Moving to US - house sale, Stock Options and RRSP

[jaloops]

Can I choose to leave my RRSP in Canada and file 8891 to invoke treaty?
Until I chose to withdraw. Why everyone says that IRS will tax my RRSP gains, when there is a way in treaty to get an exemption. Or am I reading it incorrectly.

Secondly, how is the gain calculated?

If I have 20,000 on Jan 1 and contributed 4,000 by Dec 31. In the mean time the there is also a 1,000 gain in overall value, resulting the Dec 31 statement on 25,000. How its calculated.

Invoke the traty and defer taxation.
