VANCOUVER -- The mother of an inmate at a prison in B.C.'s Fraser Valley says her son and other prisoners have been asking for masks and other personal protective equipment since the start of the COVID-19 pandemic, but weren't given any until several people in their cohort had tested positive for the disease. "Each tier, I'm sure, is asking for gloves, for masks, but my son's tier didn't get any until they were all positive," said Tery, who asked CTV News Vancouver not to share her last name out of concern that her son could face repercussions for her speaking out.
