Overwintering Hawk Moths?

[EE]

Today I found a GIGANTIC tomato hookworm on a tomatillo plant. I must
admit that last year I offed a whole generation of them early in the
summer with my garden shears. But this one is just too big to kill and
it's the end of a pathetic growing season anyway. It's about 7 cm long
stretched out, and is black with orange markings. Anybody know which
Manduca this might be?

How would one overwinter such a creature? Do I provide a pot of dirt?

We're near Toronto, ON.

Thanks in advance for any suggestions,
