Maybe one that is more generic with regard to parents and grandparents is that the reply to request is much slower than in any other category. Also, the use of visas is done more slowly than most categories.
It often has to do, as somebody mentioned, with the medical. For instance, many parents and grandparents have to do a furtherance of the medical. It's something we notice fairly broadly. And many parents and grandparents never submit the follow-up application. Their children want them in Canada, but they don't want that. That happens as well.
