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.

Get information on research plots for the Guide Effectiveness Monitoring Program This dataset includes ecological information for Guide Effectiveness Monitoring (GEM) Program site locations. The GEM Program evalutes the effectiveness of forest management guides on songbird occupancy rate and community structure. Learn about the procedures and protocols used for this study in the [Centre for Northern Forest Ecosystem Research Technical Report 004: Effectiveness Monitoring of Forest Management Guides](https://www.ontario.ca/page/catalogue-natural-resource-scientific-and-technical-publications).

Ontario's Crown forest is divided into geographic planning areas, known as forest management units. Most of these units are managed by individual forest companies under a Sustainable Forest License. A forest management unit is identified by an assigned official name (e.g., Black Spruce Forest) and a unique numeric code. Before any forestry activities can take place in a management unit, there must be an approved forest management plan in place for each management unit.

These signs serve a variety of purposes ranging from providing general information and safety warnings, to enforcement and land management notices to the general public. Ministry of Natural Resources (MNR) signs are erected to support and enforce such provincial acts as the: * Fish and Wildlife Act * Public Lands Act This product requires the use of geographic information system (GIS) software.

This spatial dataset represents the locations of aquatic resource area (ARA) polygon segments derived from corresponding polygon features in the Ontario Hydro Network. ARA polygon 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 observed The ARA data classes are the authoritative source for generic spatial data related to fish species in Ontario. The data may be used for: * forest and fisheries management planning * municipal planning * natural heritage and other 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).

Fish Culture Operation MNR identifies the locations of the Ontario Ministry of Natural Resources (MNR) fish culture stations (or hatcheries) and sub- stations. The data set outlines their property boundaries. This product requires the use of GIS software.

Hazardous forest types for wildland fire means forest types assessed as being associated with the risk of high to extreme wildland fire. This data is intended to help inform where further assessment is required and is to be used in conjunction with guidance from the Ministry of Natural Resources and Forestry .

This dataset provides various Ministry of Natural Resources and Forestry business areas with fundamental forest inventory information needed to meet their program mandates.

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.

Ministry of Natural Resources (MNR) regions are divided into districts - smaller organizational units - to help manage ministry programs and resources. Extents of the districts were originally compiled by description of: metes and bounds, topographic features, geographic township boundaries, territorial district boundaries, etc. Changes to the extent of the districts have been made over time by MNR district offices. This product requires the use of geographic information system (GIS) software.
