The Canadians use very simple metal (strutted) gliders but i am not sure if they are available any more.
The Canadian gliders are SGS-233A's There are no cadet owned powered aircraft except the towplanes. The tow planes are L-19's, Belanca Scouts or C182's. Some areas also winch or auto tow.
The aircraft are civilian owned and registered by the Air Cadet League of the provinces. The aircraft are operated by the military to civilian standards, unless there is a more restrictive military standard. All pilots operate on their civilian licences.
The cadets all should receive 1 air experience in the glider every year. Powered Fam Flying is also done locally by the squadrons at their expense in locally sourced aircraft.
Cadets can receive their full civilian glider licence at a 6 week summer training course.
A 7 week summer training course to PPL standard is contracted out civilian flight schools
