Airports and industries should be required to publicly disclose their use of facial recognition, while the National Security and Intelligence Committee of Parliamentarians should review any military or intelligence use of the technology, they said. Tamir Israel, a lawyer with the Samuelson-Glushko Canadian Internet Policy and Public Interest Clinic, testified at the committee that travelers might not be aware they're subject to the technology, such as at the customs screening mechanism at the Pearson Airport in Toronto. The government should disclose its own acquisitions of the technology, and "create a public AI registry in which all algorithmic tools used by any entity operating in Canada are listed," MPs said. Privacy lawyer Carole Piovesan told the committee that while discussions on FRT "tend to focus on security and surveillance," the technology is also used by other sectors, including health care, retail and e-commerce, and telecom and IT. The technology is also more accurate in identifying white individuals, and less accurate in identifying people of colour.
