Leoundesilva, I'm not entirely sure if you will need fingerprints if you submitted your file before the fingerprints for your country were put into effect. If I were in your situation, I would be proactive about it and send them in anyway in anticipation that they may ask.
If they do require them, it will help to keep your application moving if they have them before hand.
You can also call CIC and ask the same question, they may be able to look and see if there are any notes on your file indication that the VO will be asking for fingerprints.
EDIT: Congrats, folks-g!
