This study aimed to determine whether the pharmaceutical metformin had toxicological effects on the fathead minnow (Pimphales promelas) in their various life stages—from eggs to adulthood. Endpoints included survival, growth, and reproductive development. Fathead minnows were exposed to metformin...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The nutrients in the St. Lawrence River indicator reports on the status of total phosphorous and total nitrogen...

This study aimed to provide insights into how climate-driven diet shifts may impact contaminant exposures of Arctic species. We compared feeding ecology and contaminant concentrations in ringed seals (Pusa hispida) from two Canadian sub-Arctic (Nain and Arviat) and two Arctic sites (Sachs Harbour...

The Multi-Sector Air Pollutants Regulations set air pollution emission standards across Canada for several industrial sectors. They limit the amount of nitrogen oxides (NOx) emitted from gaseous fuel-fired non-utility boilers, heaters and stationary spark-ignition gaseous fuel-fired engines. They...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Status of key fish stocks indicator reports the status of key fish stocks. Federal scientists use a variety of scientific...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Harvest levels of key fish stocks indicator compares harvest rates with established harvest limits. These limits are...

This data set contains concentrations of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada. Scientific...

We publish Canada’s greenhouse gas (GHG) and air pollutant emissions projections each year. The GHG emissions projections help us measure progress in reducing greenhouse gas emissions and combating climate change. GHG emissions projections are presented for a few scenarios. The air pollutant...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Snow cover indicator shows how Canada's snow cover is changing from year-to-year and over time. Snow cover extent is...

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 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 emissions from human activities of 6 key air pollutants: sulphur oxides (SOX),...

Tire wear particles end up on roads where they may run off into nearby rivers and lakes by rain and snowmelt. This study examined how toxic these tire particles are to eggs and the newly hatched larvae of the fathead minnow (Pimephales promelas). Tire particles were finely ground up and were...

The Water Survey of Canada provided a digital archive of river ice thickness measurements at four hydrometric monitoring stations along the Liard River. The average ice thickness measurements were extracted and compiled to the attached .csv file. The stations include: Liard River at Upper...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Ability of the agricultural landscape to support wildlife indicator maps the relative value of Canada's agricultural...

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 emissions from human activities of 6 key air pollutants: sulphur oxides (SOX),...

Under the Clean Fuel Regulations (CFR), registered creators, foreign suppliers and carbon-intensity contributors can use the Fuel Life Cycle Assessment (LCA) Model to calculate a carbon intensity (CI) for the purposes of creating credits. In order to calculate those CIs, the following documents...

The Canadian Aquatic Biomonitoring Network (CABIN) is an aquatic biomonitoring program for assessing the health of fresh water ecosystems in Canada. Benthic macroinvertebrates are collected at a site location and their counts are used as an indicator of the health of that water body....

The Air Quality Health Index (AQHI) is a scale designed to help quantify the quality of the air in a certain region on a scale from 1 to 10. When the amount of air pollution is very high, the number is reported as 10+. It also includes a category that describes the health risk associated with the...

The Atlantic dataset is part of Environment and Climate Change Canada’s Shoreline Classification and Pre-Spill database. Shoreline classification data has been developed for use by the Environmental Emergencies Program of Environment and Climate Change Canada for environmental protection...

The Metal Mining Effluent Regulations came into force in 2002 pursuant to the Fisheries Act to regulate the deposit of mine effluent and mine waste into waters frequented by fish. The Metal Mining Effluent Regulations were amended in 2018, and are now known as the Metal and Diamond Mining...
