The Magpie River ramping rate study (2000–2017) investigated the ecological effects of hydroelectric flow regulation on fish, invertebrates, and water quality in the Magpie and Batchawana rivers in the Algoma Region of Ontario. Conducted under a Fisheries and Oceans Canada–Brookfield Renewable partnership, the study employed a Before-After-Control-Impact (BACI) design to assess whether ramping rate restrictions at the Steephill Falls Waterpower Facility improved downstream conditions. Initial restrictions (2002–2005) were later removed, allowing unrestricted flow changes until 2017. In this dataset, monthly sampling from spring to fall included chlorophyll a and water chemistry at multiple sites to monitor productivity and detect irregularities. Analyses followed APHA standard methods, with chlorophyll a, pH, alkalinity, and conductivity processed at Fisheries and Oceans Canada, and major ions and nutrients at the Great Lakes Forestry Centre in Sault Ste. Marie, Ontario. Findings contribute to understanding flow management impacts on river ecosystems.

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.

This dataset shows MTO managed/maintained picnic park locations. It was created as part of the Digital Cartographic Reference Base (DCRB) for the production of Official Road Map of Ontario (ORM). Picnic parks are shown on the Official Road map of Ontario as information for the travelling public. *[MTO]: Ministry of Transportation

The Digital Elevation Model (DEM) data is organized into 20km x 20km tiles with a spatial resolution of 5m. This data is intended to be used for pre-engineering survey and design as well as the production of planimetric mapping at differing accuracies. This data is intended for GIS and remote sensing application that require a high resolution, high accuracy elevation model. Official GEO title: Greater Toronto Area digital elevation model 2002

This dataset contains manmade linear features in a transportation network, such as bridges and railway tunnels. It does not include roads. The linear features included are: * aerial cable ways * railway bridges * roadway bridges * railway and road bridges * pedestrian/cycle bridges * railway culverts * roadway culverts * parking lot limits * roads - edge * railway tunnels * roadway tunnels * road - under construction – edges We are no longer updating this data. It is best suited for historical research and analysis.

The Ministry of Transportation's Remote Northern Transportation Office in Thunder Bay operates 29 airports. These are located in Ontario's far north, extending from the Manitoba border on the west to Hudson's Bay on the north and to the Quebec border on the east. Except for Pickle Lake and Armstrong, these airports serve aboriginal communities, which have no all-weather road access to the rest of Ontario.
