i did it, used the same letter during the OINP program . i just attached an updated payslip of the current month to support it. I have not been questioned since. Good luck!I received ITA on 23rd of this month, I got a reference letter from my employer which is dated for 3rd June 2017 which I got from the HR for the Ontario Program, would the same letter suffice or do I need to get another new letter all together.
