The purpose of this dataset is to identify the location of river valley connections.

This dataset consists of information from reports received by the Spills Action Centre (SAC). They are generated and completed by SAC following the initial report of a spill. The data includes: * the reference number assigned to the spill * the municipality in which the spill occurred * what was impacted (e.g. land, water, air, or combination) * the substance being discharged (e.g. oil, gases, chemical, etc.) * whether the environmental impact is confirmed, possible, or not anticipated, and * the source/sector of the spill. The data reflects the information as reflected in the report, following the incident. All spills reported to SAC are recorded in the database, regardless of whether or not the Ministry provides field response.

To identify the Greenbelt Area as defined by the Greenbelt Act, 2005. The outer boundaries of Greenbelt area includes the lands within: * Niagara Escarpment Plan * Oak Ridges Moraine Conservation Plan * Lands designated as Protected Countryside * Lands designated as Urban River Valley

Concentration levels from soil sampled in urban and rural parklands in the province. Data includes: * station name and location (rounded to 1 km precision) * sample date * results for 35 inorganics (1991) * results for 8 volatile organic compounds (2009)

The data contains the following mapping layers from the Oak Ridges Moraine Conservation Plan: * Oak Ridges Moraine Conservation Plan outer boundary * Oak Ridges Moraine Conservation Plan designations, including: * natural core area * natural linkage area * countryside area * rural settlement * Palgrave Estates residential community * settlement area The data also contains associated policy designation mapping.

This data shows the component parts of the Greenbelt Area as set out in the Greenbelt Act, 2005. * There are currently four designations: * Niagara Escarpment Plan * Oak Ridges Moraine Conservation Plan * Protected Countryside * Urban River Valley

Designed to represent true ground and bathymetric elevation, this digital elevation model (DEM) covers two sections of the Greater Toronto Area (GTA) along the western shoreline of Lake Ontario: * Hamilton in the west to Niagara-on-the-Lake in the east * Scarborough in the west to Port Hope in the east

Crown Game Preserves were established to prohibit or regulate the hunting and trapping of wildlife in specific areas to restore local populations.

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.

Wetlands are lands that are seasonally or permanently flooded by shallow water. They also include lands where the water table is close to the surface. The wetland polygons are managed independently from other hydro data classes and may overlap water bodies or other hydro data. Not all wetlands have been identified and mapped. Active maintenance is ongoing province wide. The currency and accuracy of the spatial representation is variable and requires on-the-ground verification.
