I did two tours of AVCON as a brand new subbie and there isn't a better job to teach leadership to a young officer then sending them up into the mountains on their own with a gun detachment. It gives you everything - equipment maintenance, personnel problems, maintenance of morale during slack periods, hot and heavy operational firing that can last for days on end and expend hundreds of rounds, dealing with other government departments.
It's also fun and challenging for the troops.
I guess having working guns is an issue...
The 105mm might be a problem, as well as generating gun dets for that duty while also converting Reg and Res Arty units to other weapons in that period.
There are and will be enough guns. Assuming that the 105mm calibre will go out of service as a training gun as planned, then there will be enough serviceable parts available for a long time yet. Ceremonial salute guns need very few replacement parts and can be sources. The AVCON guns have been slightly modified for their role but those mods can be transferred to a replacement gun.
Honestly, Parks Canada has had almost 60 years to figure this out. Almost everywhere else in the world Parks or highways staff do this job.
I don't know what the financial arrangement between Parks Canada and DND are, but a 24/7 on call staff for 26 weeks of the year will be very pricey. Far pricier than an eight-person army detachment.
Also a tech issue, they have been trying for years for calgary class A techs to take over maintenance on those C3s. The problem? Every C3 maintenance course the past 8 years has been cancelled, and this year just did too. Currently that course only ran twice since first created, creating only around 8 techs nationally in the class A world.
That's a very real problem but easily cured if a course is run while the gun is still in general service. 1 CAB will be in Edmonton and is supposed to get a service battalion. Build it into the plan while you can.
I look forward to the C3 retiring and a M777 starts being used.......
The plan is for the M777s to probably go into long-term storage once enough SPs come on line. Based on the way the army usually does these things the skill set for maintaining M777s will deteriorate the same way as it did for the M109s. (I guess we could always contract it out to 10 Mountain in Fort Drum.

)
I'll inject an idea here.
Why not grab some drones with the ability to drop HE and use those to deliver the charges?
Happening daily in Ukraine....maybe the CAF could use this as a testing ground.
About half the shoots done up there are "storm shoots" which would make flying drones (or other aircraft) at those elevations nigh unto impossible. There are places where avalanche control is done by dropping dynamite out of helicopters but not where keeping the major east-west highway and railway link through the mountains open. That can be done through quieter periods like the "clean up shoots" done at Rogers once the storms have passed.
My short $0.02. The CAF keeps going on and on about being seen to be relevant to the nation not just in time of war but also to provide certain military skill sets that are of value to the country in peacetime, be it flood control, fire fighting, urban rescue etc. AVCON is probably the prime example of this type of service. For half the year the army helps to keep commerce flowing across the mountains. I've seen avalanches there. If you don't bring them down while small, they will cover the highway or railroad to a point where it could take up to a week of heavy machinery to dig it out. Sure. You could tell Parks to come up with a solution but let's be honest - we can always get Class Bs for this and even a RegF lieutenant and sergeant for half a year. Make it a 2 Div duty tied in with 1 CAB. AVCON is worth the effort and pays dividends when the MND needs another minister's support in cabinet. August of 2027 is too tight of a timeline in any event. This is either a cop out or DND is angling for a better MOU. I fear DND isn't smart enough for the latter - it's just someone trying to shake off a very tiny maintenance and personnel burden.
