Dear friend,
I really appreciate your help.
When I came to Canada I left the address of a friend in the office of Immigration within the airport to receive the permanent resident card. This card never arrived. I went back to Brazil and had my doubts on staying in Canada because it was getting engaged and the person did not want to go to Canada. Now I changed my mind and I intend to get another chance. Thank you!
So you never received your PR card. In that case, you will need to apply for a new card.

If your friend is still in Canada, you could have your PR card sent to your friend and then forwarded to you. Alternatively, yes, you can apply for a PRTD. As long as you do it now, you should be fine. The closer you get to June 2013 the more likely you are to run into problems.

two days. That has to be the fastest processing time I've ever seen.
