BPF:-
I would suggest that Canadian and British parents have similar levels of risk tolerance for the safety of their children. So why can't the British Air Cadets basically give any of their cadets a meaningful "air" experience when the Canadian Air cadet organization manages to give around 300 cadets a full Transport Canada Glider Pilot License every year ? The Canadian Air Cadet program also has a robust program of air experience flights in gliders for the younger air cadets.
As far as I know the Canadian Airworthiness Authorities have not deliberately subverted and suborned their own Airworthiness Regulations. The British Airworthiness Authority (aka the MOD and its wholly owned subsidiary the MAA) has, and maintains a continuing cover up of that illegal action, thus preventing reform. That is why, BPF, and will continue to remain why until Regulation and Investigation is removed from MOD control.
