Actually CAO 20.16.3 Part 4 plainly states that :
Except as provided in subsections 14 and 16 safety harnesses, or seat belts where safety harnesses are not fitted, shall be worn by all persons at the times listed in paragraph 3.1.
It doesn't differentiate between adults, children or infants except when the latter are carried in an infant seat or when children share a seat.
Subsections 14 and 16 refer to carriage of sick or injured persons and carriage of parachutists.
It simply says ALL persons must wear a seat belt or safety harness, regardless of whether they are in the lap of another passenger or on their own seat. The point to make I suppose is that if you are using the infant restraint belt that loops through the normal seat belt then the infant is technically using a safey harness as is different from a seat belt which indicates use of a seat.
Isn't the law fun!
