Notice No. DGRB-009-07 — Industry Canada Converting from NAD27 to NAD83

This Notice announces an administrative change to Industry Canada's Spectrum Management System Database.

In the past, Industry Canada has calculated geographic co-ordinates (in terms of latitude and longitude) for radio station licences and broadcasting certificates, on the basis of a standard known as North American Datum of 1927 (NAD27). This standard has been updated and replaced by a standard known as North American Datum 1983 (NAD83). Effective January 19, 2008, Industry Canada will migrate its Spectrum Management System Database as well as all existing radio station licences and broadcasting certificates to the NAD83 standard.

Schedules IV, V and VI of the Radiocommunication Regulations specify certain geographic areas, identified through the use of geographic co-ordinates, for the purpose of defining what constitutes metropolitan areas as well as high, medium and low congestion zones. As this is an administrative change rather than a regulatory one, these schedules will not change. However, effective January 19, 2008, Industry Canada will apply the schedules using the NAD83 standard.

The conversion to the NAD83 standard will also have minor impacts on coordination zones, district office boundaries and other areas where geographic co-ordinates are used in managing the radiocommunication and broadcasting spectrum.

Most radio station licensees and broadcasting certificate holders will have new geographic co-ordinates appear on their licences and certificates respectively.

While Industry Canada will not be issuing replacement documents, radio station licensees wishing to obtain revised copies of their licences may do so by visiting Industry Canada's Spectrum Direct website at: http://www.ic.gc.ca/eic/site/sd-sd.nsf/fra/accueil.

Broadcasting certificate holders may obtain revised certificates by contacting:

Head, Certification, Planning and Operation,
Radiocommunications and Broadcasting Regulatory Branch,
613-998-2914 or
by email at: kinross.debbie@ic.gc.ca.

Clients applying for new licences or certificates may use co-ordinates on maps using either the NAD27 or the NAD83 standards, but should note that the resulting licences and certificates will bear co-ordinates based on NAD83.

Clients, downloading or otherwise obtaining data from Industry Canada's online databases, should be aware that, effective January 19, 2008, the data will be in the NAD83 format.

Should you have any questions regarding this administrative change, please contact your local spectrum management office. Contact information can be found on Industry Canada's Spectrum Management and Telecommunications website, in Radiocommunication Information Circular 66 (RIC-66) at: http://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf01742.html.
