Frequently asked questions
Does CYAM have customs available for arriving international flights?
Yes, Sault Ste Marie Airport is designated as an Airport of Entry with customs processing onsite. Operators arriving from the United States can clear customs directly at CYAM rather than diverting to another field. This AOE status is a significant operational advantage for business aviation crews working the Ontario-Michigan border region. Crews should still confirm current arrival procedures and any advance notice requirements with Canadian customs authorities before planning a border crossing into CYAM.
What runway options are available at Sault Ste Marie Airport?
Sault Ste Marie Airport operates two paved runways, both measuring 6,000 feet in length and 200 feet in width. Runway 04/22 and runway 12/30 both have asphalt surfaces, giving crews a crosswind option in a region known for variable winter weather. Both runways offer the same maximum paved length at the field, so runway selection at CYAM typically comes down to wind conditions rather than length constraints. This dual-runway layout supports a range of business jet and turboprop operations.
How much business aviation traffic does CYAM handle?
CYAM recorded 3,194 business aviation operations against a total of 9,701 annual operations in 2025, according to FAA TFMSC data, since the airport sits along the Canada-US border and this figure reflects cross-border traffic seen by the FAA rather than the airport's full activity. Monthly volumes ranged from 223 operations in low months to 362 in July. This places CYAM among tier-1 fields in Skystar's classification for traffic volume and documentation. Dispatchers planning cross-border movements through Sault Ste Marie should expect this seasonal pattern when scheduling.
What is winter weather like at Sault Ste Marie Airport?
Winter conditions at CYAM are a significant planning factor, with an average of 30.2 days below freezing in January and 29.0 such days in December. Snow accumulation of an inch or more occurs on average 6.0 days in January and 5.4 days in December. Temperatures moderate substantially by summer, with July averaging a high of 75.6°F and no days below freezing. Crews operating into CYAM between November and March should plan for sustained cold and periodic snow events affecting ground operations.
What other airports are near CYAM for alternate planning?

Sault Ste Marie Municipal / Sanderson Field lies 5.80 nautical miles to the east, and Chippewa County International is 14.04 nautical miles to the south across the US border. Bar River Airport is located 17.44 nautical miles east, while Mackinac County Airport and Mackinac Island Airport lie roughly 37 nautical miles to the south.
