On the GST studies issue, I'll have to get one of the departmental staff to speak to that.
On tax reductions, we've reduced taxes of every kind in Canada, including the personal income tax, since we came into office. Certainly we've reduced the consumption tax by two full percentage points. This is being reflected now, and Canadians know it, because they're filling in their tax forms and are seeing the size of their rebate cheques. This is something that is well known and has recently been communicated to me every day by people across Canada, who are saying how happy they are to be getting higher rebates than they expected.
On the question of the studies showing the benefits of the GST cuts for consumers, I'll get my colleague to respond.
