BTNX, the Canadian rapid test supplier that won an estimated $2 billion in federal contracts, denied that Health Canada used BTNX’s edited study to evaluate the rapid test kit that the federal government later purchased.

A year-long investigation into federal procurement published by Global News on Thursday revealed that Toronto area-based BTNX deleted dozens of specimens, or samples, from a study it submitted to Health Canada. That evaluation showed how well the company’s test detected COVID-19.
