Guys! this "intent to reside" clause only applies during the citizenship application process.
Quote from the CIC webaite:
"You must declare your intent to reside during the citizenship application process.
To become a citizen, you must indicate your intention to:
live in Canada,
work outside Canada as a Crown servant, or
live abroad with certain family members who are Crown servants.
Once you become a Canadian citizen, you have the right to enter, remain in, or leave Canada, one of the basic rights of citizenship."
