It is solely up to the pilot in command as to which one to use, if not specifically mandated for that runway/airport.
From Transport Canada AIM: RAC
"NOTE: To assist in planning departure spacing, pilots intending to use NADP 1 at Canadian airports are to notify ATC Clearance Delivery or Ground Control. At airports where NADP 1 is the only procedure to follow, ATC does not need to be notified."
In addition, that warning is posted somewhere on most Canada Air Pilot departure noise abatement procedure plates.
I have never had any questioning about the use of NADP 1, (unless told to Tower for the first time at release for take-off!
). There is no pushback if you would prefer to fly one or the other procedure, it is merely to allow ATC to plan the flow of departures.
I feel that sometimes Jeppesen, being an american company, has very little finesse when it comes to non-American procedures.
