Sole Proprietorship vs Partnership in Canada
Sole proprietorship vs partnership in Canada: compare liability, taxes, control, and registration to see which structure fits your small business today.
The difference in a sole proprietorship vs partnership in Canada comes down to ownership: a sole proprietorship has one owner, while a partnership has two or more. When you compare partnership vs sole proprietorship, the decision usually turns on personal liability, how income is taxed, who controls the business, and what must be registered.
What a sole proprietorship is
A sole proprietorship is an unincorporated business owned by one person. There is no legal separation between you and the business, so contracts, debts and lawsuits are yours personally. You report business income on Form T2125, Statement of Business or Professional Activities, filed with your personal T1 return, and profit is taxed at your personal marginal rate. A sole proprietorship can operate under your own legal name or a registered business name, and registration requirements depend on your province or territory and how you name the business.

What a general partnership is in Canada
A general partnership exists when two or more people carry on business together with a view to profit. In most Canadian provinces and territories, a general partnership can arise from conduct alone, even without a written agreement, which is exactly why a written partnership agreement is strongly recommended. Each general partner is typically personally liable for the partnership's obligations, and a creditor may be able to pursue any one partner for the full amount before that partner seeks contribution from the others. A limited partnership is different: it has at least one general partner with unlimited liability and limited partners whose exposure is generally capped at their investment. For broader context on how this fits with other structures, see types of business structures in Canada.
Sole proprietorship vs partnership at a glance
| Factor | Sole proprietorship | General partnership |
|---|---|---|
| Number of owners | One | Two or more |
| Legal status | No separation from the owner | Generally not a separate legal person, but treated as a partnership for filing purposes |
| Personal liability | Unlimited for the owner | Unlimited for each general partner |
| How income is taxed | Owner reports on T1 using Form T2125 | Partnership files an information return; each partner reports their share on their own T1 |
| Control | Owner decides alone | Shared, unless the agreement says otherwise |
| Registration | Business name registration where required | Registration plus a recommended written agreement |
Liability is the point people underestimate most. In both structures, your personal assets are generally exposed to business debts and claims, which is why sole proprietorship liability and partner exposure deserve a careful look before you start.
Tax treatment: T1, T2125 and partnership returns
A sole proprietor reports all business income and expenses on Form T2125 with the personal T1 return. A partnership is generally not a taxpayer itself; instead, it files a partnership information return, and each partner includes their share of income or loss on their own T1 return, taxed at their personal marginal rate. Partners are not employees of the partnership, so payments to partners are typically not run through a payroll account as salary, and partners cannot deduct a draw as a business expense. Where a partner is paid for services outside the partnership role, a T4A may apply. As of the current tax year, confirm current filing rules on the CRA website. For rates and brackets, see sole proprietorship tax rate in Canada.
Control, profits and decision-making
A sole proprietor decides alone: pricing, hiring, borrowing and expansion are single-owner calls. A partnership spreads that control, which can add capital and skills but also friction. Key items to settle in writing include:
- How profits and losses are split, and whether that differs from capital contributions
- Who can bind the partnership to contracts or borrow money
- How disputes are resolved and how a partner exits, retires or sells a share
- What happens on death or incapacity of a partner
- Whether new partners need unanimous consent
Registration, naming and CRA accounts
Both structures may require a federal or provincial business name registration, depending on the name used and where you operate. A partnership typically registers the partnership name and lists the partners, and may also need a Business Number (BN) with program accounts under the partnership itself. GST/HST registration applies to the business, not to each partner personally, and a separate payroll account is needed if the business hires employees. Useful next steps: whether you need to register and how to get a Business Number.
Which structure fits your situation?
A sole proprietorship usually suits one owner who wants simplicity, full control and minimal setup. A general partnership can make sense when two or more people bring complementary skills, capital or client bases, and are prepared to share both risk and reward. If liability or tax planning is a serious concern, incorporation is the alternative to weigh, since a corporation is a separate legal person. Compare all three in sole proprietorship vs corporation. Because partnership law is largely provincial and tax outcomes depend on your facts, confirm details with your provincial or territorial registry and the CRA, and get professional advice before signing anything.
Frequently asked questions
What is the main difference between a sole proprietorship and a partnership?
A sole proprietorship has one owner who is the business for legal and tax purposes, while a partnership has two or more owners sharing profits, losses and decisions. A sole proprietor reports business income on Form T2125 with a personal T1 return. In a partnership, the partnership files an information return and each partner reports their share on their own T1. Personal liability is generally unlimited in both.
Is a partnership taxed differently than a sole proprietorship in Canada?
A partnership generally does not pay income tax itself. It files a partnership information return, and each partner includes their share of income or loss on their personal T1 return, taxed at that partner's marginal rate. A sole proprietor reports all business income alone on Form T2125. As of 2026, confirm current filing requirements on the CRA website, since deadlines and forms can change.
Do I need a written partnership agreement in Canada?
In most provinces and territories a general partnership can exist without a written agreement, but relying on that is risky. A written partnership agreement sets out profit shares, capital contributions, decision-making, dispute resolution, and what happens if a partner leaves or dies. Without one, provincial partnership legislation and default rules apply, which may not reflect what the partners intended. Legal advice is worth getting.
Can I change a sole proprietorship into a partnership?
Often, yes. You would typically register or update the business name and add the new partner, update CRA accounts such as a GST/HST account so they reflect the partnership, and put a written partnership agreement in place. Because ownership changes, contracts, bank accounts and insurance may need updating. Confirm the exact steps with your provincial or territorial registry and the CRA.
