Long-term freshwater quality monitoring data for over five sites in the Keewatin - Southern Baffin Island 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...

Long-term freshwater quality monitoring data for over eight sites in the Ottawa 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 Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada’s performance on key environmental sustainability issues. The data collection contains datasets that track water quality within Canada. The Water quality in Canadian rivers indicators...

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 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...

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 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

Jackfish Bay was identified as an Area of Concern (AOC) in 1987 due to degraded water and sediment quality and environmental health, which included impairment to benthic communities. As part of the Great Lakes Action Plan, assessments of benthic conditions in the Jackfish Bay AOC have been...

At offshore sites, triplicate Ponar grabs (0.052 m-2) of sediment were collected from the M/V Namao. At nearshore sites, sediment samples were collected from a smaller workboat using a Petite Ponar grab (0.023 m-2) at the 3 m depth contour. Total sampling effort varied across the three years...

Long-term freshwater quality monitoring data for over 13 sites in the Columbia 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 (ECCC)...
