I can take a crack at it.
The testimony you've had to date has been pretty definitive in suggesting that the way the large-emitter trading systems in Canada work, including the OBPS, effectively shields businesses from competitiveness impacts and the risk of carbon leakage. I'm repeating what's already been told to you in committee. Firms only pay above the sectoral standard that's been set for them. Below that, there are no emissions. In fact, firms that beat the average sectoral emissions make money off it. There is incentive to improve, and there are sticks for those that don't.
Come on. Let's be real and fact-based. The average cost of carbon is quite low for these firms. That's deliberate. It's a mechanism for protecting these firms from competitiveness impacts.
