Problem solved.

On behalf of California, we accept this proposal, and we accept Canada as our new federal government.

I also propose we officially refer to the remainder of the US as "Dumbfuckistan".

Colorado

You move that gods damned line to include Michigan. Right fucking now.

Nope. Move to a real blue state if you wanna come. MI has betrayed us too many times. We don't need that in New Canada.
The entirety of Michigan? Or should the Upper Peninsula stay a part of the US?

Seriously, why isn't the Canadian government offering US states to join them? It would be the perfect response to Trumps bullshit.

You want Canada to submit to the US? Hey Oregon, California, and the others, wanna join us instead?

If California leaves the US it would fucking bankrupt the US.

lol @ New Hampshire

Also, that would be about 37% of the US economy. California making the highest percentage at 14% of the US economy while New York would be in 2nd place at 8%. The least impactful would be Vermont with 0.2% (for got to include Rhode Island). However, I think this would wreck the world economy with the financial hub of the US (New York City) who manages the investments of world's reserve currency (dollar) would switch from US Dollar to Canadian Dollar. The US would also lose access to the Pacific and a considerable amount of military force stationed in the West Coast states.

Not to mention half of the important US ports. The states left would face a harsh reality when everything tripled in price as all the goods that used to be subsidized by the rich states are now hit with import taxes as well.
- As a resident of New England, I'm ok with all of these changes.

Excuse me but that incorporation of California, Oregon, Washington and British Columbia gets in the way of the glorious Long Chile Project. We shall be having words.

(By all means do take MN, CT and WDC tho.)

I think I speak for all Georgians when I say please include us too (I definitely do not)

I wonder if they could somehow carve out a thin path down to Atlanta and include us. Pls.
- Maybe we could go along the coast and include Savannah before grabbing Atlanta, I’d miss that city.

ITT: People pretending that Oregon, Michigan, and probably Washington don't have a huge population of total fuckos.

Carve a line down the coasts. You don't want the whole state. And while you're at it, take the lakes and Chicago

Canada also has its own population of total fucks. We keep them in the prairies. However like those states, it might be leaning more towards wanting that?

- So u r a source
  An ass source but one we shan’t judge

Accepting pleas from other comments here, Canada could get away with about this. And if they have the whole Pacific border, I'll also throw in Hawaii for free.
