The up-front medical examination process is only available to spouses, common-law partners and dependent children. If any other members of the Family Class (for example, parents and grandparents) use the up-front medical examination process, the medical results will not be valid and the examination will have to be redone.
Canada’s Immigration and Refugee Protection Act changed the medical requirements for spouses, common-law partners, conjugal partners and dependent children, but these changes have not, so far, been extended to other members of the Family Class.
