Hi, welcome to the board!
Here is the website for the Polish Embassy in Canada: http://www.polishembassy.ca/ and here is information about foreigners working in Poland: http://www.infoobywatel.gov.pl/english/index.html
After some more searching, I found this site: http://www.jobmonkey.com/teaching/europe/html/expats_in_poland.html
"Of the expatriates who have settled in Poland, many seem to integrate better into the local communities and get involved in local activities than they do in places like Prague and Budapest, where it's relatively easy to avoid the locals by hanging out in places where only expats congregate. So if you want to find your own little niche among an ordinarily friendly and open people, Poland might be just the place for you. It will definitely challenge you in ways that the other countries won't simply because it seems more of a frontier than the Czech Republic or Hungary."
Sounds like a great place! Good Luck
