The previous website for Canadian Amateur Callsigns has been discontinued. The database is now hosted directly by Industry Canada. The format of the database has changed. I have re-coded the callsign database scripts on this site. Our database will update automatically at 1:15 AM each weekday. Therefore, data returned in response to a query on our homepage will always be among the freshest and most up-to-date on the web.
