Dataset contains laboratory-studied Fathead minnow (Pimephales promelas) survival when exposed to bitumen sediments from the oil sands region of northern Alberta, cut through the McMurray Formation (MF). These are the results of the toxicological exposures, when Fathead minnow embryos were exposed to water from simulated rainfall on the river sediments.

This collection of data summarizes the companies and facilities reporting under the Fuels Information Regulations, No. 1. This dataset includes total fuel volumes, sulphur contents and masses, and companies reporting production and/or importation of liquid fuels originating from crude oils, coal or bituminous sand. The information was provided to Environment and Climate Change Canada under the Canadian Environmental Protection Act, 1999.

The Stanley Park Winter Waterbird Survey, 1995-2019, was made possible through a co-operative effort between Environment and Climate Change Canada, the British Columbia Institute of Technology’s Wildlife and Recreation Program, and the Stanley Park Ecology Society. The intent of the survey is to collect data to estimate the presence, abundance, and distribution of waterbirds along the Stanley Park foreshore in Vancouver, British Columbia, Canada. This dataset is a compilation of species-level occurrence, abundance and distribution data of marine birds collected systematically for the last 23 years (1995-2019) on roughly a weekly basis between September and April each year along the Stanley Park seawall. This long-term dataset of marine birds, has a high value for analysing spatiotemporal trends in marine bird species.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. Canada's conserved areas indicators report the amount and proportion of Canada's terrestrial (land and freshwater) and marine area that is recognized as conserved. Well-managed conserved areas are one way to protect wild species and their habitats for present and future generations. Habitat conservation is a measure of human response to the loss of biodiversity and natural habitat. As the area conserved in Canada increases, more lands and waters are withdrawn from direct human development stresses, thereby contributing to biodiversity conservation and improving the health of ecosystems. In turn, healthy ecosystems provide benefits such as clean water, mitigation of climate change, pollination and improved human health. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for the data sources and details on how the data were collected and how the indicator was calculated.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Municipal wastewater treatment indicator measures the level of wastewater treatment provided to the Canadian population. Higher levels of wastewater treatment reduce the risk of pollutants from raw wastewater reaching the environment, where they pose risks to human and environmental health. This indicator is not a measure of municipalities' compliance with municipal, provincial or federal wastewater regulations or treatment standards. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for data sources and details on how those data were collected and how the indicator was calculated.

The Wastewater Systems Effluent Regulations (WSER), developed under the Fisheries Act, came into force in 2012 to manage wastewater releases by systems that collect an average daily influent volume of 100 cubic metres or more. The WSER also does not apply to any wastewater system located in the Northwest Territories, Nunavut and north of the 54th parallel in the provinces of Quebec and Newfoundland and Labrador. The WSER set national baseline effluent quality standards that are achievable through secondary wastewater treatment. The province of Quebec provided some combined sewer overflow data for 2020, which includes information on whether a discharge occurred at a combined sewer overflow point during the year. The map below shows the number of CSO points with at least one overflow event within each wastewater system. The map is available in both ESRI REST (to use with ARC GIS) and WMS (open source) formats. For more information about the individual reporting wastewater systems, datasets are available in either CSV or XLS formats. More information on the wastewater sector including the regulations, agreements, contacts and resource documents is available at: https://www.canada.ca/wastewater

Predicted and actual counts of sandpipers utilizing the portion of Roberts Bank along “Brunswick dike” (the shoreline between the base of the Roberts Bank Coal Port causeway northwestwards to Brunswick Point at the mouth of Canoe Pass).

Black carbon is a short-lived, small aerosol (or airborne) particle linked to both climate warming and adverse health effects. It is emitted from incomplete combustion of carbon-based fuels (i.e., fossil fuels, biofuels, wood) in the form of very fine particulate matter. Black carbon is not emitted on its own, but as a component of particulate matter less than or equal to 2.5 micrometres in diameter (PM2.5). As a member of the Arctic Council, Canada has committed to producing an annual inventory of black carbon emissions. This data will serve to inform Canadians about black carbon emissions and provide valuable information for the development of air quality management strategies. The data used to compile the report originate from sections of the Air Pollutant Emission Inventory (APEI) specifically fine particulate matter (PM2.5) emissions from combustion-related sources.

Wild fish community data (species, abundance, diversity, length, weight) for 2013 and 2019 are now available for tributaries of the Athabasca River (rivers Steepbank, Ells, Firebag, High Hills, Dunkirk, Horse, Muskeg, Tar and Calumet) and 2017 data for rivers and creeks adjacent to Christina Lake (Christina River, Sunday Creek, Birch Creek, Sawbones Creek, Jackfish Creek and Unnamed Creek). The composition and diversity of the fish communities in these waterbodies have been evaluated over time to identify changes in the presence and abundance of fish species in these waterbodies adjacent to SAGD oil sands mining activity and at sites that are outside of the Athabasca Oil Sands deposit and not influenced by mining activities. Not all waterbodies are adjacent to mining activities and these provide some information as to the natural variability and stability of these fish communities over time. This involved establishing baseline conditions in fish communities in the fall of 2013, 2017 and 2019. This baseline data has assisted in tracking changes in fish communities of these waterbodies over time. Fish community assessments (non-lethal sampling) were carried out in a reach of river using a Smith-Root 12B backpack, Smith-Root LR-24 backpack and or seine at the sites identified in Section 2.3. Length, weight, species identification, and external assessment were performed on fish collected. Fish were then returned to the water at the site of capture. This fish community assessment work commenced September 17th to 27th, 2013, October 3rd to 8th, 2017 and September 24th to October 2nd, 2019. This monitoring activity compliments and supports the Wild Fish Health program.
