Yes we just scheduled a medical exam for ircc with our clinic that is approved by ircc (I live in Dallas, Texas so it was Neighborhood Medical). And we got a confirmation page from them which we uploaded.
As far as forms submitted we gave the following doc’s:
Birth certificate
Passport all pages of spouse
PCC
IMM0008
IMM5406
IMM5669
Marriage certificate
Letter of explanation
Medicals
Proof of payment
We used the ircc webform to send all the documents. Took us 4 separate queries.
