I am not sure how YYZ does it, but I remember YVR once accepted my bag 7 hours before departure and I didn't lose it.
I'll do you one better: Aeroplan ticket, checked my bag in HKG at the airport express train station downtown, it went from downtown HKG to the airport, to ICN, stayed in ICN 23 hours, then ICN to FRA before I saw it again, and amazingly it was the first bag on the carousel. Something like 48 hours out of my possession and it survived! I will die before Canadian airports and airlines are able to pull that off (and before Canada/US allow bags to be kept overnight).
