The President and SoS are, of course, free to ignore this resolution should it pass. But I will have to go dig up the prior debate around the initial Canadian Common Market Agreement and see why it was dumped (or people who were around pre-reset could weigh in if they so choose).
It wasn't dumped. The ACCMA was in place until it was repealed by the reset; afterwards, people decided to pursue a deal with the UK because they asked first and it was more "novel" at the time as we'd had a deal with Canada for years.
