Question about papers/passports?

[ck421]

This might be a really dumb question, but I have no idea what passport/paperwork I'm supposed to use when traveling between countries.

I have a US passport and a Canadian CoPR. So does that mean when I fly out of the US I use my US passport but when I arrive in Canada I use my CoPR?

For future travel between US/CA, do I continue to do this (US passport on US side, Canadian PR card on Canada side)?

Thanks in advance!

That's pretty much how it works, yes.
You can only use a COPR on land borders though.
