lastly, this could be real footage, who knows. some of it looks pretty interesting. but whoever made it and put that canada thing at the beginning is either very misinformed or trying to completely mess people's heads up intentionally. I wouldn't doubt if there are tunnels going all over the world that connect to antarctica. there's a reason that google doesn't let you look at anything down there. the islands I mentioned are specifically blurred out, and they only let you view the touristy part of the main continent.
