AIP is right before being approved for PR so often you get PR before getting the documentation proving you have AIP and meeting withthe right person and right location or Service Ontario. It is also a huge hassle so many just wait until they get PR. They will still not have OHIP for the majority of the sponsorship process and can’t predict when they will get AIP or be approved. If you have chronic health issues inland sponsorship may not be the best route. If you plan on getting pregnant I would delay for many reasons. No healthcare coverage so you are looking at 10-20k+ out of pocket, you won’t qualify for parental leave having never worked in Canada, It is harder to get a job if pregnant, etc.
