Looking at departures from EWR and LGA in to YYZ, EWR's seem to be greatly delayed more so than from LGA.

I can see taking the Robert Q from London to Pearson airport as an alternative, but how does one plan for a return to London on the RQ if arrivals in to Pearson are so unpredictable? (rhetorical question)

For upcoming flights not already booked, DTW via the RQ is looking like a good alternative to those from London. Yes a 3.5 hr shuttle-bus each way, but at least you "get there."
