Municipal Parks are public lands set aside for recreation purposes or to protect natural and cultural environments. We are no longer updating this data. It is best suited for historical research and analysis.

This spatial dataset represents the boundaries of the areas of responsibility for aggregate inspectors working on behalf of the Ministry of Natural Resources and Forestry. In southern Ontario, inspectors may use various criteria to determine their area of responsibility, including: * geographic...

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...

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...

This dataset shows the boundaries of the province's six fire management zones that existed prior to 2014 in which most forest fires received the same type of response. These management zones were based on: * common forest and forest fire management objectives * land use * density of values at...

Built-Up Areas are man-made land cover features, ranging from small hamlets at rural cross roads to large cities. 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 *...

A spot height identifies the elevation (z value) above sea level of natural and man-made geographic features. It includes: * spot heights * vertical control points * water level/lake elevations Instructions for downloading this dataset: * select the link below and scroll down the metadata record...

Bathymetry is the measurement of water depth in lakes. From the 1940s to the 1990s, the Ministry of Natural Resources and Forestry produced bathymetry maps for over 11,000 lakes across Ontario. The data can be used by the general public and GIS specialists for: * climate change modelling * fish...

Many geometrical schemes - or map projections - are used to represent the curved surface of the Earth on map sheets. Canada uses the Universal Transverse Mercator (UTM) system. It is called transverse because the strips run north-south rather than east-west along the equator. This data class...

The dataset identifies the location and types of ANSIs that are commonly used in maps for resource management purposes. Official LIO title: ANSI [ANSIs]: Areas of Natural and Scientific Interest [ANSI]: Areas of Natural and Scientific Interest

A feature is a representation of a real world object, such as a lake, stream, dam or rapid. There are three hydrographic feature classes:  points, lines and polys.   All may impede or be hazardous to waterflow and/or navigation on a watercourse or waterbody. This data shows natural and manmade...

Hamlets are smaller settlement areas identified in municipal official plans, generally without municipal water and sewer servicing. For precise boundaries and locations of hamlets, the appropriate municipality should be consulted.

A single-tier municipality doesn't form part of an upper-tier municipality and assumes all municipal responsibilities set out under the Municipal Act and other Provincial legislation. A lower-tier municipality forms part of an upper-tier municipality. Municipal responsibilities set out under the...

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 *...

Get data on fire response plan area boundaries and recommended response types for wildfires. This dataset shows the boundaries of fire response plan areas and provides the recommended response type that corresponds to the official fire response plan for each area. Fire response types include: *...

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

A building is a structure that has a roof and walls and stands more or less permanently in one place. Small buildings have only their location recorded. A 'building to scale' is a structure that has one dimension larger than 50 metres for the 1: 20,000 scale and larger than 30 metres for the 1:...

This spatial dataset represents the locations of aquatic resource area (ARA) line segments derived from corresponding line features in the Ontario Hydro Network. ARA line segments may represent a portion of a water body or an entire water body (such as a lake, river or stream). Attributes for...

This layer is derived from data provided from Nav Canada. Where possible, it is spatially aligned with Ontario land parcel layers. Data is continually updated. This layer should not be used for navigation purposes. Official LIO title: Airport Official

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
