Setting the Standard for eDNA: A Canadian-led effort to turn data into trusted action

December 27, 2025

What if a single water sample could reveal everything in an ecosystem, from fish to frogs to invasive species, without disturbing a single creature? That’s the promise of environmental DNA, or eDNA.

However, for eDNA to support genuine conservation efforts, the data must be credible, comparable and collected with care. Canada is leading the way on this significant challenge.

Building on work through the iTrackDNA initiative, Canadian researchers, regulators and Indigenous partners came together and, in 2021 and 2023, created the country’s first national standards for eDNA collection. These new CSA standards are now in place to guide the collection, storage and analysis of samples, ensuring results are trustworthy and legally defensible.

The next step is making those results easier to use. Led by Caren Helbing (University of Victoria) and Rachel Meyer (UC Santa Cruz), eDNA Explorer Canada is adapting a powerful data-sharing platform to meet Canadian environmental laws and sovereignty requirements. Designed with open access in mind, the tool enables communities, scientists and governments to explore and compare eDNA results in real time.

Together, the standards and the platform are doing more than organizing data — they’re building the foundation for credible, transparent biodiversity monitoring in Canada.
