How to issue a Police Clearance Certificate for immigration if there's a possible case

Hi Eman,

I am K. R. D. C. G., currently live in Canada. I worked in UAE (Abu Dhabi & Ajman) from 2013 to 2016.

I would like to request a police clearance certificate for immigration purposes (For Canadian Permanent Residence).

I have tried twice online but have failed. In 2016, I had to go back to Sri Lanka due to my wife's medical situation (she was pregnant).

I quit my job & left the UAE without informing my employer, banks, landlord... etc. & I never went back. I have my Expired Emirates ID with me.

Please advise.
