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.

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)

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

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

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.

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

Miscellaneous events are often the result of the cumulative impact of a combination of abiotic, insect and disease agents or events. For example, Aspen decline where repeated infestations of Forest Tent Caterpillar, are combined with several seasons of prolonged drought. 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.

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.

Statistics include the flood magnitude with the following recurrence intervals: * 1:2 years * 1:2.33 years * 1: 5 years * 1:10 years * 1:20 years * 1:25 years * 1:50 years * 1:100 years * 1:200 years * 1: 500 years These flood statistics can be used for applications such as floodplain delineation and the design of hydraulic structures.

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).
