Finally, Mr. Williams, from an international perspective—because you're probably the best placed of the witnesses here today—how much of a leadership role has Canada been playing with respect to these offices and this approach?
I think you mentioned in your remarks—help Canadians understand, if you could—the extent to which making this position real in Canada was an institutional response. It was the government's response to the Brundtland Commission and the 1992 Rio Earth Summit. To what extent is Canada responding to that summit, and to what extent have we been leading the way, working with, for example, your office and your country?
