Web Callsign Lookup
Look up an assigned Canadian amateur radio callsign using the public ISED amateur callsign list. The result shows the operator or club name, QTH and amateur qualifications.
Canadian callsigns only. Portable suffixes such as /P are ignored for the database search.
Data source: Innovation, Science and Economic Development Canada (ISED). The page uses a validated local copy so lookups continue to work even if the ISED download service is temporarily unavailable.
