Independent Contractor Agreements in Ontario: What to Include and Why It Matters

Whether someone is an employee or an independent contractor affects far more than what the contract calls them. Employees are generally entitled to protections under employment standards legislation, potential entitlements on termination, and various statutory benefits, while genuine independent contractors operate their own business and generally fall outside many of those protections, in exchange for greater independence and, often, higher pay for the work itself.

Because of this difference, simply labelling someone a “contractor” in a written agreement doesn’t settle the question. Ontario courts and tribunals look past the label to the actual substance of the working relationship, and if that relationship functions more like employment, it can be treated as employment regardless of what the contract says on paper.

This matters for both sides of the relationship. A worker who believes they’ve been misclassified may be entitled to pursue statutory entitlements they were denied, while a business that misclassifies workers can face significant retroactive liability. Getting the classification right from the outset protects both parties from an unpleasant and costly surprise later.

Courts generally look at a range of factors to assess the true nature of a working relationship, including the degree of control the hiring party exercises over how, when, and where the work is done; whether the worker can profit from good management of their own work or bears the risk of loss; whether the worker owns their own tools and equipment; and whether the worker can genuinely work for multiple clients rather than being economically dependent on a single hiring party.

No single factor is decisive on its own — courts weigh the overall picture the relationship presents. A worker who sets their own hours, uses their own equipment, bills multiple clients, and has real discretion over how the work gets done looks much more like a genuine contractor than one who works fixed hours at the hiring party’s premises, using the hiring party’s equipment, exclusively for that one client.

In addition to these traditional factors, some tribunals also consider whether the worker is genuinely operating a business with its own risk of profit and loss — for example, quoting fixed prices, incurring its own overhead, and having the ability to hire subcontractors or assistants to complete the work, rather than being personally required to perform every task themselves.

A well-drafted independent contractor agreement should clearly describe the scope of services, the fee structure, and the term of the engagement, along with language confirming the contractor operates as an independent business responsible for their own taxes, insurance, and business expenses. It should also avoid language that mirrors typical employment terms, such as describing paid vacation, sick days, or a fixed probationary period.

It’s also worth specifying that the contractor is free to provide services to other clients, and that the hiring party isn’t dictating specific working hours or requiring exclusive availability, where that reflects the reality of the arrangement. The more the written agreement matches how the relationship will actually operate day to day, the more protection it offers if the classification is ever questioned.

Beyond the written agreement, how the relationship is actually managed matters enormously. A hiring party that closely supervises a contractor’s daily schedule, requires attendance at internal meetings unrelated to deliverables, requires the contractor to use company email and equipment, and controls the specific methods used to complete the work is behaving more like an employer, regardless of what any written agreement says.

Genuine contractor relationships tend to focus on outcomes and deliverables rather than process — specifying what needs to be achieved and by when, while leaving the contractor meaningful discretion over how to get there. Maintaining this distinction in practice, not just on paper, is often the most important factor in preserving a genuine contractor classification over time.

It’s also worth periodically checking whether a long-running contractor relationship has drifted toward something closer to employment without anyone intending it — more fixed hours, deeper integration into internal processes, or a growing reliance on that single hiring party for most of the contractor’s income. These gradual shifts are common, and revisiting the arrangement periodically helps catch drift before it becomes a real problem.

Independent contractors are generally responsible for their own income tax remittances, and for registering for and collecting HST if their revenue exceeds the applicable threshold, unlike employees, whose employers withhold and remit taxes on their behalf. A contractor agreement should make clear that the contractor bears this responsibility directly.

Hiring parties should be cautious about treating a worker as a contractor for tax purposes while otherwise managing the relationship like employment, since a misclassification can expose the hiring party to liability for unremitted source deductions, penalties, and interest if the relationship is later reclassified as employment by a tax authority or a court.

It’s generally a good practice for contractors to invoice through a registered business name, maintain separate business banking, and handle their own bookkeeping, since these practical habits reinforce the independent, business-like nature of the relationship in ways that go beyond the wording of the contract itself.

Unlike some employment relationships where work product ownership may be addressed by default legal principles, a contractor agreement should explicitly state that intellectual property created for the hiring party is assigned or licensed to them, since the default rules around contractor-created work can be less favourable to the hiring party than many assume.

Confidentiality obligations are also worth addressing explicitly, particularly where the contractor will have access to sensitive business information. Our guide to non-disclosure agreements in Ontario covers what these provisions typically include and where their limits tend to lie.

Non-compete and non-solicitation provisions can also appear in contractor agreements, though they’re generally scrutinized closely and need to be reasonable in scope, duration, and geographic reach to be enforceable. An overly broad restriction risks being struck down entirely if challenged, rather than simply narrowed to a more reasonable version.

If a contractor relationship is successfully challenged and reclassified as employment, consequences can include liability for unpaid statutory entitlements, potential notice or severance obligations, and liability for unremitted taxes and source deductions — sometimes going back years, with penalties and interest layered on top of the original amounts owed.

These claims can also arise unexpectedly, such as when a single contractor relationship ends and the former contractor pursues a claim, or when a broader review is triggered by an unrelated regulatory audit. Because the exposure can affect not just one relationship but every similarly structured contractor arrangement a business relies on, the risk is often larger in aggregate than it first appears when looking at a single contract.

Given these risks, businesses that rely heavily on contractor relationships benefit from periodically reviewing how those relationships actually function in practice, not just how they were originally documented, since a relationship that started as genuine independent contracting can gradually shift toward something that looks more like employment as it continues over time.

The clearest way to avoid a misclassification dispute is to align the written agreement, the day-to-day management of the relationship, and the tax treatment from the very beginning, rather than trying to correct a mismatch after the relationship has been running for some time.

Where a business genuinely needs the kind of oversight and integration that comes with an employment relationship, it’s often more sustainable — and less legally risky — to structure the role as employment from the outset, rather than trying to fit a role that doesn’t function independently into a contractor label.

For businesses working with multiple contractors, it can also be worth having a standardized agreement template reviewed periodically to reflect current best practices, rather than relying on a version drafted years ago that may no longer reflect how courts and tribunals currently assess these relationships. A small upfront investment in getting the template right pays off across every contractor relationship that uses it.
