The Federal Electoral Districts (FED) dataset is a digital representation of the 343 electoral districts proclaimed by the 2023 Representation Orders. Canada is divided into 343 federal electoral districts. A representative or member of Parliament is elected for each electoral district. Following the release of population counts from each decennial census, the Chief Electoral Officer determines the number of seats in the House of Commons and publishes the information in the Canada Gazette. Electoral boundaries commissions then determine the adjustments to the constituency boundaries. The federal electoral boundaries commissions are independent bodies that make all decisions regarding the proposed and final federal electoral boundaries. Elections Canada provides support services to the boundaries commission in each province. Based on reports from these commissions, the Chief Electoral Officer prepares a representation order that describes the boundaries and specifies the name and the population of each FED. The 2023 Representation Order (proclaimed on September 22, 2023) was based on 2021 Census population counts, and increased the number of FEDs to 343, up from 338 from the previous 2013 Representation Order. Alberta received three additional seats while Ontario and British Columbia each gained one seat. The representation order is in force on the first dissolution of Parliament that occurs at least seven months after its proclamation (on or after April 23, 2024). The names of FEDs may change at any time through an Act of Parliament.

The Postal Code Project is responsible for linking the approximately 900,000 single postal codes in Canada to Statistics Canada’s Census dissemination geography, (presently 2021 Census geography). This process is performed by using data provided by Canada Post Corporation and linking to Census Dissemination geography via the process of geocoding. The result is the creation of the Postal Code Conversion File (PCCF) which provides a correspondence between the six character postal code and Statistics Canada’s standard geographical areas, and also the Postal Codes by Federal Ridings File (PCFRF) which provides a link between the six character postal code and Canada’s federal electoral districts.
