Toronto Pearson is located in Mississauga, west of Toronto, in Ontario, Canada. It is Canada's largest airport and the sixth-most-connected airport in the world. "As the first airport in the world to test HEXWAVE, we see the potential benefits of utilizing this innovative solution as part of our broader airport security program following further testing and evaluation," said Dwayne MacIntosh, Director, Corporate Safety and Security, GTAA. "We were impressed with the HEXWAVE's seamless screening during beta testing and look forward to working with Liberty Defense on the enhanced detection the HEXWAVE would bring to the airport." HEXWAVE uses millimeter wave, advanced 3D imaging, and AI to detect all types of concealed metallic and non-metallic weapons and other prohibited items – without having to divest common items.

Experts discuss how artificial intelligence is being used to protect venues by screening for items such as bombs, guns, and knives. Artificial intelligence, or AI, is being used to help secure sites from sports arenas to churches and schools. The technology is being used to scan for weapons, including guns, knives and explosives as people walk between standing panels. If a weapon is spotted, security standing by is alerted. Massachusetts based Evolv has used the technology to scan roughly 300 million people across the country since the system went live in 2019, second only to the TSA.

In 2014, scientists at MIT began working to develop an artificial intelligence-powered security system. Atlanta-based company Liberty Defense licensed that technology, called Hexwave, and is now making it commercially available for sports stadiums and other venues. Hexwave uses AI to search for potentially dangerous metallic and non-metallic objects. The system uses radar to scan an individual, then creates a digital 3D image from which it can determine whether the person is carrying a possible threat such as a weapon or a bottle of alcohol. The entire scanning and decision process takes less than 0.2 seconds, reducing the amount of time that is usually taken for fans to file through security scanners when entering sports stadiums.
