Converting a Partnership into a Corporation in Ontario: What Changes

When a general partnership starts to outgrow its structure — more revenue, more risk, or partners who want a cleaner ownership and exit mechanism — converting a partnership to a corporation is a common next step. But like converting a sole proprietorship, this isn't a paperwork relabelling. A general partnership isn't even a separate legal entity to begin with; it's a factual relationship between the partners. Incorporating means creating something new and moving the business into it.

Here's what that process typically involves, step by step.

Step 1: Understand What You're Actually Leaving Behind

A general partnership under Ontario's Partnerships Act has no separate legal existence — there was never a "partnership entity" to convert, only partners who agreed to carry on business together and share liability jointly and severally for the partnership's debts and each other's acts done in the ordinary course of business. That joint-and-several exposure is usually the main reason partners look at incorporating: a corporation is a distinct legal person, which changes who is generally on the hook for the business's ongoing obligations going forward.

Step 2: Incorporate the New Corporation

The partners decide whether to incorporate provincially under the OBCA or federally under the CBCA, choose a named or numbered corporation, and file the articles. This is also the point to think about share structure. Will the partners hold shares in the same proportions as their old partnership interests, or does the ownership split change as part of the move?

Step 3: Move the Business Assets and Contracts Across

As with any conversion into a new legal entity, nothing transfers automatically:

• Contracts and leases signed by the partnership generally need to be assigned or re-signed in the corporation's name, with the other party's consent.
• The partnership's business name, if registered, needs a fresh registration under the corporation if you'll keep using it.
• Bank accounts and CRA program accounts, including GST/HST and payroll, need to be set up fresh under the corporation's own Business Number.
• Employees technically move to a new employer. Their existing terms and entitlements should be carried over carefully — changing the fundamentals of someone's employment without care can raise employment-law issues even in a well-intentioned restructuring.

Step 4: Put a Shareholders' Agreement in Place

Partners moving into a corporation together should not assume their old partnership arrangement, however informal, automatically governs their new relationship as shareholders. A shareholders' agreement — often a unanimous shareholder agreement (USA) — is the standard tool for setting out how the corporation will actually be run, how decisions get made, and what happens if one owner wants to leave, dies, or stops contributing. This is worth doing at the same time as incorporating, not as an afterthought.

Step 5: Wind Down the Partnership Itself

Once the business has moved to the corporation, the partnership as a factual relationship needs to be formally wound up between the partners: settling accounts, addressing any remaining partnership assets or liabilities, and confirming in writing that the partnership has ended. Because a partnership isn't registered the way a corporation is, there's no single government filing that "closes" it the way Articles of Dissolution close a corporation — but a business name registration tied to the old partnership should be updated or allowed to lapse once it's no longer accurate.

Tax and Employee Considerations to Flag Early

Moving partnership assets into a corporation can have tax consequences, and accountants and tax lawyers use specific mechanisms to manage that transition efficiently — this is not something to work out after the fact. On the employee side, keep in mind that Ontario's Employment Standards Act, 2000 minimum notice and termination obligations apply to the corporation as the new employer going forward; get advice before making any representations to employees about how the switch affects them.

Note that converting your own partnership into a corporation is a different transaction from selling a business to an outside buyer. If a sale to a third party is what you're actually contemplating, that involves its own set of considerations covered under Buying & Selling a Business.
