Yes you do need it. All the information is on the CIC website. You can get PCC from USA online now. You just have to send your fingerprints by courier. Google FBI Identity History Summary, that's what you need.People,
Do I have to get PCC done from US where I lived for almost 12 years? I left US to return to India in May 2016. Am asking since I read somewhere that any country where stay is more than 6 months, PCC should be obtained.
I can get PCC here in India easily though.
