I like the 3/5 rule, but it needs to be worded like this: To apply for Citizenship, please wait 5 years, renew your PR card, and see if you have been in Canada the required amount of days totaling 3 years or more.
It would cut down on the amount of apps that become short on days because all the potential applicants see is the "3 years" part and do not continue to read onward.
Also, the 3/5 part would have helped me greatly in that during my interview after my test, the rest of my travels in that first year (if it was at 5) would have been documented more positively with passport stamps in my passport.
This kind of shows how the previous government was not very trusting of it's residents and citizens and it's obsession with keeping all of us "in line".
Now if they would just tell the citizenship officers to get with modern times and stop looking for passport stamps when the majority of nations don't stamp them any more....thats why we have computers and multi-jurisdictional cooperation among all Canadian agencies.
Done now
