There are probably two big challenges, which I highlighted in my initial statement. One is the adoption by industry. The Canadian oil sands industry over the past decade has been not as forthcoming when it comes to innovation and deploying new technology. Part of it is that they've gone into an environment where the regulation has evolved. They've been thinking about where to spend investment dollars. I'd say there is an industrial side of things.
On the incentives, I believe, again, there have been some changes in regulation, including with the carbon tax regime. That has evolved over the last couple of weeks. We've had a new announcement with Alberta. That's now provided a bit more direction in terms of where things are going. the stability of the investment environment, first and foremost, will be important for the oil sands to implement these technologies.
