Canada (Ontario) coverage, pricing, and sources

Canada (Ontario) is in beta. Check the live pricing page or contact support before relying on it in production.
CA-ON covers corporations incorporated in Ontario. In Canada a company is incorporated either federally or in one province or territory, and each keeps its own register. A federal corporation that registers in Ontario to do business there is a Canada (Federal) company: use countryCode: "CA-FED" and its corporation number. CA-ON search does not return it, and its Ontario record, when asked for by Ontario Corporation Number, is flagged as an extra-provincial registration. CA on its own is not a jurisdiction.

Data Sources

Search and company data are read live from the register’s public search. The public record carries no street address, no Business Number and no people. Directors and officers are not offered yet: the register lists them only on a report.

​
Company Identifiers

​
Query Identifiers

A 9-digit number is not an OCN. On the Ontario register it is the Business Identification Number (BIN) of a business name or partnership, which CA-ON does not cover; elsewhere it is usually a Canada Revenue Agency Business Number, which the Ontario register does not publish.

Search Capabilities

Search is free. Only company data retrieval is charged.
Search returns corporations formed in Ontario only. Extra-provincial corporations (formed federally, in another province or territory, or abroad, and registered in Ontario) are left out, and so are the register’s business names, sole proprietorships and partnerships. Results carry the city, province and country of the registered office.

​
Active companies only

Search returns inactive corporations too (dissolved, cancelled, amalgamated). With activeOnly=true they are removed from the answer, from the status the register prints for each result.

Supported Entity Types

​
Federal and other extra-provincial corporations

A corporation formed outside Ontario that does business there registers as an extra-provincial corporation and receives an Ontario Corporation Number from the same series. CA-ON never presents it as an Ontario incorporation:
  • search does not return it;
  • asked for by its OCN, legalForm.localName is the register’s type (for example Extra-Provincial Federal Corporation with Share), standardized by its own form (Corporation, or Nonprofit Organization without share capital);
  • status.localName is the register’s Refer to Home Jurisdiction, with the standardized status UNKNOWN: the Ontario register does not hold the corporation’s status;
  • status.statusDetails.additionalInfo names the governing jurisdiction. For a federal corporation it reads “Extra-provincial registration in Ontario of a corporation formed under federal law (governing jurisdiction: Canada - Federal). Its own record is Canada (Federal), CA-FED; the Ontario register does not publish its federal corporation number or Business Number.”
Search the corporation by name in Canada (Federal) for its own record, directors and beneficial owners.
