Both recent and historical evidence does not really support this claim. It is very very very easy to find many examples of governments breaking the law for their own benefit.
I don’t think it was the Canadian government either, but your logic does not seem good.
And that’s not even taking into account that once trust is broken there are likely many more instances that aren’t known.
Neither of those would explain a government entity hacking this website to leak this data in an attempt to benefit the government.
I can't produce evidence that there isn't a history of actions like this, since my evidence really is just the lack of evidence. Thus I'd ask you to produce the "ample evidence" you claim exists.

That said, I don't think the state was the responsible party for this attack.
The current premier's father had feds planting explosive in people’s mailboxes [0] and tried to pin it on some political group he didn’t like back in the 70’s. Talk about a coincidence.

No.
The hack was obviously politically motivated, beyond that, nothing here points towards it being state sponsored. Non-state actors are equally motivated by the timing.
The idea that the Canadian government hacked GiveSendGo is also frankly ridiculous. Our government just isn't that lawless, and they could almost certainly get this data via legal means.
