My understanding is that there are discussions taking place in Canada and in other countries, especially where there is a large workforce, about how people will be able to return to the workplace and be safe.
In that context, they are designing, developing and looking to implement contact-tracing apps within the workplace. They will basically monitor where people are within the workplace, who they interact with, where they move about and what their patterns of movement are within the workplace, so that if there is an outbreak of COVID-19 or if an employee is diagnosed with COVID-19, other employees can be notified and appropriate measures can be taken.
On the one hand, you can understand how important that is for getting people back to work and keeping them safe, but at the same time, that's a very significant level of surveillance. I think it raises privacy issues that we need to be thinking very seriously about when we put protections and balancing factors in place.
