Eighty per cent of Canadians receive fewer telemarketing calls as a result of the CRTC's national do-not-call list (DNCL), the commission said Wednesday. The commission said a survey conducted from March to April 2011 by the Marketing Research and Intelligence Association (MRIA) found that a significant amount of Canadians reported receiving fewer telemarketing calls since adding themselves to the do-not-call list. The commission said it received 115,113 complaints for the period of March to April of this year, totalling 398,809 complaints since the launch of the list in September 2008. There are total of nearly 9.5 million numbers registered with the list, which have accumulated since the launch of the service three years ago, the CRTC said. The commission said the telemarketer registrations have increased by 930 for a total of 8,478. “Telemarketers also purchased 2,350 subscriptions which allow them to update their calling lists by 'scrubbing,' or removing, registered phone numbers,” the commission said. In a release, the CRTC said that it concluded 129 investigations from March to April 2011. “To date, over 90 per cent of investigations have been concluded,” it said. In terms of penalties for violations of the unsolicited calling rules, the commission said it imposed administrative monetary penalties totalling $1,922,000. During the survey period, the CRTC said that total penalties and other payments were $2,663,000. The commission said its expenses for activities related to the do-not-call list were approximately $3.1 million. Bell Canada Enterprises Inc.’s costs for operating on the list were nearly $3 million. The commission said operating costs are recovered through subscription fees that are charged to telemarketers who purchase the list.
