If I may add, it depends exactly on which market or which sector we're looking at. We're intervening mostly in the commercial, industrial, institutional sector, but less industrial, because when companies have processes, it's kind of tricky to play into their processes.
If you look at the residential market, my personal belief is that, technology-wise, heat pumps, air source heat pumps, not necessarily ground-source heat pumps, will pave the way. I don't understand why NRCan hasn't come up with anything yet at this stage. Heat pumps would be a big asset.
