Narrative:
Two Boeing 737-800 aircraft were involved in a collision on the ground at Toronto-Pearson International Airport, Canada.
WestJet flight WS2425, a Boeing 737-800 registered C-FDMB, landed on runway 24R at 17:39 hours local time following a flight from Cancún, Mexico. 
Preliminary reports suggest the aircraft was stationary on the taxiway near the gate when another Boeing 737-800 was being pushed back from gate A14 (Terminal 3). This aircraft (C-FPRP, operated by Sunwing Airlines) had arrived from Cancún Airport as flight WG272 and had parked at gate A14 at 16:38 hours.
During pushback the APU of C-FPRP impacted the wing tip of the WestJet aircraft. A fire broke out in the APU and the wingtip of WS2425 became engulfed in flames. The WestJet aircraft was subsequently evacuacted on the taxiway.
The APU fire was quickly contained.
