Frequently asked questions
What customs clearance options exist for arrivals at CYSB?
Sudbury Airport is designated as an Airport of Entry with a fifteen-person limit, referenced in the data as AOE/15. This means customs clearance is available on site, but only for aircraft carrying fifteen or fewer persons at a time. Flights exceeding that count need to make separate arrangements before arrival. Dispatchers planning larger group movements through CYSB should confirm passenger counts fall within this threshold ahead of filing.

A secondary runway, 12/30, offers 5,000 feet of length at the same 150-foot width, also asphalt. Both runways are paved, giving Sudbury Airport two usable strips oriented in different directions for crosswind flexibility. The 6,600-foot length on 04/22 accommodates most business jet categories operating into the region.
