The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada’s performance on key environmental sustainability issues. The data collection contains datasets that track water quality within Canada. The Water quality in Canadian rivers indicators...

The Canadian Environmental Sustainability Indicators CESI program provides data and information to track Canada's performance on key environmental sustainability issues. The Air Pollutant Emissions indicators track the total emissions of key air pollutants from anthropogenic human-related...

The radar network consists of 31 weather radars spanning Canada's most populated regions, providing coverage to over 95% of the population. The network's primary purpose is the early detection of developing thunderstorms and high impact weather.

Surface freshwater quality monitoring in the Fraser River Basin is carried out under the Canada-British Columbia Water Quality Monitoring Agreement. Monitoring is conducted to assess water quality status and long-term trends, detect emerging issues, establish water quality guidelines and track...

The Ice Thickness Program Collection contains ice thickness and snow depth measurements for 195 sites. Sites such as Eureka and Resolute have ice thickness records that go as far back as 1947. Record length varies from station to station with some of the Arctic stations exceeding 50 years of...

Pollution Prevention (P2) Planning Notices published in the Canada Gazette under the Canadian Environmental Protection Act, 1999 (CEPA) legally require persons subject to the Notice to prepare and implement a pollution prevention plan in respect of a specified substance(s). Environment and...

This spatial file includes the polygon boundaries of the four Pacific Great Blue Heron Conservation Regions in British Columbia, as described in the management plan. These Conservation Regions are recognized based on degree of isolation, population sizes, and differences in trends and threats....

Fathead minnow (Pimephales promelas) embryos and larvae are frequently used in toxicology, including short-term embryo-only tests which often use small volumes of test solution. The effect that such conditions may have on Fathead minnow development has yet to be explicitly described. Here we...

Lake sediment cores were collected from several locations in Canada as part of the historic mercury and heavy metal deposition trend, analysis, and research component of the Clean Air Regulatory Agenda/Climate Change and Air Pollutant (CARA/CCAP) and Oil Sands Monitoring (OSM) programs. The...

Recent and historical deposition of mercury (Hg) are examined over a broad geographic area from southwestern Northwest Territories to Labrador and from the U.S. Northeast to northern Ellesmere Island using dated sediment cores from 50 lakes (18 in midlatitudes (41-50 degrees North), 14 subarctic...

The Canadian Environmental Sustainability Indicators CESI program provides data and information to track Canada's performance on key environmental sustainability issues. The Protected Areas indicators report the amount and proportion of Canada's land and freshwater and marine area that is...

The Canadian Meteorological Centre CMC produces Numerical Weather Prediction NWP as one of the key inputs to the Meteorological Service of Canada's overall public weather and environmental prediction and warning process. The raw data from NWP is made available to outside users who may use it...

The bioaccumulation of a broad range of pharmaceuticals and personal care product chemicals (PPCPs) was studied in Cootes Paradise Marsh (CPM), an urban wetland that receives tertiary treated municipal waste waters as well as urban storm runoff. PPCPs were measured in caged and wild goldfish, as...

This dataset contains a compilation of Migratory Bird Sanctuaries, National Wildlife Areas, Key Terrestrial Sites, Key Marine Sites, Important Bird Areas, RAMSAR Wetlands, and newly identified important areas for Birds within Nunavut.

The Special Studies presented on this site are special measurement campaigns (with durations of several weeks to several years) carried out by the Air Quality Research Division of Environment Canada and its government, university and industry collaborators. The Special Studies data sets consist...

Provides public access to archived sediment data daily loads, daily concentration, instantaneous concentration for stations of interest using search criteria. The sediment monitoring program discontinued in 1989. Archived sediment data are disseminated both online and offline via MS Access file.

Climate Data Products at Environment Canada comprise of four different datasets: Almanac Averages and Extremes, Monthly Climate Summaries, Canadian Climate Normals, and Canadian Historical Weather Radar. Almanac Averages and Extremes provides average and extreme temperature and precipitation...

These daily forecasts describe the ice edge using latitude and longitude coordinates and for each marine area, the total ice concentration, the predominant ice stage of development and the concentration of the oldest ice type. Warnings are issued as appropriate. The forecasts are valid from the...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Releases of Harmful Substances to the Environment indicators track anthropogenic releases to air and water of three toxic...

This file includes the spatial boundaries for the Pacific Great Blue Heron Potential Area of Occupancy for its entire Canadian range. The Potential Area of Occupancy is a simple model that highlights the heron's preferred forest habitat at a high level. Potential Area of Occupancy is defined as...
