the CRTC disregarded the non-consensus report from the DNCL Operations Working Group, which had strongly recommended against allowing telemarketers to download unmarked, untraceable copies of the do-not-call list. With the aim of protecting the confidentiality of cell and unlisted numbers, the non-consensus report had instead advocated a Query/Response methodology, wherein telemarketers would be able to query only the do-not-call status of numbers they already had in their possession. Although the CRTC had rejected the Query/Response methodology, citing grounds of operational cost and complexity, a one-number-at-a-time Query/Response turned out to be so operationally simple and inexpensive that it is provided by the CRTC, free of charge, without restriction, to anyone who cares to use it. Other jurisdictions such as the USA provide similar Query/Response functions to checklists of small sets of numbers simultaneously, also free of charge. Jurisdictions such as Australia protect subscriber privacy, precisely as envisioned by the minority report, by keeping the list in the form of a secure database, and providing only a "List Washing Service".
