The National Film Board of Canada has a website with a bunch of their films-- some shorts, some long stuff, some different things, some great stuff. None of the videos are working for me right now, but hopefully they work for you.
Some recommended films ( some I’ve seen and some I want to see )
Carts of Darkness: A documentary about the Grocery Cart racing subculture in North Vancouver.
The Cat Came Back: animated short about a cat that came back… the very next day. Based on a folk song I think.
Blackfly: I saw this on PBS when I was little and absolutely fell in love with it. Once the NFB website is working for me, I hope to fall in love with it again.
The Great Toy Robbery: Santa meets the old West
