It is in America too and opening it up is difficult in America, much easier in Canada. Let's say we elect a ceremonial president by direct vote, such a mandate would translate into political power that would challenge the PM who is only elected by his riding and party. If we stuck with the current method, the PM would appoint a president for a 5-year term as he does with the GG. There are other complications too like an increased role and different statues for first nations and provincial powers and prerogatives, like the not really settled "notwithstanding clause". Justin's old man Pierre was the only one in recent history who had the guts and brains to deal with it while keeping Quebec inside the country as it transformed from the Dominion of Canada to the country of Canada in the 1980s.
America has problems with democracy as currently constituted with rampant gerrymandering, a senate that represents geography and not people and a President not elected directly, but by a failed an obsolete electoral college, whose purpose was to keep Trump's out of power, not rubber stamp them in. It was a system set up by wealthy white men and partly designed to protect them and their wealth from the majority. As you know just getting rid of a bad idea like the second amendment would be impossible, at least for right now, so other work arounds must be devised.
