I think it was, first and foremost, carrying out its responsibilities as a member of the concert of nations.
Secondly, it was to occupy a space that was very uncomfortable, and that uncomfortable space is the fact that the Canadian government has said, pretty much out loud, what some other countries believe: that the process has reached its peak in the context of Kyoto and the next step has to be much broader.
That said, up to now Canada has not abided by its obligations under Kyoto, and chances are it won't get there by 2012. That's the pragmatics of it, and that's what makes it difficult for Canada to come to a large forum and tell people what to do. But I do think that Canada, in the context of the G-8, the Gleneagles +5, plus the MEM, can play a more substantive role precisely because I think it's in Canada's interest to broaden the base of the instruments we'll give ourselves to face what is a real, collective world issue, not only a Canadian issue.
The palette of options, which by definition will be opened in a dialogue with major developing countries, which I personally call the new industrial countries, might give a space for Canada to make a major contribution in a context where the world moves forward, not only a fraction of it.
