The Museum engages visitors with the wonder of flight through its spectacular collection, educational programming, activities, and special events. The Museum focuses on aviation in Canada, but within an international context, from its beginnings in 1909 to the present day. As Canadas contribution to aviation expanded to include aerospace technology, the Museums collection and mandate grew to include space flight.The Collection itself consists of more than 130 aircraft and artifacts (propellers, engines) from both civil and military service. It gives particular, but not exclusive, reference to Canadian achievements. The most extensive aviation collection in Canada, it is also considered one of the finest in the world.Care and development of this collection remains one of the Museums main purposes. The Museum practises conservation and restoration techniques to keep the collection in a condition equal to the highest standards.
