It's a complex subject, there's absolutely no doubt. As I've said, the portfolio of our infrastructure is worth about $26 billion. Certainly, we don't have the kind of money we need to maintain to the standard that we should a portfolio that large. We will continue to try to focus on ensuring that heritage buildings are conserved and maintained, but our priorities will always be health and safety and compliance and operations, as we said.
I will note that, over the last three years, we have spent $220 million on maintaining specific heritage buildings that have come up in the list: Halifax North Park Armoury, the Wolseley Barracks in London and Admiralty House at the Naval Museum in Halifax. We are investing in heritage buildings, and all of these buildings we're investing in are in active use. Of the entire portfolio, only 3% of buildings, including heritage buildings, aren't being used. We invest in an armoury, and we invest in a runway, and it's where it comes up in the priority.
