Canada facing fresh U.S. pressure to agree to review cross-border mining toxins

Mar 24, 2023 | 8:38 AM

WASHINGTON — President Joe Biden is expected to add today to the pressure on Canada for a bilateral investigation into toxic mining runoff in a key cross-border watershed. 

Activists, experts and Indigenous leaders in both Canada and the U.S. want an investigation into toxins from B.C. mining operations they say have been polluting the Kootenay River basin for decades. 

The “reference,” as it’s known, would be overseen by the International Joint Commission, a bilateral body established by the Boundary Waters Treaty of 1909. 

Both countries must agree to a reference — and Canada has been reluctant, despite pressure from Indigenous groups, conservationists and even the U.S. State Department.
