Employees vs Contractors in Canada: Who Pays When the CRA Disagrees

Very few misclassified workers in Canada were hired that way on purpose. They were hired as contractors, by mutual agreement, often at the worker's request, with a signed contract that says exactly that.

The contract is not the deciding document. The CRA reads the working relationship, and it usually reads it long after the fact, once the engagement has ended and someone has asked a question that puts the relationship in front of a reviewer.

Here is the part that catches owners out. The worker wanted contractor status. The business pays for getting it wrong.

Quick answer: What is the difference between an employee and a contractor in Canada? The difference is the working relationship, not the paperwork. The CRA weighs who controls the work, who supplies the tools, who carries the chance of profit and the risk of loss, and whether the worker can send someone else in their place. What the two parties intended matters, but only where the day-to-day facts support it. If the CRA finds an employment relationship, the payer is assessed for the CPP contributions and EI premiums that should have been withheld, including the worker's share, plus penalties and interest compounded daily. A practical test: if the worker stopped tomorrow and applied for EI, would their description of how the work was done sound like an employee?

Contractors Are Not the Problem

Most Canadian businesses use contractors lawfully, and the arrangement is often the correct one. A specialist who works for six clients, sets their own schedule, brings their own equipment, and bids on defined projects is a contractor by any reading.

The exposure sits in a narrower place: the worker who started as a contractor and, over a year or two, quietly became something else. The hours firmed up. The other clients fell away. A company laptop appeared. Nobody revisited the arrangement, because the arrangement still had a contract behind it and the contract still said contractor.

Classification is not a decision made once at the start of an engagement. It is a description of how the work is actually performed, and it can drift while both parties are satisfied with it.

How the CRA Actually Decides

The CRA sets out its framework in guide RC4110, Employee or self-employed? Outside Quebec the analysis draws on common law and runs in two steps. First, what did the two parties intend the relationship to be. Second, does the working reality match that intent. Where the facts and the intent diverge, the facts govern. In Quebec the Civil Code of Québec applies instead, with subordination as the central question.

The factors under examination are ordinary and specific.

• Control. Who decides what gets done, when, where, and in what order. Points toward employment when the payer sets hours, assigns tasks, and supervises method.
• Tools and equipment. Who supplies and maintains what the work requires. Points toward employment when the payer provides the laptop, software licences, vehicle, or workspace.
• Subcontracting and helpers. Whether the worker can hire someone else to do the work. Points toward employment when the named individual must perform it personally.
• Chance of profit, risk of loss. Whether the worker can earn more through efficiency or lose money on a job. Points toward employment with fixed hourly or weekly pay, expenses reimbursed, and no capital at risk.
• Integration. Whose business the work forms part of. Points toward employment when the worker appears to clients as part of your team, with your email address.

No single factor decides it. A worker who supplies their own laptop is not a contractor on that basis alone, and one who works on your premises is not automatically an employee. The CRA weighs the picture, which is why two arrangements that look similar on paper can land on opposite sides.

Intent still carries weight, and a written agreement is worth having. It establishes what both parties understood at the outset. It just cannot survive a working relationship that contradicts it.

Who Gets the Bill

This is the asymmetry that surprises owners, and it is the reason worker classification is a payer's problem rather than a shared one.

When the CRA determines that a contractor was an employee, it assesses the payer for the CPP contributions and EI premiums that should have been withheld and remitted. Both shares. The employer's portion, which was always the employer's cost, and the worker's portion, which the employer never withheld and now generally cannot recover, because the worker left two years ago and was paid in full at the time.

On top of the contributions:

• A penalty for failing to deduct. Generally 10% of the amount that should have been withheld, rising to 20% for a repeat failure in the same calendar year made knowingly or in circumstances amounting to gross negligence.
• Late remitting penalties. Graduated by how late the remittance is, from 3% to 10%, with 20% for repeated gross negligence.
• Interest, compounded daily, from the date each remittance was due rather than from the date of the assessment. The same compounding mechanism that applies to a return filed late applies here, except that it runs from every missed remittance date rather than one filing deadline.
• Denied input tax credits. If the worker charged GST/HST on invoices and the business claimed ITCs on them, an employment finding undermines the basis for those claims.
• Personal liability for directors. Unremitted source deductions are trust funds. Under section 227.1 of the Income Tax Act and the parallel CPP and EI provisions, directors can be assessed personally where the corporation does not pay. Incorporation does not shield a director from this category of debt.

