The sad truth is that we won't know until we see it happening. It was the same with the introduction of the LMIA last June. The said that all applications as of June 22nd are affected and what happened? They refused all LMO applications still being in process. My LMO application was filed on June 9th and returned on August 13th as refused due to the recent changes of the regulations, even though our HR office called CIC before and they told them that my application would not be affected.
The thing with CIC is - they do whatever they want. They adjust and change the rules to their convenience at all times. By saying "applies to all applications as of January 26, 2015" it could either mean "applies to all applications submitted after January 26, 2015" or "applies to all applications, including those still being in process, as of January 26, 2015". Is that done purposely? Of course it is. By using this sort of broad phrasing they are keeping their options open. Like I said, it was the VERY same thing with the change from the LMO to the LMIA. I know this is not what you want to hear (trust me, I've been there) but at this point, all you can do is wait and hope.
