The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada’s performance on key environmental sustainability issues. The human health impacts related to pollution indicators data collection contains datasets that assess human exposure to environmental chemicals and the potential effects this exposure may have on health. This information is provided in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables, and downloadable reports.

The Canadian Ice Service maintains a collection of Daily ice charts, Regional ice charts and Iceberg charts. These charts are available in GIF format and E00 (Regional Charts only).

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 values for a particular station over its entire period of record. Monthly Climate Summaries contains values of various climatic parameters, including monthly averages and extremes of temperature, precipitation amounts, degree days, sunshine hours, days without precipitation, etc. Canadian Climate Normals are used to summarize or describe the average climatic conditions of a particular location. Data is available for stations with at least 15 years of data between the periods of 1961-1990, 1971-2000 and 1981-2010. Canadian Historical Weather Radar compirses of historical images from the radar network providing a national overview of where percipitation is occuring.

This application generates ice coverage bar graphs and data tables for the selected region and given dates.

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.

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

1. Provides public access to real-time instantatenous water level collected at over 1800 active locations in Canada. These data are collected under a national program jointly administered under federal-provincial and federal-territorial cost-sharing agreements; 2. Provides public access to archived daily water level for stations of interest using search criteria. These data include: daily and monthly mean, max and min of water levels. For some sites, annual peaks and extremes are also recorded. Archived water level data are disseminated online; 3. Provides public access to a MS Access database file containing archived daily water level that users can download to their desktop. These data include: daily and monthly mean, max and min of water level. For some sites, annual peaks and extremes are also recorded. MS Access file is updated quarterly; 4. Provides public access to water level statistics for stations of interest using search criteria.

This database contains detailed information on various sorbents (materials used to absorb chemicals) with a particular emphasis on the compunds abilities to absorb oil from tanker spills.

Azo dyes are synthetic compounds used as industrial colorants, and some are predicted to be inherently toxic, bioaccumulative, and/or persistent based upon their chemical composition. This study addressed data gaps in current research which included the need to evaluate the toxicity of hydrophobic azo dyes to benthic invertebrates. The toxicity of a solvent dye, Sudan Red G (SRG), and two disperse dyes, Disperse Yellow 7 (DY7) and Disperse Orange 13 (DO13), to Hexagenia spp. and Tubifex tubifex was assessed in spiked-sediment exposures. The dye compounds appeared to degrade readily in the equilibrium and exposure periods, suggesting a limited persistence of the parent compounds in the environment under test conditions.Although azo dye degradation products could not be reliably quantified, one was detected in DY7 sediment samples that elicited toxic effects to Hexagenia and Tubifex, providing evidence that DY7 degrades. Hexagenia survival and growth endpoints responded with similar sensitivity to the dyes, but DY7 was the most toxic, with a 21-day IC25 (concentration associated with 25% inhibition) for growth of 9.6 μg/g. Comparatively, Tubifex reproduction was the most sensitive endpoint for all dyes with 28-day IC25s for young production ranging from 1.3 to 11.8 μg/g. At sublethal concentrations, toxic effects to Tubifex differed between dyes: the solvent dye exerted an effect primarily on gametogenesis (cocoon production), while disperse dyes, most notably DY7, caused effects on embryogenesis(development of worm inside the cocoon). This study indicated that there could be potential hazard to oligochaetes based on the observed effect concentrations, but given the lack of environmental measurements, the risk of these compounds is unknown. Further research is required to determine if degradation products were formed in all dye samples and whether toxicity was caused by the parent molecules, which have limited persistence under test conditions, or by their degradation products. To avoid underestimating toxicity, this study stresses the need to use an infaunal deposit feeder such as the oligochaete Tubifex in sediment toxicity assessments where highly hydrophobic compounds are present.

The Great Lakes Coastal Wetland Monitoring Program involves the monitoring of Great Lakes coastal wetland biota (fish, birds, anurans, aquatic macroinvertebrates) and habitat (vegetation, water quality) to provide information on coastal wetland condition for use in conservation and management decision-making. The main outputs from this program are a thorough assessment of the condition of over 1000 Great Lakes coastal wetlands and the implementation of a standardized long-term monitoring program for coastal wetlands across the Great Lakes basin. This program is funded under the Great Lakes Restoration Initiative (GLRI) by the United States Environmental Protection Agency (USEPA) and Great Lakes National Program Office. The Canadian Wildlife Service (CWS) of Environment and Climate Change Canada (ECCC) has been involved in the program since 2011, and over that time has conducted fish, vegetation, aquatic macroinvertebrates and water quality surveys primarily on the Canadian shore of Lake Ontario. Program data are available by request at: https://www.greatlakeswetlands.org/.
