Innovation, Science and Economic Development Canada (ISED) requires that your Amateur Radio Operator Certificate be retained at your mailing address of record. This ensures that the primary station address matches the regulatory documentation and that the certificate is accessible if an inspector requests it.

Keeping it locked away in a safety deposit box is also incorrect, as it must be available at the primary operating address.
