I'm not sure I'm following 100% your question, but I think you mean what if the government is so unpopular that the country is close to a revolution from its citizens?
This doesn't really makes sense to me in a liberal democracy like Canada. Every few years, the citizen get to replace the government with another if they're unhappy with the current one. The opposition are able to have a vote to cast out the current prime minister if they want. The governor general, at any point, if it senses the people are no longer favorable to the government can kick off a new election as well. On top of that, the government is using force within the established limits of the laws and Charter of Rights of the country that are already pre-agreed upon, and the force it is using is itself in order to enforce the laws of the country from being broken, which is kind of its job as a government.
> More to the point, the government are free to follow up the threat in a court case in front of a judge, and the fact that they didn’t is the problem
I'm not really following your point? The government is also allowed to enforce laws, and they can later be trialed. Police does this all the time, they will intervene and perform an arrest, and the trial in front of the court happens after. They are also free to enact the Emergency Act in the case of an Emergency as they did.
The funds from bank accounts are frozen, not taken. What will happen next is they will either be released, or a court case can start and decide what to do with the funds.