Income tax that should have been withheld is treated separately, and the outcome depends on what the worker already reported and paid. CPP and EI are the amounts that reliably stick.

There is also a second regulator with a different rulebook. Provincial employment standards apply their own test to the same relationship. A worker reclassified as an employee may have a claim for unpaid vacation pay, public holiday pay, and notice of termination, decided by the province rather than the CRA. Workplace safety insurance, WSIB in Ontario, runs its own coverage assessment as well. One arrangement, three sets of consequences.

Confirm current rates, penalty percentages, thresholds, and deadlines at canada.ca and with your provincial regulator before calculating against them.

How It Surfaces

Reclassification rarely begins with an audit of the business. It usually begins with the worker.

The engagement ends and the worker applies for EI. Service Canada needs to know whether the earnings were insurable, so the question goes to the CRA for a ruling. The worker describes how the work was done. That description, not the contract, is the evidence in front of the reviewer.

The worker requests a ruling directly. Either party can ask the CRA to rule on a worker's status using form CPT1. Workers do this when an engagement ends badly, or when the CRA questions the expenses claimed on their T2125 as a self-employed filer. The request is generally due by June 30 of the year following the year in question.

A PIER report. The CRA's Pensionable and Insurable Earnings Review compares the CPP and EI reported on your T4 slips against what the earnings should have produced. A deficiency generates a notice. This is routine processing rather than an audit, and it is one of the more common ways a payroll problem first arrives in writing.

A payroll examination. Where a business has employees already, contractor arrangements sitting alongside them are visible and get looked at.

Of those, the EI route is the one worth planning around. It is the most common by a wide margin, and it is the only one where you can predict the circumstances in advance: an engagement ends, and a worker who has been treated like staff for two years does what any departing employee would do.

The rest arrive without warning. What they have in common is that the trigger sits outside the business and fires after the relationship is over. By then the arrangement cannot be restructured. It can only be explained.

Five Signs a Contractor Is an Employee

• You set the hours. The workday has a start time you decided, and time off is requested rather than announced.
• They work on your equipment. Your laptop, your software licences, your desk, your vehicle.
• They cannot send a substitute. The engagement is with a person, not a capacity.
• They cannot lose money on the job. A fixed rate, expenses reimbursed, nothing of their own at risk in the outcome.
• You are effectively their only client. This is the one that changes without anyone deciding anything. The other work tapered off eighteen months ago, the invoices arrive on the same day each month, and neither of you has had a reason to mention it. It is also the factor a reviewer finds most persuasive, because it goes directly to whose business the work forms part of.

Two or three of these in one arrangement is common and worth reviewing. All five describe an employment relationship that has a contractor invoice attached to it.

What an Employee Costs Beyond the Salary

Owners hiring for the first time usually budget the wage and are then surprised by the rest. The salary is the largest line, not the only one.

• Employer CPP contribution. Matched to the employee's contribution on pensionable earnings above the basic exemption, plus the second CPP contribution on earnings above the first ceiling. Every pay period.
• Employer EI premium. 1.4 times the employee's premium on insurable earnings, to the annual maximum. Every pay period.
• Vacation pay. Provincial employment standards minimum, 4% of wages in Ontario and 6% after five years of service. Accrues from the first pay.
• Public holiday pay. Nine public holidays in Ontario, payable whether or not the employee works.
• Employer Health Tax (Ontario). Payroll above the annual exemption available to eligible private employers. Annually, with instalments once you cross the threshold.
• Workplace insurance premium. WSIB in Ontario, at the rate set for your industry classification. Every pay period.
• Termination notice or pay in lieu. Employment standards, scaled to length of service. At the end of the relationship.
• Administration. Payroll account registration, remittance on schedule, T4 slips, Record of Employment on departure. Ongoing, and at every interruption of earnings.

Statutory employer costs commonly add something in the range of 10% to 20% on top of salary, depending on province, wage level, and WSIB classification, before benefits or equipment. Rates and exemption thresholds change; confirm the current figures at canada.ca and with your province.

This also explains why a contractor's hourly rate is higher than an employee's hourly wage and why the comparison is not the saving it appears to be. A contractor's rate has to absorb both halves of CPP, unpaid time off, their own equipment, and the weeks between engagements. Choose the arrangement that matches the work. Choosing it to save payroll cost is the reasoning that produces the assessment.

If the Worker Is Incorporated

Bringing a corporation into the arrangement changes who carries the risk rather than removing it.

