It's actually a very valid point. At this point the national building code, the national energy codes, apply to new buildings. What the National Research Council is doing is creating what we consider to be a technical guide. It's a technical guide because there's currently no code for existing buildings. That technical guide will be written in code language so that the provinces can say, “Okay, we want to take this technical guide and either enforce it immediately, phase it in, or through any major retrofit or renovation, we will force the homeowner or the building owner to meet these certain requirements.” They could meet some of those requirements through grants, or they could say, “You're coming in for a retrofit of your house and you're renovating 40% of your home. We're going to trigger a mechanism that you have to upgrade your insulation, your windows, your doors.” It will be up to each province to decide how they're going to incorporate that.
