For federally incorporated companies that operate in Ontario, the Government of Canada’s federal corporate regulator, Corporations Canada, provides a search engine in which the public can search for a company using its corporate name, corporation number, and/or business number. There are additional search options available, such as the province of the registered office, the corporation status (for example, whether it is active or inactive), and governing legislation. These options are particularly useful if the company name renders a large quantity of search results. The search is available at: https://ised-isde.canada.ca/site/corporations-canada/en and is free of charge.
For companies that are provincially incorporated under Ontario law, Service Ontario’s “Ontario Business Registry” allows for basic information to be obtained through a company search using a corporate name, corporate number, or incorporation date. The search is available at: https://www.ontario.ca/page/business-services. No account is needed to make this search.
