What you were meant to do was this.... Before you signed the application for nova scotia you should have photocopied it. After photocopying the application sign original and send to nova scotia. That way you would've had a photocopy of the application with a nice big empty signature space to sign now. Simple mistake, just sign it and indicate one is CIO submission. I'm sure they'll figure out which one unless you posess the ability to manipulate the space time continuum. Only joking
