Outland PR documentation to receive while in Canada?

[gbozz1]

If we come to Canada after starting the outland PR process (with wife on a 6 mnth tourist visa), is there any documentation that MUST be done in Korea (where are now) after process starts or paper documentation sent from Canada to Korea that we need to be sure is sent to the address of where we will be temporarily staying at in Canada?

Is it pretty straightforward to notify the address change, etc to Canada immigration once we are in Canada, or is at all moot because the rest of the PR process is done via email correspondence anyways?

Thanks!
