CAR 166A:
(f) subject to subregulation (4), if the pilot takes off from the aerodrome, the pilot must maintain the same track from the take‑off until the aircraft is 500 feet above the terrain;
No mention of 100', 200', or 700'. (Subregulation (4) is an exception if a turn is necessary to avoid terrain.)
Nothing to do with the accident at the centre of this thread though - just clarifying the current legal (normal ops) standard.....
