We welcome this measure, as well. However, the problem will always remain, in our view, when considering the extent to which the applicant has retained ties to their country of origin.
For example, in the case of a sponsored person who is thinking of coming to Canada, it is understood that the application for residency has already been approved at the first stage and has been in process for some time. We can therefore imagine that this person doesn't have any major plans in their country of origin. They probably haven't just enrolled in a three-year program of study, but may be studying English or French. What may be considered a positive element in a sponsorship application may be seen as a negative element by a visa officer regarding the person's intentions for Canada or their country of origin.
I agree with Mr. Waldman that there should really be the presumption that these visas should be granted.
