Sorry for jumping in again with some tangential context.
Playing with what CANADA means.
And where the Canadian Army fits in to the discussion.
WRT the discussion - My inclination is to have the Canadian Army focus exclusively on the immediate operational priorities as they apply to the three regular brigades and their support and how the will co-operate with CANSOFCOM, the RCN, the RCAF and the other less well known operational elements of DND.
Domestically there needs to be a continuing effort to join the operations of the RCMP, the Coast Guard, the SAR community, the Rangers, the Territorial Brigades, the Militia units located within the provinces and the Provincial Sheriffs and Constabularies. That is a separate discussion and requires a separate focus.
The third discussion is the active defence of Canada and national mobilization. That discusssion, I suggest, should be predicated on the RCAF and the RCA with involvement of the RCN. Those are the elements that have the bandwidth to manage the technicalities of defending against aerial bombardment - whether by means of Fractional Orbital Bombardment, ICBMS, stealth missiles launched from container ships or swarms or drones deployed by Hells Angels.
The Territorial Brigades, the Militia, the Areas, the Rangers and the Joint Task Forces will, of course, find gainful employment under those circumstances.
I am not sure that devising a National Defence plan predicated on recreating the Canadian Expeditionary Force for service in either Latvia or Taiwan is necessarily the best use of resources.
PS - the BCAD figures represent the Provincial and Territorial GDPs. Canada is assumed not to have a GDP beyond the sum total of all of its elements. On the other hand Canada does have a Budget.
