The mask has become a symbol of all we’ve been through in the age of the pandemic. Amy Dempsey traced the trajectory of Toronto’s “mask life” and joins “This Matters” to talk about how a piece of cloth became both protection and a political symbol. As well, we mark the “maskiversary,” one year since the day Prime Minister Justin Trudeau advocated mask wearing and warned of “speaking moistly.” Guest: Amy Dempsey, Toronto Star’s investigative feature writer
