If you plan on returning to Lebanon to finish your last semester of university it sounds like you won’t meet the 6-12 months required to have your medical care covered.

You will either need to be prepared to pay for your healthcare costs of commit to living in Canada until you meet the residency period to qualify for coverage. Women who are postpartum and babies visit the doctor regularly so it becomes pretty obvious if someone doesn’t meet the residency requirement.
