I can tell you that at the very earliest, we modelled ourselves on American copyright law. In effect, some of the recommendations we have—to adopt an American fair use-style provision, for example—are actually quite consistent with our history. However, we're talking about over 200 years of history.
Although Canada has chosen traditions and had traditions imposed on us in the 20th century—the British tradition particularly—we've always taken some elements from the French, British, and American and incorporated them into things that are uniquely Canadian, to try to develop the flexibilities we need to manoeuvre.
In a sense, the quick answer is that it's all of the above, but we've done it differently and our approach has been different.
