Based on the below clause from CIC website that is why I said is risky.xpressentry said:Not at all risky. Some PPs offer upfront medical. This will just give them less time to land in Canada once they receive COPR.
Medical exams
Do not complete any medical exam until you get an invitation to apply. You must have a medical exam before you can become a permanent resident. Your family members must also have one, even if they are not coming with you.
We will not approve your permanent resident application if your health:
is a danger to Canada’s public health or safety, or
would cause too much demand on health or social services in Canada.
When the panel physician completes the medical exam, they will either give you an information printout sheet, or an IMM 1017B Upfront Medical Report form. You must provide a copy the document they gave you when you apply online.
Note:The results of your exam must be valid at the time you submit your application for permanent residence. For this reason, it is a good idea to complete the exam as close as possible to the date you submit your online application.
