If Canada is going to keep COVID-19 under control, contact tracing and tracking will have to play a huge part in it. You hear about contact tracing in every interview or article about controlling the virus—but how does the process actually work?

Who are the people tasked with the often difficult job? How do they deal with people who are scared or angry to hear from them? How many cases can be missed before an outbreak looms? And as Canada prepares for a second wave...do we have enough of them to handle what's coming?
