Incident at TORONTO / LESTER B. PEARSON INTL ON (CYYZ) (Conflict - potential, Conflict - loss of separation, Communication navigation surveillance/air traffic system, ATS operating irregularity)

UPDATE Supplemental information received from T.S.B. Initial Notification [#A08O0055]: The Air Canada Airbus A-320-211 aircraft (operating as flight ACA1224) received a departure clearance and advised that the clearance the aircraft would be flying would be a VNAP A route. The flight strip did not get marked with the required information and the South Tower Controller was not provided with this information during the departure operations. ACA1224 was cleared to FL070 on initial contact by the Departure Controller. American Eagle flight EGF4539 was the next departure and was cleared to FL050. The Departure Controller recognized that separation would be reduced below requirements and held EGF4539 at FL040 until ACA1224 had left FL050. Separation between the two aircraft was reduced to 2.6 miles laterally and 1,000 feet vertically. The required separation within this airspace is 3 miles lateral and 1,000 feet vertical.
The Air Canada Airbus A-320 aircraft (operating as flight ACA1224) was departing on a scheduled IFR flight from Toronto (LBPIA) (CYYZ) to Orlando International Airport, FL (U.S.A.) (KMCO). The AMR American Eagle, Inc. (Dallas/Ft. Worth, TX) Embraer EMB-135 Regional Jet aircraft (operating as flight EGF4539) was departing on a scheduled IFR flight from Toronto (LBPIA) (CYYZ) to Boston (General Edward Lawrence Logan) International Airport, MA (U.S.A.) (KBOS). ACA1224 received their departure clearance and advised Clearance Delivery that they would fly a VNAP "A" departure. However, the strip did not get marked as such and the South Tower Controller did not have this information during departure operations. Subsequently, ACA1224 was cleared to 7,000 feet on initial contact by the Departure Controller. American Eagle Airlines flight EGF4539 departed next, cleared to 5,000 feet. The Departure Controller stopped EGF4539 at 4,000 feet until ACA1224 commenced the turn and/or left 5,000 feet. The vertical separation was not less than 1,000 feet but the lateral spacing was 2.6 miles due to ACA1224's initial slower ground speed. Ops. impact -- unknown.
