Hi Canuck,
Yes i went through the forum. But not really sure if any supporting document is to be provided for residency obligation or not. What is supposed to be answered in the forms and if supporting documents are to be provided.
A copy of your CoPR should be submitted with the PR TD. On its face this document shows a relatively new PR's compliance with the PR Residency Obligation.
Residence and travel history should still be provided, as specified in the form and instructions, but since the CoPR documents the date of landing, reference to a calendar definitively proves the new PR is in compliance.
Indeed, the CoPR shows a PR's compliance with the RO UNTIL the third year anniversary of the day the PR landed (that is, until the 3rd year anniversary of landing a PR is definitely in compliance no matter how many days present or absent, since there are still at least 730 more days left until the fifth year anniversary). However, obviously, cutting-it-that-close, or anywhere near that close, is RISKY enough to be a bad idea . . . but for at least the first couple years after landing, a copy of the CoPR sufficiently documents compliance with the PR RO.
