A Look Into Old Barrie! Barrie, ON, Canada / 93.1 Fresh Radio June 26, 2016 12:20 pm I love history, but I love local history more! I saw an article about the Old Barrie post office. No not the former one on Collier Street, the original post office that was located in what is now Fred Grant Square! You can watch a home video, narrated by 2 gentlemen, talking about some of the events that were going on in Barrie during the end of the second world war. You can read the whole article here!
