Hello,
According to my research, Its not much difficult to get registration only but you have to pass the licensure exam and French language test too within 2-3 yeras for getting full permit. but once the registration process complete you can work as a CPN (Candidate for professional nursing). AT first, all you have to do is to ask OIIQ for registration package ,and you can ask now for that..they will send the package in your email .Then you have to pay the fee and get a file number . after you get file number you have to fill the other forms from your educational institution and current/previous employer. I think they will ask for some integration program if they feel we are not competent and after completing some bridging program we can work as a CPN . i hope this will be useful for you.

, By the way have you started the federal part already?
I had a link but i couldn't upload here ...you can search for OIIQ registration for overseas nursing...gud luck
