My vote is to put 44 tanks (three 14-tank squadrons) into Latvia and do a three year posting for a regimental headquarters, a full squadron and enough maintainers.
Another regimental headquarters and three tank squadrons go to Edmonton together with all remaining tanks (and I mean all! - except the RCEME reference tank). This regiment has a flyover task to round out the regiment with two squadrons and the rest of the regimental headquarters. They do level 1 to 4 in Canada and conduct at least two level 5-7 exercises in Latvia annually for three to 4 weeks at a pop. You can fly the whole shebang over in one CC330-Huskey for those folks still concerned about logistics. There's probably enough space to add a flyover rifle company to make a really good Battle group.
Easy-peasy. We supply a full tank regiment to NATO for three years. Logistics are simplified. No messy MRP or six month rotations to worry about. No burn out. Every three years you do another posting cycle for volunteers who want it.
Hell - add in a couple of two week level 3 and 4 summer exercises and you can have the KOCR and the SALH (maybe even the SaskDs) get involved as well.
I don't see the problem here. We have the tanks. We have eager people. We have a viable mission. This isn't rocket science. Move a little funding into tank maintenance and Bob's your uncle. And don't start with every regiment needs a turn. Sometimes you just have to tell people to FO. Throw them a bone and make a flyover recce/cavalry task as well.
