or Employee? The 2026 Misclassification Risk for Mississauga Employers

Two separate tests, same worker

When a Mississauga business engages a worker as an “independent contractor,” two entirely separate legal tests can be applied later — often at very different times — to challenge the classification.

The CRA test. The Canada Revenue Agency applies a two-step framework, described in publication RC4110, to determine whether a worker is an employee or self-employed for tax, CPP, and EI purposes. The first step asks what the parties intended when they entered the arrangement; the second step examines the substance of the relationship across several factors, including control, tools and equipment, chance of profit and risk of loss, integration into the business, and the ability to subcontract or hire helpers.

The ESA test. Ontario’s Employment Standards Act, 2000 establishes minimum standards for employees — hours of work, overtime, public holidays, vacation, and termination pay. Section 5.1 of the ESA prohibits treating an employee as if they were not one; the ESA definition of “employee” is broad and looks at the actual working relationship, not the label used in the agreement.

A third framework — the common-law test applied by Ontario courts — determines whether a worker is entitled to reasonable notice of termination, and can also produce a hybrid category called “dependent contractor” that carries entitlement to notice even without full employee status.

The factors that actually matter

The CRA’s two-step process asks first about the parties’ intent, then examines the substance of the relationship across several factors. The Supreme Court of Canada in 671122 Ontario Ltd. v. Sagaz Industries Canada Inc., 2001 SCC 59, framed the same inquiry as a single central question: whether the person who has been engaged to perform the services is performing them as a person in business on their own account. Justice Major noted that the list of relevant factors — control, ownership of tools, chance of profit, and risk of loss — is non-exhaustive, and that the relative weight of each factor depends on the particular facts.

In practice, the factors that most often decide the question in an SME context are:

• Who decides when, where, and how the work is done? Employees are told; contractors decide. Fixed daily schedules, mandatory meetings, and dress-code requirements point strongly toward employment.
• Tools and equipment. Who provides the laptop, phone, software, vehicle, and workspace? A worker who uses the payer’s equipment full-time looks more like an employee.
• Chance of profit and risk of loss. A true contractor can make more money by working efficiently, taking on additional clients, or absorbing losses on a bad job. An employee earns a fixed rate with no exposure to loss.
• Is the worker part of the day-to-day operation, indistinguishable from staff, or a separately branded service provider with their own clients?
• Subcontracting and helpers. A contractor can typically send someone else to do the work or hire helpers. An employee cannot.
• Duration and exclusivity. A multi-year engagement with a single payer, full-time, looks very different from a series of defined-scope engagements with several clients.

No one factor is decisive. The question is what the overall picture looks like — and the picture is what will be examined by CRA on audit or by the Ministry of Labour on an ESA claim, whatever the contract says on paper.

What is at stake if the classification is wrong

For a Mississauga employer, three separate categories of exposure follow a misclassification finding, and they can happen in any order:

CRA reassessment. If CRA determines the worker should have been treated as an employee, the payer becomes liable for the employer and employee portions of CPP and EI that were not remitted, plus unremitted income tax withholdings, plus interest and penalties. In some cases, the worker may be assessed as well for underpaid income tax on amounts already received.

ESA claims and back-pay orders. The Ontario Ministry of Labour can order the employer to pay minimum-standards entitlements that were not provided — unpaid overtime, public-holiday pay, vacation pay, and termination pay. The ESA also prohibits treating an employee as if they were not an employee (s. 5.1), and misclassification can trigger a Ministry investigation on a single worker’s complaint.

Common-law reasonable notice. If a “contractor” is later found by a court to have been an employee — or a dependent contractor — they may be entitled to reasonable notice of termination under the common law, which for a long-tenured older worker can easily reach 18 to 24 months of pay in lieu.

The combined exposure on a single misclassified relationship of five or more years can run into six figures, particularly where CPP, EI, income tax, ESA, and common-law claims stack together.

Common misclassification patterns in Mississauga SMEs

The patterns we see most often in Mississauga owner-managed businesses:

• The “long-term contractor.” A worker engaged as a contractor five years ago, full-time, with the payer’s email address, on the payer’s equipment, integrated into the team. The label on the invoices has not aged well.
• The single-client contractor. A worker who invoices only your business, has no other clients, and cannot practically take on others because of the hours they work for you.
• The “converted employee.” A former employee re-engaged as a contractor doing largely the same work, sometimes to reduce payroll burden. This one is watched closely by CRA.
• The commission-only sales rep. A worker paid entirely on commission but otherwise treated as staff — subject to schedules, meetings, and management direction.
• The “incorporated contractor.” A worker who has incorporated a personal services corporation, invoices through it, but works only for you. Incorporation does not by itself convert the relationship, and CRA has specific rules for personal services businesses.

A year-end review checklist for Mississauga employers

Before year-end, walk through this list with your corporate lawyer and payroll advisor for every contractor relationship you have:

1. List every worker classified as a contractor. Include personal-services corporations they invoice through.
2. For each, note tenure, hours per month, and whether they have other clients.
3. Confirm who owns the tools, software, and workspace they use.
4. Confirm how they are supervised — schedules, deliverables, mandatory meetings, reporting lines.
5. Confirm chance of profit and risk of loss — can they earn more by working harder, or lose money on a bad job?
6. Review their contract. Does it match the reality on the ground?
7. For anyone whose classification is uncertain, decide: convert to employment, restructure the relationship to look more like a true contractor arrangement, or apply for a CRA CPP/EI ruling to get certainty.
8. Document the review. A dated memo signed by the owner, describing the analysis for each worker, is worth keeping in the corporate records.

Frequently asked questions

Can we just call someone a contractor and have it stick?

No. The label in the agreement is one factor considered under intent, but both CRA and Ontario courts look at the substance of the working relationship. If the substance is employment, the label will not protect the classification.

What if the worker prefers to be treated as a contractor for tax reasons?

The worker’s preference is relevant to the intent analysis but does not decide the outcome. If CRA later determines the relationship was employment, the employer becomes liable for unremitted amounts regardless of what the worker preferred at the outset.

Does a personal services corporation change the answer?

Not necessarily. If a worker incorporates a personal services corporation and invoices through it, CRA still examines the relationship between the corporation and the payer, and may treat the corporation as a personal services business — a category that faces less favourable tax treatment. It also does not, on its own, defeat an ESA misclassification claim.

What happens if we get audited?

CRA will typically request contracts, invoices, communication with the worker, evidence of how the worker was supervised, and documentation of the workers’s other clients and business activities. The employer’s ability to demonstrate a coherent contractor relationship at the time — not a reconstruction after the fact — is what usually decides the outcome.

Can we ask CRA in advance whether a worker is an employee or contractor?

Yes. Either the payer or the worker can request a CPP/EI ruling from CRA. The ruling gives a determination of the worker’s employment status for CPP and EI purposes. It does not decide the ESA question or the common-law question, but it is a useful data point where the classification is uncertain.

How Mann Law helps

Mann Law advises Mississauga employers on the corporate and employment sides of contractor classification. Where a review of your workforce identifies uncertain cases, we work with you and your payroll advisor to decide whether to convert to employment, restructure the arrangement, or seek a CRA ruling. Where a contractor relationship is being ended, we can help you assess reasonable-notice exposure before the termination, not after.

A short classification review typically covers each of your contractor relationships, flags the ones that carry meaningful risk, and identifies a small number of concrete changes.
