We have managed to keep the costs in line with those of traditional materials while implementing these new technologies. That's our edge; that's our difference from many other companies on a global scale. We have an integrated factory to fully automate and integrate—a factory that we have in Etobicoke. We produce everything locally here.
The way we have managed to create a business model is with the power purchase agreement as well as the direct purchase agreement. The builders or the building owners are basically not spending a dollar more, but are receiving renewable energy. That's part of our business model, to transform the old building as well as the new buildings that are being built in Canada.
