Thanks, now I got it to show what I wanted to see.

Considering to make this a quick turnaround in YYZ, is there any feasible options for this? I can find some connections from EU to YYZ via JFK, however I am not sure if these would be same plane turnarounds or not, not familiar with these North American connections I'm afraid.

The other option would be the LHR route with BA, although this would probably necessitate a stayover in YYZ both directions (too risky connection?)
