You're pointing at one emergency measure, but that's not the equilibrium, it's an outlier. The US has its own overreach—civil asset forfeiture, no-fly lists, indefinite detention—without the same political accountability. From a game-theory view, the difference is structural: in Canada, a PM who abuses power faces a confidence vote and an early election. In the US, a president can hide behind a divided Congress and gridlock, so nobody pays the price. That accountability mechanism makes abuse less sustainable over time. Which system better deters it, on average? That's the payoff that matters.
