For all those who missed the YYZ FT DO back in June, we did cover this EXACT topic and had some interesting discussions (especially from some very seasoned fliers).

Oh and btw the consensus was that connecting pax have priority. Just like connecting pax will be accommodated during IRROPS leading to hotel/food vouchers, while point of origin pax will not.
