Environment and Climate Change Canada

With the changing climate conditions, marine traffic along Canada’s coastal regions has increased over the past couple of decades and the need to improve our state of preparedness for oil-spill-related emergencies is critical. Baseline coastal information, such as shoreline form, substrate, and...

The purpose of the Long-Range Forecast Transient Intercomparison Project (LRFTIP) is to provide an archive of hindcast climatologies, describing the systematic behavior of models evolving from observation-based initial states, that can inform investigations into the transient behavior of...

In the oil sands air monitoring component, nitrogen dioxide (NO2) and sulphur dioxide (SO2) levels are monitored by ground-based instruments, satellites and other measurements. Monitoring of air pollutants from satellites is becoming an alternative to surface and aircraft measurements, and allows...

Information received in response to the 2017 Inventory Update (chemicals and polymers) To increase transparency and to facilitate access to information on manufactured and/or imported substances in Canada, the Government of Canada is providing a summary of the information received in response to...

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...

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...

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...

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...

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 dataset contains 21 statistics of wind and waves calculated from hourly reanalysis data of historical surface winds and ocean surface waves for the Canadian East Coast for the period 1954-2018 (each statistic has an annual, 4 seasonal, and 12 monthly values). These data can be used for...

Tributary Biomonitoring (Lower Athabasca River) Benthic macroinvertebrates, comprising insects, crusteaceans, molluscs and worms, represent a group of organisms used widely in environmental monitoring programs as early warning indicators to assess the effects of change in water quality...

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 water indicators track facility-based releases to water of 3 substances that are...

The Fish Contaminants Monitoring Program (FCMP) was initiated in 1976. The objective is to collect a variety of biological samples in freshwater environments for the purpose of determining ecosystem contaminant levels. Environment and Climate Change Canada (ECCC) collects biological samples from...

NETCARE is a network comprised of researchers from ten Canadian universities (University of Toronto, University of British Columbia, Université du Québec à Montréal, University of Waterloo, Université du Québec à Rimouski, Laval University, Dalhousie University, University of Calgary, Université...

Permafrost loss is pervasive across northern circumpolar regions. The loss of frozen ground has profound impacts on water resources at varying spatial and temporal scales via changes to predominant hydrological processes, runoff pathways and entrainment rates of solutes and sediments. Consensus...

Monitoring of sea ice dynamics is of vital importance to our overall understanding of how the Arctic cryosphere is responding to changes in the Earth's climate. With the recent launch of the RADARSAT Constellation Mission (RCM) in 2019 and the continuing operation of the Sentinel-1 (S1) fleet,...

Drought projections on seasonal to annual time scales are presented for Canada over the twenty-first century, based on the Standardized Precipitation Evapotranspiration Index (SPEI). Results make use of bias-corrected temperature and precipitation projections from 29 global climate models...

The Environmental Damages Fund (EDF), created by the Government of Canada in 1995, follows the Polluter Pays Principle to ensure that those who cause damage to the environment take responsibility for their actions. Prosecutors and judges can recommend that financial penalties (fines, awards...
