Water level and discharge data are available from Water Survey of Canada’s Hydrometric Network. The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In...

Long-term freshwater quality monitoring data for over 40 sites in the St. Lawrence River 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 Pacific 2001 Air Quality Study (PAC2001) was conducted from 1 August to 31 September, 2001 in the Lower Fraser Valley (LFV), British Columbia, Canada. The study consisted of a number of research projects organized to address several issues related to ambient particulate matter and ozone. A...

This site provides public access to real-time hydrometric data collected at over 1800 locations and access to historical data collected at over 7600 stations (active and discontinued) in Canada. Hydrometric data are collected and compiled by Water Survey of Canada’s eight regional offices and...

High-resolution statistically downscaled climate indices relevant to climate change impacts in Canada are available at a 10 km spatial resolution and an annual temporal resolution for 1951-2100. The climate indices are based on model projections from 24 global climate models (GCMs) that...

Observations on various types of wetlands, terrestrial environments, and vascular plants for 55 sites visited in 2012 and located in in the Boucherville Islands are included in this dataset. Since the 1990s, Environment and Climate Change Canada (ECCC) has been monitoring changes in wetlands...

The Stanley Park Winter Waterbird Survey, 1995-2019, was made possible through a co-operative effort between Environment and Climate Change Canada, the British Columbia Institute of Technology’s Wildlife and Recreation Program, and the Stanley Park Ecology Society. The intent of the survey is to...

The Pulp & Paper Effluent Regulations (PPER) were published in 1992 pursuant to the Fisheries Act to control effluent discharges and reduce the impacts of effluents on fish and fish habitat that had been observed at pulp and paper mills across Canada at that time. The Regulations set out...

One of the ways of obtaining local-scale climate change scenarios is to use regression-based statistical downscaling of GCMs. In this approach, an empirical relationship between GCM predictors (i.e., near-surface and upper-level atmosphere circulation variables) and surface predictands (such as...

This notice applied to owners of facilities that manufactured synthetic rubber using acrylonitrile which resulted in releases of acrylonitrile to the environment. This notice was in effect from May 24, 2003, to May 31, 2007, for facilities involved in the manufacture of synthetic rubber. It is...

The Canadian Ice Service maintains a collection of Daily ice charts, Regional ice charts and Iceberg charts. These charts are available in GIF format and E00 Regional Charts only .

The Canadian Environmental Sustainability Indicators CESI program provides data and information to track Canada's performance on key environmental sustainability issues. The Air Pollutant Emissions indicators track the total emissions of key air pollutants from anthropogenic human-related...

The Canadian Environmental Sustainability Indicators CESI program provides data and information to track Canada's performance on key environmental sustainability issues. The International Comparison of Air Pollutant Emissions indicators track air pollutant emissions for Canada and nine other...

Pesticides surveillance data in freshwater from federal and federal-provincial sites at various locations throughout Canada are included in this dataset. Measurements mostly include pesticides but could include physical-chemical parameters such as temperature, pH, alkalinity, major ions,...

The toxicity of pharmaceuticals finasteride (FIN) and melengestrol acetate (MGA) was assessed in chronic (42 days) sediment tests with the amphipod Hyalella azteca. Two tests were completed for each compound. Survival, growth, reproduction and sex ratio were assessed at the end of each test.

The recent (2017) spatial patterns of zooplankton communities in 73 Québec lakes distributed over an 800-km SW-NE gradient, spanning a wide range of water quality and climate. Results were published in a scientific article that can be found here: https://doi.org/10.1139/cjfas-2020-0139

The toxicity of pharmaceuticals finasteride (FIN) and melengestrol acetate (MGA) was assessed in freshwater mussels, including an acute (48 h) aqueous tests with glochidia from Lampsilis siliquoidea, a sub-chronic (14 days) sediment test with gravid female Lampsilis fasciola, and chronic (21 and...

Ambient air is sampled daily, with a nominal 24-hour sampling period, on a Canadian Air and Precipitation Monitoring Network (CAPMoN) sequential sample head located 10 meters above ground. Air is drawn through a three-stage filter pack consisting of 47-millimeter Teflon, nylon and cellulose...

This dataset includes historical observations of the daily depth of snow on the ground (daily climate element 013) made at Environment and Climate Change Canada (ECCC) sites by manual ruler or by a sonic sensor equipped autostations. The history of the ECCC daily snow depth observing program is...
