Your country invited a war criminal, ordered their soldiers to kneel to him, and then tried to negotiate peace while said war criminal was bombing the citizens of the country he attacked. All the while not having invited the leaders of that country to the table. Your leadership demonstrated a weakness not seen since Chamberlain's attempts to appease Hitler. Then there was the botched bombing of Iranian Nuclear facilities, another blunder seen as caving to Israeli pressure. Canada may be reliant on America for now, just like NATO and the EU is, but - Canada and Canadians are willing to suffer economic damage to break free of their dependence on a weakening neighbour who cannot be trusted. The damage to America will take time to set in, but consider how much your neighbours actually hate you: they spurned a conservative shoe in and voted to keep their existing shitshow of a government PURELY because the conservative sounded a little like Trump. But none of that is going to bother you, so let me frame this in a way you might understand;
Imagine if Americans like you had voted for Kamala Harris just to spite Trudeau. THAT is the level of distrust Canadians hold for your leadership.
