See the following note from IRCC:where can I confirm this? This is my situation. I worked in the UAE and got PCC for my PR application then I moved in Canada (Didnt visit the UAE after landing). With this, I dont need PCC anymore?
Note: If you were in your country of origin immediately prior to becoming a permanent resident and landing in Canada and this time falls within this four year period, you are NOT required to provide a police certificate. Please indicate this in the explanation box.
