There are tons of YouTube videos I can't see in Canada, though I don't remember the restricted ones being anything other than TV shows/movies which often have a limited broadcast audience.

I do remember an experiment using Tor to surf Google images.  That was surprising.  I noticed that in some European countries (and I mean democratic countries not known for heavy handed censorship) certain search terms just gave me 0 search results.  Trying again from Canada, and I'd get 30,000 results. Hmmm.

ETA: I wish I'd made note of my observations, but I honestly can't remember exactly which countries or which seach terms.  I should repeat the experiment and take notes.
