Yes, they will require to provide your contract, payslips and probably reference letter. However, you can explain the reason why you can't provide a reference letter.I've got NOI from Ontario in the recent draw (13 Feb). I'm not including my current employment in the work experience section of my OINP application as I don't want to let my employer know that I'll be moving to Canada soon. However, my passport and resume will show that I am currently working with XXX company as YYY. Will Ontario ask me for my current employment reference letter????
