You bring in a designer to handle your marketing, you pay their invoices for a year, and everyone calls it a contract. Then the CRA reviews the arrangement and decides that designer was your employee all along. You now owe the employer’s share of CPP and EI going back to day one, plus penalties and interest. The designer gets an EI eligibility mess they never asked for. Nobody wins.
Whether someone counts as a contractor or an employee in Canada is not your call, and it is not the worker’s either. The CRA decides, using its own contractor vs employee rules. A clause in your contract that says “independent contractor” helps, but it does not settle the question. Here is how the CRA actually makes the call, and how to protect yourself before it does.
Why the label matters
An employee triggers a payroll obligation. You withhold income tax, CPP and EI at source, remit them monthly, and issue a T4 slip. The worker gets EI coverage and CPP credits without lifting a finger.
A contractor handles their own tax affairs. You pay the invoice and issue a T4A if required. They pay both halves of CPP, make quarterly instalment payments on their income tax, and get no EI coverage unless they opt in voluntarily. On the upside, they can deduct legitimate business expenses against their income, which employees generally cannot.
Get the classification wrong and the CRA can reassess you retroactively: back CPP and EI contributions, interest from the original due dates, and penalties. That is the expensive part. The awkward part is telling a long-standing “contractor” they were legally your employee.
Contractor vs employee: the CRA rules behind the decision
The CRA uses what it calls the total relationship approach. It is a two-step test, set out in the CRA’s own guide on the topic (Guide RC4110, Employee or Self-Employed?).
Step one: what did the parties intend? The CRA looks at the contract and what both sides say the arrangement was. Step two, and this is the one that matters: does the way the work actually happens match that intention? The CRA asks a single plain question: is the worker engaged as a person in business on their own account, or as an employee?
To answer it, the CRA examines six factors together. No single factor decides on its own.
The six factors the CRA checks
- Control. Who decides what work is done, how it is done, and when? An employee follows the payer’s direction on methods and schedule. A contractor controls how they deliver the outcome; the client specifies the result.
- Tools and equipment. Who provides them? An employee typically works on the company’s laptop, in the company’s office, with the company’s software licences. A contractor brings their own.
- Ability to subcontract. Can the worker send someone else to do the job or hire their own helpers? A genuine contractor usually can. Someone who must do the work personally, every time, looks like an employee.
- Financial risk. Can the worker lose money on the deal? A contractor quoting a fixed fee can lose if the job runs long or the client does not pay. An employee gets paid regardless.
- Responsibility for investment and management. Does the worker invest in their own business assets, office space, or staff, and manage them? Employees do not carry that kind of capital responsibility.
- Opportunity for profit. Can the worker increase their earnings through efficiency, better management, or taking on more clients? An employee earns what the paycheque says, no more.
Put them together and the pattern is usually clear. A receptionist who works 9 to 5 at your front desk, on your computer, answering to you daily, is an employee, even if both of you signed a paper that says “independent contractor.” A bookkeeper who serves eight clients, sets her own hours, works from her own office, and bills per project is a contractor. The grey zone is everything in between.
Quebec plays by different rules
If the contract was formed in Quebec, the CRA does not use the common-law approach described above. It applies the Civil Code of Quebec, which uses a three-step test instead of two, and different legal definitions of a contract of employment versus a contract for services. The practical factors look similar, but the legal analysis is distinct. If you hire in Quebec, do not assume an Ontario or BC answer applies.
Not sure? Ask the CRA for a ruling
You do not have to guess. Either the payer or the worker can ask the CRA for a formal CPP/EI ruling on the employment status. You can request it through My Business Account (as a payer) or My Account, through an authorized representative, or by mailing Form CPT1, Request for a CPP/EI Ruling, to your tax services office.
Watch the deadline: the request has to be made by June 29 of the year following the year the work relates to. So if the question is about work done in 2026, you need to request the ruling by June 29, 2027. The CRA’s decision letter is binding unless appealed, and it applies to a specific period of employment. If the terms of the arrangement change afterwards, you can ask for a fresh ruling.
Three traps that catch small businesses
First, paper over reality. A contract that says “contractor” will not save you if the day-to-day relationship has every hallmark of employment. The CRA looks at what happens, not just what was written.
Second, assuming part-time or seasonal means contractor. A part-time employee is still an employee. Hours do not decide the question; the six factors do.
Third, the one-client contractor. Someone who works only for you, full time, year after year, with no other clients and no real business of their own, will attract the CRA’s attention fast. That is exactly the fact pattern that triggers reviews.
