New legislation making its way through the U.S. Congress has placed a TikTok ban back on the public agenda. The bill – which would lead to either a divestiture or ban – has passed the House of Representatives and is now headed to the Senate. On the Canadian front,  TikTok is already prohibited on government devices at the federal level alongside some provinces, the government has quietly conducted a national security review, and there are new calls to ban it altogether from the Canadian market.   Anupam Chander is a law professor at Georgetown University and leading expert on the global regulation of new technologies. He joined the Law Bytes podcast several years ago when a TikTok ban was raised by the Trump Administration and he returns this week to discuss the latest developments and their broader implications.
