MNR regions are divided into districts - smaller organizational units - to help manage ministry programs and resources. Extents of the districts were originally compiled by description of: metes and bounds, topographic features, geographic township boundaries, territorial district boundaries,...

Bait resources in most of the province are assigned to harvesters through the use of a block system -- 1 harvester per 'bait harvest' area. There are exceptions to the block system (e.g., Lake Erie), where bait is allocated to multiple users fishing the same area.

Ontario's Crown forest is divided into geographic planning areas, known as forest management units. Most of these units are managed by individual forest companies under a Sustainable Forest License. A forest management unit is identified by an assigned official name (e.g., Black Spruce Forest)...

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 data set shows utility lines that provide services for: * power * water * communications * heating fuel They include: * communication lines/submerged communication lines * hydro lines/submerged hydro lines * natural gas pipelines/submerged natural gas pipelines * water pipelines/submerged...

The Fish Pathogen Boundary Segment layer forms the boundary of the Fish Pathogen Management Zones and is made up of segments that were taken from the Ontario Road Network. This data class was created in order to store the road name information associated with each segment that makes up the fish...

This spatial data identifies breeding zones used by forest managers and forest genetic associations to manage provincial forest genetic assets. The data: * shows the boundaries of breeding zones * identifies the primary or target species within each zone Species are associated with certain...

Fish ON-Line is a mobile fishing tool with information on where to fish in Ontario. It includes information for over 20,000 waterbodies including: * fish species observations * fish stocking * fishing regulations and sanctuaries * fishing access points * lake depth contours * licence issuer...

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 Ontario Watershed Information Tool (OWIT) is used to calculate information about Ontario’s watersheds. Watersheds are areas of land where surface water converges to a single point. Water professionals in the public and private sectors and academia use OWIT to better understand water flow in...

This data is used for referencing spatial and tabular Forest Resource Processing Facility information. Each facility has one or more processing sites, each dedicated to processing resources for a specific purpose. For example, a pulp, paper and paperboard facility has one processing site to...

This spatial dataset represents the locations of aquatic resource area (ARA) survey points. ARA survey points 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...

The Ontario Dam Inventory (ODI) is an inventory of medium and large dams throughout Ontario. It uses a point-based system (x, y location) to identify each dam location. The ODI does not contain: * small dams * small water control structures * beaver dams * water crossings * road embankments *...

A building is a structure that has a roof and walls and stands more or less permanently in one place. Symbols are used when buildings and structures are permanent landmarks. Symbolized buildings have no side larger than 50 metres for 1:20,000 data or no side larger than 30 metres for 1:10,000...

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...

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 locations of wells that have been drilled for oil production, gas or salt resources or for underground storage of hydrocarbons. This data can be used for land use and resource management, emergency management, as well as compliance and enforcement in the petroleum industry. The Data is...

General information on the location of towns and villages (settlement areas) in the countryside areas protected by Greenbelt plan. For precise boundaries and locations of settlement areas, the appropriate municipality should be consulted.

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....

Data set contains geographical referencing information like: * type of feature or place * location coordinates * geographic township * municipal and map references Also contains places and background information behind their official naming like: * name status * naming date * name origin * naming...
