## In brief

- The Narwhal reports that Ottawa's own water tests keep detecting high-risk pesticide chemicals.
- The report says these detections continue even as the federal government loosens pesticide rules.
- The article features Gérald Chouinard, a former Quebec agronomist who advised apple growers on reducing pesticide use for 30 years.

## Why it matters

Government water testing that detects high-risk pesticides while regulations are relaxed bears directly on how exposure is monitored and how safety thresholds are set.
