I initially selected all provinces as well. But then I was compelled to choose only one as a preference in the final PR form - and in an impulsive moment (not thinking it meant anything at all for the application), I selected Quebec. Eventually I wasn't even sure that I had selected it - I think I spent to long making sure all my other paperwork, my three PCCs, travel and address history, etc. etc. were accurate and put together. I am just really disappointed in this and quite shocked.
