With wahegurus mer he will be with you before that. Does your husband know anyone in Delhi, I would say that if he can stay in delhi after medical for a bit, because once medical is received and background check is done, he should get PPR request by early December. He can submit the passport at the high commission and get it back next day. once he's in Canada, you can apply for PR card and hopefully it will be given to you by March for sure. If not, then you can leave and you do have the option that if it is received in your absence and you have a family member coming to India, they can bring it for you. But clear that up with Cic once you have applied and ur about to leave in March. I don't imagine that there is a strict restriction on leaving the country without it, there must be a way around it.. what if there is an emergency, you wouldn't wait for a PR card to leave the country
