Enough time to clear immigration, collect bags and recheck if everything is on schedule, not much time to spare if you have any delays or a long queue. If you have carry-on only, nexus and/or priority security it will be safer than without.

Bag drop at YYR closes at T-45m for a domestic flight so that's your cut-off if you have checked baggage. AC will interline the bags if both flights are on AC but not if OAL are involved.
