…by 2, sure. The net result would be that you’d now need 271 EVs to win.
I don’t think there’s a scenario where Canada joining the US works out to the magacult’s benefit.
oh, true if Canada was one state as opposed to 11.
Oh, that’s true. I guess I had assumed they would expand the House. Which is probably a reasonable assumption, since Congress would be unlikely to vote to abolish the districts of dozens of its members. But you’re right that it wouldn’t automatically happen just by admitting the new State of Trumpstaninople (fka Canada).
Why change it, I can’t say; MAGA just likes it that way.
If the US really took over Canada I expect the methodology would be closer to the occupation of Iraq than turning it into one or more co-equal states. Bullets not ballots is what they’d get.
Realistically, I would expect Canada to insist on at least 6 states: Atlantic, Quebec, Ontario, Prairies, BC, Northland. (Although the three territories are no provinces they have governments and send full MPs to parliament.) We would end up with 36 Representatives and 12 Senators, mostly Democrats. Trump likely doesn’t realize how deplored he is here.
I see no reason the single-payer health system couldn’t continue. It is administered by the provinces and I don’t it violating any US law. In fact, I see it as a worm that would gradually eat its way into more and more states. No southern states of course, since they would see blacks as the main beneficiaries. Since the US lacks an official language, I see no problem with Quebec remaining French. Although some of the more rigid laws on the use of English might fall.
I would hate it for another reason. As a US citizen, I have the joy of filling out US tax returns. But my taxes paid here give me tax credit credit that easily wipes out an US taxes owed. I would lose that credit.
Thirty years ago, who would have figured we would be living in the Fallout timeline?
Yes, I’m quite looking forward to losing my free health care and my country becoming infested with guns, as well as the loss of our distinctive values and heritage. 
There may have been a time, maybe back in the Kennedy era, when I might have thought that merging with the US was at least conceivable. Little did I know that the travesty of Vietnam would soon happen; as a Boomer, I was of prime draft age. Today, Trump and his acolytes are the very personifications of why Canadians want as little to do with the US as possible. We can hardly believe what’s happening to our former friend and neighbour.
My answer to the OP:
FUCK TRUMP And any of his syncophants who talk this up.
and
FUCK Traitor O’Leary while we’re at it.
And I’m not very keen on Americans who think this is something to joke about.
Why on earth would we do that?
See above.
You have to admit, Trump has done more for national unity than anything in the last decade at least. When have you seen Trudeau, Poilivevre, and Singh all on the same side of an issue?
Gallows humor. It’s all we have right now.
Don’t forget about manifest destiny. It seems like Trump and/or his ilk actually bothered to read a history book for once.
My experience is that, even though we generally consider ourselves lucky to have the US as neighbours, we don’t even like being mistaken for Americans, let alone the thought of actually being them.
Kinda what I said, but phrased better! 
Let’s pray this is all a matter of idle threats. But if not:
Trump’s threats to much weaker countries can only be achieved militarily. Even if U.S. casualties were low, MAGA America would be angry that Canada had put up any resistance, and hardly be in the mood to give up the slightest bit of political power to the vanquished. The idea that Canadians would be allowed more rights in the United States than, say, native born residents of American Samoa (U.S. nationals, but not American citizens), is preposterous. The Canadians would be treated worse. I can’t believe Trump would let defeated Canadians work in the United States – that goes against his anti-migrant stance.
P.S. Even if the impossible happened, and the U.S. defeat of Canada was utterly bloodless, the Republicans are not going to admit a state likely to vote Democratic.
Canada is remote enough from the US, that it resides in or near joke territory. Other countries are even more remote.
With that in mind, the Canadian national security community needs to think about what they should do if the US invades Panama. They can file UN Security Council objections of course, which would be vetoed by the US. They can offer military assistance to Panama. They can encourage Europe to assist Panama. They can forge closer ties Colombia, who would offer military assistance to Panama. They could offer sanctuary for US anti-war/pro-democracy protestors.
I don’t think this is a complete hijack. The President-elect of the most powerful military in the world is expressing indifference to international borders, overturning a cornerstone of international relations that the US worked very hard to construct. You can say a lot about how bad the Iraq War was, but it to be clear it was not an effort to take over territory.
There always will be a potential Petain or Quisling.
After the impossible happens - it would be an interesting assumption that there will still either be voting or a Democratic party allowed.
The USA isn’t going to invade Canada.
Probably not until after Trump, Mexico will come first. But the fascists will come after Canada eventually.
