I can't say if things have improved or not. What I can tell you is that in terms of student arrivals from Southeast Asia, those numbers have fallen off. Canada is now a very small market and a relatively insignificant destination for students from ASEAN to pursue their post-secondary education overseas. It may not be directly related to the visa question, but I suspect that the difficulty in getting visas is one factor in our lack of competitiveness in the international education market.
