Canada’s landmass is very diversified and comprises 7 distinctive areas called physiographic regions, each of which has its own unique topography and geology. Physiographic regions are large areas that share similar relief and landforms shaped by common geomorphic processes and geological history. Physiographic regions are often used to describe Canada’s geography to show regional differences in climate, vegetation, population and the economy.This dataset collection contains three interrelated datasets mapping the location of Canada’s 7 different physiographic regions, their 21 subregions and many divisions (landforms).

This is a polygon feature class representing large, named, physiographic features (areas) in the province, e.g., mountains, mountain ranges, ridges, plateaus, hills, and valleys.

Ecodivisions are areas of broad climatic and physiographic uniformity, defined at the continental level.

Ecosections are areas with minor physiographic and macroclimatic or oceanographic variations. There are 114 ecosections in British Columbia varying from pure marine units to pure terrestrial units. Ecosections are meant to be mapped at small scales (1:250,000) for resource emphasis and area planning

The Yukon Territory is underlain by a great variety of rock types ranging in age from Early Proterozoic to Recent and representing diverse environments including epicratonic basins, subsiding shelves, foreland basins, island arcs and deep ocean basins. Episodes of compressional and extensional deformation, transcurrent faulting, metamorphism and plutonism further complicate the map pattern. This complex geological record has been described in terms of the interactions of several terranes (large parts of the earth's crust which preserve a common geological record) with each other and with the margin of ancestral North America.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

The __shíshálh Nation__ contains legally defined areas of land within the Province of British Columbia over which the shíshálh Nation exercises self-government, including the administration of resources and services available to its members, as described in the shíshálh Nation Self-Government Act of 1986. This spatial layer contains multipart features. Note that the name of the spatial layer is outdated; after the notification of retirement of the layer has been circulated the dataset will be recreated with the correct name. The source data for the geometry of the parcels was the federal "GeoBase - Aboriginal Lands" dataset, available under OGL - Canada. Parcels were adjusted to match provincial base mapping features, following the metes and bounds descriptions in the Letters Patent. 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). A complimentary point dataset that defines the administrative areas is also available [here](https://catalogue.data.gov.bc.ca/dataset/legally-defined-administrative-areas-of-bc-boundary-locations).

Legally defined __Local Trust Area__ polygons were drawn from metes and bounds descriptions as written in Letters Patent for the Local Trust Areas in the province of British Columbia.

The __Counties of British Columbia__ contains areas of land within the Province of British Columbia representing legally defined administrative areas described in the County Boundary Act. The purpose of this division is for the administration of justice. The counties were delineated using provincial base mapping features, following the metes and bounds descriptions in the Letters Patent.

Legally defined __Electoral Area__ polygons were drawn from metes and bounds descriptions as written in Letters Patent for Regional District Electoral Areas 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.
