That's exactly it, isn't it? Claiming you have rule of law while being unable to secure prosecutions makes it a farce.
It's questionable if that exists in Canada given the system that's currently in place.
Look at the results of the most recent federal election, for example: https://en.wikipedia.org/wiki/2021_Canadian_federal_election
A party that received 32.62% of the popular vote got 160 seats in the House of Commons, while another party that received 33.74% of the vote got only 119 seats.
A party that received only 7.64% of the votes got 32 seats, while another party that received 17.82% of the vote got only 25 seats.
A party that received 2.33% of the votes got 2 seats, while another party that received 4.94% of the vote got no seats.
With a votes-to-seats situation like that, there are a lot of Canadians who don't have proper representation in the House of Commons, or in some cases, effectively none at all.
It's no surprise that the voter turnout wasn't even 63%; many Canadians are completely disillusioned with how the current system works, and don't feel that any of the parties can offer them meaningful representation.
Seems like that's exactly what rule of law should entail: laws so strictly enforced that people can't be prosecuted when the prosecution is botched because doing so would... violate the rule of law.
So if anything, this further reinforces the idea that Canada hews closely to its laws than not.
If the prosecution fails to make their case, either through incompetence, or simply being outwitted by the defense, that's life. That's how the system as a whole should function. That is rule of law.
Fuck everything about that.
