Reality is that nobody knows 100% what the new rules will be until they come out. For example the proposed rules for CEC applications was that the person had to still be in Canada but at the last moment before they published the rules for it, they changed it so that you can have left Canada already and can have been gone for up to one year and still can apply.
Right now we only have some proposed changes for the skilled worker program on the CIC website. If you were to look at that, you might think that some occupations will be fast forwarded but other people can still apply. Then we have snippets of rumours coming from meetings that the immigration minister had with other people saying that people not from the chosen occupations need not apply and even going as far as saying that the people from the chosen occupations might even need an AEO to apply so really nobody can say for sure what the new rules will be until they are posted. At this stage, it's all speculation.
