Unraveling the Winnipeg disease lab mystery

Since 2019, questions have swirled around why two scientists, originally from China, were marched out of a high-security infectious disease lab in Winnipeg. They were later stripped of their security clearances and fired, in a case that has raised suspicions about Chinese espionage, and prompted calls for the Liberal government to release more information.

Now, at least some questions have been answered. Last week the federal government released hundreds of documents, largely from Canada’s spy agency, CSIS, about the scientists’ dismissal. The documents contain revealing insights — but also leave many questions unanswered, putting further pressure on the government to allow a deeper investigation into this story.

Today CBC reporters Karen Pauls and Catharine Tunney join us to dive into the revelations in these documents, the political firestorm they’re causing, and what questions remain unanswered.
