One of the ETFs being shutdown is the iShares Brazil Fund XBZ - all it does is hold XWZ which is the US listed iShares Brazil ETF.  I own XBZ and it is currently underwater so I have a capital loss.  

How does CRA feel if I sell XBZ and buy XWZ?  Do they still deem that to be a superficial loss?  The sale decision has been forced upon me by Blackrock.  I could wait until they shut down the fund and distribute to me but with that I somewhat lose control of the process and I could be out of the market for a few days.
