Thanks, I'll do that then. I don't want urge them of course, but you're right, it's good to check if they got everything they need.Just email them ontarionominee@ontario.ca and ask if they have received your documents or if there are any technical issues and the documents were never delivered. Please state full name, case number etc etc. Refer to their website.
In my case, and during non-Covid times, it took 1 day to get into DIP after they received the documents.
