If I could, I'll add a supplementary.
I noticed that there was a survey by Canadian Manufacturers and Exporters. A lot of them are anticipating a better year in 2007 than they had in 2006, with higher demand and potentially more employment. It would seem to me that maybe that could be pointing, even though the dollar is higher, towards their actually improving their productivity. Or is it just a little bit of optimism on their part?
