Some points to ponder
======================================================
Family reunification is a politically difficult question because of its crucial importance in many immigrant communities, particularly the suburban ridings around Toronto and Vancouver that handed the Conservatives a majority government in the past election. Mr. Kenney, speaking to a room of reporters primarily from Canadian ethnic media outlets, highlighted his government's decision to raise family reunification numbers substantially.
But he also pointed out that this may not be the case over the long term. He said his government's primary goal is to cut the backlog of applications that had pushed wait times beyond eight years in some cases. No new family reunification applications will be processed before 2014 to prevent the backlog from growing. In future, Mr. Kenney said, there will be a new family reunification program “that limits intake to a level that is fiscally sustainable.”

After reading the article, it seems they are quite content with the Supervisa system, where it doesn't cost them anything. Who knows what rules they will put in for future apps and/or might tweak the supervisa to 4 years ( my personal opinion ). Frankly, they created this backlog, and it seem,s while it won't be possible to clear everything by Nov, 2013 - late 2009 and 2010 apps will go on further as these numbers are really high.
