Data Reference Standard On Canadian Provinces And Territories

Introduction

This reference data provides a standard list of values for all Canadian provinces and territories. The list reflects Canada’s 13 major political units. There are many coding systems for Canadian provinces and territories. The data standard shows the relationships among the recommended code and other common codes.

Purpose

This list is intended to standardize the way Canadian provinces and territories are described in datasets to enable data interoperability and improve data quality.

Not included in this standard are previous names, abbreviations and codes for provinces and territories. When changes occur in the future, version history will be maintained.

Applicability

Use of the codes within the “Alpha Code” column is recommended when sharing data within the federal government or publishing data to the Open Government Portal. This alpha code was chosen for three reasons:

1. it is comprehensible for users
2. it is closely aligned with the ISO 3166-2 code for subdivision and is identical to the Canada Post abbreviation
3. it has already been adopted by a number of federal departments

The Alpha Code exactly matches the set of codes created and managed by Canada Post. If Canada Post changes its codes, the Government of Canada will review and separately approve any changes to this reference standard.

If it is necessary to use a numerical code in a data system, then the numerical code created by Statistics Canada is included in the table.
