Notes:
--> Data was not available for calendar years. Data entered in the year 2009 above represents the fiscal year 2008-2009, data entered in the year 2008 above represents the fiscal year 2007-2008, etc.
--> There have been two recent changes in methodology (the first affecting years starting in 1996, the second affecting years starting with 2003) which have caused fairly drastic re-estimations of some data points. For more information on the most recent change, please see: http://www.pc.gc.ca/docs/pc/rpts/rve-par/pdf/review_attend_vip-e.pdf.
