Legally defined __Municipal__ polygons were drawn from metes and bounds descriptions as written in Letters Patent for Municipalities in the province of British Columbia. In the event of a discrepancy in the data, the metes and bounds description will prevail. Although the boundaries were drawn based on the legal metes and bounds descriptions, they may differ from how regional districts and their member municipalities and electoral areas currently view and/or manage their boundaries. Where discrepancies are noted, the Ministry of Municipal Affairs (the custodian) enters into discussion with the local governments whose boundaries are affected. In order to effect a change to the boundary, Cabinet approval is required. This is done through an Order in Council (OIC). While discrepancies to administrative boundaries are being resolved, boundaries may be adjusted on an ongoing basis until the requested changes are completed. The OIC_YEAR and OIC_NUMBER fields indicate the year that the boundary was passed under OIC and its associated number. The AFFECTED_ADMIN_AREA_ABRVN identifies the administrative areas that are affected by the OIC. See all of the administrative areas currently in the [__Administrative Boundaries Management System (ABMS)__](https://catalogue.data.gov.bc.ca/dataset/12f0fd64-94d5-422a-832e-6627a2a01702). The complimentary [point dataset](https://catalogue.data.gov.bc.ca/dataset/e50b6560-0549-41a6-8035-6b828066692e) that defines the administrative areas is also available.

The spatial representation for an Inventory Region or Compartment. Established by the Resource Inventory Branch, Inventory Regions are large drainages encompassing groups of small drainages also known as compartments. These were once used for planning purposes, similar to the current Planning Cells. They are now maintained in the files as reference for many administration boundaries

Health regions are administrative areas defined by provincial ministries of health. These administrative areas represent geographic areas of responsibility for hospital boards or regional health authorities. Health regions, being provincial administrative areas, are subject to change. For complete Canadian coverage, each of the northern territories as well as the province of Prince Edward Island represents a single health region.

Legally defined __Regional District__ polygons were drawn from metes and bounds descriptions as written in Letters Patent for Regional Districts in the province of British Columbia. In the event of a discrepancy in the data, the metes and bounds description will prevail. Although the boundaries were drawn based on the legal metes and bounds descriptions, they may differ from how regional districts and their member municipalities and electoral areas currently view and/or manage their boundaries. Where discrepancies are noted, the Ministry of Municipal Affairs (the custodian) enters into discussion with the local governments whose boundaries are affected.

The OIC_YEAR and OIC_NUMBER fields indicate the year that the boundary was passed under OIC and its associated number. The AFFECTED_ADMIN_AREA_ABRVN identifies the administrative areas that are affected by the OIC. Please note that the Northern Rockies Regional Municipality appears to be a gap in the Regional District layer, but it is a municipality and can be found in the [Municipalities Layer](https://catalogue.data.gov.bc.ca/dataset/municipalities-legally-defined-administrative-areas-of-bc). A polygon dataset that includes all of the administrative areas currently in the __Administrative Boundaries Management System (ABMS)__ is available [here](https://catalogue.data.gov.bc.ca/dataset/legally-defined-administrative-areas-of-bc).

The Province is divided into nine administrative regions, having a total of 225 wildlife management units (WMU) for the purpose of efficient game management.

In 2021, the Canada Coast Guard (CCG) and Fisheries and Oceans Canada updated its administrative boundaries following the creation a new Arctic region. There are now 4 administrative regions in CCG (Western, Arctic, Central and Atlantic). DFO and Coast Guard Arctic Regions developed these regions in partnership with the people they serve; this important decision will lead to stronger programs and services to better meet the unique needs of our Arctic communities. DFO and CCG operations and research cover Canada's land and waters to the international boundaries (EEZ) and are in no way limited to the boundaries drawn in the map.

Small area data (SAD) on field crops show seeded and harvested area, yield and production estimates for most principal field crops and some special crops in Canada. Most SAD geographies correspond exactly with the Census Agriculture Region (CAR) limits, excepts for some regions of Quebec (where small areas are defined by provincial administrative boundaries), Saskatchewan (where small areas coincide with census divisions boundaries as of 2017) and British Columbia.For exact correspondence between Census Agricultural Regions (CAR) and Small Area Data (SAD) Regions, see the following link:https://www.statcan.gc.ca/eng/statistical-programs/document/3401_D2_V2These regions are associated with Statistics Canada estimates on principal field crops available in the following table: https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=3210000201

Provides a provincial coverage of the administrative boundaries of the regional health authorities (2) in New Brunswick to promote the use of a common geographic representation in New Brunswick. The health regions in New Brunswick are groupings of the NBHC Community Boundaries (as defined by the NBHC), which are groupings of the municipalities (Census subdivisions).

In 2021, the Canada Coast Guard (CCG) and Fisheries and Oceans Canada (DFO) updated its administrative boundaries following the creation a new Arctic region.There are now 7 administrative regions in DFO (Pacific, Arctic, Ontario and Prairie, Quebec, Gulf, Maritimes, Newfoundland and Labrador). DFO and Coast Guard Arctic Regions developed these regions in partnership with the people they serve; this important decision will lead to stronger programs and services to better meet the unique needs of our Arctic communities.DFO and CCG operations and research cover Canada's land and waters to the international boundaries (EEZ) and are in no way limited to the boundaries drawn in the map.

The spatial representation of the 5 Mining Regions for the Ministry of Energy, Mines and Low Carbon Innovation (EMLI). These administrative boundaries are derived from the 8 __[Natural Resource (NR) Regions](https://catalogue.data.gov.bc.ca/dataset/dfc492c0-69c5-4c20-a6de-2c9bc999301f)__ (https://catalogue.data.gov.bc.ca/dataset/dfc492c0-69c5-4c20-a6de-2c9bc999301f).
