The Canadian Nuclear Safety Commission (CNSC) is publishing a database with environmental monitoring results collected as part of the Eastern Athabasca Regional Monitoring Program. The samples are collected near communities located in northern Saskatchewan.

The Aquatic Invasive Species Surveillance Database is a compilation of fish community and habitat data from DFO’s Aquatic Invasive Species and Invasive Carp Program early detection surveillance efforts in Canadian waters of the Great Lakes basin. Data includes: sampling site location, date, fish species and counts, and associated habitat information. Annual project-specific details including purpose/objectives and study methodology are often reported in the DFO Canadian manuscript report of fisheries and aquatic sciences series.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Air quality indicators track ambient concentrations of fine particulate matter, ground-level ozone, sulphur dioxide, nitrogen dioxide and volatile organic compounds at the national, regional and urban area levels and at local monitoring stations. 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.Canadian Environmental Sustainability Indicators: https://www.canada.ca/environmental-indicators

In permafrost dominated regions, a gap persists in our understanding of water resources, the influence of groundwater, and the impact of climate change at the regional scale. Regional scale modelling can help to advance the understanding of these impacts by integrating with regional climate models. For regional modelling to be tenable, ongoing development of modelling methods and conceptualizations is required. By developing a fully integrated numerical groundwater-surface water climate model using HydroGeoSphere (HGS) (Aquanty 2021) for a gauged basin within the discontinuous permafrost zone, this dataset allows the verification of existing numerical methods and the testing of various conceptualizations of integrated groundwater-surface water flow in permafrost regions at the regional scale. This work informs future modelling and forecasting of regional water resources in permafrost regimes.

The Regional Deterministic Air Quality Analysis (RDAQA) is an objective analysis of surface pollutants which combines numerical forecasts from the Regional Air Quality Deterministic Prediction System (RAQDPS) and hourly observational data from monitoring surface networks over North America in order to produce a better description of the air quality at every hour. Chemical constituents include 03, SO2, and NO2 gases, as well as fine particulate matter PM2.5 (2.5 micrometers in diameter or less) and coarse particulate matter PM10 (10 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available only for the surface level, at a horizontal resolution of 10 km. The products are presented as historical, annual or monthly, averages which highlight long-term trends in cumulative effects on the environment.

This geospatial data depicts preliminary offshore wind licencing areas recommended by the Committee for the Regional Assessment of Offshore Wind Development in Newfoundland and Labrador (Committee). These areas were identified as an interim product during the Regional Assessment process. The Committee is tasked to complete its Regional Assessment Report by January 2025. As part of the terms of amended agreement set out by the Governments of Canada and Newfoundland and Labrador, the Committee submitted an interim report to Ministers on March 22, 2024. This report included a preliminary map of recommended areas for offshore wind. Based on work completed to date, the Committee has found these areas are where offshore wind development is most likely feasible and will have the least impact within offshore Newfoundland and Labrador. These areas are preliminary and will be refined throughout the remainder of the Regional Assessment. Through the Regional Assessment process, the Committee is providing federal and provincial Ministers with information, knowledge, and analysis regarding future offshore wind development. Their work is intended to inform and improve future planning, licencing, and impact assessment processes. Any offshore wind areas identified by the Committee do not reflect official offshore wind licencing areas. The Committee is providing these areas to Ministers for their consideration, as the offshore wind regulatory process is being established.

Depicts priority area for work under the Regional Assessment of Offshore Wind Development in Newfoundland and Labrador. The Committee for the Regional Assessment of Offshore Wind Development in Newfoundland and Labrador (Committee) is responsible for providing information, knowledge and analysis regarding future offshore wind development (OSW) to inform and improve future planning, licencing and impact assessment processes. The Committee’s mandate is set out in the Agreement to Conduct the Regional Assessment of Offshore Wind Development in Newfoundland and Labrador (Agreement), and includes assessing potential environmental, health, social and economic effects of future OSW. The Agreement includes a broad Study Area. In November 2023, the Committee determined OSW interest in the foreseeable future is more likely within a portion of the Study Area set out in the Agreement. The Committee defined this portion of the Study Area as the assessment's Focus Area. The Committee continues to conduct the Regional Assessment (i.e., present information on existing conditions and consider potential impacts of OSW) within the Focus Area. The Committee's decision to define the Focus Area and supporting rationale is available here: https://iaac-aeic.gc.ca/050/evaluations/document/153431 The Agreement to conduct the Regional Assessment is available here: https://iaac-aeic.gc.ca/050/documents/p84343/147037E.pdf

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Air quality indicators track ambient concentrations of fine particulate matter, ground-level ozone, sulphur dioxide, nitrogen dioxide, and volatile organic compounds at the national, regional and urban levels and at local monitoring stations. The national and regional indicators are presented with their corresponding Canadian Ambient Air Quality Standard when available. Canadians are exposed to air pollutants on a daily basis, and this exposure can cause adverse health and environmental effects. 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.
