Information received in response to the data gathering initiative on certain substituted diphenylamine substances (2012). To increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is providing the summary of the information...

Long-term freshwater quality monitoring data for over 10 sites in the Pacific Coastal Basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada...

The Canadian Brewer Spectrophotometer Network (CBSN) monitors the total thickness of the ozone layer (known as total column ozone) and ultraviolet (UV) radiation at selected monitoring locations across Canada. The objectives of the network are to provide long-term stratospheric ozone data for...

This data collection contains precipitation concentration data of anthropogenic organic pollutants in precipitation (AOPP). Some of these AOPPs reported in this data collection are considered toxic substances (e.g. polychlorinated biphenyls, PCBs; polycyclic aromatic hydrocarbons, PAHs; some...

Information received in response to the notice with respect to certain aromatic amines and aromatic azo and benzidine-based substances (2011). To increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is providing the summary of...

The generation of geospatial thematic information for managing and monitoring Canada's boreal ecosystem is essential for researchers, land managers, and policy makers. Canada's boreal region is a vast mosaic of forests, wetlands, rivers and lakes, but anthropogenic disturbances have impacted...

The Canadian Ozonesonde Network measures vertical profiles of ozone from ground level up to 36 km altitude across Canada. The objectives of the network are to provide long-term stratospheric and tropospheric ozone data for periodic assessment of the state of the ozone layer, to validate satellite...

The purpose of Bird Conservation Regions strategies is to summarize the important issues and to recommend the actions required to conserve populations of birds in Canada. The Bird Conservation Regions (BCR) used as the basis for our planning units are based on the Commission for Environmental...

The CanESM2 large ensembles are 50-member perturbed initial condition ensembles from 1950 to 2020, with all historical forcings (historical), solar and volcanic forcings only (historicalNat), anthropogenic aerosols only (historicalMisc, p4), and ozone only (historicalMisc, p6). The model,...

At all locations the TGM measurements were made using automatic Tekran ® 2537 mercury vapour analyzers (described in detail in Poissant, 1997). The air is typically sampled at flow rates between 1.0 and 1.5 L/min (depending on location) and is passed through a Teflon filter (47 mm diameter; 0.45...

This notice applies to owners of dental facilities that perform activities in relation to dental amalgam or elemental mercury. This notice has been in effect since May 8, 2010, for owners of dental facilities. Although the initial facilities subject have completed their obligations, this notice...

Ambient concentrations of speciated mercury (Hg) have been measured at many locations across Canada. Mercury in the atmosphere is measured in three operationally-defined forms - gaseous elemental mercury (GEM), reactive gaseous mercury (RGM), and particulate-bound mercury (PBM). Under most...

This notice applies to owners of facilities that manufacture or use greater than 100 kg of bisphenol A per year (alone or in a mixture), release effluents containing bisphenol A, and are involved in the activities specified in the notice. This notice has been in effect since April 14, 2012, for...

Long-term freshwater quality monitoring data for over two sites in the Okanagan - Similkameen Basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change...

The Climate Research Division's climate modelling program provides climate model output for the climate science and climate change research community, nationally and internationally. This dataset includes global Earth System model output (from several generations of models), regional climate...

Measurements of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate bound mercury on PM2.5 (referred to as PBM2.5) were collected by Environment and Climate Change Canada from August to September 2013 at the Wood Buffalo Environmental Association (WBEA) Air Monitoring...
