The aircraft has just arrived at the gate (nice view from the temporary international YUL lounge), and I can confirm that it is fin 740 and C-FIVQ. The fin (S/N) data on FlightRadar24 is incorrect.
No, it's not incorrect. S/N is Boeing's manufacturing number for the aircraft, fin numbers are AC internal fleet identification numbers. They're different.
