Does a professional corporation need to renew its certificate of authorization every year?

Most governing bodies require a professional corporation's certificate of authorization to be renewed on a regular basis, commonly annually, often alongside the licensed professional's own annual licence renewal — but the exact cycle and process is set by each regulator individually, not by a single province-wide rule. Missing a renewal can mean the corporation is technically practising without valid authorization, which is a real problem even if the underlying professional's individual licence is in good standing.

Because the requirement sits with the governing body rather than the corporate registry, renewing your professional corporation's certificate is a separate task from any corporate filings you make under the Business Corporations Act, such as annual returns. It's easy for the certificate renewal to get overlooked precisely because it isn't tied to the same calendar or the same government office as your corporate filings. Build a reminder into your practice's compliance calendar, confirm the current renewal cycle and any fee with your specific governing body, and don't assume that keeping the corporation in good standing at the corporate registry is the same as keeping the certificate current.
