The National Film Board of Canada has a cool library of films that you can view online, but if you're in downtown Toronto, the NFB Mediatheque is one of my favourite stops. They feature ultra comfy, ultra convenient digital viewing stations with an incredible library of 4,600 films you can view - and it's all free too. The only thing you'll need to watch for is groups of school children on weekdays, and check the calendar for weekend events that can take up the space. I love the ultra modern vibe and - natch - the films! There are lots of free screenings, and workshops that can give you the basics of animation and other techniques. It's a real hidden gem right in the Entertainment District at John & Richmond.
