National Do Not Call List

National Do Not Call List is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand National Do Not Call List rather than just read about it. In short: The National Do Not Call List (DNCL) (French: Liste nationale de numéros de télécommunication exclus) is a list administered by the Canadian Radio-television and Telecommunications Commission (CRTC) that enables residents of Canada to decide whether or not to receive telemarketing calls. It was first announced by the Government of Canada on 13 December 2004.

Key takeaways

  • National Do Not Call List belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect National Do Not Call List to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of National Do Not Call List from memory before moving on to harder problems.

Reference excerpt

The National Do Not Call List (DNCL) (French: Liste nationale de numéros de télécommunication exclus) is a list administered by the Canadian Radio-television and Telecommunications Commission (CRTC) that enables residents of Canada to decide whether or not to receive telemarketing calls. It was first announced by the Government of Canada on 13 December 2004. The DNCL has been labelled a "disaster" and over a decade after the law's creation, many telemarketers are either unaware or do not follow the rules imposed by the DNCL. The DNCL continues to receive heavy criticism, the latest being from Senator Percy Downe who referred to it as "totally useless", due to the costly but totally ineffective enforcement, the large number of exempt groups and the ability for anyone from anywhere in the world to purchase sets of phone numbers for relatively low fees, and then abuse the Do Not Call List as a calling list. Senator Downe cited multiple examples of constituents, whom he had personally added to the list, receiving a sudden increase in telemarketing calls three months later. On 20 April 2009, the CRTC announced that telephone and fax numbers on the list would be listed on the DNCL for five years, extended from the three years at the list's inception. Numbers are now on the list indefinitely.

Overview Legislation entitled Bill C-37, An Act to amend the Telecommunications Act, introduced in the House of Commons, was given first reading on 13 December 2004. It addressed telemarketing calls in Canada and would allow people to sign up to prevent certain telemarketers from contacting them. It received royal assent on 25 November 2005 and came into force on 30 June 2006. The legislation gives the Canadian Radio-television and Telecommunications Commission (CRTC) authority to establish a national do not call list, to establish procedures to administer the Act and to levy penalties for violations. Starting 30 September 2008, residents of Canada were able to register their telephone numbers on the list online, or by telephone, fax or teletype.

Exemptions The Do Not Call List exempts Canadian registered charities, political parties, riding associations, candidates, pollsters and newspapers of general circulation for the purpose of soliciting subscriptions. Telemarketing calls from organizations with whom residents have an existing business relationship are also exempt. Telemarketers may also still call if a resident gave them permission in a written form or verbally. This law also does not extend its protections to non-Canadian phone numbers. Paragraph 41.7(4) of The Telecommunications Act requires that every exempted telemarketer "shall maintain their own do not call list and shall ensure that no telecommunication is made on their behalf to any person who has requested that they receive no telecommunication...". Unlike the DNCL Rules, the Act itself makes no provision for a grace period or expiry, so all do not call requests must be honoured immediately and permanently. In letters dated 27 June 2008, to the Canadian Marketing Association (CMA) and the Canadian Bankers Association (CBA), CRTC Chairman Konrad von Finckenstein personally ruled that do not call requests from third parties, such as iOptOut.ca Archived 3 April 2008 at the Wayback Machine, are to be considered "...as valid requests and must be honoured." Due to its overwhelming popularity, iOptOut.ca is currently being upgraded and improved. On 13 November 2008, the CRTC declined a request from telecommunications provider Rogers Wireless to permit Canadian wireless customers to block unsolicited SMS text messages through the DNCL.

Timeline The privacy benefits the list will achieve remain uncertain. A working group of the CRTC held hearings concerning the planned implementation of the list. It submitted recommendations on 26 July 2006. On 3 July 2007, the CRTC announced it would be issuing a request for proposals to suppliers willing to provide this service. On 21 December 2007, the CRTC announced that it had picked Bell Canada to operate the National Do Not Call List for five years. It is funded from subscription fees paid by telemarketers, rather than relying on fees by end citizens. It became operational on 30 September 2008.

Worked examples

Example 1 — a first encounter with National Do Not Call List

Start with the simplest possible case. Write down what National Do Not Call List claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to National Do Not Call List before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about National Do Not Call List ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of National Do Not Call List

In research
National Do Not Call List appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses National Do Not Call List in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
National Do Not Call List is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2006 establishments in Canada, Privacy in Canada, Telemarketing, so understanding it makes those chapters shorter.
In everyday life
Look for National Do Not Call List outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
