That's a great suggestion, and if I can do something analogous in the area of greening, certainly the federal government and PSPC—given it has roughly 6.1 million metres squared of office space—can influence the leasing environment to be more sustainable and green by putting different clauses into our leasing contracts that encourage or give favour to landowners and lessees who are supporting sustainment and greening. We're definitely looking at that, so I don't understand why we couldn't look at clauses in and around heritage as well.
