While we (Canadians) certainly aren't happy with Trump's attack on Venezuela, Trump's threats against Canada, reneging on deals with Canada, threats against Greenland, and attacks on the US's domestic rule of law probably all carry more weight in this decision than that.
Despite the issues that Trump has caused Canada still does more trade with the US, on more favourable terms, than China...
We're generally against warmongering. We're definitely against invading another country with the purpose being to steal it's resources, and that's what explicitly what the attack was. We're weary of the military of our neighbor violating their own constitution, and their own laws, to invade another country without authorization from the appropriate civilian authorities because that sort of lawlessness doesn't tend to turn out well. We are concerned by the blatant murders and violation of the rules of the sea, and the rules of war that lead up to the invasion including the sinking of ships nowhere near the US posing no threat to the US and the murder of shipwrecked people. I'm sure the list goes on, but those are some headline concerns that come to mind quickly.
The actual operation was a military invasion of another country resulting in 3 figures worth of deaths - not merely a "capture" of someone - though the capture itself is concerning for the aforementioned reasons.
Obviously I can only actually speak for myself and there's no opinion that all 40 million of us agrees with, but I'm representing views here that I think a significant majority of Canadians hold. Or for some of the more in the weeds bits, a significant majority of politically aware Canadians hold. Not views I feel are particularly controversial.
