A year ago this month, Matthew Perry suffered a fatal ketamine overdose following a lifelong struggle with addiction. The news became a big Hollywood story, but it was a deeply personal tragedy for Matthew’s family. Tonight, in the actor’s hometown of Ottawa, his family and friends will launch the Matthew Perry Foundation of Canada to support people recovering from addiction. Matthew’s stepfather, the Canadian journalist Keith Morrison (Dateline NBC), joins Tom Power to reflect on his stepson’s life and the work his family is now carrying out in Matthew’s name.
