The reference to CAR100 leaves the ambiguity of class E VFR procedures. where CAR99a refers to obeying a direction in a declared broadcast zone. Not doing the CASAs work for them but would we have to comply moreso with 99a than 100?
CAR99a
(5) A pilot in command of an aircraft that is operating at an aerodrome or area designated under subregulation (1) must not contravene a direction that applies to that aerodrome or area.
