I can't say too much, because we're actually involved in a case before the B.C. commissioner. However, there's a very good article in The Tyee, one of the new media based in British Columbia. They did a very extensive review of that case, and I recommend it to you.
As far as we know, only the Government of British Columbia has done this so far. Essentially they chose certain selected requesters who went through the system and finally got their documents beaten out of the government. The government sent with those documents what they called a “helpful” letter, saying this to the requesters: The documents being released to you through the Freedom of Information and Protection of Privacy Act are subject to crown copyright, and therefore you can look at them yourself in the privacy of your own home, but if you want to put them up on the Internet, then you have to get permission from the intellectual property branch of the Government of British Columbia.
We have a bit of a problem with that. Michael Geist has also written about this in his blog. Essentially, there are single-digit applications of this act in terms of defending crown copyright. If you are looking for economies to make, maybe that's the place to be looking.
