Get mapping data related to the Northwest Greater Toronto Area Transmission Corridor Identification Study. In June 2019, the Ministry of Energy, Northern Development and Mines along with Ontario’s electricity system planner, the Independent Electricity System Operator, launched the Northwest GTA Transmission Corridor Identification Study to identify an appropriate corridor of land for use by future power lines if and when the need arises.

This data breaks down estimated hunters as well as antlered, antlerless and total harvest numbers by: * wildlife management unit (WMU) * calendar year Harvest and active hunter numbers are estimates based on replies received from a sample of resident hunters and are therefore subject to statistical error. Additional technical and statistical notes can be found in the data dictionary.

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.

It includes: * data source * species * rearing location * developmental stage * stock strain * spawning year * stocking date Related datasets: * [Ontario waterbody location identifer](https://data.ontario.ca/dataset/ontario-waterbody-location-identifier)

The dataset has been used for the Great Lakes Conservation Blueprint Project for Aquatic Biodiversity. It can be used for: * research and aquatic species inventories * environmental impact and monitoring * watershed based resource planning and management * fisheries and other aquatic analysis Official GEO title: Aquatic Ecosystems Classification: Great Lakes Basin - Coast, Streams, Lakes and Wetlands

Historical Oil Fields are subsurface accumulations or 'pools' of crude oil designated as such for the purposes of the Oil, Gas and Salt Resources Act. This product requires the use of geographic information system (GIS) software.

This dataset contains a list of soil erosion control contractors in Ontario who offer design and construction services to landowners to help control soil erosion on agricultural land. The list is maintained by the Ministry of Agriculture, Food and Agribusiness (OMAFA) and includes contact names, business names, addresses and telephone numbers. The list is updated annually in April. These contractors hold a valid Certificate of Achievement from OMAFA. Holders of the Soil Erosion Control Contractors Certificate of Achievement have attended formal training developed and delivered by OMAFA and have passed an examination that tests their skill and knowledge in the area of design and installation of select soil erosion control structures such as grassed waterways, water and sediment control basins (WASCoBs) and rock chutes. More information can be found at [Soil erosion control contractors certificate holders](https://www.ontario.ca/page/soil-erosion-control-contractors-certificate-holders).

Flood tactical maps have currently been developed for the English River, Rainy River, Montreal River, Black River, Trent River, Madawaska, Magnetawan, Muskoka, Mississippi Valley, French, Sturgeon and Nippissing watersheds. The purpose of these maps is to show more succinctly the physiography of the region, the individual river watersheds, ongoing monitoring, location of dams, high risk dams/reservoirs and communities. We are no longer updating this data. It is best suited for historical research and analysis.

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 collected on an on-going basis and maintained in the Ontario Petroleum Data System (OPDS).

Southern Ontario Land Resource Information System (SOLRIS) is based on Ministry of Natural Resources' Ecological Land Classification (ELC) for southern Ontario (Lee et al, 1998). It is a land use inventory that supports a number of key Provincial initiatives including Source Water Protection, Natural Spaces, Biodiversity Conservation and State of Resources Reporting. The data covers the date ranges from 1999-2002 and 2009-2011.
