Can a sole proprietor hire employees in Canada?

Setting up a payroll account as a sole proprietor

A sole proprietor who wants to hire an employee registers a payroll program account, generally called an RP account, under their existing business number, or gets a business number first if they do not already have one for GST/HST or other purposes. This is the same type of account an incorporated employer uses, and it needs to be set up before the first pay run so remittances and reporting start correctly from day one.

Our answer on setting up payroll for a first employee in Ontario covers the practical steps in more depth, and those steps do not differ based on whether the employer is a sole proprietorship or a corporation.

Many sole proprietors already have a business number for GST/HST purposes by the time they hire their first employee, in which case adding the payroll account is a matter of registering an additional program account rather than starting from scratch. A sole proprietor who has never registered for anything with the CRA before will need to get a business number first, then add the payroll account to it.

The payroll and ESA obligations are the same either way

Once a sole proprietor has an employee, the obligations that follow are identical to those of an incorporated business. CPP and EI have to be withheld and remitted on schedule, income tax has to be deducted from each pay, and Employment Standards Act rules on minimum wage, hours of work, vacation pay, and public holiday pay all apply in full. Our answers on vacation pay and statutory holiday pay apply the same way to a sole proprietor’s employee as to anyone else’s.

Where the employer’s industry requires it, WSIB coverage is also mandatory regardless of business structure; our answer on WSIB coverage requirements covers which industries are captured. Incorporating does not add or remove any of these obligations; they attach to the fact of being an employer, not to a particular legal structure.

Where the real difference is: personal liability

The meaningful difference is what happens if the business cannot meet its obligations. A sole proprietorship has no separate legal existence from its owner, so unpaid wages, unremitted source deductions, and other business debts are the owner’s personal debts as well, with no corporate structure standing between the business and personal assets.

An incorporated business does create that separation for most debts, but it is worth being precise here: source deductions withheld from an employee’s pay are treated as trust funds, and a director of a corporation can still be personally assessed for unremitted amounts even with incorporation in place. Incorporating broadens the protection around most business debts; it does not eliminate personal exposure to unremitted payroll deductions specifically, in either structure.

Paying yourself vs. hiring your spouse

Paying yourself as a sole proprietor is not payroll in any sense; it is a draw against the profits of the business, with no T4, no CPP or EI withholding, and no separate reporting beyond what shows up on your own personal tax return. This is a common point of confusion for new business owners who assume any money leaving the business to them personally has to go through a payroll process.

Hiring an actual spouse or family member as an employee is different, since that is genuine payroll subject to the same rules as any other hire, provided the work is real and the wage is reasonable for the role. Our answer on paying children or a spouse a salary covers what the CRA expects to see for that arrangement to hold up.

The line between an owner draw and a family member’s wages matters most when the CRA reviews a sole proprietorship’s expenses, since a wage paid to a spouse for work that never actually happened is treated very differently than a genuine, documented employment relationship. Keeping a real job description, actual hours, and a market-reasonable wage on file protects the deduction if it is ever questioned.

What a first hire actually requires

Before the first pay run, a sole proprietor needs a registered RP payroll account, WSIB coverage if the industry requires it, a clear written employment offer covering wage, hours, and vacation entitlement, and payroll software or a provider set up to calculate and remit CPP, EI, and income tax correctly. None of this requires incorporating first, and many sole proprietors run payroll for one or more employees for years without ever changing their business structure, though growing headcount or liability exposure is often part of what eventually prompts that conversation.

It is easy for a first-time employer to underestimate how much of this is genuinely required rather than optional, since running a sole proprietorship up to that point has often meant relatively few formal obligations. Basic employment standards documentation, correctly calculated vacation and public holiday pay from the very first pay period, and a payroll account that is actually registered before wages are paid are not optional extras layered on top of hiring; they are the baseline that applies from the first employee onward, in a sole proprietorship exactly as much as in a corporation.

We set up payroll accounts and first-hire checklists for sole proprietors the same way we do for incorporated clients, since the mechanics are identical even though the liability picture differs. Our payroll services cover this setup, and our answer on comparing sole proprietorship and corporation taxes is a useful next read once payroll is running and the broader structure question comes up.
