Canada's report on artificial intelligence and the administration of justice is divided into three parts. In this first part, we present the technological innovations, powered by algorithms, artificial intelligence and facial recognition, used by police forces in Canada. Although the use of these innovations does not appear to be widespread currently, police forces have a clear interest in making greater use of these predictive technologies in the future. Informed by the experience with these technologies in the United States, civil groups and legal researchers have expressed significant resistance to the biases, lack of transparency, and aura of scientificity that characterize these tools. Taking note of this resistance, we also present the most recent normative innovations in Canada as well as the classic principles of law that could frame the use of these technologies.
