Ron R. - I'm having the same problem. I don't want to stop paying CPP but it seems that NO doesn't mean NO. I'm 67 employed, receiving CPP and self-employed and answer NO to all CPP questions in CONTROL but get a message in REVIEW that I have selected to stop paying CPC, etc.. Nowhere have I indicated that this is the case.
I don't have an answer and when I used Support Assistant I got a robotic reply with series of links which were useless. Hopefully someone from UFILE can resolve this. It looks like a glitch to me.
