MONTREAL -- There are new privacy and security concerns over the QR codes given out to Quebecers as proof of vaccination. A cyber security team of experts tested whether or not it could crack the codes and they say they were able to do so fairly easily. While the roll-out of the QR codes has already begun, only a few details have been released about how and when they will be used. Health minister Christian Dubé has said that if the epidemiological situation deteriorates in Quebec, the QR codes will be required for residents to access some non-essential services, such as bars and gyms.
