Hi not sure if it applicable at all. As far as I remember, the passport and travel documents youve had at the time you became a Permanent resident. So if you arrived in canada in 2013,
item # 10.a) Where have you lived during your eligibility period? Please list all addresses inside and ourside of Canada. Your addresses must cover the entire eligibility period. If there are gaps or missing periods your application will be returned to you.
b) In the past four years, were you in another country (other than Canada) for a total of 183 days or more?
If yes, list each country in the chart below. You must provide a police certificate for each country where you have been present for 183 days or more. If you cannot get a police certificate, tell us why below.
In my own interpretation of the details being asked, the 183 days is actually not made up, because if you have "permanently resided" for over 183 days outside Canada, then that is actually considered as being really "Out" of Canada. The same number of days, as a Canadian, I would lose my OHIP, should I be out of the country for more than that number of days.
My parents travel a lot, BUT this does not mean that they have changed residence.
I totally agree with using your own judgement, as to how you would define "Residence" in contrast to just Travelling.
