Ontario partnerships run on the Partnerships Act, R.S.O. 1990, c. P.5, whose section 24 default rules impose equal profit sharing and equal management rights unless the agreement says otherwise. The province also enforces the Business Names Act, and a general partnership using a business name must register it; an unregistered firm can be blocked from maintaining a court proceeding on its business until it registers. Treat name registration as a precondition to enforcing contracts, not an afterthought.
British Columbia applies the Partnership Act, R.S.B.C. 1996, c. 348, which mirrors Ontario's default scheme of equal sharing and joint liability. Registration of the partnership and its business name runs through BC Registries, and the framework for limited partnerships and limited liability partnerships sits in the same statute, so a BC agreement should state plainly which form the partners intend.
Alberta governs partnerships under the Partnership Act, R.S.A. 2000, c. P-3, following the common pattern of presumed equality and unlimited liability for general partners. Alberta requires registration of trade names and partnership declarations with the Corporate Registry, and partners carrying on business there should confirm the filing is current before relying on the firm name in contracts.
Quebec is the outlier. Partnerships are governed by the Civil Code of Québec rather than a partnership act, and the province recognizes general, limited and undeclared partnerships with their own registration rules through the enterprise register. An agreement drafted for a common-law province will not map cleanly onto Quebec law, so a Quebec venture needs terms and citations built for the Civil Code. Partners operating across provincial lines should also watch for extra-provincial registration, since carrying on business in a second province usually requires a separate filing there.
