Sole proprietorship, partnership, or corporation — what each one is, and who each suits.
Business · Updated July 2026 · 7 min read
Every business in Canada takes one of a few basic legal forms. The choice affects who is liable for the business's debts, how it is taxed, how much paperwork it carries, and how easily it can raise money or bring in owners. This guide sets out the main options in plain terms.
A sole proprietorship is one person carrying on business in their own name. It is not a separate legal entity: the owner and the business are the same in law. That makes it the simplest and cheapest form to start, but the owner is personally liable for all of the business's debts and obligations, and the profits are taxed as the owner's personal income.
A partnership is two or more people carrying on business together. In a general partnership each partner is personally liable for the debts of the business — including those incurred by the other partners. A limited partnership allows some partners to limit their liability so long as they stay out of management, and a limited liability partnership, available to certain professionals, shields partners from liability for each other's negligence. A written partnership agreement is strongly advisable, though the relationship exists in law even without one.
A corporation is a separate legal person, distinct from the people who own and run it. Its owners — the shareholders — are generally not personally liable for its debts beyond what they paid for their shares. A corporation can own property, sue and be sued, and continue to exist regardless of changes in ownership. In exchange it carries more formality and cost: it must be incorporated, keep corporate records, file annual returns, and file its own tax return.
A freelancer or low-risk one-person venture often starts as a sole proprietorship for simplicity. Two or more founders testing an idea may begin as a partnership, ideally with a clear agreement. A business that wants to limit the owners' personal risk, bring in investors, or plan for growth and succession usually incorporates. The right answer depends on liability exposure, tax position and plans for the business — matters worth confirming with a lawyer or accountant.
