Law / Moving to Poland from Canada - documentation questions [3]

Hey there,

I am planning on moving to Poland next year - 1 way ticket, not sure how long I will stay.

I was born in Poland, but pretty much spent the majority of my life in Canada. Graduated, made some money - and would like to live in Poland for a bit.

I don't really plan to work there - have enough passive income to live decently.

My questions are more related to documentation needed. I have a Canadian passport, probably need to get a Polish one. What about PESEL? do I need that for sure? What about opening a bank account in Poland? anyone know about wiring money from Canadian bank to Polish? Driving (how long can I use my Canadian driver's licence?)

Thanks for any help.
