Sole Proprietor vs. Partnership vs. Corporation Choosing the Right Business Structure
The structure you choose on day one affects your taxes, your personal liability, and your ability to grow. Here is every option explained in plain language.
The Main Options
When starting a business in Canada, you have four structural choices: sole proprietorship, general partnership, limited partnership (LP), limited liability partnership (LLP), and corporation. Each comes with different legal, financial, and operational implications.
Sole Proprietorship
The simplest structure you and the business are the same legal entity. No registration beyond a business name is required if operating under your own name. All profits are taxed as personal income. The critical downside is unlimited personal liability: if the business is sued or owes money, your personal assets are fully exposed.
General Partnership
Two or more people carrying on business together for profit. No separate legal entity is created. Each partner is personally and jointly and severally liable for all debts and obligations of the partnership including the acts of other partners taken in the partnership's name, even without your knowledge.
Limited Partnership (LP)
An LP has at least one general partner (unlimited liability, full management control) and one or more limited partners (liability capped at their investment, no management role). The LP is commonly used in real estate investment, private equity, and fund structures. A limited partner who participates in management risks losing limited liability status.
Limited Liability Partnership (LLP)
An LLP protects each partner from personal liability for the negligence or misconduct of co-partners. Unlike an LP, all partners can participate in management. In Ontario, LLPs are available primarily to regulated professionals lawyers and accountants. An LLP does not protect a partner from liability for their own negligence.
Corporation
A corporation is a separate legal person it can own property, enter contracts, and sue or be sued in its own name. Shareholders enjoy limited liability: their personal exposure is generally capped at their investment. The corporation pays tax at the corporate rate, which is significantly lower than personal rates for most Canadian small businesses.
Key advantages of incorporating:
- Limited liability for shareholders
- Lower corporate tax rate and access to the Small Business Deduction
- Easier to bring on investors and raise capital
- Perpetual existence the business survives any individual owner
- Income splitting and tax planning opportunities
