Thank you Leon and Baloo.
We have been exploring all our options, which are minimal and your advise seems like our best option.
We realize it's still a long shot, and we are at the mercy of the VO but given that we have asked his son's mother multiple times to allow their son to take a medical exam, and each time she has denied the request. We have two emails from my husband, to their son's mother and in both she had said that she will not allow it.
We hope that this, plus letters of support from his parents, and siblings to attest that he has made repeated requests, with no avail, will support our request.
Thanks to Qorax, here is some helpful information for anyone else who may be in a similiar situation
OP 2 Processing Members of the Family Class
2006-11-14 12
If these family members are genuinely unavailable or unwilling to be examined, the consequences
of not having them examined should be clearly explained to the applicant and reflected in the
CAIPS notes. Officers may wish to have applicants sign a statutory declaration indicating they
understand the consequences of failing to have the family member examined.
See also section 5.12, Exclusion from membership in the Family Class – R117(9)(d), R117(10)
and R117(11) below.

OM OP 03-19)
Under both the previous legislation and under IRPA, both the applicant and the applicant's family
members, whether accompanying or not, must meet the requirements of the legislation. There are
no exceptions to the requirement that all family members must be declared. With few exceptions,
this also means that all family members must be examined as part of the process for achieving
permanent residence.
Officers should be open to the possibility that a client may not be able to make a family member
available for examination. If an applicant has done everything in their power to have their family
member examined but has failed to do so, and the officer is satisfied that they are aware of the
consequences of this (i.e., no future sponsorship possible), then a refusal of their application for
non-compliance would not be appropriate.
Officers must decide on a case-by-case basis using common sense and good judgment whether
to proceed with an application even if all family members have not been examined. Some
scenarios where this may likely occur include where an ex-spouse refuses to allow a child to be
examined or an overage dependant refuses to be examined. Proceeding in this way should be a
last resort and only after the officer is convinced that the applicant cannot make the family
member available
