I can talk about some of that.
I think GeoExchange is a great Canadian success story that's been undersold. It brings kudos to NRCan and some of the work of this committee, because it's been low cost.
One of the things we're facing right now is that it's very hard for us to reach municipalities. Denis was talking earlier about how it's easy for a municipality to outlaw something that's been permitted at either the federal or provincial level. So there's a lack of that type of coordination.
I think there's also a great opportunity for the federal government to work with other governments in providing a moral or financial example. Very often GeoExchange makes financial sense, and that's why our industry has been growing at over 100%. But we'd rather talk about integration with other technologies and how that makes sense for everyone on the demand side.
