I am looking at booking YQR-CDG as a back up, possibly on the same days but more likely leaving and returning a day later as otherwise the YQR-YYZ and YYZ-YQR segments would be identical.
If there is a risk of cancellation I will book on AF, but I am not keen on having to do WS segments intra Canada, other than wanting the AE points in any case. The bookings are/would not be FP.
If the flight times overlap at all, I'd basically say there's a 99.9% chance one will be cancelled.
If they don't overlap, but they're impossible (i.e. you arrive in LHR 5 hours before your YQR-YYZ-CDG trip starts), there's still a pretty high chance.
And even if they're totally possible to fly, but "too close together", there's STILL a chance something will be cancelled.
