Similar questions - I applied for my husband on Sept 19, 2018 and just received the medical request (online) today too. I am confused about how this is related to the OWP - is the medical needed to approve OWP? Or does it just mean they are processing our file and will approve the OWP soon?
Medical is usually the last step. If you have applied from Inside Canada , then your OWP must follow in one or two days but you will have to complete medical in a defined time , which will be mentioned on permit. If you are applying from outside then it last step needed before they Issue workpermit.
