Actually how did you get in? If you applied with PRTD, then you should get visa of either R-1 or RC-1.I am 21 years now. Also, I already applied for renewal under H&C. Do you have an idea how long it might take?
From searching in this forum, I think these are the differences.
(sorry, I copied it from one of the senior member's post but I forgot to save the link)
R-1 means that you meet the Residency obligation (either by spending 2 of past 5 years in Canada, or living with Canadian citizen spouse).
RC-1 means you didn't meet the RO, but had a valid H&C reason that was approved to overcome the RO
So that will determine how long will you need to wait for the PR card.
