Environment and Climate Change Canada

We publish Canada’s greenhouse gas (GHG) and air pollutant emissions projections each year. The GHG emissions projections help us measure progress in reducing greenhouse gas emissions and combating climate change. GHG emissions projections are presented for a few scenarios. The air pollutant...

As part of a scientific assessment of critical habitat for boreal woodland caribou (Environment Canada 2011, see full reference in accompanying documentation), Environment Canada's Landscape Science and Technology Division was tasked with providing detailed anthropogenic disturbance mapping,...

The Acid Sensitive Lakes Study in the Atlantic Canada was initiated in 1983 by Environment and Climate Change Canada, to evaluate the impact of acid atmospheric pollutant on aquatic ecosystem. Originally, the study focused on the aquatic and terrestrial effects of acid precipitation, but now it...

In the oil sands air monitoring component, nitrogen dioxide (NO2) and sulphur dioxide (SO2) levels are monitored by ground-based instruments, satellites and other measurements. Monitoring of air pollutants from satellites is becoming an alternative to surface and aircraft measurements, and allows...

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.)...

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. This database contains the full NPRI dataset from 1993 to the current reporting year. To help you navigate, a Microsoft Word file...

The Canadian Protected and Conserved Areas Database (CPCAD) is the authoritative source of data on protected and conserved areas in Canada. The database consists of the most up-to-date spatial and attribute data on marine and terrestrial protected areas in all governance categories recognized by...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Water quality in Canadian rivers indicator provide a measure of the ability of river water across Canada to support...

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...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Species at risk population trends indicator shows whether the population and distribution trends of species at risk are...

"The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Ecological integrity of national parks indicator summarizes the condition (good, fair, poor) and trend (improving,...

This dataset contains annual algal bloom indices (duration, extent, intensity, severity) summary statistics (maximum, mean) over the June through October monitoring period for Lake Winnipeg. These data are derived from satellite remote sensing algorithms using European Space Agency's (ESA's)...

This dataset contains annual algal bloom indices (duration, extent, intensity, severity) summary statistics (maximum, mean) over the June through October monitoring period for Lake of the Woods. These data are derived from satellite remote sensing algorithms using European Space Agency's (ESA's)...

This dataset contains annual algal bloom indices (duration, extent, intensity, severity) summary statistics (maximum, mean) over the June through October monitoring period for Lake Erie. These data are derived from satellite remote sensing algorithms using European Space Agency's (ESA's) MEdium...

Surface freshwater quality monitoring in the Fraser River Basin is carried out under the Canada-British Columbia Water Quality Monitoring Agreement. Monitoring is conducted to assess water quality status and long-term trends, detect emerging issues, establish water quality guidelines and track...

Population trend estimates based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. The trend results are Canadian trends and thus use data from Canadian BBS routes only. Results are updated annually; these estimates use BBS data...

This collection houses PDFs of active BBS route maps, which are grouped by province or territory. These maps allow BBS volunteers in Canada to easily locate the start of their route, and to navigate the official route. The BBS is jointly coordinated by Environment Canada's Canadian Wildlife...

Acoustic Doppler Current Profiler(ADCP) data was collected during the summer months of 2017 in the Randle Reef area of Hamilton Harbor. The data is used to validate a three dimensional MIKE3-FM hydrodynamic and mud transport modeling system. The model is used to study the hydrodynamic...

Archived population trend estimates, based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. These archived estimates use data from Canadian BBS routes only, collected from 1970 through 2011. Trends are presented for species,...

Canada has the longest coastline in the world, measuring 243,790 kilometers. Many of our waterways along the coastline have to be dredged regularly to keep shipping channels and harbours open and safe for navigation; and this material is sometimes best disposed of at sea. Schedule 5 of the...
