Moving to Canada during Process

Me (Canadian, Sponsor) and partner (Irish, PA) have flights booked for April 3rd. We’re starting the application now.

I know we can move to Canada while it’s being processed and he should be able to apply for the OWP while in Canada but will we get flagged or denied entry if he has his stuff with him? We’re only taking two suitcases. He has enough to show he can buy a return flight as that doesn’t seem to be a requirement for Canada with dual intent.

Anyone been through this before? I just want to make sure we will be ok to go back in. He has a valid eTA currently.

We’re common law btw
