What is the process of PR while in Canada working on work permit

Hi All,

My Company is filing for work permit through Intra company transfer.

I am already in process of preparing for PR through express entry and got my education evaluation done and its equivalent to Canadian Master. Currently waiting for IELTS exam.

Do the process for PR change in any way while i am already in Canada with work permit.

Based on my IELTS result if i get ITA . Post submission of all documents what’s the approx time it takes to get the PR. Does it differ if its filed from Canada which will in my case.
