The statistics shows the time of the applications which have been completed in 2008, not those which still hold in backlog. It means even if the backlogs before Feb 27th,2008 have reached a tremendous level, the immigration officers only need to draw 20% applications from backlog while pay 80% his attention on new comers, then the statistics will still show that they have completed 80% applications in less than 34 months and only 20% applications have been completed over 34 months. The statistics is just a Canadian political trick. Don't take it seriously.
