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.

This data set shows utility points that provide services for: * power * water * communications * heating fuel They include: * fibre optic stations * hydro stations * lock pumping stations This product requires the use of geographic information system (GIS) software.

Data set contains geographical referencing information like: * type of feature or place * location coordinates * geographic township * municipal and map references Also contains places and background information behind their official naming like: * name status * naming date * name origin * naming history This layer used to be distributed under the name "Geographic Name Extent" but was modified to "Geographic Named Extent" in November 2011.

Data has been collected primarily using a depth measurement device, such as an echo-sounder, in combination with a Global Positioning System (GPS) for horizontal positioning. Other survey methods, such as bathymetric LiDAR may also have been used. The survey method used in each body of water is shown in the [Bathymetry Index](https://geohub.lio.gov.on.ca/datasets/mnrf::bathymetry-index ).

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.

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).

The spatial record for all the province's geographic areas affected by provincial level, area-specific land use policy. This layer may contain geometry from the: * provincial parks-regulated layer * conservation reserves-regulated layer * natural heritage values area layer *  wilderness areas layer * crown land MNR acquisitions layer * crown land MNR unpatented layer * CLUPA geometry (enhanced management areas and general use areas) layer Not to be used as a source of protected areas (provincial park, conservation reserve, etc.), crown land or private land boundaries. Official GEO title: CLUPA Provincial

This dataset shows the boundaries of the province's six fire management zones that existed prior to 2014 in which most forest fires received the same type of response. These management zones were based on: * common forest and forest fire management objectives * land use * density of values at risk * fire load * forest ecology The 2014 Wildland Fire Management Strategy moved from a zone-based approach to one where each wildland fire is assessed and receives an appropriate response according to the circumstances and condition of the fire.

The dataset has been used for the Great Lakes Conservation Blueprint Project for Aquatic Biodiversity. It can be used for: * research and aquatic species inventories * environmental impact and monitoring * watershed based resource planning and management * fisheries and other aquatic analysis Official GEO title: Aquatic Ecosystems Classification: Great Lakes Basin - Coast, Streams, Lakes and Wetlands

This new data class brings over data from the Waste Management Information System (WMIS), which is a Microsoft Access based database used by the Ministry of Natural Resources (MNR) to track Waste Management Sites. This was married with the spatial data from Waste Disposal Sites where possible Different Waste Disposal Site types collected by the Ministry of Natural Resources include: * Compost Disposal * Hazardous Waste Disposal * Household Waste Disposal * Industrial Waste Disposal * Septic Drying Bed * Septic Field * Sewage Disposal * Tile Bed * Transfer Station This product requires the use of geographic information system (GIS) software.
