Whenever you evaluate a project in Canada, and whenever it goes to cabinet, there's usually a socio-economic lens that's put on almost every project that is brought forward. The whole purpose of the strategic environmental assessment tool is to include a third lens. I would argue that most projects are always looked at from a socio-economic perspective, but they don't usually include the third aspect, which is the environmental perspective.
If you're going to look from a sustainable development angle, you should be looking at social, economic, and environmental costs, and that was the whole point of bringing forward the strategic environmental assessment tool.
