Sorry for the late reply, I've been in Darwin. The original L10's covered YYZ to GLA, MAN, LAX, BGI and YHZ to LHR. The 500 series covered YYZ to ZRH, BOM and SIN and YVR to LHR. Flights from YYZ/YUL to LHR, CDG and FRA were covered by B747's. The DC8's (before conversion to freighters) covered all the other European routes until the B762ER's arrived in the fleet.
