Limited partnership (LP)

A limited partnership is a partnership with at least one general partner and at least one limited partner. Under Alberta’s Partnership Act and Ontario’s Limited Partnerships Act, a limited partner is not liable for the partnership’s obligations beyond what it contributes or agrees to contribute, subject to each Act, including its rule on taking part in control of the business.

A buyer or seller may meet a limited partnership when a business is held in a partnership rather than a corporation. Under both Acts, a general partner carries the liabilities of a partner in an ordinary partnership, and a limited partner who takes part in the control of the business can be liable as a general partner. This entry covers Alberta and Ontario only; check the Act where the partnership was formed. See whether buying into a partnership is the same as buying shares.

How it works

Alberta’s Act, subject to section 52(2), forms a limited partnership when a certificate is filed with and recorded by the Registrar. Ontario’s forms one when a declaration is accepted for filing. In both, a general partner has no authority, without the written consent or ratification of all the limited partners, to admit a person as a general partner, or as a limited partner unless the partnership agreement gives that right. Both Acts also say a limited partner whose surname appears in the firm name, contrary to the Act, can be liable as a general partner to a creditor who lacked actual knowledge. Ontario’s Act requires the general partners of a limited partnership, other than an extra-provincial one, to keep a current record of limited partners.

What to ask

  • Who the general partners and limited partners are, and under which province’s Act the partnership was formed
  • What the partnership agreement says about admitting or replacing partners
  • Whether the limited partners’ consents are in writing
