One way to look at this is to look at what is currently happening in Australia. Canada was the largest destination for mineral exploration spending until about 1992. Then things started to turn, and Australia took over first place. In 2002 Canada became number one again, and we've been number one ever since.
Right now there is an outflow from Australia because of tax measures being taken there with super-tax policies. The carbon tax they introduced has been very controversial. Canada is a beneficiary of this. Australia is probably our largest competitor in the world, and now we attract the largest share of global exploration and investment. The $137 billion I referred to is just potential new mining investment, and it speaks to the importance of having a competitive tax climate.
