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.

Travel Information Centres are available throughout the province of Ontario, and offer tourists and travelers insight and information about Ontario. For more details about these centres, please visit [Info Centres](https://www.destinationontario.com/en-ca). Travel Information Centres can also be viewed on a map, by visiting [Ontario 511](https://511on.ca), and can be found under the "service" layer.

This dataset contains linear features constructed by beavers. The linear features are captured to scale on: * single line rivers * lakes * double line rivers We are no longer updating this data. It is best suited for historical research and analysis.

Pavement condition data is collected annually using an Automatic Road Analyzer (ARAN). Based on the automated data, the condition of the pavement is evaluated in terms of distresses (Distress Manifestation Index, DMI), wheel track rutting (in mm) and roughness (International Roughness Index, IRI). These indices are integrated into one Pavement Condition Index (PCI) for overall pavement condition reporting and analysis.

Interchanges are shown on the Official Road Map of Ontario (ORM) as information for the travelling public. This feature class includes all interchanges on provincial highways as well as interchanges on other roads (eg. Municipal, outside of Ontario and US) that are shown on the ORM. *[ORM]: Official Road Map *[eg.]: for example *[US]: United States

This dataset consists of man-made point features in a transportation network. Transport point features include: * Culvert Railway Symbolized - a enclosed drain under a railway * Culvert Roadway Symbolized - an enclosed drain under a roadway * Turntable Railway - a rotatable platform with a track, used to turn locomotives and cars We are no longer updating this data.

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 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
