| Notes: 1. Regional integrated health authorities came into effect March 1, 2005. |
|||||
| 2. In Prince Edward Island, the four health regions were abolished in November 2005 as a result of health system restructuring. These boundaries have been maintained for the release of indicators from 2005 Canadian Community Health Survey. | |||||
| 3. In Nova Scotia, health zones are aggregations of the nine district health authorities (DHA). | |||||
| 4. Public health units (PHU) administer health promotion and disease prevention programs. District health councils (DHC) were advisory, health planning organizations. The DHCs were dissolved as of March 31, 2005. The Ontario Ministry of Health and Long-Term Care announced the creation of Local Health Integration Networks (LHIN) on April 1, 2005. LHINs are responsible for planning, funding and administering health care programs and services across the province. | |||||
5. For most data sources (with the exception of Census and Demographic population estimates), health region level data are not available for some northern health regions in Manitoba and Saskatchewan which have small populations. To avoid suppression in these areas where small numbers or sample size impact on data quality, data have been grouped with neighbouring regions, as follows: Churchill Regional Health Authority, Manitoba (4690) is combined with Burntwood Regional Health Authority (4680) and referred to as 'Burntwood/Churchill' (4685); and, Athabasca Health Authority (4713) Saskatchewan is combined with Mamawetan Churchill River Regional Health Authority (4711) and Keewatin Yatthé Regional Health Authority (4712) and referred to as 'Athabasca/Keewatin/Mamawetan' (4714). |

| 6. In Alberta, a change effective December 2003, affected the boundary between Calgary Health Region and the David Thompson Regional Health Authority. | |||||
