I had a criminal conviction in Poland in the past. Can I travel to Canada now that the visa requirement has been lifted?
No, because you may be inadmissible to Canada. You should visit the Visa Section in Warsaw along with your original conviction and a recent police certificate from the Polish authorities. We will assess the information and provide you with an opinion regarding your admissibility to Canada. If you travel to Canada, you risk being turned back to Poland at a Canadian port of entry.
