There is actually a company based in Ontario, Conserval Engineering, that produces a product called the Solarwall. There are products that are available and actually manufactured in Canada that do heating through solar thermal. A lot of it, though, tends to be based in the manufacturing facilities because they don't use a lot of windows. So the solar wall or thermal heating for air works very well when you have a very large wall that's exposed to sunshine. If it's broken up by windows it makes it a lot harder to obviously implement that type of product.
There is Canadian technology available. Their focus is large walls and their focus is new buildings.
