Not quite. It depends on how long you have been outside Canada, it is rolling 5 year period. Say you landed 01/01/02, you left Canada 01/01/03, (1 yr) returned to Canada 01/01/05, (2 yr) so between 01/01/05 and 01/01/08 you would have to remain for 2 years.
You have to work it out as to when you "landed" when you left, when you return and how much time you spent in Canada in each 5 year period.
