Obtaining Polish citizenship

Greetings all,
Hopefully this question wasn't already asked before.

I have become very interested in Poland recently, because my boyfriend is Polish and has expressed a desire to return to his native Kraków. From what he has told me, it seems that it is very hard to emigrate to Poland (besides the the language barrier, I understand that there are certain laws regarding immigration).
Now, I am currently a Canadian citizen, and my boyfriend has dual citizenship (Poland and Canada). I'm assuming that if we married, I could perhaps be entitled to Polish citizenship as well. But, because that possibility is still very far away, what difficulties do you think I would encounter or what steps should I undertake (besides learning the language) in order to obtain Polish citizenship?

Thanks for your help

I don't know details but It's not so difficult especially that you are from Canada and not some 3rd world country... you may visit and live here I think for 3 months without a visa and later I think If you find an employer, who want to hire you... but If you marry him before you leave then of course you may live here but you may apply for citizenship only after about 3 years of marriage.

Thanks for that, Grzegorz, that was very helpful! :D
