I can speak to this as it relates to heavy emitters in Alberta's industrial heartland.
We have an output-based allocation system for carbon pricing, and the revenues collected from the heavy emitter's price on carbon is returned to industry by virtue of a number of programs through Emissions Reduction Alberta and Energy Efficiency Alberta, which help industry improve its energy efficiency and fund various types of technology pilot projects. Some of those projects have been funded in the heartland around partial upgrading of bitumen, for example, and various other types of initiatives. We think that's an incredibly successful system and should be replicated across Canada.
