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.

The Agricultural Resource Inventory 1983 (ARI 1983) dataset includes agricultural land use and drainage systems information. This dataset evaluates the mix of crops and classifies them into different categories which are valid over a long period of time. Mapping these systems provides an overview of the location, quantity and quality of the use of agricultural land in southern Ontario. Used by farmers, land use planners, municipal officials, policy makers and the general public. This dataset is no longer collected or maintained. Information and data held by the Ontario Ministry of Agriculture, Food and Agribusiness for this record is historical.

This data set shows utility points that provide services for: * power * water * communications * heating fuel They include: * fibre optic stations * hydro stations * lock pumping stations This product requires the use of geographic information system (GIS) software.

This dataset was created to provide land use information on the Oak Ridges Moraine and is the basis for Ontario Regulation 140/02. The data was digitized at 1:10,000 or better using 0.5 metre air photos, MNR, DMTI, Upper and Lower-tier Official Plans and digital vector layers.

The Ministry of Natural Resources defines ecological units on the basis of bedrock, climate (temperature, precipitation), physiography (soils, slope, aspect) and corresponding vegetation. This enhances their compatibility with national and continental classification systems. The ecological land classification (ELC) of Ontario is used for descriptive, planning, and resource management purposes. The upper levels in its hierarchy may be relevant for provincial and municipal land-use planning initiatives. The lower (finer-scale) levels of the hierarchy are most useful for detailed resource management prescriptions and other local and site planning applications. This packaged dataset is classified into 3 hierarchical categories: * Ecozone: used for national and coarse-scale provincial reporting such as analyses of climate, demographics and watersheds * Ecoregion: used for determining the significance or status of wetland classes and certain other natural heritage features (e.g., old growth forest), setting targets for Wilderness Class Provincial parks, State of the Forest reporting and studying natural disturbance regimes * Ecodistrict used for assessing biodiversity levels, defining seed zones, mapping ecosystem types and setting targets for the identification of natural heritage systems [Introduction to ecological land classification](https://www.ontario.ca/page/introduction- ecological-land-classification-systems)

This new data class brings over data from the Waste Management Information System (WMIS), which is a Microsoft Access based database used by the Ministry of Natural Resources (MNR) to track Waste Management Sites. This was married with the spatial data from Waste Disposal Sites where possible Different Waste Disposal Site types collected by the Ministry of Natural Resources include: * Compost Disposal * Hazardous Waste Disposal * Household Waste Disposal * Industrial Waste Disposal * Septic Drying Bed * Septic Field * Sewage Disposal * Tile Bed * Transfer Station This product requires the use of geographic information system (GIS) software.

Includes: * contour land * contour land approximate * contour land auxiliary/interpolated * contour land depression In southern Ontario the contour interval is 5 meters. In the near north the contour interval is 10 meters. In the Far North the contour interval depends on the information source. Data is collected on an irregular basis.

Rivers included in this map series include: * Albany * Winisk * Severn * Moose * Ekwana * Attawapiskat The maps display gauging systems such as cost share agreement gauges, Water Survey of Canada gauging stations and Meteorological Survey of Canada Climate stations. Dams, their jurisdictional owners and Far North First Nations communities are included.

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 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.
