Health Regions: Boundaries and Correspondence with Census Geography
Health regions and peer groups
"Health region" refers to administrative areas defined by the provincial ministries of health. For complete Canadian coverage, each of the northern territories also represents a health region.
Health region boundary changes
- In Quebec, there was a reassignment of 32 Census subdivisions from Région de la Montérégie to Région de l’Estrie.
- In Alberta, there was a reassignment of 44 dissemination blocks.
For more detailed information, see Appendix 4A Detailed list of 2015 changes in Quebec and Appendix 4B Detailed list of 2015 changes in Alberta.
The boundaries, health region codes and health region names in the remaining provinces and territories have not changed.
See the following tables for history of changes since 2000:

Health region peer groups
In order to effectively compare health regions with similar socio–economic characteristics, health regions have been grouped into 'peer groups'. Statistics Canada used a statistical method to achieve maximum statistical differentiation between health regions. Twenty–four variables were chosen to cover as many of the social and economic determinants of health as possible, using data collected at the health region level mostly from the Census of Canada. Concepts covered include:
- basic demographics (for example, population change and demographic structure),
- living conditions (for example, socio-economic characteristics, housing, and income inequality), and
- working conditions (for example, labour market conditions).
Peer groups based on 2015 health region boundaries and 2011 Census of Population and 2011 National Household Survey data are available. There are currently nine peer groups identified by letters A through I. There have been no changes made to peer group assignments since 2014.
A more detailed discussion on the rationale and methods involved in the development of peer groups is available in Health Region (2014) Peer Groups – Working paper.
