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 dataset consists of man-made point features in a transportation network. Transport point features include: * Culvert Railway Symbolized - a enclosed drain under a railway * Culvert Roadway Symbolized - an enclosed drain under a roadway * Turntable Railway - a rotatable platform with a track, used to turn locomotives and cars We are no longer updating this data. It is best suited for historical research and analysis.

Shows areas where forest insect pests have damaged or killed trees by defoliation, foliage mining and wood boring. Tree mortality rarely occurs as the result of one year's infestation, but from the result of several consecutive years of infestation and other contributing factors affecting weakened trees (e.g., fungal invasion). The Government of Ontario tracks forest damage events to help proactively manage the detrimental effects to our forests.   We monitor the threat and spread of invasive forest pest insect species in Ontario. The data is also important to the Forest Management Planning process in calculating timber volume loss within affected areas This product requires the use of geographic information system (GIS) software.

This data is used for referencing spatial and tabular Forest Resource Processing Facility information. Each facility has one or more processing sites, each dedicated to processing resources for a specific purpose. For example, a pulp, paper and paperboard facility has one processing site to produce pulp, and another one dedicated to producing paper. All facilities that use 1,000 cubic metres or more of forest resources in one year must have a facility licence. This data class has been remodeled in 2014 to make it more flexible as a stand-alone product.

This spatial dataset represents the locations of aquatic resource area (ARA) survey points. ARA survey points 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 licences 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).

Natural areas abutting Lake Simcoe are areas of a continuous vegetation community class that have a minimum size of 1 ha and are wholly or partially within the 30 m buffer zone of the Lake Simcoe shoreline. These areas may be a narrow band of vegetation along the shoreline or larger areas, which extend a greater distance from the shoreline. As described in policy 6.31-SA, the MNR and the MOE will map the location of natural areas abutting Lake Simcoe.

Shows areas where the health and prevalence of caribou can be linked to the attributes of the land that supports them. Ontario's Woodland Caribou Recovery Strategy (2008) provides advice and recommendations on the approaches needed for the recovery of Woodland Caribou. The strategy recommends the identification of ranges and local populations to: * maintain existing, self-sustaining, genetically-connected local populations of caribou * ensure security for and (reproductive) connections among currently isolated mainland caribou * re-establish caribou in strategic areas to create self-sustaining local populations and ensure connectivity Instructions for downloading this dataset: * select the link below and scroll down the metadata record page until you find **Transfer Options** in the **Distribution Information** section, * select the link beside the **Data for download** label, * you must provide your name, organization and email address in order to access the dataset This product requires the use of GIS software. *[GIS]: geographic information system

A feature is a representation of a real world object, such as a lake, stream, dam or rapid. There are three hydrographic feature classes:  points, lines and polys. All may impede or be hazardous to waterflow and/or navigation on a watercourse or waterbody. This data shows natural and manmade point features. Examples include: * waterfalls * rapids * rocks * Sea Lamprey barriers * shipwrecks This product requires the use of geographic information system (GIS) software.

The Agricultural Resource Inventory 1983 (ARI 1983) dataset includes agricultural land use and drainage systems information. This dataset evaluates the mix of crops and classifies them into different categories which are valid over a long period of time. Mapping these systems provides an overview of the location, quantity and quality of the use of agricultural land in southern Ontario. Used by farmers, land use planners, municipal officials, policy makers and the general public. This dataset is no longer collected or maintained. Information and data held by the Ontario Ministry of Agriculture, Food and Agribusiness for this record is historical.

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.
