Environmental monitoring involves collecting and analyzing information on the state of the environment in order to identify changes and trends over time. An integral part of scientific research, it is also a means of verifying whether policies and programs are having the desired results and activities are in compliance with legislation.
Environment Canada monitors everything from climate and weather conditions to wildlife populations and water levels. It also analyzes samples of air, water, soil and tissue for pollutants. This section provides information on these and other departmental monitoring efforts.
Find information about biological effects monitoring in Canada and the effects of acid rain on aquatic ecosystems.
This map shows ambient air monitoring sites operated by provincial and federal governments in the Atlantic Region.
This repository contains aquatic biological information such as in situ stream measurements, geo-reference information and benthic invertebrate taxa photographs.
This network of reference sites is available to users interested in assessing the biological health of freshwater in Canada.
This database contains air and precipitation chemistry data from many major regional-scale networks in North America.
Monitoring and inventory programs are key ways in which Environment Canada, along with provincial and territorial partners, gathers data about the quality of our air and sources of pollution.
Find information here on how organizations and individuals involved in ecological monitoring in Canada work together to detect, describe and report on ecosystem changes.
Learn about environmental effects monitoring as an assessment and decision making tool to protect aquatic ecosystems. Find technical guidance and information about legal requirements.
This network was established by Canada and the United States to monitor air and precipitation in the Great Lakes Basin.
Find reports, databases and newsletters related to the population monitoring of birds, which provide data on whether numbers are increasing or decreasing over time and supply key information to support migratory bird conservation programs.
Verify and understand better the quality of meteorological forecasts by using the graphs, equations, and evaluation reports found here.
Access the National Pollutant Release Inventory to find information about releases, disposals and recycling of pollutants in Canadian communities.
This section contains environmental indicators that describe the state of the environment for particular issues in a scientifically concise and easily understood manner.
This section describes the work of scientists at the National Atmospheric Radiation Centre, who measure the amount of energy entering and leaving the earth's atmosphere and ensure that these measurements made in Canada are comparable with similar measurements made throughout the world.
This section presents overviews of important environmental issues, designed to translate science and data into information and knowledge that can be used by decision-makers. Resources and tools for indicator and reporting practitioners are also included.
These pages provide more recent data on a number of issues covered on the original State of the Environment CD-ROM.
This section includes the Brewer Spectrophotometer Network, the Ozonesonde Network and the Ozone Mapping Program. It provides data in graphical form for ozone values and UV Index measurements.
This report provides an overview of the status and trends of some key environmental issues of concern to Canadians.
