    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 partnership with the provinces, territories and other agencies, WSC operates over 2500 active hydrometric gauges across the country, maintains an archive of historical information for over 7600 stations and provides access to near real-time (water level and stream flow) provisional data at over 1700 locations in Canada.

    Historical water quality data measured on a continuous basis at over 23 locations across Canada is included in this dataset. Most locations include hourly temperature, dissolved oxygen, pH, specific conductance and turbidity. Data are collected by Environment and Climate Change Canada (ECCC) and in partnership with other federal departments and provinces and territories to enable the detection of short-term water quality events, and to determine trends in water quality, especially at transboundary sites (or Federal waters) in support of Federal legislation and international agreements, or to report on the status of Government of Canada priority aquatic ecosystems.

Monitoring activities are underway to collect suspended sediment samples in the Lower Athabasca River. These monitoring activities include measurements of physical characteristics, concentrations and sediment loadings collected using Water Survey Canada standards. Sediments will also be collected using a continuous flow centrifuge and analysed in the laboratory for sediment quality variables as per Appendix B in the Integrated Monitoring Plan. The river bed sediments in the Lower Athabasca are known to shift and migrate downstream. Monitoring to generate bathymetric maps of the bed-channel morphology over time ids underway and will allow for determination of bed sediment transport downstream, and will also be useful in calibration/validation of sediment/bitumen erosion/transport/deposition models

    This file is produced by the Transportation Division of Environment and Climate Change Canada (ECCC). It contains basic information summarizing notices of defect and other company notifications submitted to ECCC. The purpose of the file is to disseminate information pertaining to emission-related issues on vehicles, vessels, and engines. It does do not imply any position on the part of ECCC with regard to these notices of defect and other company notifications. Please note that some details may not have been made available by the companies at the time of their submissions. If this is the case, certain fields will appear blank. Incomplete entries will be updated once the information becomes available. The file can be accessed from the Data Resources Section below.

    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 (ECCC) as well as through the Canada-Quebec Water Quality Monitoring Agreement and the St. Lawrence Action Plan to assess water quality status and long-term trends, detect emerging issues, establish water quality guidelines and track the effectiveness of remedial measures and regulatory decisions. Data for sites operated by the province are available from Quebec's Sustainable Development, Environment and the Fight against Climate Change Ministry.

    National Water Monitoring Program for Pesticides (NWMPP) water quality data are presented for a network of freshwater sites across Canada. A two-year pilot program is being conducted in partnership between Health Canada (HC), Environment and Climate Change Canada (ECCC), and Agriculture and Agri-Food Canada (AAFC), with additional partners listed below. Data comprise a suite of approximately 185 pesticides from a limited number of surface water sites in Canada. Sampling frequency and collection of ancillary data vary among locations; however, in general, samples are taken twice per week during the growing season. Ancillary data can include physical-chemical parameters such as temperature, pH and specific conductance. The main objective of the pilot program is to provide lessons learned for the development of a framework, which will provide guidance for pesticide monitoring programs, including a NWMPP. The expected outcomes of the framework and the NWMPP are enhanced knowledge about the levels of pesticides in the aquatic environment, expanded partnerships, improved collaborations, and increased accessibility of information through Open Data.

    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, nutrients and metals. The number of sites varies from year-to-year, and sampling frequencies vary from one location to another, as surveillance activities are adjusted according to evolving environmental pressures and governmental programs. Data are collected in order to determine baseline water quality status, determine event-based pulse concentrations, evaluate the effectiveness of management actions, verify compliance with water quality objectives, and/or identify emerging issues. Additional information on the surveillance project allows suitable data interpretation and can be obtained by contacting the data authority. More pesticides data are available as part of the National Long-term Water Quality Monitoring Data.
