This is a very detailed answer.
I want to know what if you get your PR, then get the PRTD to go abroad (study 1 year) and then come back and live in Canada for the next 4 years.
When will the person be questioned about their Residence Obligations? Once he is back after 1 year study or anytime they come back to the country or only at the end of the 5 years?
You don’t need any Canadian travel document to leave Canada. You need a PR card or PRTD to enter Canada by air.
