General vs. Limited Partnerships in Ontario

When people in Ontario talk about “a partnership,” they usually mean a general partnership — the default structure that exists whenever two or more people carry on business together with a view to profit. But Ontario law also recognizes a second, distinct structure: the limited partnership, governed by the Limited Partnerships Act. The two share the word “partnership,” but the liability picture for the people involved can look very different depending on which one applies.

The core distinction comes down to two things: who’s exposed to unlimited personal liability, and who gets a say in running the business. In a general partnership, those two things travel together — every partner who can lose everything also generally gets a voice in management. In a limited partnership, they’re deliberately separated, which is exactly what makes the structure useful for certain kinds of businesses and investments.

Both structures are built on top of the same underlying idea of “carrying on business together with a view to profit,” and in both cases the partnership itself is not treated as a fully separate legal entity the way a corporation is. What changes between the two is how the law allocates risk among the people involved, and what formalities are needed before that allocation takes effect. Understanding those differences matters whenever more than one person is putting money, time, or reputation into a shared venture, since the wrong assumption about which structure applies can leave someone far more exposed than they realized.

A general partnership is the structure covered in our broader guide to partnership agreements in Ontario. Every partner has unlimited personal liability for the partnership’s debts and obligations, and — absent an agreement saying otherwise — every partner can generally bind the firm to contracts and obligations within the ordinary course of business, even without the other partners’ knowledge or consent.

This arrangement has real advantages: it’s simple, flexible, and doesn’t require any special registration to come into existence (a business name registration may still be needed, but that’s separate from the partnership itself). The tradeoff is that every partner is personally on the hook, with their own house, savings, and other assets exposed if the business can’t pay its debts. There’s no corporate veil standing between the business and the people who own it.

Because liability and management control are bundled together, a general partnership tends to work best when all the partners genuinely want to be involved in running the business, and are comfortable with that level of personal exposure in exchange for that level of control.

It’s also worth remembering that a general partnership doesn’t require every partner to contribute equally, or even similarly, to be bound equally by its risks. A partner who contributed a small amount of capital but takes an active operational role can still face the same unlimited personal liability as a partner who contributed most of the money. Agreeing, in writing, on how responsibilities and authority are actually divided — even though it won’t change what outside creditors can pursue — can at least clarify how partners expect to share that risk between themselves.

A limited partnership splits the partners into two categories. At least one general partner retains unlimited personal liability and runs the business, much like a partner in an ordinary general partnership. Alongside them sit one or more limited partners, whose liability is generally capped at the amount of their investment in the partnership — they can lose what they put in, but their personal assets beyond that are generally protected, provided they stay within the limited partner role.

This structure is common where some people want to invest capital without taking on unlimited exposure or day-to-day management responsibility, while others are prepared to run the business and accept the liability that comes with it. Real estate syndications and certain investment funds are frequent users of the limited partnership structure for exactly this reason — passive investors contribute capital as limited partners, while a general partner (often a corporation specifically formed for the purpose) manages the underlying business.

One of the sharpest practical differences between the two structures is how they come into existence. A general partnership can exist in substance the moment people start carrying on business together with a view to profit — no filing, registration, or written agreement is legally required for the Partnerships Act to apply.

A limited partnership works differently. To obtain limited partner status for anyone involved, the partnership generally needs to be properly registered under Ontario’s Limited Partnerships Act, with a declaration identifying the general partner(s) and other required information filed with the province. Without that registration, the liability protection that makes a limited partnership attractive in the first place generally won’t be available — the arrangement risks being treated as an ordinary general partnership instead, exposing everyone involved to unlimited liability.

Keeping that declaration current matters too. If the general partner changes, or other key details shift, the public record generally needs to be updated to reflect it, since the declaration is what the outside world — including creditors — relies on to know who actually carries unlimited liability for the business.

This registration step is also what gives a limited partnership its public identity as a distinct structure in the first place. Without it, there’s no reliable way for third parties — or the partners themselves — to confirm who is a general partner carrying unlimited exposure and who is a limited partner whose liability is meant to be capped. That distinction is exactly what the limited partnership structure exists to provide, so treating the registration step as a formality to get around to later, rather than a foundational part of the structure, tends to undermine the whole point of setting it up this way.

The liability protection a limited partner enjoys comes with a significant condition: staying out of management. Under the Limited Partnerships Act, a limited partner who takes part in controlling or managing the business can end up personally liable as though they were a general partner — at least for obligations connected to that involvement.

This creates real tension for investors who want some influence over a business they’ve put money into but also want to keep their liability capped. Certain protective rights — like voting on fundamental changes to the partnership, or reviewing its financial records — are generally permitted without crossing the line into “management.” But taking an active, operational role, directing day-to-day decisions, or holding yourself out to third parties as having management authority, is exactly the kind of conduct that risks losing the protection the structure was meant to provide.

Anyone considering a limited partner role should understand, going in, how much involvement they can have before that protection starts to erode — this is a technical area where the specific facts matter a great deal, and general information like this article can’t substitute for advice on your particular arrangement.

A general partnership tends to suit situations where the people involved want to be hands-on, the business is relatively low-risk, and simplicity matters more than a liability shield. Two tradespeople running a shared contracting business, for example, often default into this structure without much formality.

A limited partnership tends to suit situations with a clearer split between capital and control — passive investors who want exposure to a business’s returns without unlimited liability or management duties, paired with an operator or sponsor prepared to take on both. It’s also worth remembering that neither structure removes unlimited liability from everyone involved; a limited partnership just concentrates it in the general partner role, which is often filled by a corporation rather than an individual for that reason.
