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.
Get involved, run for the board, initiate change
That's the only way it will change
Am I for it?
For me as a domainer - absolutely
Would it be good for .ca businesses - probably not
So you have to look at the core value of .ca and quite honestly it's not directed at us, it is to assure you're doing business with a Canadian entity and watering that down would water down the extension. It would make domainers and CIRA a pile of money but ultimately what good would it be visiting a .ca website doing commerce in USD instead of CAD?
There is this myth that only a Canadian citizen or permanent resident can buy a .ca domain. A lot of people probably don't know that foreign owned Canadian corporations can buy a .ca domain. If you have a registered trademark in Canada, you can buy a .ca domain name.
But only the EXACT MATCH to your primary trademark, effectively limiting a foreign entity to one .CA domain, or at best a couple.
I went through this with a CDRP I received from a foreign company and it's not like they can start registering .CA domain will-nilly, and nor can they mass register all domains with their TM in them. There are definite limits imposed by the CIRA and these applications require stacks of paperwork just to get one domain registered - in my case, we resolved the complaint but it still took 3-4 months for the CIRA to finally accept the TM paperwork and contact info for that one domain transfer.
As for the rest, let's just agree to disagree as you seem to be extremely aggressive in promoting a "Dot-CA for the world" agenda, so further debate would be unproductive.
I see a lot of people from India with registered .ca's, in fact the last 3 I bought the domainers that owned them were all from India. They totally ignored the Canadian restrictions. I wanted the domains so reporting them would have been unproductive and even so I tend to mind my own business so that was never an option.
