The CRTC has decided to extend the length of time a telephone number stays on the National Do-Not-Call registry from three years to five. The new provision will automatically apply to all numbers registered, about 6.7 million, according to the commission. This is one among a few changes, the commission made today to the unsolicited telemarketing rules. As well, the CRTC is allowing electoral candidates not affiliated with a registered party to be exempt from the National DNCL rules. In addition, the use of automatic dialing and announcing devices (ADADs) for non-telemarketing purposes such as debt collection must following the commission’s rules for calling-hour restrictions if they aren’t specifically set out in provincial legislation.
