It will be really unfortunate if we cannot see the document before the election. I am not sure we can trust the government to give an honest assessment of it.
Although, reflecting on the limited number of campaign ads I've heard, this seems to be something that no one is really talking about.
I'll admit that I don't follow the leaders' discussions all that closely; most of my opinion on what's going on in this race has to do with the ads I've seen and heard, whether on CBC Radio, TV, or before watching Youtube videos.
My impression that there hasn't been much public discussion about it mostly comes from the fact that the only memorable place I've seen TPP mentioned has been on HN.
