The Fastest Way to Sort It Out
| Situation | Likely Filing | Legal Owner |
| One individual operating under a business name | Declaration of Trade Name | The individual |
| An existing corporation using another operating name | Declaration of Trade Name | The corporation |
| Two or more people carrying on business together | Declaration of Partnership | The partners, subject to partnership law |
| A separate legal entity is needed for ownership, liability, investment, or succession | Incorporation | The corporation |
The Central Difference: Liability
This is where the structures diverge most significantly.
Sole Proprietor with a Trade Name
The individual owns and operates the business. The individual is personally liable for the business’s obligations, debts, contracts, and any wrongdoing. A trade name registration doesn’t change that. The person is liable.
Partnership
In a general partnership, each partner is personally liable for the partnership's debts and obligations, and partners can be held jointly and severally liable for wrongful acts committed in the course of the business. Each partner can also bind the partnership when acting in the usual course of its business. A partnership doesn't shield personal assets. If the partnership defaults on a loan and can't repay it, a creditor can pursue the partners' personal assets. Please note that general partnerships are not the same as limited partnerships. Limited partnerships put liability on the general partner.
Another option is a limited partnership that has partners with limited liability (limited partners) and at least one partner with personal liability (general partner). Alberta recognizes limited partnerships under the Partnership Act.
Corporation
A corporation is a separate legal entity. The shareholders (owners) have limited liability; they’re liable only to the extent of their investment. Generally, shareholders are not personally liable for the corporation’s debts or obligations. Directors have specific statutory liabilities in certain contexts (payroll, environmental, health and safety), while shareholders are generally protected.
When Each Structure Fits
Use a trade name when:
- You're a sole proprietor and want to operate under a name other than your personal name.
- An existing corporation needs an operating name different from its legal corporate name.
- You understand that the filing doesn't create liability protection or exclusive rights.
- You're prepared to handle licensing, tax accounts, and brand protection as separate matters.
Consider incorporation when:
- You want a separate legal entity rather than a name tied to your personal assets and liabilities.
- Liability protection matters (you're providing services where risk is real, or you're seeking investors).
- Ownership structure, succession planning, investment, or exit strategy are important.
- You want to enable future sales or investments easily.
- Tax planning or deferral is relevant.
Consider a partnership when:
- Two or more people are sharing ownership and control of the business.
- You're comfortable with personal liability for the partnership's debt (or willing to use a limited partnership to limit it).
- You want to formalize ownership and operational terms.
Do not use a partnership for filing for an unregistered operating name.
If you're a sole proprietor with a business partner, do not necessarily file a partnership declaration just to add their name to the operating name, there might be more consideration to it. If you're unsure it can be worth consulting a lawyer. If the two of you are in actual business together as partners, you need a partnership agreement and a partnership declaration. If only one person owns the business but a partner is involved in operations, that's an employment or subcontracting relationship, not a partnership. Make sure you correctly identify the relationship to ensure you file the correct type.
Do Not Let the Name Drive the Structure
This is the central mistake. A polished brand can work as a sole proprietorship (trade name), partnership, or corporation. The legal structure should support the business's needs (liability, ownership, investment, taxes, succession). The operating name comes second.
