Canada’s Migration to Post-Quantum Cryptography: Public-Private Roles

Special Report

October 29, 2025

Technological advancement drives innovation, but it also comes with risk. Sectors such as finance, health care, defence and telecommunications depend on these developments to stay ahead of the curve. While emerging dual-use technologies such as quantum computing hold tremendous promise, they can also undermine current cryptographic systems, making them vulnerable to attacks that compromise sensitive data across the public and private sectors. Aimed at policy makers and cybersecurity actors, this special report highlights the federal government’s role in regulating these technologies and mitigating quantum threats while protecting critical systems and public trust.
