Converting a Partnership to a Corporation in Ontario

Many businesses start out as a partnership simply because it is the easiest structure to fall into — two or more people begin carrying on business together, and a partnership exists in law without anyone having to file anything. As the business grows, though, the features that make a general partnership simple to start can start to look like liabilities, quite literally.

The most common driver of conversion is limited liability. In a general partnership, each partner is generally personally liable, jointly with the others, for the partnership’s debts, which becomes a more serious exposure as the business takes on larger contracts, more employees, and greater financial risk. A corporation generally shields its shareholders from personal liability for the company’s own debts, which is often the single biggest reason a growing business considers converting. Our comparison of partnerships and corporations in Ontario covers this difference in more detail.

Beyond liability, a corporation also tends to make it easier to raise capital, since investors and lenders are generally more comfortable dealing with defined share classes and a structure built for outside investment than with a partnership interest. A corporation also has a continuous existence of its own, separate from its owners, so it does not automatically face dissolution issues the way a partnership can when a partner leaves or dies.

A corporate structure can also make it considerably easier to bring in new owners or gradually transfer ownership over time — selling or issuing shares is generally more straightforward, and better understood by outside investors, than negotiating a new partner’s entry into a partnership from scratch each time. For a growing business planning to bring in investors or expand its ownership base, this flexibility is often a significant factor in the decision to convert.

The first concrete step in converting is generally incorporating a new corporation, either federally or provincially in Ontario, with its own articles of incorporation, share structure, and corporate records. The former partners typically decide at this stage how share classes will be structured, what each partner’s proportional ownership will look like, and whether any partners will hold different classes of shares reflecting different rights or priorities.

It is generally worth treating this step with the same care as drafting an original partnership agreement — a shareholder agreement for the new corporation can address many of the same issues a good partnership agreement would have covered, such as decision-making authority, what happens if a shareholder wants to leave, and how a deadlock between shareholders gets resolved.

Partners also need to decide, at this stage, whether to incorporate federally or under Ontario’s own corporate statute, which can affect where the business is permitted to operate under that name and what ongoing filing obligations apply. This is generally a practical, business-specific decision rather than one with a single right answer for every converting partnership.

Because the new corporation is a separate legal entity from the old partnership, the partnership’s assets generally need to be formally transferred into it — equipment, inventory, intellectual property, real property, and any other property the business relies on. This transfer typically needs to be documented and valued properly, both for the corporate records and because of the tax consequences a transfer of this kind can trigger.

Existing contracts with suppliers, landlords, and clients generally need to be assigned or novated to the new corporation as well, which often requires the other party’s consent, depending on what the underlying contract says about assignment. Simply continuing to operate under the old partnership’s contracts without addressing this can leave it unclear which entity is actually bound going forward.

Employees are typically transferred to the new corporation as their employer going forward. This generally needs to be handled carefully to preserve each employee’s accrued entitlements — such as length of service for notice and severance purposes — rather than treating the transition as a termination followed by a fresh hire, which can create unintended employment law exposure.

Licences, permits, and insurance policies held by the partnership often need similar attention, since many of these are issued to a specific legal entity and do not automatically carry over to a newly incorporated company. Reviewing what the business currently holds, and confirming with each issuer what is required to transfer or reissue it, is generally a worthwhile step to work through alongside the asset and contract transfers.

As part of the conversion, partners typically become shareholders of the new corporation, usually in proportion to the value of the capital or assets they contributed from the partnership. This exchange is generally documented through share subscription agreements, and the relative share allocation often mirrors — though it does not have to exactly mirror — each partner’s prior ownership interest in the partnership.

This is also a natural point to revisit governance questions that the partnership agreement may have addressed informally, or not addressed at all — voting rights, what happens if a shareholder wants to sell their shares, and how disputes between shareholders will be resolved going forward. A new shareholder agreement is generally the vehicle for setting these terms, serving a similar function to a partnership agreement but adapted to the corporate structure.

Incorporating a new company does not, by itself, end the old partnership — the partnership generally still needs to be formally wound up, including settling any outstanding debts and obligations, once its assets and operations have been transferred into the corporation. Our guide to ending a business partnership in Ontario covers the general wind-up process in more detail.

It is particularly important not to overlook this step, since partnership debts generally remain the partnership’s and the partners’ personal responsibility unless creditors specifically agree to release them in favour of the new corporation. Our guide to who pays partnership debts after dissolution covers how that liability generally works.

Partners sometimes assume the old partnership can simply be left dormant rather than formally wound up, since the business is now operating through the corporation in practice. This is generally worth avoiding — an inactive partnership can still carry obligations, such as filing or registration requirements, and leaving it in limbo rather than closing it out properly can create loose ends that surface unexpectedly later.

Converting a partnership into a corporation generally raises real tax questions — including how the transfer of partnership assets into the corporation is characterized, and whether any available tax provisions can be used to defer tax that might otherwise arise on that transfer. These rules are detailed and depend heavily on the specific facts of the business, so this is an area to discuss directly with an accountant or tax professional rather than relying on general information.

On the liability side, it is worth being clear that limited liability generally applies going forward, to obligations the new corporation itself incurs — it generally does not retroactively protect partners from debts or liabilities the partnership already had before the conversion. Partners considering conversion specifically for liability protection should keep this distinction in mind, and may want legal advice about how to handle outstanding obligations as part of the transition.
