Since the USA’s military is a gigantic force and all of Canada’s cities are right on the border, I think it’s safe to assume that the USA would pull it off. And since Canada is a developed country where citizens are used to and depend on comfort, I don’t see the population mounting a long term guerrilla war or insurgency on the scale of Iraq, Vietnam, Afghanistan, Northern Ireland. It’s not culturally a Canadian thing to do. There could be a degree of sustained civil and passive resistance, but no effective armed insurgency on a sustained level.
If you disagree with the above, you may debate it.
However, I’d like to mostly focus on the international response.
A thinly veiled war of aggression would draw condemnation but since the USA is the worlds most economically and militarily powerful country... would the international community do anything or just stick to rhetoric? What concrete actions would they take (if any)?

In light of the above, can the USA hold on to Canada or would it be forced to give it up so the international community stops its actions against America?
Or would the doctrine of might makes right prevail? Meaning that effectively, international laws and norms would be a travesty in such an eventuality and there would be NOTHING preventing the USA from just feasibly holding on to Canada?
What’s your take?
Let’s say, for the purposes of the scenario, the American voters support the invasion and annexation unless/until the consequences imposed by the international community become too problematic.
