Actually, Canada has similar fair use and libel laws as the US. We tend to abide by the DMCA, though our laws are actually Notice and Notice. All appropriate sites are deemed safe harbours, too. To keep things simple, since I am not a lawyer, our laws began with British roots, but we do so much business with the US that ours have changed to make our relations with the US easier.
The biggest difference between our Canada and the US are those three basic Rights. In the US, its Right to Life, Liberty and Pursuit of Happiness. In Canada its Right to Life, Liberty and Security of Person. We have stricter anti-Hate laws. Groups like Westboro Baptist have a much harder time here. We're very much more protective of our Rights to Freedom of Speech and Freedom of Personal Expression.
There are other considerations, too. When the recession hit, our economy rebounded faster due, in part, to different banking regulations. We have stricter consumer protection laws. Free universal health care and education.
