Roth 401(k) reporting for USC Resident in Canada

[stewak2]

USC resident in Canada commuting to work in USA.
In 2008 I chose Roth 401K option for own PP contributions since new protcol for 401(K) was not in effect yet. For 2009 I switched to standard 401K.
Roth 401(k) is funded with after tax income, gains not taxable in US but taxable in Canada. In this case, with the economic meltdown, I have a small loss this year. The money is invested in various US mutal funds.
The mutual fund units were not sold in 2008. I am assuming in this case I can't claim a loss to CCRA ( and nor would I report a gain, had there been one) since there was no actual sale of the mutual fund units to establish a value. Is this correct?
What reporting to CCRA is required?

Roth 401(k) funded by Cdn residents are NOT sheltered, even under the new treaty. only Roths or Roth401(K)s funded exclusively while resident in US retain their "Rothness".

So, they are simply investemnt accounts, subject to yearly taxation of distributions and cap gains. To trigger any cap losses, you need to sell the asset.

So you likely have cap gains distribution which is taxable, but no cap gains yet until you sell. By the way, cap gains distributions on mutual funds are straight income, not cap gains.
