Hi ,we got pr Canada in march 2015,landed for one week in July 2015,immigration officer at airport told us that we can't get pr card by updating friends Canadian address ,bcz for getting pr card person should be physically present in Canada till processing of pr card,so we didn't get pr card.Now we r planning to move permanently to Canada by travel document..but problem is we didn't apply for SIN during our last visit.our COPR will become more than one year old when we shift there and processing of pr card will take 3 mths...then how will we get SIN..so if we apply SIN via mail by sending COPR original is it safe..
