Rideau Canal Skateway - Ice condition by sectionEach winter, the NCC transforms the historic Rideau Canal into the world’s largest skating rink. The Rideau Canal Skateway winds its way through the heart of the National Capital over a total length of 7.8 km. A UNESCO World Heritage Site, the Rideau Canal in winter becomes a treasure that is the pride of the National Capital and a signature destination.The skating season typically runs from January to early March, but it is weather-dependent. When open, the Skateway is free and accessible 7 days a week, 24 hours a day.When the Skateway is open, ice conditions are monitored by section twice daily, at approximately 8 am and 4 pm.

Waterbody types include: * Lake * River * Canal * Reservoir * Kettle lake * Pond * Beaver Pond * Ocean This product requires the use of geographic information system (GIS) software.

The “Major Basins of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing polygon features representing the 23 major basins of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The Project is subdivided by ‘incremental gross drainage areas’ associated to individual hydrometric gauging stations. The maximum area that could contribute runoff to each gauging station, less that of its upstream neighbour(s) is called an ‘incremental gross drainage area’. Conceptually, the major basins are collections of the “incremental gross drainage areas” associated with particular major river or lake reach (for example, reaches of the Saskatchewan or Athabasca River). In practice, each major basin consists of the collection of incremental gross drainage areas, whose gauging stations’ numbers have collections of the same three first characters. For example, the Assiniboine River major basin contains the incremental gross drainage areas whose gauging station numbers start with 05J, 05M, or 05N.

Stream Centreline Network derived from 1:50,000 scale mapping. Each stream channel is represented by one or more line segments. Based on the 1:50,000 scale Canadian National Topographic Series of Maps.

The Major Projects Inventory (MPI), which is published quarterly, lists all major projects that are proposed, planned or underway in British Columbia. These are projects with a capital cost of at least $20 million each within the Lower Mainland and projects valued at $15 million or more in the rest of B.C. This is a point layer.

In August 2025 the Major Projects Office was launched, with the mandate to advance major projects in Canada and streamline federal regulatory project approval.This dataset was created to provide open access to key information about the projects and transformative strategies that have been referred to the Major Projects Office. This dataset can be layered with other data available on the Open Science and Data Platform. By accessing this data, users can conduct more comprehensive analyses to support evidence-based decision-making and inform regulatory processes including future impact assessments.Please visit the Major Projects Office for more information.

The “Major Drainage Systems of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing polygon features representing the three (3) major drainage system basins of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The Project area has been split according into which body of water it drains: the Arctic Ocean, Hudson Bay or Gulf of Mexico.

A Culvert is a pipe (less than 3m in diameter) or half-round flume used to transport or drain water under or away from the road and/or right of way. Culverts that are greater than or equal to 3m in diameter are stored in the MoT Bridge Structure Road Dataset. It is a Point feature
