ESP must be left in the on position for CC to work. Disabling the ESP on Canadian vehicles also disables the cruise control.
I have also had the situation where my brake light switch was faulty and the brakes were on constantly to which I was not aware. I had booked in my vehicle for service on the no functioning Cruise Control when someone pointed out that my brake lights would not turn off. So of course that was the reason why the cruise control would not set.
