Get mapping data related to the Northwest Greater Toronto Area Transmission Corridor Identification Study. In June 2019, the Ministry of Energy, Northern Development and Mines along with Ontario’s electricity system planner, the Independent Electricity System Operator, launched the Northwest GTA Transmission Corridor Identification Study to identify an appropriate corridor of land for use by future power lines if and when the need arises.

Fish Habitat Type Data for Ministry of Natural Resources and Forestry's Parry Sound District used for fisheries management.

Historical Oil Fields are subsurface accumulations or 'pools' of crude oil designated as such for the purposes of the Oil, Gas and Salt Resources Act. This product requires the use of geographic information system (GIS) software.

## GIS data containing the boundaries of Provincially Significant Employment Zones in the Greater Golden Horseshoe as identified by the Minister of Municipal Affairs and Housing As areas of high economic output, provincially significant employment zones are strategically located to provide stable, reliable employment across the Greater Golden Horseshoe region. They provide opportunities to improve coordination between land use planning, economic development, and infrastructure investments to support investment and job creation over the longer-term.

Crown Game Preserves were established to prohibit or regulate the hunting and trapping of wildlife in specific areas to restore local populations.

Get data on provincially tracked species locations generalized to a 1km by 1km grid. This spatial dataset contains generalized location data for: * species of conservation concern (including species at risk) * plant communities * wildlife concentration areas. The data includes a spatial layer and related table. We recommend using the geodatabase, as the relationship between the spatial layer and its table is built in. If you prefer another format, the ‘complete shapefile’ download is the only option that includes the spatial layer and its related table in one package. This data can be used to identify species or ecological communities on or near your property or project site.

This spatial dataset represents the boundaries of areas designated under the [Aggregate Resources Act, R.S.O 1990](https://www.ontario.ca/laws/statute/90a08) where a licence or permit is required for aggregate extraction. Under the Act, all aggregate operations must be licensed on private land or permitted on Crown land. Use our interactive [Pits and Quarries map](https://www.ontario.ca/page/find-pits-and-quarries) to find aggregate designated areas and authorized sites.

A spot height identifies the elevation (z value) above sea level of natural and man-made geographic features. It includes: * spot heights * vertical control points * water level/lake elevations This product requires the use of geographic information system (GIS) software.

This spatial dataset represents the locations of aquatic resource area (ARA) line segments derived from corresponding line features in the Ontario Hydro Network. ARA line segments may represent a portion of a water body or an entire water body (such as a lake, river or stream). Attributes for each location may include: * physical characteristics such as water temperature and depth * fish species The ARA data classes are the authoritative source for generic spatial data related to fish species in Ontario. The data can be used for: * forest and fisheries management planning * municipal planning * natural heritage and land use planning * issuing work permits under the [Public Lands Act](https://www.ontario.ca/laws/statute/90p43), 1990 * issuing licenses under the [Fish and Wildlife Conservation Act](https://www.ontario.ca/laws/statute/97f41), 1997 * fulfilling public information requests There are additional sensitive data related to provincially tracked species and species at risk that are not available as part of this open data package. Distribution of sensitive species data is approved on a need-to-know basis. Requests should be sent to [geospatial@ontario.ca](mailto:geospatial@ontario.ca).

This dataset covers Forest Resource Inventories between 2001 and 2004. It includes: * stand regeneration * harvested trees * trees lost to wildfire, insects, disease or wind damage Information from forest resource inventories provides the basis for major forest resource planning and ministry policy decisions.
