Overview

The Postal CodesOM by Federal Ridings File, Special Issue (PCFRF Special Issue) is a digital file that provides a link between the six-character postal codeOM and Canada's federal electoral districts (which are also known as federal ridings). This special version of the PCFRF links 848,257 active postal codeOM records, existing as of June 2013, to the 338 federal electoral districts of the 2013 Representation Order.

Elections Canada defines a federal electoral district (FED) as any place or territorial area entitled to return a Member of Parliament (MP) to serve in the House of Commons. Federal electoral district legal limits and descriptions are the responsibility of the Chief Electoral Officer, and are usually revised every 10 years after the results of the decennial census. There are 338 FEDs in the 2013 Representation Order, the most recent revision of the federal electoral district limits. The FEDs are based on the 2011 Census population data. These new federal electoral districts will be applied in the first general election called after May 1, 2014.

For more information on the redistricting process, please refer to the Elections Canada website.

Methodology for creation of Special Issue File

The Postal CodesOM by Federal Ridings File, Special Issue was created by converting the existing federal electoral districts (2003 Representation Order) and their linked postal codesOM to the new federal electoral districts (2013 Representation Order), transferring the postal codeOM linkages. The conversion process was accomplished using 2011 Census Dissemination Blocks and a best fit methodology for dissemination blocks that were found in more than one federal electoral district. During the conversion process, in cases where dissemination blocks overlapped two or more federal electoral districts (2013 Representation Order), a complete allocation was made of the dissemination block to one FED based on the population count or the area of the dissemination block found in each FED.

Postal codesOM linked to more than one federal electoral district, 2013 Representation Order

As is the case with the 2013 version of the standard product Postal CodesOM by Federal Ridings File (2003 Representation Order), postal codesOM can and are linked to more than one FED. In such cases, a 'weight' has been established in order to provide an indicator of the magnitude of overlap.

The 'weight' estimates the proportion of the population of a postal codeOM that resides within each FED. If a postal codeOM is linked to only one FED in the PCFRF, the weight is equal to 1. If the postal codeOM is linked to more than one FED and is reported in the 2011 Census, the weight is equal to the proportion of the population that reported the postal codeOM in each of the FEDs. If the postal codeOM was not reported in the census, the weight is estimated using the address ranges in the service area of the postal codeOM. If necessary, the weights for a postal codeOM are normalised and adjusted using the single link indicator variable in the PCCF so that the sum of weights equals 1.0.
