In Canada, an Amateur Radio Operator Certificate is valid for life. Once you have passed the examination and received your certificate, you never have to pay a renewal fee or retake the test to keep your current privileges. This is a unique benefit of the Canadian system. Amateurs in many other countries, such as the United States, must renew their licenses periodically (e.g., every 10 years). However, keep in mind that ISED can suspend or revoke your certificate if you violate regulations or fail to maintain a valid mailing address.
