You are not required to have signals. If you do then they must be in good repair and meet visibility requirements. It's not a good idea to go without them, though, as they provide better visibility and you would be required to hand signal all moves, without them, to people who probably no longer have any idea what the hand signals mean.
As to fenders....
Mudguards
(3) Every motor vehicle and every trailer shall be equipped with mudguards or fenders or other device adequate to reduce effectively the wheel spray or splash of water from the roadway to the rear thereof, unless adequate protection is afforded by the body of the motor vehicle or trailer or by a trailer drawn by the motor vehicle. R.S.O. 1990, c. H.8, s. 66 (3).
Translation: You require fenders.
