Environment and Climate Change Canada

Meteorological forecasts are datasets that are products of current observations and are used to predict climate conditions for a future time and given location.

Designated as a Species of Special Concern in 2008, the entire range and potential area of occupancy for the Great Blue Heron is defined as terrestrial areas within the Coastal Douglas Fir and Coastal Western Hemlock Biogeoclimatic zones that are less than 10 km from a potential foraging area...

Environment and Climate Change Canada (ECCC) has been monitoring levels of persistent organic pollutants and heavy metals in seabird eggs collected from the St. Lawrence River and Gulf of St. Lawrence, Canada, since the end of 1960s. Two sentinel species were selected to monitor aquatic ecosystem...

The dataset contains large ensembles of bias adjusted daily climate model outputs of minimum temperature, maximum temperature, precipitation, relative humidity, surface pressure, wind speed, incoming shortwave radiation, and incoming longwave radiation on a 0.5-degree grid over North America....

Water quality monitoring data collected in priority tributaries to provide nutrient concentration data to estimate nutrient loads to the waters of the Great Lakes. Data is collected to advance the science to understand and address the complex problem of recurrent toxic and nuisance algae in the...

An Area of Concern (AOC) is a location where environmental quality is degraded compared to other areas in the Great Lake Basin resulting in the impairment of beneficial uses. A total of 43 AOCs were identified as a result of Annex 2 of the Great Lakes Water Quality Agreement (GLWQA).The...

On-going monitoring of the total column ozone and spectral ultraviolet radiation (UV) in Canada is carried out by the Canadian Brewer Spectrophotometer Network (CBSN). The data are used for periodic assessment of the state of the ozone layer, satellite data validation, and in forecasting ECCC’s...

Expanded Geographic Area (M9, M10, M11a, M12, BI1, RI1, SL1, SL2, QU1 [2013] and M9, M10, M11a, M12, BI1, BU1, BU2, RI1, SL1, SL2, QU1, MC2 [2011-March 2018]) Water quality chemistry data for 17 sites in the lower Athabasca River (LAR), the Peace and Slave rivers, and their tributaries, including...

This database contains model output files that were used in the 2021 Arctic Monitoring and Assessment Programme (AMAP) Assessment Report on Short-lived Climate Forcers (SLCFs) and subsequent journal publications. The datasets are stored here:...

This first version of the dataset (CanHoPmlyV1) contains homogenized time series of monthly total precipitation for 425 long-term stations in Canada. As detailed in Wang et al. (2023), it is based on the quality-controlled version 2020 of the Adjusted Daily Rainfall and Snowfall (AdjDlyRS)...

Shallow groundwater and the interaction of these waters with surface water in the mineable area of the Athabasca oil sands region are being examined to assess the role and importance of groundwater in the regional river ecosystems. Groundwater quality chemistry data is available from 182 shallow...

The Turkey Lakes Watershed (TLW) Study was initiated in 1980 by Environment Canada, Natural Resources Canada and Fisheries and Oceans Canada to evaluate anthropogenic perturbation of Canadian Shield ecosystems. Originally, the Study focused on the aquatic and terrestrial effects of acid rain, but...

This data set contains concentrations of hexabromocyclododecane (HBCD) in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTP's) and Landfills across Canada. Supplemental Information...

In an effort to increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is publishing a summary of the information received in response to the Notice to provide information for the risk management of 1,4-benzenediamine,...

As indicated in the Notice with respect to certain quaternary ammonium compounds in Canadian commerce — Phase 1 (the Notice), and in accordance with section 49 of the Canadian Environmental Protection Act, 1999 (CEPA), the Government of Canada is providing a summary of the information received in...

In an effort to increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is publishing a summary of the information received in response to the Notice to provide information for the risk management of certain coal tars and their...

The d4PDF-WaveHs dataset represents the first single model initial-condition large ensemble (SMILE, 100-member) of historical significant ocean wave height (Hs) at a global scale. It was produced using an advanced statistical model with predictors derived from Japan's database for policy...

This dataset contains 21 statistics (including extreme indices) of wind and waves calculated from hourly reanalysis data of historical surface winds and ocean surface waves for the Davis Strait Baffin Bay waters for the period 1979-2018 (each statistic has an annual and 12 monthly values). These...

This data set contains concentrations of organophosphate flame retardants in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTP's) and Landfills across Canada. Supplemental Information...

Ambient concentrations of speciated mercury (Hg) have been measured at many locations across Canada. Mercury in the atmosphere is measured in three operationally-defined forms - gaseous elemental mercury (GEM), reactive gaseous mercury (RGM), and particulate-bound mercury (PBM). Under most...
