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.

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.

Bathymetry line data was collected to assess fish habitat in Ontario. Spot depths (bathymetry points) were used to measure the depth contours, which function like isobars to show lines of constant depth. Their density and positional accuracies vary depending on the survey style and parameters. This data should never be used for navigation.

Get data on the results of a community led planning process to sustain the natural environment in Frontenac, Lanark, Leeds & Grenville. This dataset represents the results of a community led planning process to sustain the natural environment across the landscape. A collaborative team of individuals representing governments, stewardship councils, conservation organizations and private landowners worked together to identify and map natural heritage features and the connections between them. The data package includes: * spatial data * project reports * presentation materials The data has been made available to inform and support: * land use planning and resource management decision-making * strategic priorities for stewardship and restoration projects * priorities for conservation land acquisitions * priorities for inventory programs and research projects

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.

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 ).

Wildlife Management Units are used for a number of wildlife management purposes, like indicating the areas of Ontario where hunting open seasons and harvest quotas apply. Wildlife Management Unit boundaries are regulated under the Fish and Wildlife Conservation Act - Ontario Regulation 663/98, Part 6 as amended.

Includes: * National Parks * National Marine Conservation Areas * heritage canals * National Wildlife Areas * Other Federal Protected areas This dataset is provided by the federal government, and may not include all Federal protected lands.

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.
