TWD (Tap Water Database) is designed as a reference and informational tool. It presents reported water quality data in a clear and accessible format to support general understanding of tap water testing results. TWD provides public access to tap water quality information across Canada. The Database aggregates and displays publicly available water testing data to allow users to explore reported contaminant levels by location.
Click on any city marker, or use the search bar to find specific cities, to explore available water quality data, reported contaminant levels, and source reports.
City markers are colour-coded for visual reference only, based on how reported contaminant values compare to selected reference benchmarks.
Important: Colour indicators are not safety determinations, do not indicate regulatory compliance or non-compliance, and should not be interpreted as health advice.
All data is sourced from publicly available records, including governmental and municipal sources. Information is provided without any guarantee as to accuracy, completeness, or currency and may be updated or corrected from time to time without notice.
The information is updated as new reports become available, typically monthly or quarterly depending on the city's testing schedule.
References to Health Canada, provincial health authorities, municipalities or third-party organizations do not imply affiliation, endorsement, or approval by those entities.
Water quality data shown here is based on publicly available sources and is provided for general informational purposes only. Results may not reflect conditions at a specific building, property, or tap, including variations due to plumbing, infrastructure, or sampling timing.
Comparative benchmarks shown are non-regulatory reference points only and do not indicate regulatory compliance or non-compliance, safety, or health risk. Any benchmarks or guidelines referenced are provided for comparison only. They are not legal standards and do not constitute regulatory limits.
This information should not be considered as professional advice or a substitute for consultation with qualified professionals or laboratory testing.
