Canadian Air Quality: Peak Fine Particulate Matter Concentrations at Monitoring Stations

Environment and Climate Change Canada provides data on ambient concentrations of fine particulate matter and other pollutants at national, regional, and urban levels. The Canadian Environmental Sustainability Indicators program tracks performance on key environmental issues, offering information via maps, charts, and downloadable data tables. The dataset was last updated on 2026-04-28.

Use Cases

• Modeling spatial patterns of air pollution based on monitoring station data.
• Analyzing trends in peak fine particulate matter concentrations over time.
• Assessing environmental sustainability indicators for policy reporting.
• Creating visualizations of air quality data at national and regional scales.

Strengths

• Data is provided by the authoritative national agency, Environment and Climate Change Canada.
• Information is offered in multiple formats including CSV, GeoJSON, and interactive maps.
• Coverage includes national, regional, and urban area levels as well as local monitoring stations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the monitoring network.
