Reason for canceling IFR is optionally up to the pilot.
ATC will probably ask, "okay, radar service terminated, squawk VFR, what are your intentions?"
Actually, ATC could care less, as long as you avoid his/her other IFR traffic.
As soon as you cancel, he/she is finished providing IFR seperation services (less required work for him/her).
IOW, you are then, on your own. Just maintain appropriate VFR altitude.
