I don't think the changes being made to the sponsorship requirements of the parent and grandparent category would have a direct impact on the health of sponsored immigrants under that category, given that all permanent residents have full access to Canadian medical care and so forth. The changes in the proposed new regulations do increase the financial requirements for sponsorship. The regulations have been pre-published and have not yet seen final publication. So based on the pre-published regulations, that will ensure there is adequate financial support for persons sponsored under the category. And the pre-published regulations also propose an extension of the sponsorship period from 10 years to 20 years, again to ensure that elderly individuals coming to Canada and obtaining permanent resident status have that full support from their family members.
