Hard-sided, non see-through, locked case that cannot be easily broken into during transport

The website specifies a hard-sided, non-see-through, locked case that cannot be easily broken into. The tariff requires only that the firearm be "suitably packed", with no rigidity, opacity, or lock specification at all. Not resolved here.

Follow the stricter of the two. Meeting the tougher requirement satisfies both, and the contract of carriage is what the airline can enforce at the counter.

Firearm must be unloaded at check-in AND secure and trigger locked, in addition to the locked hard-sided case - a dual requirement (trigger lock on the firearm itself, plus a separately locked case) with no stated exception for ordinary hunting rifles/shotguns, unlike Porter's and Air Transat's non-restricted carve-outs. The tariff states only that the firearm must be unloaded with the safety catch "on" - no trigger lock or locked case requirement at all. See conflicts.

The website requires the firearm to be unloaded AND trigger-locked AND placed in a locked hard-sided case - three layered requirements with no exception for ordinary hunting rifles/shotguns. The domestic tariff's baggage-acceptance clause requires only that the firearm be unloaded with the safety catch in the "on" position and "suitably packed" - it says nothing about a trigger lock or a locked case. Not resolved here.

Follow the stricter of the two. Meeting the tougher requirement satisfies both, and the contract of carriage is what the airline can enforce at the counter.

Only shells or cartridges are acceptable; gunpowder and gunpowder pellets are strictly prohibited. No specific weight limit (e.g. 5 kg) is published on the website, unlike four of the five Tier 1 carriers. The tariff states only that ammunition carriage "is subject to the ICAO and IATA regulations", without a stated quantity.

The website gives a type restriction (shells or cartridges only; gunpowder and gunpowder pellets strictly prohibited) with no stated quantity limit. The tariff gives no independent quantity or type rule at all, deferring entirely to "the ICAO and IATA regulations" without naming a specific division or weight figure (contrast Air North, whose tariff and website both name IATA Division 1.4S and a 5 kg cap explicitly). A traveller cannot determine a specific weight limit from either Canadian North source. Not resolved here.
