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.

The purpose of this dataset is to depict the boundaries of the Niagara Escarpment Plan. The outer boundary of the area covered by the Niagara Escarpment Plan is fixed and inflexible. It can only be changed by a plan amendment. It is formed by a combination of features like: * roads * railways * electrical transmission lines * municipal and property boundaries * lot lines * rivers * other topographic features [More information](http://www.escarpment.org)

The Ontario Radar Digital Surface Model (DSM) has the following features: * source data: 1 arc second spaceborne C-Band Interferometric Synthetic Aperture Radar (IFSAR) data * Ministry of Natural Resources (MNR) Lambert Conformal Conic Projection * vertical datum in both EGM96 and CGVD28, separately * elevation value: floating * local Polynomial Interpolation from vector elevation points * spatial resolution: 30 meter * asurface elevation model This product offers significant advancements in elevation data in the province. [Read the details about these advancements and other technical specifications,](https://geohub.lio.gov.on.ca/maps/mnrf::ontario-radar-digital-surface-model/) including data processing, major spatial characteristics of the Radar DSM, and the steps to generate the Northern Ontario Radar DSM.

Rivers included in this map series include: * Albany * Winisk * Severn * Moose * Ekwana * Attawapiskat The maps display gauging systems such as cost share agreement gauges, Water Survey of Canada gauging stations and Meteorological Survey of Canada Climate stations. Dams, their jurisdictional owners and Far North First Nations communities are included.

Depicts the internal boundaries of the Niagara Escarpment Plan area. The 7 land use designations are: * escarpment natural area * escarpment protection area * escarpment rural area * [minor urban centre](/dataset/minor-urban-centres-in-the-niagara-escarpment-plan) * urban area * escarpment recreation area * mineral resource extraction area The land use designations represent the internal boundaries between designations within the Niagara Escarpment Plan. These internal boundaries are not intended to be site-specific and should not be used for accurate measurements. The exact delineation of designation boundaries on specific sites will be done by the implementing body through the application of the designation criteria as outlined in Part 1 of the Niagara Escarpment Plan, utilizing the most detailed or up-to-date information available and site inspection.

The Niagara Escarpment Special Policy Area is comprised of the North Aldershot Policy Area and the Waterdown Policy Area. [More information](http://www.escarpment.org)

Minor urban center is one of the 7 Niagara Escarpment Plan land use designations. This designation includes rural settlements, villages and hamlets. The boundaries of minor urban centres are defined by the municipality in an approved official plan and/or secondary plan. [More information](http://www.escarpment.org)

A synthesis of available background data on the types and extent of anthropogenic disturbances on this shoreline as a well as to understand the types and amount of remaining natural shoreline features.

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).

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.
