A functional democracy requires one critical element above all: attention, will and effort, where needed of the citizens. Everything else, rules, institutions, constitutions come distant second. No institution would be free of or resist corruption where there's no interest of citizens and/or will to make necessary changes.
And that is a major problem in this country. When writing a line into a dusting paper becomes enormous "can of worms" nobody is willing to touch with a stick; then no change is possible; when the only way to effect change is to write a program, allocate no less than in billions budget and pass it on to the bureaucracy, so the only change possible is trivial fixes at ever rising cost. The country has been in this fixing mode for decades, or maybe since Confederation. Even much beaver - celebrated national healthcare was not anywhere near a breakthrough among the peers (takes a minute to check the history) and has been in a permanent near-crisis mode for decades. Where citizens went to sleep democracy ages and degrades.
