At the risk of being too verbose, I had to drop my 2cents worth in as someone familiar with the political agendas at play

Unless this is very intelligently managed and tightly controlled it could get you far more bad PR and legal trouble than you want.
In the mind of todays crown effete there is an almost nonexistent line between the right to citizen's arrest and self defense [an individual right not a collective right] and criminal vigilante gangsterism of a redneck militia or reactionary vigilance committee, - both politically stigmatized and de facto outlawed in conventional jurisprudence. If the Crown acts as if your claim to citizen arrest, self defense, defense of private property and community defense is conventionally invalid or dormant under juridic credo, they will persecute and prosecute you even if you are demonstrably within statute right. It's bad to be lawfully correct when the crown is lawfully disingenuous, - more on this later.
Undertaking the creation of a civilian force of properly informed and trained auxiliary community law patrol force is a staggering organizational and PR job. It will take time, professional LEO input, intense legal training and volunteer screening for the right people. Most of all it will take open minded media cooperation to make the principles at play public knowledge without the usual political distortions.
I do not condemn the idea, I acknowledge Caledonia is in a state of protracted criminal blockade where the constitutionally appropriate rule of law was arbitrarily suspended and soft [race based] martial law invoked. However I question if this form of [lawful] citizen action has been well thought out. It’s one thing to stay within the narrow confines of CCC sections 38 - 42 defined by legal precedent, but as I said previously this may not be enough. You will be legally and civilly justified, even if you are likely to be illegally arrested or assaulted, but reclaiming your legal right to self defense and community security will be a long and costly process when the political-administrative winds blow against you..
.
My other worry is that CCC sections 38 - 42 wording provides for a force equals force test of what is reasonable force to stop a criminal act, apprehend a lawbreaker and hold them for, or deliver them into, police custody. Essentially, after you inform the suspect they are under citizen's arrest for breaching XYZ of the criminal code, you have, in pith and substance, all the powers of a peace officer [temporarily and only in the complete absence of police] to;
A) stop the criminal act and
B) to defend yourself from an attack or resistive violence of the suspect lawbreaker by any means equal to the force used against you..
You really have to be prepared to defend yourself against life threatening attack because that's what you face with these violence-threatening trespassing extremists. I prey you can control the situation and your force of citizen police well enough to not escalate the situation into a lethal situation. We don't need any more Sam Gualtieris or Dudley Georges for malpractice media, SN extortionists or reactionary thug-appeasing politicos to exploit.
Frankly. I think the whole ‘militia’ idea is doomed from the start PR-wise. By tagging it as a militia, you mobilize a political trigger word that has been stigmatized by the neurotic media as synonymous with anti-government extremism. As far as the establishment media and fabian political class are concerned you just handed them a club to kill your movement with. They'd demonize a principled citizen's empowerment movement in a heartbeat. The political stigmatizing sets up the justification for venal authority to deal harshly or illegally with any attempt at exercising citizen's arrest rights. It is hard to exercise a right which the powers that be have spent decades denying exists. You are exercising justified defensive force in lawful defense of yourself, your property, your neighbors, your community and the law when the state has propagated the idea that only they have a monopoly on the use of defensive force.
I cite as my argument the way Curtis Sliwa, respected founder of the Guardian Angels, was treated when Canadian communities asked him here to help set up one of his very successful citizen-run community crime patrols. Here’s a man who is beyond reproach as a community spirited anti crime activist, honored by presidents, mayors and community leaders alike for decades. He was savaged in the Canadian media and roundly demonized by Canadian statocrats, police brass as a “vigilante”. I was shocked at the vitriol heaped on Sliwa for volunteering his time to help empower Canadian citizens take their communities back from the effects of ineffective justice and police systems. Again, the idea that the Canadian police function and the state reserve a monopoly on the use of defensive force was front and center in al the anti community patrol rhetoric.
I say this not to be a doom sayer but only to caution you to one aspect in the political culture war that has raged in Canada's law and legal systems for decades. Influential Fabian statists have been propagating Kafka-esque myths for years to justify removing most traditional individual citizen empowerments and legal and civil freedoms. If you disbelieve me, try defending your property and family against an intruder or assailant with a firearm and watch the statist wigglers crawl out of the woodwork to make the victim [you] the criminal and the criminal who attacked you the victim. Most armed self defense cases are taken to trial by the crown. They become surreal Orwellian theater with traditional civil rights and freedoms clearly discounted by the state’s presumptive omnipotence over the individual. A complete reversal of our inherent classic liberal jurisprudence.
I agree that the CCC right to citizen's arrest and to self defense as well as jury oversight of judicial absolutism are the last remaining vestiges of our traditional civil rights. But be aware that these have been under sustained attack and manipulation at the highest levels for decades and are now heavily truncated in the justice system's operational mindset. Be aware of the waters upon which you intend to tread. There are some very powerful sharks swimming just below the surface.
Using the stigmatized militia label for lawful civilian-actuated civil defense is falling right into their trap.
