This data represents the Ministry of Natural Resources (MNR) administrative boundaries from 1997-2022. Ministry of Natural Resources (MNR) administrative areas divide Ontario into smaller organizational units. These units were used to manage ministry programs and resources at a district and regional level. Regional and district boundaries were originally created based on: * metes and bounds * topographic features * geographic townships boundaries * territorial district boundaries We made changes to district boundaries over time. We are no longer updating this data. It is best suited for historical research and analysis. MNR regions MNR regions were created to help manage ministry programs and resources at a regional level. Regions consist of several districts. MNR districts MNR regions were divided into smaller organizational units called districts. MNR areas MNR districts were further divided into areas.

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

This data set is an index identifying Ontario Base Map (OBM) map tiles and digital vector data available for each tile. Eastern and Southern Ontario is covered at a scale of 1:10,000 and Northern Ontario is covered at a scale of 1:20,000.

Ontario Base Maps (OBM) are a series of maps created and updated by the Ontario Ministry of Natural Resources between 1977 and 2000. The MNR extracted the 33 layers from their NAD83 NRVIS dataset to create the NAD83 digital OBM sheets and vector data packages. The data provided may not be spatially defined upon download and may need to be defined using GIS (e.g. NAD 83 UTM Zone 18).

Zoom in on the map above and click your area of interest to determine which PDF(s) you require for download.These maps are available for the Far North Land Use Planning Area at 2 scales (1:100,000 and 1:250,000). The maps were created as a resource for community-based Land Use Planning in the Far North of Ontario.

The historic bathymetry maps were created using simple methods to determine lake depths and were meant for resource management purposes only.Bathymetry is the measurement of water depth in lakes. From the 1940s to the 1990s, the Ministry of Natural Resources and Forestry produced bathymetry maps for over 11,000 lakes across Ontario.The data can be used by the general public and GIS specialists for:climate change modellingfish monitoring and other ecological applicationshydrologic cycle modellingrecreational fishing mapswatershed-based water budgetingThe maps were created using simple methods to determine lake depths. They were meant for resource management purposes only. Little effort was made to identify shoals and other hazards when creating these bathymetric maps.Since this data was collected, many constructed and naturally occurring events could mean that the depth information is now inaccurate, so these maps should not be used for navigational purposes.In many cases, these maps still represent the only authoritative source of bathymetry data for lakes in Ontario.Technical informationThese maps are being converted to digital GIS line data which can be found in the Bathymetry Line data class.The Bathymetry Index data class identifies if GIS vector lines have been created and the location of mapped lakes.The historic paper maps have been scanned into digital files. We will add new digital files to this dataset if they become available.The digital files have been grouped and packaged by regions into 13 compressed (zipped) files for bulk download.Note: package 99 contains scanned maps where the location shown on the map could not be determined.Product PackagesHistoric Bathymetry Maps - Package 1 (ZIP)Historic Bathymetry Maps - Package 2 (ZIP)Historic Bathymetry Maps - Package 3 (ZIP)Historic Bathymetry Maps - Package 4 (ZIP)Historic Bathymetry Maps - Package 5 (ZIP)Historic Bathymetry Maps - Package 6 (ZIP)Historic Bathymetry Maps - Package 7 (ZIP)Historic Bathymetry Maps - Package 8 (ZIP)Historic Bathymetry Maps - Package 9 (ZIP)Historic Bathymetry Maps - Package 10 (ZIP)Historic Bathymetry Maps - Package 11 (ZIP)Historic Bathymetry Maps - Package 12 (ZIP)Historic Bathymetry Maps - Package 13 (ZIP)Historic Bathymetry Maps - Package 99 (ZIP)Additional DocumentationBathymetry User Guide (Word)Bathymetry Package Map (Word)Bathymetry Lookup Values (Excel)StatusCompleted: Production of the data has been completedMaintenance and Update FrequencyNot planned: There are no plans to update the dataContactOntario Ministry of Natural Resources - Geospatial Ontario,geospatial@ontario.ca

Contained within the 4th Edition (1974) of the Atlas of Canada is a set of three maps. The main map shows areas for which there are 1:50 000 scale National Topographic System (NTS) map sheet coverages up to October 1970. This map also denotes whether the NTS sheets were published maps or advanced prints. The second map shows areas for which there are 1:25 000 scale NTS map sheet coverages up to October 1970. The 1:25 000 scale NTS map sheets are all denoted as being published maps. The third map shows areas covered by the 1:1 000 000 International Map of the World (IMW). The IMW sheets are also denoted as being published maps or advance prints. A supplementary text providing additional information on topographic map coverage of Canada up to October 1970 accompanies this map set.

This data set contains digital copies of the Wildlife Management Unit maps from the Surveyor General's Office, that are referred to in regulation.

A Wildlife Management Unit Legal (WMU) is an administrative coverage that identifies a geographic area (i.e. numbered divisions of the Province of Ontario), which serves as a permanent land base for wildlife research and management. These units have been developed in Ontario based on the environmental requirements of principal wildlife species, ecosystems, and consideration of suitability of boundaries to traditional and future users, landowners, municipalities and other jurisdictions. Boundaries are generally described by rivers, lakes, roads, and other features easily recognized on the ground. A few exceptions occur where less visible criteria (for example, township/district boundaries) have been used in the absence of suitable physical features.

The Ontario Imagery Web Map Service (OIWMS) is an open data service available to everyone free of charge. It provides instant online access to the most recent, highest quality, province wide imagery. GEOspatial Ontario (GEO) makes this data available as an Open Geospatial Consortium (OGC) compliant web map service or as an ArcGIS map service. Imagery was compiled from many different acquisitions which are detailed in the Ontario Imagery Web Map Service Metadata Guide linked below. Instructions on how to use the service can also be found in the Imagery User Guide linked below.Note: This map displays the Ontario Imagery Web Map Service Source, a companion ArcGIS web map service to the Ontario Imagery Web Map Service. It provides an overlay that can be used to identify acquisition relevant information such as sensor source and acquisition date. OIWMS contains several hierarchical layers of imagery, with coarser less detailed imagery that draws at broad scales, such as a province wide zooms, and finer more detailed imagery that draws when zoomed in, such as city-wide zooms. The attributes associated with this data describes at what scales (based on a computer screen) the specific imagery datasets are visible.Available ProductsOntario Imagery OCG Web Map Service – public linkOntario Imagery ArcGIS Map Service – public linkOntario Imagery Web Map Service Source – public linkOntario Imagery ArcGIS Map Service – OPS internal linkOntario Imagery Web Map Service Source – OPS internal linkAdditional DocumentationOntario Imagery Web Map Service Metadata Guide (PDF)Imagery User Guide (Word)StatusCompleted: Production of the data has been completedMaintenance and Update FrequencyAnnually: Data is updated every yearContactOntario Ministry of Natural Resources, Geospatial Ontario, imagery@ontario.ca
