The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Trends in Canada's bird populations indicator reports population trends of Canada's native bird species from 1970 to...

In an effort to increase transparency and to facilitate access to information on substances in Canadian commerce, the Government of Canada is publishing a summary of the information received in response to the Notice with respect to perfluorohexane sulfonic acid, its salts and its precursors...

To increase transparency and to facilitate access to information on substances in Canadian commerce, the Government of Canada is publishing a compilation of the non-confidential information received in response to the Notice with respect to bisphenol A (BPA) and BPA structural analogues and...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Huron and St. Marys River nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is integrated into an overall...

National Water Monitoring Program for Pesticides (NWMPP) water quality data are presented for a network of freshwater sites across Canada. A two-year pilot program is being conducted in partnership between Health Canada (HC), Environment and Climate Change Canada (ECCC), and Agriculture and...

This study set out to provide an up-to-date portrait of the per- and polyfluoroalkyl substances (PFAS) contamination status in a freshwater food web from the St. Lawrence River (QC, Canada). Water, sediments, aquatic vegetation, invertebrates, and some fish species were targeted for analysis. All...

This study examined the effect of two dinonylnaphthalene sulfonic acids (NSAs) on freshwater organisms: calcium dinonylnaphthalene sulfonate (CaDNS), and dinonylnaphthalene disulfonic acid (DNDS). Chronic effects were characterized by exposing fertilized fathead minnow eggs to sediment-associated...

Increased flux of carbon and nutrients from human activities in river basins were linked to acidification and deepwater hypoxia in estuaries and coastal areas worldwide. Annual loads (1995–2011) of suspended particulate matter (SPM), dissolved organic carbon (DOC), total nitrogen (TN) and total...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Temperature change in Canada indicators show the yearly and seasonal surface air temperature departures for the years...

Communities in east Hudson Bay and James Bay are concerned about ecosystem changes observed in recent decades, particularly related to sea-ice conditions, and also about potential impacts of contaminants from long-range atmospheric transport and regional human activities. The Arctic Eider...

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...

Long-term freshwater quality monitoring data for sites in Newfoundland and Labrador (NL) for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Parks Canada. Environment and Climate Change...

Long-term freshwater quality monitoring data for over 12 sites in the Saint John and St. Croix River basins for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate...

Water quality and suspended sediment monitoring and surveillance data collected from the connecting channels of the Great Lakes to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment...

Sediment quality data from the Great Lakes collected to determine baseline status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment quality objectives and identify emerging issues are included in this dataset.

This dataset contains the concentrations of contaminants found in individual and pooled captured Yellow Perch (Perca flavescens) and Shorthead Redhorse (Moxostoma macrolepidotum) from 5 site locations (Stag Island, Lake Huron, Walpole Marsh, Chanel Ecarte, and Chenal Ecarte/Port Lambton) within...

Water quality and ecosystem health data collected in the Great Lakes and priority tributaries to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with water quality objectives and identify emerging...

This file is produced by the Transportation Division of Environment and Climate Change Canada (ECCC). It contains basic information summarizing notices of defect and other company notifications submitted to ECCC. The purpose of the file is to disseminate information pertaining to emission-related...

Atmospheric concentrations and deposition rates of particulate elements are important indicators for determining the potential impacts of the oil sands industries on the local environment. The datasets consist of measured ambient air concentrations (in PM2.5 and PM2.5-10) and estimated deposition...

Long-term freshwater quality monitoring data for over six sites in the Yukon River Basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC)...
