>There is no infrastructure to deport that many people.
The infrastructure existed to bring them in.
But disregarding that, it's easy.
We could do it with just planes easily but there are other options too.

Let's take Canada as an example.
The Evergreen G-class container ship capacity is 20,388 standard shipping containers.
We fit 30 pajeets into each shipping container.
So 20,388 x 30 = 611,640 PPS (Pajeets Per Ship)
4,000,000 Total Jeets / 611,640 PPS = ~6.5 trips.
Evergreen Marine owns 11 of those ships.
Rent 7 of them, and you'll be able to ship all pajeets back in one go.
