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

A source protection area (SPA) is an area of land and water governed by a Source Protection Authority, an agency, person or body. This dataset defines the geographic boundaries where each SPA's terms of reference, assessment reports and source protection plans must be developed. *[SPA]: source protection area

## GIS data containing the boundaries of Provincially Significant Employment Zones in the Greater Golden Horseshoe as identified by the Minister of Municipal Affairs and Housing As areas of high economic output, provincially significant employment zones are strategically located to provide stable, reliable employment across the Greater Golden Horseshoe region. They provide opportunities to improve coordination between land use planning, economic development, and infrastructure investments to support investment and job creation over the longer-term.

Often these parcels were surveyed before township surveys in their area. They may also be supplemental to them (as is the case with some Cadastral Islands). Sometimes these were laid out after a township survey was done, so some may be part of a geographic township. Cadastral Location includes the following: GTP Block - Timber block used by the Grand Trunk Pacific Railway for feeding steam engines, building bridges, and for supplying railway ties. Mining Location - A parcel of land whose surveyed boundaries were laid out during the late nineteenth century for the Crown sale of land for mining purposes to groups or individuals. Cadastral Island - Island delineated on survey plans. It may or may not be part of a geographic township. Other Location - A parcel of land whose surveyed boundaries were laid out during the late nineteenth century for the Crown sale of land for various agricultural or farming purposes to groups or individuals. These locations are mainly found in Northern Ontario and also exist in the un-surveyed territories.

Hazardous forest types for wildland fire means forest types assessed as being associated with the risk of high to extreme wildland fire. This data is intended to help inform where further assessment is required and is to be used in conjunction with guidance from the Ministry of Natural Resources and Forestry .

The purpose of this dataset is to depict the boundaries of the Niagara Escarpment Plan. The outer boundary of the area covered by the Niagara Escarpment Plan is fixed and inflexible. It can only be changed by a plan amendment. It is formed by a combination of features like: * roads * railways * electrical transmission lines * municipal and property boundaries * lot lines * rivers * other topographic features [More information](http://www.escarpment.org)

MNR regions are divided into districts - smaller organizational units - to help manage ministry programs and resources. Extents of the districts were originally compiled by description of: metes and bounds, topographic features, geographic township boundaries, territorial district boundaries, etc. Changes to the extent of the districts have been made over time by MNR district offices. This product requires the use of GIS software. *[MNR]: Ministry of Natural Resources *[GIS]: geographic information system

Data has been collected primarily using a depth measurement device, such as an echo-sounder, in combination with a GPS for horizontal positioning. Other survey methods, such as bathymetric LiDAR may also have been used. The survey method used in each body of water is shown in the [Bathymetry Index](https://geohub.lio.gov.on.ca/datasets/mnrf::bathymetry-index ). *[GPS]: Global Positioning System

The Fish Pathogen Boundary Segment layer forms the boundary of the Fish Pathogen Management Zones and is made up of segments that were taken from the Ontario Road Network. This data class was created in order to store the road name information associated with each segment that makes up the fish pathogen management zone boundary. This product requires the use of GIS software. *[GIS]: geographic information system
