When ready for takeoff, the pilot shall request a takeoff clearance and should include the runway number.  Upon receipt of the takeoff clearance, the pilot shall acknowledge and takeoff without delay, or inform ATC if unable to do so.  Pilot:   WINNIPEG TOWER, CESSNA GOLF BRAVO MIKE DELTA READY FOR TAKEOFF, RUNWAY THREE SIX.  Tower:  BRAVO MIKE DELTA, WINNIPEG TOWER (any special information- hazards, obstructions, turn after takeoff, wind information if required, etc.), CLEARED FOR TAKEOFF, RUNWAY THREE SIX.  Pilot:  BRAVO MIKE DELTA.  A pilot may request to use the full length of the runway for takeoff at any time.  If the runway is to be entered at an intersection so that back tracking is required, the pilot shall indicate his/her intentions and obtain a clearance for the manoeuvre before entering the runway.  A pilot may request, or the controller may suggest, takeoff using only part of a runway.  A pilot's request will be approved provided noise abatement procedures, traffic and other conditions permit.  If suggested by the controller, the available length of the runway will be stated.  It is the pilot's responsibility to ensure that the portion of the runway to be used will be adequate for the takeoff run.  To expedite movement of airport traffic and achieve spacing between arriving and departing aircraft, takeoff clearance may include the word "immediate".  In such cases, "immediate" is used for the purpose of air traffic separation.  On acceptance of the clearance, the aircraft shall taxi onto the runway and takeoff in on continuous movement.  If, in the pilot's opinion, compliance would adversely affect his/her operation, the pilot should refuse the clearance.  Pilots planning a static takeoff (i.e., a full stop in "position" on the runway) or a delay in takeoff shall indicate this when requesting takeoff clearance.  A controller may not issue a clearance which would result in a deviation from established noise abatement procedures or wake turbulence separation minima.
