If you have cancelled ifr you must ask for go around instructions from the tower.
Well, I don't see any reason why one should ask those instructions from the tower. Just check VFR landing charts and join the correct traffic pattern and next report downwind or whatever necessary. In case if there are both left and right hand side traffic patterns for the particular runway then it would of course be the left circuit unless otherwise instructed by ATC.
