Heating the canister.
Reason: the canister is rigid (V constant), so from PV = nRT pressure is proportional to temperature. Both the temperature (–5°C → 0°C) and the pressure (713 mmHg → 760 mmHg) must increase to reach STP, and heating raises both. (Adding gas would raise P but not T; removing gas or moving to a larger canister would lower P.)
