I think it's because Harper and Co. know that there are proposals for a world water bank for which Canada would be asked to contribute heavily to. By not being there, they can't be blamed for refusing the plan, and it would sound silly for a plan to be formulated that makes Canada a big contributor when Canada isn't even there to begin with, it would be seen as a hostile move even by Canadians, the equivalent of countries agreeing to take Canada's water. So by not being there, this plan can't even be formulated with Canada as part of it.
It's preemptive, they know what will be discussed.
It's a fair point, but one of the key maxims of diplomacy is that you don't win negotiations by avoiding the table.
Foresighted withdrawal or not, foreign policy can't be about taking your ball and going home when you no longer want to play. The game continues without you, and you can either be a part of it and shape the rules, or have the international community force them upon you when you regain your composure and decide to join again.
