Location data for natural gas distributors’ service areas boundaries that can be used in geographic information systems (GIS) applications.

An upper-tier municipality is made up of 2 or more lower-tier municipalities. Municipal responsibilities set out under the Municipal Act and other Provincial legislation are split between the upper-tier and lower-tier municipalities. A lower-tier municipality forms part of an upper-tier municipality. Municipal responsibilities set out under the Municipal Act and other Provincial legislation are split between the upper-tier and lower-tier municipalities. 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. Territorial districts are geographic areas in northern Ontario. They are described in the Territorial Division Act, and are composed of municipalities, geographic townships and un-surveyed territory.

This dataset shows MTO managed/maintained picnic park locations. It was created as part of the Digital Cartographic Reference Base (DCRB) for the production of Official Road Map of Ontario (ORM). Picnic parks are shown on the Official Road map of Ontario as information for the travelling public. *[MTO]: Ministry of Transportation

Note: This data has been replaced by the [Ontario Watershed Boundaries (OWB)](https://geohub.lio.gov.on.ca/datasets/mnrf::ontario-watershed-boundaries-owb). We are no longer updating this data. It is best suited for historical research and analysis. A watershed, also known as a catchment basin, includes all land that is drained by a watercourse and its tributaries. Watersheds are split into four categories: * primary * secondary * tertiary * quaternary These divisions are based on the federal framework originally known as the Water Resources Index Inventory Filing System. Ontario has 3 primary watersheds: * Great Lakes – St. Lawrence * Southwestern Hudson Bay * Nelson River Secondary watersheds are subdivisions of primary watersheds in Ontario. Most secondary divisions are either large river systems or groupings of small coastal streams. Tertiary watersheds are subdivisions of secondary watersheds in Ontario. Quaternary watersheds are subdivisions of tertiary watersheds. There are more than 1000 quaternary watersheds in Ontario.

Built-Up Areas are man-made land cover features, ranging from small hamlets at rural cross roads to large cities. This product requires the use of geographic information system (GIS) software.

The dataset contains line features which define trails that are used for: * hiking * backpacking * biking * horseback riding * cross-country skiing * snowmobiling * access to campgrounds

This index identifies project areas on provincial highways where aerial photography and photogrammetric mapping has been collected.

Zones were created to manage the potential spread of fish pathogens. This product requires the use of geographic information system (GIS) software.

A Fire Disturbance Area represents the mapped exterior perimeter of a forest fire. Mapping is derived from a variety of sources, such as GPS points and digitized paper maps. Prior to 1998, only fires greater than 200 hectares were mapped. Since 1998, fires greater than 40 hectares have been mapped. If adequate mapping exists for fires less than 40 hectares in size, they will be included in this data class. The [Forest Fire Info Map](https://www.lioapplications.lrc.gov.on.ca/ForestFireInformationMap/index.html?viewer=FFIM.FFIM) shows active fires, current fire danger and restricted fire zones in place due to high fire danger.
