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.

A "contaminant attenuation zone" is a three-dimensional zone that is, * located on land adjacent to a landfilling site, * in the subservice or extends into the subsurface, and * is used or is intended to be used for the attenuation of contaminants from the landfilling site to levels that will not have an unacceptable impact beyond the boundary of the zone. This product requires the use of geographic information system (GIS) software.

The attribute table included in the dataset provides some limited metadata information that is specific to each lake. This includes the: * survey year * survey method * original map scale This dataset should be used for discovery of Bathymetry data. It provides no bathymetric information, but allows users to discover where bathymetry data exists and in what format.

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.

Towers -- structures or buildings that are typically higher than their diameter and high relative to their surroundings -- are shown in this data set. They include: * communication towers * fire towers * microwave towers * radio towers * navigation beacons * lighthouses * lightning locators * meteorological towers

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.

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.

This dataset covers Forest Resource Inventories between 2001 and 2004. It includes: * stand regeneration * harvested trees * trees lost to wildfire, insects, disease or wind damage Information from forest resource inventories provides the basis for major forest resource planning and ministry policy decisions.

Displays areas regulated as a conservation reserve in order to: * permanently protect representative ecosystems, biodiversity and significant elements of Ontario's natural and cultural heritage * provide opportunities for ecologically sustainable land uses, including traditional outdoor heritage activities and associated economic benefits * allow for scientific research and provide points of reference to support monitoring of ecological change on the broader landscape Official GEO title: Conservation Reserve Regulated
