    The Greenhouse Gas Reporting Program (GHGRP) collects information on greenhouse gas (GHG) emissions annually from facilities across Canada. It is a mandatory program for those who meet the requirements. Facilities that emit 10 kilotonnes or more of GHGs, in carbon dioxide (CO2) equivalent (eq.) units, per year must report their emissions to Environment and Climate Change Canada. Emissions data are available by gas (in tonnes and tonnes of CO2 eq.) for each facility and each year of data collected (2004-Present). The GHGs included are: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulphur hexafluoride (SF6).

    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.

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

    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.

    1. Provides public access to real-time instantatenous streamflow 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 streamflow for stations of interest using search criteria. These data include: daily and monthly mean, max and min of flow. For some sites, annual peaks and extremes are also recorded. Archived streamflow data are disseminated online; 3. Provides public access to a MS Access database file containing archived daily streamflow that users can download to their desktop. These data include: daily and monthly mean, max and min of flow. For some sites, annual peaks and extremes are also recorded. MS Access file is updated quarterly; 4. Provides public access to streamflow statistics for stations of interest using search criteria.

    An Area of Concern (AOC) is a location where environmental quality is degraded compared to other areas in the Great Lake Basin resulting in the impairment of beneficial uses. A total of 43 AOCs were identified as a result of Annex 2 of the Great Lakes Water Quality Agreement (GLWQA).The Canada-United States GLWQA identifies 14 beneficial uses that must be restored in order to remove the designation as an Area of Concern. A beneficial use is defined as the ability of living organisms (including humans) to use the Great Lakes Basin Ecosystem without adverse consequences. A Beneficial Use Impairment (BUI) is a condition that interferes with the enjoyment of a water use. Each BUI has a set of locally-defined delisting criteria that are specific, measurable, achievable, and scientifically-defensible. The Remedial Action Plan (RAP) is administered locally in accordance with the Canada-U.S. Great Lakes Water Quality Agreement (GLWQA) and the Canada-Ontario Agreement (COA). The RAP is an ongoing collaborative effort implemented by federal, provincial, and local governments as well as industry and public partners. There are 3 key stages of the RAP: Stage 1 is a detailed description of the environmental problem; Stage 2 identifies remedial actions and options; Stage 3 is the final document providing evidence that the beneficial uses have been restored and the AOC can be “delisted”. The St. Clair River, a key shipping channel in the Great Lakes Seaway system, flows 64 kilometers from Lake Huron to Lake St. Clair. The St. Clair River is one of five binational AOCs under the Canada – United States Great Lakes Water Quality Agreement (1987). Approximately 170 000 people live in the AOC, particularly in the urban centers of Sarnia, Ontario and Port Huron, Michigan. The St. Clair River has greatly contributed to Ontario's and Michigan's industrial, commercial, and municipal development, and as a result it has been severely degraded due to the improper wastewater management, frequent dredging, and both point and non-point sources of contamination.

    The Turkey Lakes Watershed (TLW) Study was initiated in 1980 by Environment Canada, Natural Resources Canada and Fisheries and Oceans Canada to evaluate anthropogenic perturbation of Canadian Shield ecosystems. Originally, the Study focused on the aquatic and terrestrial effects of acid rain, but now it includes research into the effects of other anthropogenic pollutants (e.g. toxic contaminants) and ecological perturbations (e.g. forest harvesting, climate change and fish habitat modification).

    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/.
