This dataset provides a summary of annual air pollution statistics from 1995 to the current available year for six air pollutants: * Carbon Monoxide * Oxides of Nitrogen (NO, NO2, NOx) * Ozone * Fine Particulate Matter (PM2.5) * Sulphur Dioxide * Total Reduced Sulphur The annual statistics...

The Ministry of the Environment, Conservation and Parks started a project to characterize the number of species of bumble bees and the relative abundances of these species in southwestern Ontario in support of the Pollinator Health Action Plan. Bumble bees were collected from 46 locations to...

The Ministry of the Environment, Conservation and Parks, with assistance from the Ontario Ministry of Agriculture, Food and Rural Affairs, started the Pollen Monitoring Network in 2015, in support of Ontario's Pollinator Health Action Plan. This was to measure changes in pesticide (neonicotinoid...

A tank is an above ground container that holds either petroleum or water. This data is no longer being updated. It is best suited for historical research and analysis.

This dataset contains linear features constructed by beavers. The linear features are captured to scale on: * single line rivers * lakes * double line rivers We are no longer updating this data. It is best suited for historical research and analysis.

This dataset was created to establish a permanent boundary. Lands within this boundary are subject to the principles contained in the Oak Ridges Moraine Legislation. Boundary is complete as of October, 2001.

Waterbody types include: * Lake * River * Canal * Reservoir * Kettle lake * Pond * Beaver Pond * Ocean Instructions for downloading this dataset: * select the link below and scroll down the metadata record page until you find Transfer Options in the Distribution Information section, * select the...

Watercourses are line features - natural or manmade - that represent the location of flowing surface water. This product requires the use of GIS software. *[GIS]: geographic information system

Shows areas where the health and prevalence of caribou can be linked to the attributes of the land that supports them. Ontario's Woodland Caribou Recovery Strategy (2008) provides advice and recommendations on the approaches needed for the recovery of Woodland Caribou. The strategy recommends the...

Includes: * contour land * contour land approximate * contour land auxiliary/interpolated * contour land depression In southern Ontario the contour interval is 5 meters. In the near north the contour interval is 10 meters. In the Far North the contour interval depends on the information source....

The OHN is a provincial medium scale originating from data with regional scales of 1: 10,000 in Southern Ontario, 1: 20,000 in Northern Ontario and 1: 50,000 in the Far North. The shoreline is taken from the OHN - Waterbody data class. This data is used for cartographic purposes and web mapping...

The flood magnitude statistics can be used for applications such as flood plain delineation and design of hydraulic structures. The drought severity statistics can be used for applications such as water abstraction and effluent dilution.

The Baseline hydrology statistics (stream flow regime) in the Southwestern Hudson Bay and Nelson River watershed systems were produced for the Water Survey of Canada's HYDAT database. These baseline statistics provide information on the water quantity at each Water Survey Canada gauge location ....

This dataset consists of man-made point features in a transportation network. Transport point features include: * Culvert Railway Symbolized - a enclosed drain under a railway * Culvert Roadway Symbolized - an enclosed drain under a roadway * Turntable Railway - a rotatable platform with a track,...

Shows areas where forest insect pests have damaged or killed trees by defoliation, foliage mining and wood boring. Tree mortality rarely occurs as the result of one year's infestation, but from the result of several consecutive years of infestation and other contributing factors affecting...

This dataset combines: * Far North Land Cover * Southern Ontario Land Resource Information System * Provincial Land Cover 2000 Edition While each of these source products has different pixel resolutions, projections and classifications, the combined OLCC data set is a standardized product. It has...

The dataset represents prominent linear (man-made or natural) features including: * cliffs * dykes * fences * walls * hedgerows * feature outlines * racetrack centre lines * racetrack edges We are no longer updating this data. It is best suited for historical research and analysis.

The Digital Elevation Model (DEM) data is organized into 20km x 20km tiles with a spatial resolution of 5m. This data is intended to be used for pre-engineering survey and design as well as the production of planimetric mapping at differing accuracies. This data is intended for GIS and remote...

This dataset contains miscellaneous point features including: * mine head frames * cadastral iron bar (a type of survey monument) * historical monuments * horizontal control monuments * mile posts * smoke stacks We are no longer updating this data. It is best suited for historical research and...

This dataset contains manmade linear features in a transportation network, such as bridges and railway tunnels. It does not include roads. The linear features included are: * aerial cable ways * railway bridges * roadway bridges * railway and road bridges * pedestrian/cycle bridges * railway...
