Case required Published
Locked hard-sided case (website); suitable hard-sided, opaque, heavy-duty container or case (tariff)
The tariff additionally specifies the case must be opaque and heavy-duty; the website only requires "locked hard-sided". Additive, not contradictory - see conflicts for the trigger-lock wording difference.
Air North, Yukon's Airline’s wording
The firearms must be in a locked hard-sided case.
Firearms must be rendered inoperable, such as with a trigger lock, and packed in a suitable hard-sided, opaque, heavy-duty container or case.
Locks required Sources disagree
Case must be locked (website). Tariff additionally requires the firearm itself be "rendered inoperable, such as with a trigger lock" in addition to the locked case - a stricter, dual requirement (locked case AND an inoperable firearm) not stated on the website for any firearm class, with no non-restricted exception published anywhere.
The website's dedicated firearms section requires only that the case be locked, with no mention of rendering the firearm itself inoperable. The tariff's Firearms and Ammunition rule (Rule 55(11)5) requires the firearm be "rendered inoperable, such as with a trigger lock" IN ADDITION to the locked hard-sided case. A separate catch-all tariff rule (Rule 55(F)5) states only that the "safety catch is in the 'on' position" is required - a third, even looser standard. Not resolved here.

Tariff (contract of carriage) Firearms must be rendered inoperable, such as with a trigger lock, and packed in a suitable hard-sided, opaque, heavy-duty container or case.
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.
How much ammunition Published
Up to 5 kg (11 lb) per passenger, Division 1.4S ammunition only (IATA Dangerous Goods Regulations). Ammunition not in Division 1.4S is not accepted as checked baggage. Ammunition over 5 kg must be shipped as Cargo.
Matches the 5 kg figure published by all five Tier 1 carriers except Flair. Air North is the only carrier found so far to name the IATA Division 1.4S classification explicitly on its public-facing website, not just in a tariff.
Air North, Yukon's Airline’s wording
Only ammunition in Division 1.4S , as defined in the IATA Dangerous Goods Regulations, weighing less than five (5) kg (11 lb) per passenger, will be accepted for carriage as checked baggage.
The ammunition may not exceed 5kg.
How to pack ammunition Published
Packed securely, preferably in the original container or a container specifically designed for small arms ammunition. Firearms and ammunition must be packed SEPARATELY - in separate checked baggage, per the tariff (stricter than "separate container, same bag").
The tariff clarifies "packed separately" means separate PIECES of checked baggage, like Air Transat and unlike WestJet/Porter which permit the same bag with separate containers. The website's "packed separately" alone is ambiguous; the tariff resolves it. This is additive clarification, not a conflict.
Air North, Yukon's Airline’s wording
The ammunition must be packed securely, preferably in the original container, or in a container specifically designed for the carriage of small arms ammunition.
The firearm and its ammunition must be packed in separate checked baggage.
