Trenton/Mountain View Airport, (TC LID: CPZ3), is located 5.2 nautical miles (9.6 km; 6.0 mi) southeast of Mountain View, Ontario, Canada.
The airport serves as an Royal Canadian Air Cadets flying centre from May until October and as a flight training centre from June until the end of August each summer. Stored at Canadian Forces Detachment Mountain View, a geographically separated detachment of CFB Trenton located at the airport, are retired Canadian Forces aircraft including the CT-114 Tutor (Canadair CL-41) and CT-133 Silver Star (T-33 Shooting Star), CF-116 Freedom Fighter (Canadair CF-5) and CH-136 Kiowa (OH-58). The latter two in smaller numbers.
A new gravel runway was constructed in 2006 to train Canadian Forces CC-130 Hercules aircraft crew in landing on unprepared landing strips. The Canadian Forces have also established a drop zone nearby.
