About this API
Corporations Canada maintains the register of businesses and not-for-profits incorporated federally — under the Canada Business Corporations Act, the Canada Not-for-profit Corporations Act and related statutes. For a given identifier the endpoint returns the corporate name and its history, status, governing act, registered office address, director limits, business number, annual meeting dates and the history of registry activities. No key is required, but the server sends no CORS header, so requests must be made server-side. The underlying dataset is published on open.canada.ca under the Open Government Licence – Canada.
Frequently asked questions
Do I need an API key?
No. The JSON endpoint is public and needs no key or registration — just a corporation number or a 9-digit business number.
What data does this API return?
For a given corporation: its name (with name history), status, governing act, registered office address, director limits, business number, annual meeting dates and the history of registry activities (e.g. incorporation, by-law filings).
Can this API be called directly from a browser?
No. The server sends no CORS header (Access-Control-Allow-Origin), so requests must be made server-side (a backend, serverless function or script) rather than from browser front-end code. That is why there is no live 'Try it' button here.
Who runs this API?
Corporations Canada, the Canadian federal corporate regulator, which is part of Innovation, Science and Economic Development Canada (ISED).
