For domainers it would represent a short-term gain with new buyers jumping in initially, then it would be a lot of long-term pain as the bloom would be off the rose pretty quick and .CA would become meaningless to Canadian business. It would soon get lost with all the other generic ccTLDs from the various banana republics who are looking for some quick money and don't care about the future.
Remember, Canada is an actual country with a business sector that needs their own ccTLD, not some island with a few thousand people on it (like .IO) or less than 1000 (.cc) who really don't give a crap about the future of their ccTLD. One some of these tiny island ccTLDs, a vote would be a show of hands.
Transforming .CA into a generic ccTLD would be a huge long-term mistake for our country and with the history .CA already has and the CIRA continues to develop, I really don't see it happening.
