This comes from some experience I've had working with Canada's largest architectural firm. They operate on a global basis. Having audited their projects on a global basis, I would point out that in the United Kingdom, the government there is mandating for new construction a certain level of building certification and a certain level of energy performance.
In terms of Canada's industry itself, again, I agree it's completely world class. But in Europe, what you tend to have is a government mandating a certain level of minimum performance that generates an industry.
