The collection features operational or restored vehicles, such as vintage tanks like Sherman Mark IV, Chaffee, M60, and Sheridan, as well as armored personnel carriers, trucks, and jeeps.

Additionally, the museum generates operating funds by allowing select Canadian and international television or film productions to use some of its vehicles.

Many vehicles, including the vintage Sherman Mark IV, Chaffee, M60 and Sheridan tanks, armored personnel carriers, trucks and jeeps, are frequently driven in parades and other ceremonial activities involving the Ontario Regiment or other units of the CAF.

The funding required to restore, maintain, and fuel the museum's historic vehicle collection and static displays is provided entirely by volunteers—current and former members of the Canadian Forces, veterans, cadets and civilians.

Aside from fully restored Bren Gun Carrier and M24 Chaffee, a pair of M4A2(76)W HVSS, and one unrestored Centurion, there are also a number of foreign-operated vehicles including a Scania HLVW prototype.
