The canards on most of Rutan's designs are fairly highly loaded. Catbird seems to have been the exception. In fact, the story goes that many years ago one side of the canard was damaged at an airshow and they just cut it off and flew the airplane home without it. I believe it actually flew with "half a canard" for some significant amount of time. The (rear) horizontal tail contained the primary pitch controls (elevators) and were also the pitch trimming surfaces. As far as I know, the canards on Catbird had no movable parts or surfaces at all.
