An anonymous reader writes "Last week, a Canadian Supreme Court decision attracted attention for reduced copyright fees for music and video. Michael Geist has a detailed analysis that concludes there are two bigger, long term effects. First, Canada has effectively now adopted fair use. Second, the Supreme Court has made technological neutrality a foundational principle of Canadian copyright. The technological neutrality principle could have an enormous long-term impact on Canadian copyright, posing a threat to some copyright collective tariff proposals and to the newly enacted digital lock rules."
