It's about time? We don't need it until 2013.
It would be convenient for the out-of-provincers who are used to 10-digit dialing, I suppose, but I don't think it was a big issue.
Incidentally other carriers in Saskatchewan (e.g. Access cable) have had 10-digit dialing for years. This is SaskTel POTS. SaskTel Mobility has had it for a long time too.
