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...

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)...

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.

Displays areas regulated as a conservation reserve in order to: * permanently protect representative ecosystems, biodiversity and significant elements of Ontario's natural and cultural heritage * provide opportunities for ecologically sustainable land uses, including traditional outdoor heritage...

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.

Data show where pathogens - fungal, bacillial or viral - have caused damage by reducing growth rates, tree vigor or have killed trees. Examples of forest diseases include White Pine Blister Rust, Armillaria Root Rot etc. The Government of Ontario tracks forest damage events to help proactively...

Crown Game Preserves were established to prohibit or regulate the hunting and trapping of wildlife in specific areas to restore local populations.

Examples include: * shoreline access * enhanced shoreline access (with a dock or pier) * boat launches This data was created to be used as part of the Fish ON-Line mapping application.

Elevation data is the representation of the height of the ground at a location on earth. This data allows users to discover the extent of elevation products, and the metadata associated with it.

This information is used  to manage oil and gas rights on offshore Crown lands in Ontario. A grid system of blocks and tracts is used to divide the area. 1 block =  5 minute longitude by 5 minute latitude numbered area. 1 tract =  1 minute longitude by 1 minute latitude area, assigned by letters...

This dataset represents the locations of licenced and permitted pits and quarries regulated by the Ministry of Natural Resources and Forestry under the Aggregate Resources Act, R.S.O. 1990. Aggregate site data has been divided into active and inactive sites. Active sites may be further subdivided...

The spatial accuracy of the lot fabric for some townships has been improved through the Ontario Parcel, Township Realignment and Township Improvement projects. Improvements to the fabric may include: * road allowance widths * spatial changes to better represent the location of lot boundaries *...

These signs serve a variety of purposes ranging from providing general information and safety warnings, to enforcement and land management notices to the general public. MNR signs are erected to support and enforce such provincial acts as the: * Fish and Wildlife Act * Public Lands Act...

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

Site Regions and Site Districts of Ontario represent an early Ecological Land Classification (ELC) system originally developed by Angus Hills. This dataset was revised by the ELC Working Group in 2000 to better reflect new information and new technology. The Site Regions of Ontario was used for...

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)....

Information about roads under MNRF jurisdiction may fall within the responsibility of several different ministry branches and including: * Forests Division * Parks, Lands & Waters Branch * Resource access roads The dataset also contains roads not under the jurisdiction of the MNRF like...

MNR regions were created to help manage ministry programs and resources at a regional level. Extents of the regions were originally compiled by description of: metes and bounds, topographic features, geographic township boundaries, territorial district boundaries, etc. MNR regions consist of a...

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...
