Hello SDS
In FSW 2014, when your application has been returned by CIC , at that time your application got assigned UCI number, as most of the people who got their application back due to cap got UCI which means they have your details which you filled specifically in IMM008(generic application form).
Normally Nova Scotia request this form to provide them if you have already applied for FSW program and I am sure they asked you too.
So I would like to know in that form what province you chose in point 6.(Where do you intend to live in Canada?)
If your answer was ONTARIO, that means you need to justify your answer why did you chose that time Ontario and now why you want to settle in Nova Scotia.
Well In FSW 2013, and FSW 2014 I put ONTARIO in my application, plus I was working for a company which is Montreal , additionally my wife was in Ontario so nomination officer asked me the same question too. So be practical and reasonable while replying to the officer about your intention to settle in Nova Scotia.
They are very nice actually they seriously want to nominate you thats the reason they are asking more information so you just need to clear them that you actually want to settle in their province.
