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.

Prior to January 1, 2008, fishing divisions were administrative units to manage, monitor, assess and regulate recreational fisheries. Each zone was based on angler usage and ecological/geographic patterns. Refer to [Fisheries Management Zone for boundaries after 2008](/dataset/fisheries-management-zone).

This polygon data set contains the geographic boundaries of where meat inspection occurs across Southern Ontario.

Get data on fish stocking records from 1900 - 2012. This dataset is the most complete collection of historical fish stocking records available for the time period 1900 to 2012. 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)

Identifies First Nation Reserve boundaries defined by the Legal Surveys Division of Natural Resources Canada.

This dataset provides various Ministry of Natural Resources and Forestry business areas with fundamental forest inventory information needed to meet their program mandates.

A borehole is a general term for any narrow shaft drilled in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including: * extraction of water or fluid (e.g., oil) or gases (e.g., natural gas or methane) * for a geotechnical investigation * for an environmental site assessment * for mineral exploration * as a pilot hole for installing piers or underground utilities This data contains a continuous log of strata for each borehole as well as for geocolumns. A geocolumn is a collection of information from an examination of exposed substrate, such as in a quarry wall or along a roadway passage.

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 temperature and depth * fish species The ARA data classes are the authoritative source for generic spatial data related to fish species in Ontario. The data can be used for: * forest and fisheries management planning * municipal planning * natural heritage and land use planning * issuing work permits under the [Public Lands Act](https://www.ontario.ca/laws/statute/90p43), 1990 * issuing licences under the [Fish and Wildlife Conservation Act](https://www.ontario.ca/laws/statute/97f41), 1997 * fulfilling public information requests There are additional sensitive data related to provincially tracked species and species at risk that are not available as part of this open data package. Distribution of sensitive species data is approved on a need-to-know basis. Requests should be sent to [geospatial@ontario.ca](mailto:geospatial@ontario.ca).

This dataset provides a listing and relevant details for forest resource processing facilities (mills) that are licensed and operating or require a licence to operate in Ontario. Contents include: * Facility Code * Name * Facility Type * MNRF Region * Address * City * Province * Postal Code * Latitudinal and Longitudinal Coordinates All facilities that use 1,000 cubic metres or more of forest resources in one year require a facility licence.

Data with the following information for small landfills: * open/closed status * site owner * site location * Certificate of Approval number **This dataset was last updated in 2014 and contains out of date information. It has been replaced by the [Ontario landfills](https://data.ontario.ca/dataset/ontario-landfills) dataset.**
