After a bit of thought, here's what I will do.

Once a legal action begins to roll, I will keep everyone here in the loop. Personally I would not hesitate to interfere; certainly our opponents have had no aversion to getting help from "progressive" groups in the US and much of the Canadian political battleground is littered with money from NY and CA.
I think probably the most efficient use of funds will be to put them directly into legal battles so for anyone who is interested, that's probably the route I would go and I will keep you all posted on how that looks to be developing. Conceivably there will be some entertainment value, at least, in screwing with Canadian progressives and the fact is that even a tiny fraction of US discretionary pro-gun donations would completely alter the balance of power here; there is just not the same kind of politics here and the money changing hands here is peanuts compared to what you are used to.
I may attempt to position the Canadian gun cause as a humourous mascot on some US forums for this reason. Just thinking about the numbers, I'd say if every American with an AR and a sense of humour threw in a buck, that would probably generate more funds than if every Canadian with an AR, with or without a sense of humour, put in a hundred. And that's before the exchange rate.
Of course that's hardly anything I would expect to happen but you never know; sometimes it's easier to motivate people to engage in weird jokes than in practical self-preservation.
Regardless, I'll keep everyone informed as things develop. I would say that for the moment, the strategy is "delay, deny, defeat in court" combined with "replace the government". Fortunately the current government is fairly weak, but unfortunately the opposition (which is moderately supportive of gun owners) is also fairly weak. The Trudeau Liberals are being propped up by three other parties which are pretty anti-gun, and they may or may not take issue with the way this was done, even though it's a pretty appalling abuse of process.
The only real solution is to bring down the government but that won't happen until the opposition is quite a bit stronger. Hopefully under two years.
At any rate I have no intention of relinquishing anything, not one grain of powder. Not even one New Brunswick locksmith, who was also made a prohibited firearm in this absurdly sloppy legislation. Thankfully he has not be used to shoot anyone yet but I don't think that's directly the result of this regulatory change: to my knowledge, nobody in the country had shot anyone with him before he was a prohibited weapon either. But now, not only can he not be used, even at a range, he also cannot be transported, bought, sold, or exported. I'm not sure if he feels a sense of job security, knowing that it is now illegal to fire him, but even so I don't think it's worth the price the rest of us are paying.
