Ted Barris is the author of many books about Canadian experiences in the Second World War. His latest is, "Battle of Britain: Canadian Airmen in Their Finest Hour." In this conversation, available exclusively online, he talks with host Jeff Douglas about the origins of the RCAF.

Brian MacDonald is the former executive director of Aman Lara, an organization of volunteers and veterans that perform 'extractions' from Afghanistan. That began in 2021, following the collapse of the Afghan government and the return to power of the Taliban. So at first, the organization's main focus was helping Afghans escape their country. This work expanded in 2022, to helping people get out of Ukraine. Two years ago, Brian stepped away from his role at Aman Lara, to start an organization called Utimus. It has a large focus on getting newcomers to Canada the qualifications they might need to join the workforce here. Utimus is based mostly in Ontario, but the CEO and founder, Brian, is located in Fredericton, New Brunswick. Here's his conversation with host, Jeff Douglas.

On a Maritime-wide edition of Mainstreet from Halifax, host Jeff Douglas plays archival audio of Sergeant (Ret'd) Tyson Bowen, who gave 14 years of his life to the Canadian Armed Forces, including two combat tours in Afghanistan. Then Jeff speaks with Tyson's sister Tanya Browne, from our studio in Fredericton, New Brunswick. In spite of all he had done with his life, Tyson was just 35 years old when he died on September 3. 2022.
