The Seniors of 94 Air Cadets play a vital role in the effective functioning of the squadron. Senior cadets are 15 years old and up, and are in a minimum of Proficiency Level 4. Their longstanding commitment to the cadet program is rewarded as they are given more responsibility and leadership roles, such as teaching classes, leading the Pipe and Drum Band, and the Drill Team.

All cadets give back to their community, by participating in Remembrance Day ceremonies, and other community service activities, including working with local veterans groups such as the Newmarket and Bradford branches of the Royal Canadian Legion. However, the Seniors also take part in the annual Remembrance Day Overnight Vigil at the Newmarket Cenotaph, and taking on supervisory roles with younger cadets at these and other activities.

To start off each training year, the Seniors of 94 Squadron meet for a full weekend to refresh their survival skills, set goals for the year, learn new instructional techniques, and have a bit of fun at the same time.
