Certainly, a number of changes made in recent years, we think, have enhanced the timeliness and efficiency of our economic categories, particularly in managing intake in such a way as to be able to process applications more quickly. In recent years, we've also introduced the Canadian experience class to take maximum advantage of international students and other temporary foreign workers who have already demonstrated success in the Canadian labour market. This enables them to apply under a program that has very fast processing.
We've taken a number of steps to combat marriages of convenience. It's a great challenge in many of our missions abroad. I've worked in several of them—China, India, Russia, and Pakistan. The vast majority of marriages are genuine, but there is a significant amount of abuse of that program. Government has taken a number of steps in recent years to combat that, including a five-year bar on sponsoring someone else if you've been sponsored to Canada, and a two-year conditional status for people in new relationships, which requires them to maintain that relationship for a two-year period. Those are some of the changes that I think touch on your questions.
