Very restrained answer there
@armoured. I wish I could show your reserve. Me, I feel like shouting ARE YOU NUTS? Does the OP really think they can tell the IRCC what they are prepared to do and what they are not prepared to do, including refusing DNA request, and then the IRCC will come back with "Okay, sorry, just thought we'd ask."? I would hope (and expect) the IRCC to fast track the application into the trash can.
