I Invented a 2030s Civil Defence Guard. Canada Is Already Thinking Along Similar Lines

One of the problems I had to solve in Invasion is pretty obvious: Canada has a population of 40 million, but despite recent recruiting efforts by the Canadian Armed Forces, only a tiny fraction ever serve in the CAF. Even a substantially expanded force would still be tiny compared to the numbers the U.S. could field.

It's the same kind of problem nations like Switzerland and the Baltic states face, and the answer can't be a much bigger army because eventually, reality starts to get in the way

So, I imagined a Canada that had adopted something closer to the 'whole-nation defence' policies those countries have adopted: a system where national defence isn't just down to the armed forces.

But what would that look like?

The first part of the puzzle was obvious: if you're a government planning to fight a war against a massive enemy, you start by introducing national service.

The second was less obvious but had historical precedents: the National Civil Defence Guard (NCDG, or simply, 'the Guard').

National service doesn't necessarily mean bearing arms

In the world of Invasion, Canada introduces national service in the early 2030s. But the approach wouldn't just be 'here's a gun, now stand to attention and get your hair cut.' Instead, while some people would serve in the CAF, others would take civilian routes: civil defence, emergency response and other roles that keep society running under pressure. The key idea is that national service should leave people with useful skills, and an understanding of what would be expected of them in a crisis.

(Side note: my family was Spanish, even though I was born in the UK. In the 1980s and 90s, Spain had transitioned 'la mili' - compulsory military service - into a scheme that allowed people to serve as civilian ambulance drivers, firefighters, coastguards, etc. if they didn't want to join the forces.)

Ultimately, modern defence is about a lot more than handing everyone a rifle and telling them to "wait 'til you see the whites of their eyes." Someone has to keep communications running. Someone has to move supplies. Someone has to maintain critical infrastructure, treat casualties, coordinate evacuations, and respond when the power goes out.

That was the broad philosophy that I borrowed for my fictional Canada.

So, what comes next?

National service creates another problem, however.

Suppose someone serves in the CAF.

You, the government, spend time, money, and resources training them. They have combat skills, they understand military procedures, and they can function as part of a unit.

And then their service ends.

So, do you just send them off with a cheery wave goodbye and hope they'll remember it all years later?

In the world of Canada at War, the answer is no. All those people you've trained in military national service go into the Guard: a large (and ever-expanding) pool of trained Canadians whose skills are maintained or even developed through ongoing training and who can be mobilized if (when) the country needs them.

The point isn't to have a massive standing army. Rather, it's to have hundreds of thousands of people who already know what they have to do if things go badly wrong.

National service creates the pool. The Guard preserves the skills. Periodic training keeps them useful. Civilian service creates corresponding capacity outside the military. By the time Canada needs that system, it isn't trying to recruit and train hundreds of thousands of people in the middle of a crisis.

They're already there.

Then reality started to look rather familiar

Canada actually already has a pool of former military personnel to be called up in an emergency. It's called the Supplementary Reserve. And in the Spring of 2026, something caught my eye: an announcement that proposals were being drawn up to dramatically expand the Supplementary Reserve, alongside an increase in the size of the Regular and Reserve forces.

The Supplementary Reserve is currently fewer than 5,000 people. The plan would expand that by a factor of sixty, to 300,000.

Three hundred thousand.

And what would those people do?

The plan proposes basic instruction focusing on practical civic readiness skills like first aid, driving utility/military vehicles, drone operation, and basic fieldcraft or small arms handling. Those with specialist skills would work in intelligence, communications, logistics, medical roles...

Sounds familiar?

Fiction, meet reality

When I created the Guard, I wasn't trying to predict a specific Canadian defence policy. I was trying to solve a worldbuilding problem.

What I find fascinating is that real Canadian defence planners now seem to be wrestling with a remarkably similar one.

My fictional answer was national service feeding into a permanent Civil Defence Guard, creating a large pool of people whose skills could be maintained until they were needed. The real-world proposal isn't the same thing. But expanding the Supplementary Reserve from fewer than 5,000 people towards 300,000, and giving those people practical civil and military preparedness training and roles, is starting to rhyme rather loudly with it.

Apparently, that's becoming something of a theme.
