Okay, thanks.
My second question is about R and D. I'm looking at a report by Natural Resources Canada showing that even among the resource sectors, energy provokes less expenditure than mining and minerals and forestry, at only 0.05% of R and D expenditure, as a percentage of revenue.
Of course, one of the economic benefits to the country, as you've reported, is that we have $100 billion being spent on developing the resources. How much of that money is actually being spent in Canada on R and D, including through pursuing more activity here—upgrading, reclamation, better environmental controls?
I wonder whether Mr. Burt or Ms. Kenny or Mr. McGowan would like to speak to that.
