After many years, the "defacto" reference for Canadian callsigns has closed down.

While RAC does have a Canadian callsign lookup page, they were often about a month or more behind with updates.  Work is progressing to fix that.

The most up to date one was considered to be on callsign.ca.

That webmaster has decided to merge that domain with Radio Amateur du Quebec's main domain.  You'll notice that visiting callsign.ca brings up the Radio Amateur du Quebec page with this notice:

Please note that callsign.ca functions are now hosted on Industry Canada.

So the database is returning to Industry Canada once again.  Hopefully, it will be kept up to date as well as callsign.ca was.

New links are as follows:

Main search page, allowing search by callsign, name, Province or Postal Code

Special Event Callsign Search, indexed by date of event

Available Callsign Search (for soon-to-be new hams, or hams moving to another Province)
