I'm happy to talk about the pilot project that Public Safety and the RCMP ran with seven different police forces across the country. I'll ask Ms. Huggins to speak specifically about the false positive rates.
As you indicated, the pilot was run across the country in December, in seven jurisdictions, for about 12 weeks. We tested the device to see whether it operated well under different weather and lighting conditions, and so on. We found that officers were very comfortable with the device. The devices perform very well under different weather conditions. This was deliberately run between December and February or March, because of our great Canadian winters. They performed very well.
There were some experiences that will inform the development of standard operating procedures, like some of the saliva samples freezing after eight minutes, but overall the pilot worked very well.
The devices will have to still be accredited according to standards that are being developed right now by the DDC. These were two amongst many that are on the market. It was very encouraging and prompted us to move to include it in the proposed bill.
I'll just ask Ms. Huggins to speak to the false positive rate.
