I can answer that, given that my team has been overseeing it.
We did put a significant amount of work into this over the past year. We issued a directive on accounting standards to guide departments. We've provided them with information on how to code their transactions. We've worked with our IT folks to build in the information to allow departments to track it.
Probably most importantly, we've had working-level meetings as well as meetings at the director-general level to bring all the implicated departments together so that they can work together. They can share what one is learning from the other and the resources they're using for how to tackle some of the challenges.
Through that, we've issued questions and answers to some of the frequently asked questions and issues that have come up. There has been an awful lot of collaboration across the government to give the departments the information they need to improve their estimates.
It's hard. There's a lot of old information. We have historic sites. I met with my provincial colleagues last week. They have all the same issues. We have buildings that are hundreds of years old. Floor plans may not exist. Work needs to be done.
I know that national defence is currently in the process of bringing in.... I forget the word, but there's a technology that does an electronic floor plate to determine the square footage. On blueprints that are 50 or 60 years old, they found they couldn't even read the numbers anymore.
Trying to get the completeness and accuracy on old, historic sites is a challenge. That's the type of work and refinement that will need to happen.
We will continue to look. Specific to asbestos, if there are differences in rates, do they make sense or not? There might be a difference in cost between downtown Toronto and Nunavut. They might need to be consistent or there might be reasons that they're different. That's one of the things we'll do with our working groups this year.
