ZNA is a small downtown seaplane terminal (water aerodrome) with very limited amenities. No CATSA-style screening for typical seaplane departures, so security wait is effectively 0 minutes (check-in only). Minimum connection time set to 30 minutes given single small terminal/dock operations. Noise estimated as moderate due to proximity to floatplane engine run-ups/takeoffs but low passenger volumes. Natural light rated good due to waterfront terminal windows typical of Canadian seaplane facilities. Premium facilities (sleep pods, showers, spa, meditation, gym, lounges with beds, fast track) are not present at this tier. Healthy food options uncertain at the terminal itself; nearby downtown options exist but may be outside the facility. Estimates based on norms for Canadian tier-3 regional/water aerodromes.
