Few days ago, Canada's Immigration Minister replied to a twitter question about the list of occupations for the new Federal Skilled Worker program. Here's a screen shot of his answer:
It looks like there will be no "priority list" to be expected. According to Immigration Minister Jason Kenney, the new Skilled Worker Program will be limited to applicants in NOCs 0, A & B, but won't be limited to particular occupations.
This is an interesting development. It's like back to pre-February 27, 2008, only that there will definitely be a limit on the number of applications to be accepted. If the limit will only be say, 10,000 applications across all NOC's, it will most likely be filled within a week or two. The more reason you should start preparing your documents now!
