In the context of ongoing COVID-19 outbreaks in Canadian prisons and jails, I was curious about other times in history that prisoners have faced similar situations and especially times when prisoners have been released as a result. Today's interview is with a local prison historian about epidemics and public health in Canadian prisons, mostly about the 19th and early 20th century. Also some stories about prisoners being released, what health care was like inside and outside of prison walls, and what kind of world people were returning to.
