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.

Towers -- structures or buildings that are typically higher than their diameter and high relative to their surroundings -- are shown in this data set. They include: * communication towers * fire towers * microwave towers * radio towers * navigation beacons * lighthouses * lightning locators * meteorological towers

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 descriptive, planning, and resource management purposes. This upper level in its hierarchy was most useful for provincial and regional roll-ups of data and for strategic planning. Site Districts of Ontario is a more detailed lower (finer-scale) level of the hierarchy, and was more useful for detailed resource management prescriptions and other local and site planning applications. This layer is designed to be used as a spatial selection tool and as a background layer suitable for overlay and or intersection with numerous scales or current hydrologic data.

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) and a unique numeric code. Before any forestry activities can take place in a management unit, there must be an approved forest management plan in place for each management unit. Instructions for downloading this dataset: This product requires the use of geographic information system (GIS) software.

Data with the following information for large landfills: * landfill capacity * fill rates * estimated remaining capacity * engineering designs * reporting and monitoring details **This dataset was last updated in 2014 and contains out of date information. It has been replaced by the [Ontario landfills](https://data.ontario.ca/dataset/ontario-landfills) dataset.**

The Ontario in-filled climate data collection includes information from 339 monitoring stations maintained by the Meteorological Service of Canada. Historical climate data commonly has missing hourly and daily records due to equipment malfunctions, temporary site maintenance or other reasons. “In-filling” is a technical process that draws on data from nearby stations to fill in these missing records. This collection contains fully in-filled precipitation and temperature records for Ontario from 1950 to 2005. It is organized into eight separate databases in Microsoft Access format. One of the databases contains daily in-filled climate records. The remaining seven databases contain hourly in-filled climate records divided into regions for manageability.

Depicts the internal boundaries of the Niagara Escarpment Plan area. The 7 land use designations are: * escarpment natural area * escarpment protection area * escarpment rural area * [minor urban centre](/dataset/minor-urban-centres-in-the-niagara-escarpment-plan) * urban area * escarpment recreation area * mineral resource extraction area The land use designations represent the internal boundaries between designations within the Niagara Escarpment Plan. These internal boundaries are not intended to be site-specific and should not be used for accurate measurements. The exact delineation of designation boundaries on specific sites will be done by the implementing body through the application of the designation criteria as outlined in Part 1 of the Niagara Escarpment Plan, utilizing the most detailed or up-to-date information available and site inspection.

The spatial record for all the province's geographic areas affected by provincial level, area-specific land use policy. This layer may contain geometry from the: * provincial parks-regulated layer * conservation reserves-regulated layer * natural heritage values area layer *  wilderness areas layer * crown land MNR acquisitions layer * crown land MNR unpatented layer * CLUPA geometry (enhanced management areas and general use areas) layer Not to be used as a source of protected areas (provincial park, conservation reserve, etc.), crown land or private land boundaries. Official GEO title: CLUPA Provincial

The Provincial Digital Elevation Model (PDEM) is a general purpose dataset designed to represent true ground elevation and is based on best-available data across the province. This dataset has not been conditioned for any specific application.

This dataset is often used by users without access to the Provincial Forest Resource Inventory data, which contains information like municipalities and non-profit groups not affiliated with monitoring or maintaining the Forest Resource Inventory.
