George Wallace said:
Reserves are 'voluntary', period. The Reserves are NOT 'involuntarily' sent on foreign, nor domestic, deployments. All Reservists who deployed to Afghanistan, or any other foreign deployment, have done so voluntarily.
It would take an Act of Parliament to 'activate' Reserve units in times of 'Total War', such as WW II, for deployment outside of Canada.
Wrong! Wrong! and indirectly, partially right.
The National Defence Act has several key sections that provide for the terms of service for reservists which DO include obligatory service.
S 31 allows the Governor in Council (i.e. cabinet) to place individuals and units (including reservists) on Active Service for the defence of Canada or in support of UN or NATO obligations;
S 33(2)(a) and QR&O 9.04(2) provide for those circumstances where reservists and their units may be ordered to train;
S 33(2)(b) allows the GiC to call out reservists and their units to provide any lawful duty other than training and make regulations to that effect. QR&O 9.04(3) is such a regulation that provides that the Minister of Defence may do so in the event of an emergency which is defined to include war, invasion, riot or insurrection whether real or apprehended;
S 275 provides that the CF (including reservists or units) may be called out for service in aid of the civil power
All of these are provisions already enacted in the NDA and may be triggered by the GiC or the Minister as set out in the individual sections. All of these are obligatory service and NOT voluntary.
That said, the practice at least since Korea, or even earlier has been NOT to use these provisions but to rely on reservists individually volunteering their service.
The point is however that a common practice, even a long standing one, can be changed at the drop of the hat with the right Minister, cabinet and situation without the need for any action by parliament at all.
Don't let the above worry you as far as joining the reserves and the police at the same time. The chances are extremely slim that you will be required to do anything other than "voluntary" service.