Where the payer contracts with an incorporated worker, CPP and EI obligations generally do not attach to the payer, because the payer is not paying an individual. The exposure moves to the worker's corporation under the personal services business rules. A PSB is, in substance, an incorporated employee: an individual providing services through a corporation who would reasonably be regarded as an officer or employee of the payer if the corporation did not exist.

The tax treatment is deliberately unattractive. A PSB is denied the small business deduction and the general rate reduction, faces an additional federal tax on its PSB income, and can deduct almost nothing beyond the salary and benefits paid to the incorporated employee. The ordinary corporate deductions are unavailable.

For a business engaging incorporated contractors, two things follow. Your direct payroll exposure is lower. Your contractor's exposure is higher than they may realize, and the same facts that would have made them your employee are what create it.

What to Do Before the First Pay Run

1. Decide the classification on the facts you intend to operate on, then run the relationship that way. An agreement describing an independent contractor, paired with a schedule you set and equipment you supply, is worse than no agreement at all, because it documents the divergence.
2. Request a ruling when the answer is genuinely unclear. Form CPT1 asks the CRA to determine a worker's status. It is worth far more before an engagement than after one has ended.
3. Open the payroll account before the first payment. An RP account under your business number.
4. Set the remittance frequency and put the dates in your fiscal calendar. Frequency is determined by your average monthly withholding amount and tightens as payroll grows. This one catches growing businesses more often than first-time employers, because nothing announces the change. You are simply on a faster schedule than you were, and the first indication is a late-remitting penalty on a payment you thought was early.
5. Diarize the annual obligations. T4 slips and the T4 Summary are due by the last day of February. A Record of Employment follows any interruption of earnings.
6. Review long-running contractor arrangements once a year. Classification drifts. The review costs an hour, sits naturally alongside a mid-year financial review, and is the only point in the cycle where a finding can still be acted on.

Frequently Asked Questions

Can I just write "independent contractor" in the contract?

You can, and you should have a written agreement, but it does not settle the question. The CRA applies a two-step analysis: what the parties intended, and whether the working relationship supports that intent. Where the facts contradict the document, the facts govern. A contract is useful evidence of intent and no protection against a relationship that operates as employment.

Who pays if the CRA reclassifies my contractor as an employee?

The payer. The CRA assesses the business for the CPP contributions and EI premiums that should have been withheld and remitted, including the worker's share, which is generally not recoverable from a worker who has already been paid in full and has often left. Penalties for failing to deduct and for late remitting apply on top, with interest compounded daily from each original due date. Where the corporation does not pay, directors can be assessed personally for unremitted source deductions.

How do I know whether a worker is an employee or a contractor in Canada?

Work through the CRA's factors in guide RC4110: control over how and when the work is done, ownership of tools and equipment, the chance of profit and risk of loss, whether the worker can subcontract or hire helpers, and how far the work is integrated into your business. Quebec applies the Civil Code of Québec, which centres on subordination. Where the answer is close, form CPT1 asks the CRA to rule on it.

What does hiring my first employee actually cost beyond the salary?

Employer CPP contributions, employer EI premiums at 1.4 times the employee rate, vacation pay accruing from the first pay, public holiday pay, workplace insurance premiums, and, above the exemption, Employer Health Tax in Ontario. Termination notice sits at the other end of the relationship. Statutory costs commonly add 10% to 20% on top of salary depending on province, wage level, and industry classification, before benefits or equipment. Confirm current rates at canada.ca and with your provincial regulator.

Do I have to issue a T4A to a contractor?

Fees for services paid to a contractor are reportable on a T4A slip, and the requirement is separate from the classification question. Issuing one does not make a worker a contractor, and it does not resolve the status of an arrangement that operates as employment. Confirm the current reporting requirements and thresholds at canada.ca.

What if my contractor is incorporated?

Contracting with a corporation generally moves CPP and EI obligations away from the payer, because the payment is not made to an individual. The risk lands on the worker's corporation instead, under the personal services business rules: no small business deduction, no general rate reduction, an additional federal tax on PSB income, and almost no deductible expenses beyond the salary paid to the incorporated employee. The facts that would have made the worker your employee are the same facts that make their corporation a PSB.

We have run this arrangement for three years. Is it too late to fix?

Restructuring the relationship going forward is always available and is worth doing as soon as the mismatch is identified. Prior years are a separate question that depends on the amounts, the periods still open, and how the arrangement is documented. It is a conversation to have with your accountant before the CRA opens it, because the options narrow considerably once a ruling request or a PIER notice has arrived.
