Narrative:
Had pilot bulletin about cyyc egpws unreliable on some aircraft. VMC clear. Got a too low terrain warning on short final approach approximately 50-75 ft. AGL to runway 35R. ATIS report was 40 mile vis. Clear skies. First officer was hand flying; captain monitoring pilot. Instead of reaching over the throttle quadrant and flap lever to inhibit terrain possibly causing a subsequent abnormal situation; knowing that the landing is safe; I opted of having first officer land the aircraft.
