Any of the changes to the upper chamber proposed by Stephen Harper thus far amount to an attempt to shift power from Central Canada to the West without having to shift the requisite bodies out West to force a redistribution of power in the HOC, which is based more or less on rep. by pop.
On the political level, an NEP in reverse, in other words.
Ontario and Quebec MPs of all stripes should oppose any such changs. Abolition should be the only reform acceptable to Central Canada.
(But of course talk of Senate reform at this point is simply a slice of red meat waved before the Tory base. It isn't like Harper is serious about pushing Senate reform in the face of a looming recession and looming deficits. But if he ever got serious about it, that's what I would say.)
